Pollution caused by paper mill chain grate boiler firing systems

The paper industry is one of the industries with high energy consumption, high material consumption and serious environmental pollution. The energy equipment used in paper mills is usually a steam boiler. Contaminants generated by boilers can also cause many hazards.

It is understood that, recently, the ecological environment Department of Henan Province issued the "Henan electricity in 2019 non-standard governance program industry" and six special programs, mainly to further promote the campaign of air pollution control, to ensure that the province's ambient air quality continues to improve. Meanwhile, the "plan" also made clear this year Henan Province industrial air pollution control in key tasks.

The province meet the conditions of steel, coke, cement, carbon (including graphite), flat glass (including electronic glass), aluminum and other six major industries and enterprises, the requirements before the end of this year to complete the mentioned standard treatment, the required limits for reducing pollutant emissions. Carry closed down or banned brick kiln, lime kiln, tunnel kiln, firing kiln and a variety of smelting furnace, roaster and so on nine categories of Kiln, upgrading, restructuring and integration work. Before the end of October this year, all kinds of industrial furnaces to achieve discharge standards.

Before the end of June this year, the province's petrochemical, oil refining, industrial coating, packaging, printing, chemicals, pharmaceuticals and other industrial enterprises, the full completion of volatile organic compounds pollution control; before the end of August, the province's petrochemical, oil refining companies to complete volatile organic compounds depth governance and leak detection and repair of governance; before the end of December, the provincial cities of built-up areas phasing out the open dry-cleaning machine.

Before the end of October this year, in addition to undertaking tasks and will not have the alternative livelihood conditions, the province completed 35 steam tons / h coal-fired boilers and the removal or clean energy transformation, provincial cities and county (city) district built 4 tons of steam and above gas-fired boiler, fuel (including alcohol-based fuel) boiler low nitrogen transformation complete, the provincial municipality to build a biomass boiler area (including biomass power plants) completed the first ultra-low emissions transformation. Before the end of June this year, the completion of the provincial cities to build coal-fired facilities Chaigai all industrial areas.

The reason for the high exhaust gas temperature following points 1, leakage is serious leakage refers to the furnace, flue, etc. due to poor quality welding or other causes leakage phenomenon is an important reason for the high temperature exhaust gas chain grate boiler firing system. Mainly refers to the furnace roof seal leakage, see the crater, and the bottom seal Manhole leakage at the sink; chimney flue leakage refers to leakage when the ambient air in the negative pressure operating chamber wall and at the flue imprecise, especially in the furnace end leakage greatest impact. Leakage will make the exhaust volume increases, exhaust heat loss will also increase. 2, hot air factor is too large the air ratio has an important influence on the boiler thermal efficiency and combustion conditions. When the air ratio is too large, the amount of the boiler flue gas emissions will increase, so that the boiler flue gas heat loss increases, induced draft fan, blower power consumption will increase, resulting in reduction in thermal efficiency. Choose the right air ratio, it will reduce the energy losses, get a higher thermal efficiency of the boiler, and the safe operation of the boiler. When the load changes, can be adjusted into the furnace fuel and air quantity, the corresponding changes in the combustion conditions. 3, more fuel moisture content on water in fuel combustion is the main cause burning fire difficult, and reduce the temperature of the combustion zone, the fuel may not fully burn. When the fuel water every 5% increase, due to the thermal efficiency of the boiler heat losses will drop about 0.5%. 4, heating surface scaling, fouling, boiler slag when the heating surface due to poor water quality when the water content of the fuel or the like caused by excessive scaling or corrosive conditions, will produce heating surface scaling, fouling, slag and other undesirable phenomena, will effect of heating surface and heat transfer to the flue gas, the flue gas can not be cooled in a timely manner, resulting in exhaust gas temperature.
