Industrial Steam Low Pressure Chain Grate 1 Ton Coal Boiler

What is the principle of the industrial steam low pressure chain grate 1 ton coal 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.

It is understood that around prevention and control of air pollution, ecological Environmental Protection Office of Shaanxi Province has formulated the "Boiler Air Pollutants Emission Standards" ( "Standards"), amended the "off key industries in the region of atmospheric pollutant emission limits." In the future, biomass, alcohol fuel industrial steam low pressure chain grate 1 ton coal boiler emissions also be included in "Standards".

"Standard" is to integrate and improve the local air emissions standards boilers. "Standard" for the scope of the province, covering coal, gas, oil, various types of fuel such as biomass; using alcohol fuel (e.g., methanol, ethanol, dimethyl ether, etc.), gas-fired boiler with reference to the implementation of emission limits.

After calculation, coal-fired thermal power boilers in Shaanxi Province implementation of the new standards, particulate matter, sulfur dioxide, nitrogen oxide emissions respectively about 0.67 tons 15,200 tons, 1.26 tons, down 27%, 40%, 21%; Burning after transformation of coal boiler, particulate matter, sulfur dioxide, nitrogen oxide emissions can be about 01,400 tons, 1.42 tons 14,100 tons.

With the haze pollution reduction work to promote strong, Shaanxi Province coal-fired generating units and 20 steam tons / hour or more coal-fired boiler to carry out the transformation of ultra-low emissions, will gradually iron and steel, cement and other industries to carry over non-electric low-emission transformation, the original standard has been overtaken by change of environmental situation. Additionally, the Guanzhong area of ​​glass, ceramics, bricks, gold and other industry, there are a certain number of kiln, its environmental requirements leniency.

The revision of the "off key industries in the region air pollutant emission standards", the abolition of the thermal power industry, coal-fired boiler emission limit requirements, these two sectors rose to individual standards province-wide.

It also increases the coke nitrogen oxide emission limits Chemical Industries, gold industry, glass and glass products, ceramic industry emission limits, increasing the concentration of tile industries and atmospheric pollutants conversion approach.

The new standards are expected coke chemical industry NOx emissions will decrease 70%, the sintering process the steel industry, the particulate matter, SO2, NOx emissions decreased by 50%, 72% and 67%, respectively.

Steam Boiler with different fuels can be divided into biomass industrial steam low pressure chain grate 1 ton coal boiler, coal fired boiler, gas fired boiler, oil fired boiler, etc.

The coal fired steam industrial steam low pressure chain grate 1 ton coal boiler consists of two large boiler drum out of factory , up major possession including boiler body , upper steel frame and furnace wall ,lower bulk including coal bucket ,chain grate ,lower furnace wall, and internal ventilation tube. Fuel: Bituminous Coal, dry-burning coal, hard coal, ligneous coal, etc.

1.Combustion and both sides of the furnace chamber adopt membrane water-cooling wall structure. With this kind of structure, the boiler has a high heat transmission coefficient, low heat loss, good air tightness, no distortion for furnace wall and no ash leakage.

2.Furnace front and rear water wall tube extend down to the upper portion of the grate and form the front and back arch, which extends the span of arch.

3. Inverted “α” arch furnace technology makes the front arch high and short, rear arch low and long. This structure increases the burning time of the flue gas in the furnace so as to improve the combustion efficiency. Besides, the streamline shape of back arch can throw the left carbon grains from the back furnace grate into the front so that the coal is easier to get ignited. Finally, many types of coal can be applied in the boiler.

4.The length of the front and back shaft is longer than the other domestic ones, which prolongs the time of fuel combustion in the furnace and lower the carbon content in the furnace slag. Thus, the overload ability of the boiler is strengthened with the increased effect area of furnace grate.
