composite type of an exhaust gas boiler

ZBG export to more than 17 countries such as Thailand, Indonesia, Pakistan and so on, products are oil fired composite type of an exhaust boiler and gas fired boiler.

Yangzhou City in Jiangsu Province, the municipal government issued a notice of 2019 annual remediation tasks composite type of an exhaust boiler, with the text published a list of boiler regulation, as follows.

3, the nitrogen gas boiler oxide (NOx) emission limit is not higher than 50 mg / m transformation, in accordance with other indicators of "boiler air emission standards" in the gas-fired boiler particularly performed emission limits.

(1) prohibits blended with other fuels such as coal, bags and other supporting efficient dust removal facilities, and effectively discharge standards. Emission standards in accordance with "boiler air emission standards" in coal-fired boilers particularly performed emission limits.

Full implementation of the above steam 2,65 t / h coal-fired boiler transformation ultra-low emission, soot, sulfur dioxide, nitrogen oxides, respectively, 10 mg / m, 35 mg / m, 50 mg / cubic meter.

3, disable all kinds of close small coal-fired facilities (tea boiler and furnace operating coal-fired stove, rural production, aquaculture and other coal-fired facilities), switching to natural gas, electricity, solar and other clean energy. In remote rural areas, could be replaced by forming biomass as a fuel, but must use a professional boiler, supporting efficient dust removal facilities, to ensure that pollutant discharge standards, emissions standards refer to "boiler air pollutant emission standards" in particular coal-fired boiler emission limits carried out.

4, a low nitrogen gas boiler and treatment for the transformation, the installation of low NOx combustion by the low NOx combustion mode, etc., to ensure that the nitrogen oxide emission limit is not higher than 50 mg / m. Other indicators according to "boiler air emission standards" in the gas-fired boiler particularly performed emission limits.

5, forming a comprehensive remediation biomass fuel boilers, biomass fired boiler clean-up does not meet the special requirements of the boiler, not supporting a biomass fired boiler emissions and efficient dust removal facilities of non-compliance. To meet the special requirements of the boiler and supporting efficient dust removal facilities, the establishment of accounting and retain more than one year, emission standards refer to "boiler air pollutant emission standards" emission limits in particular the implementation of coal-fired boilers. More than 10 tons of steam installation of gas-line monitoring instruments, and networking with the environmental protection department. Located in the city built-up area forming ultra-low emission biomass boilers implement reform.

6, bulk coal sales within the city limits are all clear according to the law, the use of bulk coal user implementation of the "coal to electricity" for street vendors and other "coal to gas" campaign, a pin number management. At the same time, prohibiting the establishment of long-term supervision mechanism bulk coal, non-bulk coal inflows.

How to maintain the composite type of an exhaust boiler shutdown? After boiler shutdown cooling, heating surface must be thoroughly cleaned of fouling and ash grate the upper, the lower portion of the furnace. Then to maintain a certain degree of natural ventilation flue. In general, in order desiccant moisture should be placed in the furnace, flue. The quicklime as a drying agent, within the furnace or flue gas per cubic meter should be placed generally about 3kg. After placing all the ventilation should be tightly closed doors. After the change of lime powder to be replaced. Low-lying position as boiler room, ground during shutdown severe flood tide, often approach should be used and placed a small fire to dry desiccant combination. How to care? If the boiler shutdown a long time, the boiler shutdown after complete removal of soot coated with an anti-corrosion red lead paint in oil or other metal surface furnace. As internal corrosion Maintenance shutdown of the boiler body, under normal circumstances, can be used wet shutdown maintenance is not more than one month, one month electrically operated steam boiler should be taken to dry more maintenance. To note the following problems when a dry maintenance: desiccant boiler not in direct contact with the metal surface, may be mounted in a container such as the iron plate after the desiccant is placed, and a hole for shutting the other hand hole cover.

How many calories Horizontal one ton steam composite type of an exhaust boiler needs? 1 ton steam boiler, require 600,000 calories, biomass is the most economical fuel. 1 t of steam boilers, 600,000 calories needed, is converted into fuels: diesel 58kg / hour, i.e. cost of diesel and 466 / hour; biomass particles 150kg / hour, the cost of 165 / hour. 697 electrical degrees / hour, i.e. cost of electricity 697 / hour; gas 75m3 / hour, i.e. cost of natural gas 375 / hour; 120kg of coal / hour, i.e. cost of coal is about $ 120. As can be seen from the above, coal and biomass particles are the most economical. Wherein the combustion of coal is difficult to control, and the actual consumption costs considerably biomass particles. However, polluting coal boiler is very large, and the biomass boiler is both economical, and environmentally friendly. Accordingly, we can see that biomass pellet boiler is the best future direction of development of the industry boiler, the boiler will also become the industry mainstream.
