coal boiler for textiles machines

Fourth, improve the degree of environmental protection

We all know that coal-fired furnace has been impermissible environmental policy, coal is a serious source of pollution not only pollutes the environment but also cause a variety of effects on the body, after making use of the boiler gas furnace, greatly reducing soot and various kinds of soot emissions can effectively improve air quality, more environmentally better protect the cleanliness of the air, but also more in line with the standards of environment protection and energy policy.

March 19, 2019, Tangshan, Hebei Province, the city government official held "2019 Tangshan depth control key industries scientific and technological achievements Matchmaking" meeting the cement industry on air pollution emissions caps mobilization discussion. According to the news conference, Tangshan City Cement companies need before the end of September this year will be dust, sulfur dioxide, nitrogen oxides are controlled to not more than 10mg / m³, 30mg / m³, 50mg / m³. Official documents will be introduced in the near future.

It is reported, as early as in September last year, Tangshan cement industry in particular has a value of air pollutants emissions of nitrogen oxides emission concentration is less than 50mg / m³ proposed.

September 3, 2018, Tangshan Municipal Government issued the "ecological environment in Tangshan depth remediation tackling month action plan", "plan" industrial enterprises in pollution control, discharge of pollutants in the cement industry to make the following requirements: single production of raw grinding material, bag filter employed; one mill kiln production process, humidification tower may be used - electric precipitator dust collection system, dust emission concentration ≤10mg / m³. Rotary kilns for cement kiln and, preferably high dust coating, conditioning tower may be used - electric precipitator, dust emission concentration ≤10mg / m3, the concentration of sulfur dioxide emissions ≤50mg / m3, nitrogen oxides emission concentration ≤ 50mg / m3.

Under our frequent introduction of environmental policies, many units use coal-fired coal boiler for textiles machiness or other fuel boilers are faced with the situation of the boiler. Provinces for the introduction of atmospheric emissions policy, boiler "coal to gas" imminent.

Personnel and to avoid faulty gas coal boiler for textiles machines gas boiler prone to some fault in the use of the process in order to avoid it fails, we have to understand some of the considerations when using. When using a gas boiler, we should always carry out its care and maintenance of local failure timely maintenance and replacement, make sure it is working properly. Circulation pump pressure constant, the current increases and the flow drops, deterioration of the thermally conductive fluid, the viscosity increased, should be replaced or regenerated. New heat transfer fluid as a result of decomposition of aqueous or excluded gases in the system, should immediately open the vent valve of the exhaust gas. When the current is lower than normal circulation pump, the circulation pump efficiency is decreased, the flow rate decline may be heating pipes plug fouling, and should be cleaned. Low temperature liquid phase heat carrier outlet of the furnace, for lack of heat, and the exhaust gas temperature exceeds 300 ℃, the main problem is the fouling, soot blowing should be. As low exhaust gas temperature, the main issue is burning, mainly lack of the wind. Although the pressure furnace, the blast volume is not open, the furnace temperature is low, combustion insufficient strength. We should focus on rear seal machine check furnace slag, dust, etc. whether closing the ash outlet is good, with or without cold air leakage into large. Before and after the filter differential pressure increases, the pump inlet pressure drops, the filter may be stuck, the opening of the bypass, disassemble and clean the filter. Grate stuck. The reason is often broken or grate grate fall loose pins; coal grate has stuck to metallic inclusions; arched grate; slag filter (Eagles iron) sink tip and the grate stuck. Processing method: reverse hand grate plate debris removal, replacement breaking grate after the start, then jammed as startup, stop the rotation of the reasons detailed inspection to resolve. The iron eagle sink, both sides can pull the fire door pull hook n. Grate stop turning, it may be too loose chain, and sprocket meshing well, or badly worn sprocket, and chain-linked bad; the adjustment screws on both sides to re-adjust the tension grate, if still does not work, you need to exchange sprocket.
