solid fuel steam output boilers
In early 2019, Xingtai City, Hebei Province, air pollution control for industrial enterprises, to develop the relevant regulations. Mainly for the protection and improvement of the atmospheric environment, prevention of air pollution and protect public health, promote the construction of ecological civilization, and promote the development of sustainable economic and social development goals.
First, according to the national industrial policy, Hebei Province, strict control of new construction, renovation, expansion of iron and steel, cement, plate glass, synthetic chemical pharmaceuticals, non-ferrous metal smelting, building ceramics, chemicals and other industrial projects.
Iron and steel, cement, plate glass, synthetic chemical pharmaceuticals, non-ferrous metal smelting, building ceramics, chemicals and other key industries cleaner production audits in accordance with law, the use of advanced clean production technologies, processes and equipment.
Urban area, high above emissions in key industries around the ecological red line in the control area, high-pollution projects should be gradual relocation, renovation or restructuring, exit.
Air pollution insurance companies encourage heavy environmental pollution liability insurance.
Second, the city and county (city, district) people's government may take their overall economic efficiency sorting, etc., specific measures for serious overcapacity in the industry, the atmosphere of heavily polluting enterprises, the differential credit, the difference is the price of water, different gas prices, punitive tariffs, etc. .
Third, the industrial concentration area should develop cogeneration and district heating, heat unified solution. In addition to centralized district heating and combined heat and power, waste incineration and biomass power generation project, the city's ban on new or expanded high-polluting fuel for power plants, ban high-pollution fuel combustion zone ban on new construction, expansion-owned high-polluting fuel boiler heat supporting units supply station.
Boiler for industrial production should reach atmospheric pollutant emission standards set by the State and the boiler Hebei and marked fuel requirements and atmospheric pollutant emission control targets.
Fourth, industrial enterprises store coal, cement, lime, sand and other materials easy to produce pollution should take sealed enclosure, cover, cleaning, watering and other measures to prevent dust pollution.
Fifth, iron and steel, petroleum, nonferrous metals, electric power, coke, construction materials, metallurgy, chemical and other industrial enterprises in the production process emissions of dust, nitrogen oxides and sulfides, shall adopt cleaner production processes, supporting the construction dust removal, desulfurization, denitration apparatus, or take other measures to control the emission of air pollutants like transformation.
Gas solid fuel steam output boilers, environmental protection and environmental protection the new force of the word have been common, but it can really achieve environmental protection of the people are few. Now with the emerging social technology products, a large number of industrial waste arising therefrom, for causing serious environmental harm, especially some require combustion boiler manufacturers, the smoke discharge of sewage is very serious. Whether smog or industrial waste water for hazardous environments are very large, so in order to be able to do a better job of environmental protection, the government called on people in the use of the boiler must choose to use gas-fired boiler. Use the boiler is that many companies have, and the reason is because the boiler to provide heat energy in industrial production needs of the people, but the general boiler during use due to the problem of fuel leads to a lot of smoke and waste water, such an action would It will cause great pollution. So if we want to use the words of the boiler must choose to use gas-fired boilers, the reason is because the more environmentally friendly gas-fired boiler. Boilers for environmental pollution caused mainly due to the fuel, but if you are using a combustion boiler, then it is not such a situation. Because the fuel gas-fired boiler is mainly natural gas, such an action would not be so much waste material present in the combustion process, naturally, will not appear so much smoke to affect the surrounding environment. Government requires people to use gas-fired boiler is to reduce environmental pollution, as compared to the general terms of better environmental protection boiler gas boiler work to do, so we need to use gas-fired boilers to environmental protection work in helping us produce at the same time.
1.4MW how much gas heating solid fuel steam output boilers heating area: about heating area this one has been the focus of discussion, the 1.4MW gas heating boiler heating area how to calculate it Here we learn next to you on the exchange of gas boiler heating area by the main basis? the area belongs to which type, common main types, hotel, housing complex, office buildings and other buildings area, workshop, warehouse, storage rooms and other hospital areas of these projects, underground parking, large-scale transfer of library materials, these are the common areas such as a large grain reserve, and so many more not one by one example.
Under different loads, thermal efficiency of the solid fuel steam output boilers whether there will be major changes?Each boiler has an economic load range, generally about 75% to 100% of rated load of the boiler, than this load, the efficiency is decreased below this load, the efficiency also decreased; for each boiler furnace and smoke channel capacity is fixed, when the rated load is exceeded, causes the fuel in the furnace residence time is too short, not enough time to be taken out of the combustion furnace, resulting in increased heat loss chemically incomplete; because excessive smoke, smoke flow and flue gas temperature of greater than normal, causing a large loss of the flue gas, reducing its efficiency. In the low-load operation, since the furnace temperature drops more, burning disturbance weakened, incomplete combustion heat loss increases, boiler efficiency will be reduced.
