Szl Series Assembled Coal Fired Hot Water Boiler

Szl Series Assembled Coal Fired Hot Water Boiler

Greater than 65t / h industrial boiler of what air pollutant emission standards should be executed? A: The State Environmental Protection Administration, Central Division-standard [1993] No. 012 document pointed out that the emergence of a small number of parameters currently higher than GB1921-80 "industrial steam boiler parameters Series" and GB3166-82 "szl series assembled coal fired hot water boiler parameters Series" layer burning, stoker boiler, regardless of its use Zanan GB1327-91 execution. Therefore> 65t / h or more (except coal, circulating fluidized bed, and fuel, gas fired boilers) industrial boilers should be performed "boiler air pollutant emission standards."

Environmentally friendly and efficient hot water furnaces

The working principle of hot water boiler is very simple, which depends on the heat energy of fuel combustion to achieve the function of heating water, it is a kind of simple heat energy boiler. Hot water boiler is one kind of boiler, mainly because its medium is hot water. There are many kinds of hot water boilers, which can be divided into point hot water boilers, oil hot water boilers, and some more environmentally friendly gas and coal fired hot water boilers according to the fuel used.

Recently, Dezhou City, Shandong Province, has released the main points of pollution prevention and control in 2019, set specific targets and implement measures to control emissions of persistent pollutants SO2, NO2, to reduce the number of aspects such as severe pollution days.

1, continued to promote the total coal consumption control. Strictly implement the coal consumption reduction, equivalent alternative policy requirements. Continue to implement the monitoring and early warning mechanism to control the total amount of coal, coal consumption for the counties (cities, districts) were scheduled monthly, quarterly analysis, forecasting and early warning and timely release. Refined coal decomposition control mission objectives to ensure the completion of the annual total coal consumption control tasks.

2, strengthen renewable energy development and utilization. Actively promote wind, solar, biomass, geothermal and other renewable energy sources, promotion of power generation, industrial and residential heating and other heating applications. Achieve renewable energy consumption accounted for the proportion of primary energy consumption of more than 15%.

3, continue to promote the management of coal-fired boilers. The existing 35 tons of steam coal-fired boilers, according to ranking policy before the end of 2019 included in the phase-out plan. The inclusion of out of range, to ensure that out of the task before the end of 2020.

4, the implementation of low NOx combustion gas boiler reconstruction. To 2020 basically completed the transformation of low-NOx combustion as the goal, listing the existing inventory ledger gas boiler, to determine the transformation of an object, complete renovation in 2019 total about 50%. After transformation of NOx emission in principle higher than 50mg / m3. Achieve a stable concentration of nitrogen oxide emissions rebuilt 30mg / m3 or less (that is, ultra-low NOx combustion requirements) can be appropriate priority in provincial subsidies make up ecological civilization prize funds.

5, continue to promote clean coal. Strengthen clean coal production, supply, construction and distribution system, and continue to improve the implementation of the subsidy policy, to ensure the timely distribution in place to protect the people warm winter. Bulk coal market to strengthen the comprehensive improvement of law enforcement, the implementation of three coal detection mechanism to prevent inflow of low-quality bulk coal, clean coal to ensure quality standards. 2019, on the basis of full coverage in clean coal, continue to promote clean coal.

6, strengthen high-pollution fuel combustion zone ban construction. Combustion zone ban, a ban on new or expanded high-polluting fuel burning facilities have been built to the deadline to switch to clean energy. Investigate and punish illegal construction, expansion and high-polluting fuel facilities are not completed within the prescribed period rectification behavior. Ban on burning coal for a total ban on the circulation area.

7, continue to promote clean heating transformation. To proceed from reality, should the electric power, gas should the gas, the coal should be coal, should be hot is hot, warm winter to ensure the safety of the masses. Accelerate the pace of production, supply and storage of natural gas marketing system construction and gas storage facilities, improve air support capabilities. To develop multi-gas source, priority for clean heating, ensure safe and stable gas. Strengthen heating, gas facilities construction, expanding the central heating, gas, geothermal heating coverage. Accelerate the clean heating renovation project, before November 15, 2019 to complete the annual task of transformation goals. Complete power-generation coal, gas and other clean coal generation of heating transformation of the region, a total ban on bulk coal sales, to prohibit the sale and hoarding bulk coal, bulk coal to prevent the re-burning.

Works chemical plant boilers is what works what chemical plant boiler is? Energy conversion device is a boiler, a boiler input energy comprises a chemical energy, electrical energy, thermal energy of the flue gas temperature and the like. After conversion of the boiler, steam, water or high-temperature organic heat carrier having a certain thermal energy to the boiler outlet. Mainly used in thermal power plants, ships, locomotives, industrial and mining enterprises. The main principle is a use of the chemical energy released by combustion of boiler fuel or industrial waste heat transferred to the water container, the water reaches the desired temperature or pressure of the steam heating apparatus. Boilers and boiler furnace two parts at the same time, water enters the boiler, the boiler heating surface in the steam - water system will absorb heat transferred to the water, so that by the hot water reaches a certain temperature and pressure to produce hot water or steam or, is introduced into the application. cation. In the combustion apparatus part, sustained release heat of fuel combustion, high temperature flue gas produced by combustion heat propagation, to transfer heat to the boiler heating surface, the temperature itself is gradually reduced and finally discharged through a chimney. Works chemical plant boilers is what - Classification steam boiler: First, the fuel can be divided into: 1, coal-fired boilers, 2, oil-fired boiler, 3, gas boiler, 4 electric boiler, boiler and nuclear 5, 6, waste heat boiler, etc., most top four, the most common, the lowest operating costs of coal-fired boilers, but a large area, serious environmental pollution, the requirements of operators, gas boilers high degree of automation, operating costs than coal, accounting small land area, requiring fewer operators, I did not use electric boiler, but running costs should be the highest, but the small boiler footprint, environmental protection is the best, the other boiler is not introduced, because I do not understand you the meaning of. two. The heat transfer mode can be divided into water-tube boilers, the thermocouple tube boiler, water tube boilers and fire tube boiler. Usually gas fuel boiler fire tube boiler, typical Type: series WNS (horizontal combustion boiler combustion chamber), this boiler characteristics: simple structure, the rated capacity of the evaporator is generally small (typically 10 tons or less, have a greater , but generally not more than 35 tonnes), starting the furnace pressure faster, lower quality requirements boiler; coal-fired boilers typically water boiler. Tube boiler, water tube boiler high thermal efficiency, but the complex structure of the boiler a higher quality requirements.
