What is the principle of the boiler? No matter how much the tonnage, the boiler works basically the same. Role of the boiler fuel chemical energy is converted into thermal energy, heating and heat inside the pot with water to become superheated steam having a mass and a sufficient amount (steam temperature, steam pressure) of the steam turbine for use. Now the power plant boiler capacity, high parameters, technical complexity, high levels of mechanization and automation, the main fuel is coal, and coal prior to combustion of pulverized coal first made, and then into the boiler combustion heat release in the furnace. Broadly speaking, the work process is the main boiler fuel combustion, heat transfer, vaporization and heating of the water with the superheated steam and the like. The entire boiler boiler composed of two parts and auxiliary equipment. Boiler: boiler body is the main part of the boiler equipment, is composed of two parts, "pot" and "furnace" composition. "Pot" is the soda system which main task is to attract the heat receiving fuel discharged, the water is heated, evaporated and finally becomes superheated steam having certain parameters. It consists economizer, the drum, the downcomer, the header, water wall, superheater and reheater connecting pipes and other equipment and valves. 1) economizer. Vertically positioned rear of the boiler flue, the use of flue gas waste heat boiler feed water, reducing the exhaust gas temperature, increase boiler efficiency, fuel economy (2) drum. At the top of the boiler, it is a cylindrical pressure vessel, which is under water, the upper portion of the steam is that it accepts the economizer runoff, while the downcomer composed header, Wall water circulation circuit. Wall water absorbs heat generated in the soda mixture was collected in the drum, conveyed by the saturated steam to the superheater steam-water separator (3) downcomer. Water supply pipe water wall, the effect of which is introduced into the water in the steam drum to the lower header redistribution respective waterwall tubes. Dispersion in small diameter and the large diameter downcomers Downcomer two kinds. Small diameter tubular small diameter drops, the water cycle of negative (4) waterwall lower header. The main role of the header is a mass pooled or working fluid through the header to the header redistributed through other conduits. A water wall is thicker lower header tube closed at both ends, its role is connected to the downcomer and the water-cooled wall, so as to function together, mixing, redistribution effect working medium (5) water wall. At the furnace around its main task is to absorb radiant heat of the oven, to evaporate water, which is the main heating surface modern boilers, while protecting the furnace wall (6) superheater. Its role is to drum saturated steam into superheated steam on heating (7) having a predetermined temperature reheater. Its role is done in the steam turbine power section is heated up again, and then continue to work in the steam turbine. "Furnace" is the combustion system, its task is to make the fuel burn in a good furnace, heat. It consists of the furnace, the burner, ignition means, air preheater, the smoke duct and the furnace wall, frame and other components. (1) furnace. It is transferred from the furnace wall and into the water wall for fuel combustion, the fuel combustion in suspension, the release of large amounts of heat within the space. (2) burners. Located on the furnace walls or corners, its role is the fuel and air injected into the furnace at a constant speed, so that it can be well mixed in a furnace in order to ensure timely ignition and rapid and complete fuel combustion. DC sub-burner and swirl burner two basic types. (3) air preheater. Located in the boiler backpass, whose role is to use waste heat of flue gas to heat the fuel required for the combustion air, exhaust gas temperature can be further reduced not only, but also for strengthening the furnace combustion, improve the economy of combustion, pulverized coal drying and conveying is advantageous of. Boiler efficiency can be increased by 2%. And rotary two kinds of charge. (4) smoke duct. From the furnace wall is a pipe, the pipe heating surface and the portion of the tube wall and other components of the package, for guiding the flow of flue gas through the heat exchanger and the respective heating surface, and is divided into horizontal flue backpass. Auxiliary ventilation apparatus comprises auxiliary equipment (delivery, induced draft fan), a fuel transportation equipment, milling system, in addition to ash and dust removal equipment, desulfurization equipment.
The third reason is that the amount of nitrogen oxide released during operation is very small. Most heating equipment such as ordinary boilers need to use coal materials as raw materials when they are in operation. Materials such as coal generally release a large amount of hazardous air-quality substances when burned. The condensing boiler uses the steam produced by natural gas combustion as the raw material when it is in operation, so the nitrogen oxide content released during the operation is much lower than the prescribed standard. The analysis of the reason for the year-by-year increase in the sales of condensing boilers has come to an end for the time being.
At any time, domestic more and more attention to environmental protection, coal-fired paper industry 2 ton coal fired steam boiler for sale suffered heavy damage. Relatively speaking, gas-fired steam boiler is favored by many users. In recent years, the state has also vigorously promoted the use of gas-fired boilers. What are the benefits of a coal-fired steam boiler? Let's discuss it with you today. Gas-fired steam boilers and coal-fired steam boilers occupy half of the market, showing a trend of court resistance, but in the long run, gas-fired steam boilers will obviously become the only dominant market. No, please look! 1. Procurement cost: it is clear that gas-fired boilers are well ahead of ignition in terms of technology and ancillary equipment The coal boiler is equipped with a special gas burner. Take 1 ton steam boiler as an example, gas-fired boiler is about 30% higher than coal-fired boiler. 2. Construction cost: this cost mainly comes from boiler room. Because of the coal-fired steam boiler supporting equipment more, boiler room construction should invest more funds. The auxiliary equipment of gas-fired boiler has few auxiliary equipment, automatic control operation, automatic alarm and automatic protection function, which not only saves the cost of building, but also is safe and reliable. After connecting the natural gas pipeline, the burner will automatically supply gas, which can effectively save staff costs. Coal-fired boilers also have to pay some of their employees' salaries because they need to participate in the coal program . 3. Fuel costs: you can see this clearly by looking at the actual specific fuel prices at each location. The fact is that the amount of coal burned per hour is much higher than the amount of gas. 4. Environmental costs: with the need to protect the environment, the audit of coal-fired boilers is becoming more and more stringent. Gas-fired steam boilers are more and more widely used due to economic operation, environmental protection and energy conservation, as well as government policies.
In response to national environmental policy development, improve the quality of people's living environment of the area, Guangdong Province, actively promote the boiler "coal to gas" action. Currently, Dongguan City, "from coal to gas," the work has entered a crucial stage, nearly two months, the city government, city atmosphere Office, the Municipal Development and Reform Bureau has organized a thorough inspection teams to supervise the Towns "coal to gas" work . Atmospheric do inspection personnel Lurui Quan admits: "From the inspection situation, many companies on the 'coal to gas' is still in the wait and see attitude, worried about the safety and cost issues."
As of March 25, Dongguan City, 26 companies of 37 coal-fired boilers (except coal-fired captive power plant boilers), it has been out of the 17 units, 14 companies were using natural gas. In addition, 12 companies of 20 coal-fired boilers, is expected to complete phase transformation within this year.
It is expected that in the near future, all industrial boilers transform the use of clean energy, Dongguan sky will be bluer.
