Pressure, atmospheric water heating system with a detailed comparison of pressure 1, pressure boiler heating system in accordance with comparative analysis of the boiler pressure level, the pressure inside the hot vertical water boiler for sale in asia large pressure is necessary to provide a safety valve, pressure gauge, thermometer, and other auxiliary tool. Since the internal pressure of pressurized hot water boiler is always filled with water, it is not necessary to provide water level gauge, pressure hot water boiler equipped with a thermometer and a water level gauge only, due to the communication, between the boiler pressure hot water boiler and the atmosphere internal pressure is boiling. er and thermometer. Equal to the atmospheric pressure, there is no explosion of the boiler, there is no need to install a safety valve or pressure gauge. Thus, the pressurized boiler heat better than the internal pressure, the requirements of facilities is also higher, there are some risks to the safety of the boiler. The boiler pressure due to internal pressure and atmospheric same security risk is very low, less demanding facilities, but the operational efficiency has to be improved. 2. The circulating pump Comparative contrast, more advanced pressurized water heating system, using the circulating pump main apparatus can be sent to the boiler water system, which generally can be maintained at the operating temperature effect 70 ℃, water pump can be selected . Pressure can be controlled circulating pump water heating system vascular resistance, and to maintain the pressure inside the boiler, in order to protect the water vaporized in the boiler does not occur. (Water gasification boiler First, it will increase the internal pressure of the boiler, increase the risk of explosion; the second is endothermic cooling water evaporation, increases heat loss inside the boiler) and at atmospheric pressure boiler heating system circulating pump, mainly through the boiler water extraction, its working temperature is usually about 95 deg.] C, it is necessary to select the heat pump, which is capable of overcoming the major resistance of the outer loop, but also to overcome the resistance of the backwater control valve. In pressure boiler heating system, due to the relatively low pressure water circulation pump, therefore, very prone to cavitation problems, we can say the inner workings of the environment is very bad. China's relevant scholars these two boiler heating system were analyzed and compared, including mass flow contrast and contrast power. After comparing the work found in the same heating project, the circulating pump energy heating system boiler pressure loss is large. The larger the size of the heating system, the greater the heating area terrain changes, the greater the difference between the two, which is the higher pressure boiler heating system energy consumption. In addition, due to the cavitation problem occurs pressure boiler heating system, therefore, we can not use water pump. 3. Comparison of the effect of heating hot water boiler heating system will eventually be implemented in the heating effect, heating under the same conditions, the performance of the boiler with the capacity of the heating system pressure higher than atmospheric water heating system, therefore, the boiler pressure poor heating effect of heating systems, it must adopt the operation in the form of low temperature for long. Typically, in the same environment, and the heating capacity of the boiler on the basis of the effect of atmospheric heating boiler heating system can only reach about 80% of the water heating system pressure; 11 / December, atmospheric temperature than the heating boiler heating system pressure low temperature heating boiler heating system 10 ℃, said heating effect can be very different. 4. Compare the above to improve safety too, due to the pressure bearing boiler heating system is relatively large, with a certain degree of explosion risk, therefore, pressure hot water boiler manufacturing must comply with national production standards required in the production process supervised check. Before pressure hot water boiler applications, device management need to be registered, and need to be put into application performance check in periodically, hire a professional boiler technician to carry out inspections. Visible, pressure boiler heating system application and maintenance costs are relatively high. For pressure boiler heating system, because connected to the atmosphere, and therefore, there is no pressure difference, no explosion risk, high security operation. Therefore, pressure boiler heating system is not included in the scope of regulation to force, it will not require complex management procedures pressure boilers, low running costs and more. 5. Applications parity pressure boiler can not only supply the high-temperature water, but also to supply low-temperature water. However, pressure boiler heating system capable of supplying only a low temperature below 100 deg.] C in water. 10 years ago, most of the area or businesses are using low-temperature water heating, but heating demand as people continue to increase, energy saving ideas popular, high-temperature hot water boiler has become an inevitable trend. Since the pressure boiler heating system can only provide low-temperature water, and therefore, are applied in conventional cells, that is, multi-storey buildings; high-rise buildings typically employ pressurized heating boiler heating system. Due to pressure boiler heating system no risk of explosion, not mandatory rules and regulations related constraints, therefore, it can be installed in the building basement, especially in densely populated areas, can effectively reduce the loss of heat transfer problems in the multi layer architecture has a distinct advantage.

The operating principle steam boiler steam boiler is a function of the modern electronic technology with traditional boilers organic combination of new industrial products. It features traditional boiler with electronic manner. Revolutionized the traditional way of heating boiler, the traditional way of heat produced by combustion into electrical quietly carried out. Environmentally friendly and energy-saving thermal efficiency up to 98% of his relatively conventional electric tube boiler can save 20-30% have adopted the way of separation of water in the design of internal and external insulation, external water go inside to go electric, the safety factor by a few orders of magnitude.

Henan Provincial Government to respond positively to meeting the spirit of the "Blue Sky Battle Action Plan", in mid-September, the issuance of "three-year action plan for pollution prevention and control campaign of Henan Province (2018-2020 years)" ( "Program"), under provincial jurisdiction, provincial tube county (city) people's government and provincial government departments need to be strictly enforced.

A gradual reduction of the total coal consumption

1, and strictly control the total coal consumption. Strictly implement the "People's Government of Henan Province, Henan Province, on the issuance of" Thirteen Five "total coal consumption control notification program of work." Strengthen the electricity, coal, steel, chemicals, nonferrous metals, building materials and other key industries of coal consumption reduction measures to eliminate a number of energy consumption is higher than the national average of inefficient capacity.

2, to enhance coal project access threshold. In principle ban on new or expanded production capacity of pure coal, coal, iron and steel, electrolytic aluminum, cement, glass, traditional coal chemical, coke overcapacity of traditional industries, the province's non-new chemical park.

3, an alternative embodiment of the coal reduction. Strictly implement the "coal project in Henan coal consumption of alternative management (Interim) Measures", all new construction, renovation, expansion project be implemented coal coal reduction or equivalent alternative. For failure to complete the annual coal consumption reduction objectives of local, regional limits approved implementation of coal projects. In addition to cogeneration projects, the province no longer approve new production of "Thirteen Five" period coal-fired power projects.

Second, build the province's clean heating system

1, the basic realization of full coverage of urban central heating. Based on existing resources and central heating facilities, the existing large-scale heat sources and central heating pipe network in the area, in-depth investigation heating demand, and promote the rich heating capacity extends to reasonable radius and root out the potential heating, heating reduce blind spots.

2, vigorously promote clean energy for heating. Central heating pipe network coverage area, the power supply and secure place, the implementation of clean energy heating engineering, accelerate the promotion of ground source, water and air source heat pump technology, building a number of distributed energy heating project; in the natural gas pipeline network to cover the area, on the premise of the implementation of gas supply contracts, ordered the construction of gas-fired boiler room, natural gas distributed energy projects.

3, strengthen clean coal quality control. Continued to organize provincial, city, county, township (neighborhood) and village (community) scattered five coal-burning governance special inspection operations, according to the law to crack down on sales of substandard clean coal behavior.

Third, the development of industrial coal-fired facilities Chaigai

By the year 2020, and out of the basic ban coal stove cogeneration heating pipe network coverage range fired heating, drying furnace (kiln); out hearth furnace diameter of 3 meters fuels gas generator, increase fertilizer industry fixed bed coal gasifier intermittent reform efforts; focus on the use of gas furnace industrial park, they will not have to switch to natural conditions, should build a unified clean coal gas central principle; prohibition blended with high-sulfur petroleum coke.

Fourth, to promote the comprehensive improvement of coal-fired boilers

Demolition and gradually expand the boiler clean energy transformation of coal-fired range. Before the end of 2020, the province basically eliminated 35 tons of steam / h and coal-fired boilers.

Boiler Chaigai funding awards complement the implementation of the way decreasing year by year:

The completion of the coal-fired boilers Chaigai before the end of October 2018, giving 60,000 yuan / tons of steam financial awards complement;

The completion of the coal-fired boilers Chaigai before the end of October 2019, giving 40,000 yuan / tons of steam financial awards complement;

The completion of the coal-fired boiler Chaigai after the end of October 2019, no longer give financial awards complement.

Boiler and steam should have what conditions? (1) normal boiler plant, (2) a suitable material thickness, stable combustion furnace. (3) a pressure slightly lower than the superheated vapor pressure of the main steam pipe, generally 0.05 ~ 0.1MPa. (4) steam temperature between 370 ~ 400OC. (5) Drum Level of about -50mm. (6) steam quality qualified. (7) the tube conduit has fully warmed. Boiler Water Level Indicator How to deal with the failure of the boiler drum water level how to deal with failure? (1) such as boiler drum water level table has a damaged: damage to the door immediately closed water table level, valve, open its doors hydrophobic. With another drum water level meter to monitor the normal water level in the drum. Take urgent measures to repair or replace damaged water gauge. (2) Drum Level two tables are damaged, but the boiler feed water automatically, water gauge differential pressure within one hour and the front drum level table has proofreading, confirmed that the correct and reliable, with reference to the feed water and steam flow meter instructions, continue to run for 20 minutes. In both cases, the squad leader should report the value of long, to maintain the stability of the boiler load, and to take urgent measures to replace the drum level table. (3) If the two tables are damaged drum water level, water level gauge while the differential pressure is unreliable operation, should the emergency shutdown process. How to determine the boiler load plummeted? It plummeted What is the reason? What should I do? Come the following: boiler load plummeted phenomena: (1) steam flow plummeted, steam pressure soaring. (2) found the treatment is not timely boiler safety valve operating will result. (3) decreased instantaneous boiler water level then rises, a high level alarm signal. When the safety valve seat, the water level decreased rapidly, may cause low water level alarm signal. (4) When the transmission switch trip, to swing each of the auxiliary ammeter have abnormally, the flash lighting. Boiler load sharply reasons: (1) an outer line switch trips. (2) steam turbine emergency stop. (3) Isolation Valve core valve or the main valve off. Plummeted boiler load process: (1) The table indicates drum water level, steam and feedwater flow meter, automatic to manual feed water, to adjust the water level. (2) The rise and decline in steam pressure load, and timely Kohiki off, air supply, stop grate, holding BOILERS, open superheater hydrophobic. (3) timely adjustment of desuperheating water gate, so that the steam temperature is normal. (4) If the discovery process is not timely, the pressure exceeds the safety valve operating pressure, and when the security gate does not move, should Stokes Exhaust electric door open, until the normal pressure. (5) make contact with a load preparation, monitor and report the value of long. (6) accident, checked the action over the security door situation, is closed tight. When the boiler drum level is unknown how the "waters"?
