WNS Fire Tube Vacuum Hot Water Boiler

2. boiler technology energy-saving measures (1) strengthen the technological transformation of inefficient boilers. Due to our limited economic base, not all older boilers have been updated. For updates not included in the scope, efficiency is not high but there are more defective boiler should strengthen technological innovation. Technological transformation of industrial boilers, should try to achieve a multi-effect of the change is necessary to improve the thermal efficiency to save fuel, but also to increase output, reduce pollution and achieve civilized production, but also to adapt to burning low quality coal. (2) boiler should make full use of frequency control technology. When selecting the boiler pump and fans, are considered certain margin in the rated load, so that in fact the boiler operation, the fan and the pump flow is less than the rated flow equipment, are required to be adjusted. Is adjusted by adjusting the throttle in the past, i.e., OFF or the throttle opening degree smaller Importers baffles, the flow rate is reduced, but not significantly reduced motor power. Frequency is reduced by the drive motor speed, the motor output power decreases. Frequency control for pumps and fans, general can save 30% to 40%, the investment can be recovered through two heating season, at the same time, due to the deceleration operation, reducing mechanical wear and extend bearing life, improved mechanical reliability sex. (3) the rational use of automatic control technology boiler. Boiler operation, automatic control can improve boiler efficiency, energy conservation. In recent years, automatic control technology and the rapid development of computer control, and more Sheung drum water level automatic control device, automatic control and computer control the combustion process in the oil and gas boilers more general application, for Stoker, some boiler monitoring the use of computer rooms, manual adjustment is also received good results. Boiler automatic control and computer monitoring instruments should be simple, practical principle. (4) promote the use of heat pipe heat exchanger. At present, the domestic part of the boiler flue gas temperature is too high, a large heat losses, reduces the thermal efficiency of the boiler. Can effectively heat pipe heat exchanger flue gas heat recovery boiler, the gas - liquid heat pipe heat exchanger is mounted in the boiler feedwater heating flue, significant energy saving effect, only one heating season investment can be recovered for a heat exchanger. (5) using the condensing heat recovery boiler technology. In conventional boilers, the exhaust gas temperature is generally 160 ~ 250 ℃, water vapor in the flue gas is still in a superheated state, it can not be condensed into liquid water and release latent heat of vaporization. As we all know, the thermal efficiency of the boiler low calorific value fuel is calculated, it does not consider heat loss in a high latent heat of vaporization of the fuel heating value. Thus the thermal efficiency of the conventional boiler generally only 87% to 91%. Waste heat recovery boiler is condensed, to which the exhaust gas temperature is reduced to 50 ~ 70 ℃, full recovery of the latent heat sensible heat of flue gas and water vapor to enhance the thermal efficiency, the condensed water can be recycled. (6) reasonable steam accumulator. The steam accumulator is an energy save type apparatus, steam accumulator principle is that when the boiler load is reduced, the excess steam is fed into the boiler the steam accumulator and the steam under a pressure becomes high pressure saturated water. When the heat load increases, the amount of evaporation in short supply when the boiler, reducing the pressure accumulator, i.e., the high-pressure saturated water is separated into a low pressure saturated steam and water vapor produced by the user for use. Steam accumulator fuel savings typically 5% to 15%. (7) The vacuum deaerator technology. Vacuum deaerator oxygen is an energy save type method. Currently, oxygen supply and drainage method use large industrial boiler thermal oxygen atmosphere. This method of heating water to boiling temperature should at atmospheric pressure, oxygen in the water to drain away. Thermal oxygen atmosphere has two shortcomings. First, the atmospheric pressure boiling temperature, consumes a lot of steam, the boiler to reduce the effective use of heat. A 10t / h boiler feed water heated from 60 deg.] C to 105 ℃, steam consumption about 0.7t / h. Second, because the temperature of the boiler feed water economizer to improve the average water temperature increase, reduce heat economizer temperature, exhaust gas temperature increases, heat losses increase. These two points are the thermal efficiency decreases. And when the vacuum deaerator, the degree of vacuum is maintained at 7.999kPa (60mmHg), as long as the water temperature is heated to 60 deg.] C can achieve the purpose of oxygen. This not only saves steam and reduces exhaust losses, thereby improving the thermal efficiency of the boiler. (8) boiler water treatment technology to promote imports. It is estimated that imports of internal boiler every knot 1mm of scale, the overall thermal efficiency of a decline of 3%, and imports affect the safe operation of the boiler, through effective water treatment technology and cleaning technology, imports of non-boiler scale operation.

1. Complete gas boiler heating energy efficient gas boiler heating power key to progress, energy savings should follow the completion of the following two criteria. First, advances in gas boiler power. Here said boiler power refers to the power of this season boiler boiler group or groups. Power gas-fired boiler primary season progress through two ways to complete. First, during the heating, the boiler will try to start and stop times, idle time reduction. Thus these operations will form part of a certain level of gas and heat consumption. Second, the appropriate share of the air conditioning hybrid and natural gas can be burned together with the power of progress, reducing natural gas consumption. Second, advances in power delivery network. In the pipeline transit, insulation, leak, hydraulic imbalance resulting in heat loss is the primary factor affecting the delivery of power. In the heat loss, the heating system, the vertical offset, the horizontal offset energy external network formed by the loss of most severe. Thus, to complete the power-saving, it is necessary to start from the presence of these disorders conditions.

2. The gas condensing boiler heating energy-saving skills 1. Skills condensate skills is the primary means of useful skills to complete the power-saving gas-fired boiler. Element in the presence of hydrogen rich natural gas, the natural gas during incineration may generate a lot of water vapor. In the exhaust process, the temperature rises, the water vapor is condensed can not be completed, a lot of thermal energy is wasted. Together with the high temperature flue gas discharged in the process will take many tropical significant, sensible heat and latent heat released into the atmosphere, present in the flue gas nitrogen oxide and other substances to form a certain level of air pollution, air quality impact. Primary condensing gas boiler through the use of condensing heat exchanger from the boiler exhaust gas present in the condensed water vapor, to complete the advancement of the thermal power boiler, and can effectively reduce air pollution. In other countries, the use of condensing skills now in sophisticated stage. With the development of energy-saving and environmental protection requirements, condensing skills in our use and also have to carry out more and more prospects. In the course of condensation skills, detailed device often used to recover flue gas condensation heat and the like. 2. The heat pipe heat pipe is a highly effective skills transfer element, which is one of the most important skills in space science and technology of high-tech components. A vacuum condition inside the heat pipe, the presence of appropriate amount of liquid having a thermal conductivity in this vacuum condition inside. When the heated liquid heat pipe heat must have been terminated, the inside of the heat transfer liquid is absorbed immediately, so that a sharp rise in temperature itself, until steam is generated. When the vapor rises to the other end of the heat pipe, i.e., when the cold end, the corresponding latent heat of vaporization released out of body heat pass. In this case the effect of the steam is condensed again into liquid is liquefied, by virtue of its own gravitational force back to the heated end of the heat pipe. The heat pipe is performed through the above-described repetitive transpiration, condensation cycle to complete phase transformation latent heat of the flue gas absorption, release, and thus useful for conducting heat is completed. Heat pipe air preheater can be useful for all heating air burning, smoke decreased during the onset of heat loss, strengthen the power boiler burning hot air, effectively improve the industry used to carry out. Air heat pipe heat exchanger may be useful to complete the via flue gas heat for preheating the air, and efficient for the boiler furnace to complete the hot air supply feed. Heat pipe skills of scientific, rational use not only bring huge economic benefits to the industry to carry out and complete the decline may be useful energy, reduce pollution, play an important effect in carrying out environmental protection and national economy.

3. The system of circulating water pump system circulating pump frequency inverter skills are important skills in accordance with a detailed user heat demand, the frequency of the circulating pump motor for speed, after the completion of the circulating water system useful for conditioning. Practical use of that reduced power loss may be useful in the process of distribution pumps, power saving is to save skills. Based on hydrodynamics know, the circulating pump, the circulating water which, as a link between the two pump speed pump speed; the head, between the two pump speed was proportional to the square contact; the shaft power, the pump speed between the two was is proportional to the cube of contact. Thus, using a pump frequency of skills in the gas boiler, you can cycle through the method of slowing the pump speed to complete the pump power consumption is reduced.

Vacuum boiler is one type of hot water boiler.The vacuum boiler is mainly classified by fuel, which can be divided into electric heating vacuum boiler, oil fired vacuum boiler, gas fired vacuum boiler, coal fired vacuum boiler, etc.ZG mainly supply 2ton,3ton,10ton,20ton and 35ton vacuum boiler and all the fuel above can be used in ZG vacuum boiler.

August 21 this year, is located in Tai'an City, Shandong Province People's Government issued the "Tai'an City 2018-- 2020 coal consumption reduction alternative work" (the "Program"), "plan" put forward the goal: by 2020 the city's coal total consumption control in less than 16.85 million tons.

"Plan" indicated, coal and other industries to promote the advanced production capacity instead of backward production capacity, optimize the layout of the coal industry, shutting down and eliminate small coal-fired boilers. Upon completion of the city's 10 tons of steam per hour and cleared of all coal-fired boilers, the city and county levels, no new urban area per hour and 35 tons of steam coal-fired boilers; 65 tons of steam per hour and higher fuel coal boiler completed the transformation of energy-saving and ultra-low emissions, reduce coal pollution, speed up the heating pipe network construction to expand the scope of central heating. Actively expand the consumer market in natural gas, fuel structural adjustment, encourage the development of direct supply of natural gas to large users to promote key industrial enterprises, industrial parks to achieve direct supply of natural gas. By 2020, natural gas consumption in the proportion of energy consumption increased to about 7%.

It is reported that the city will strengthen the clean-up before 2017 and shut down illegal projects, energy regulation and elimination of backward small boilers, small thermal power production, and resolutely prevent their return to work to resume production. And optimizing the layout of the coal industry, in strict accordance with the State-owned power plant deploy clean up illegal construction, and resolutely shut down coal units do not meet behind environmental protection, energy consumption, safety and other requirements. Meanwhile, on the basis of improving industrial enterprises above coal consumption data networking direct reporting system, increase audit statistics and law enforcement, and strengthen the quality of statistical data management, improve the accuracy and timeliness of coal consumption statistics.
