Right after the shutdown shutdown and maintenance methods steam boiler for food industry: I believe it is not strange for large steam boiler, we know when its not in use in order to reduce waste of resources, it needs to be shutdown. But it's the right way to shutdown and how much you know about it? After the shutdown maintenance methods and how is it? Here's a small series and learn together about it!
Environmentally friendly and high-efficiency water heaters: Hot water boiler for food industry works is very simple, which is by fuel combustion heat to achieve the function of heating water, is a very simple heat boiler. Hot water boiler is a boiler, mainly because of its medium is hot water. There are many hot water boiler classification, according to which fuel can be divided into, some hot water boilers, hot water boiler fuel, as well as some of the more environmentally friendly gas and coal-fired hot water boiler.
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.
Superheater and reheater are arranged in claim 1, low-pressure boiler for food industry endothermic characteristics: a low pressure boiler, a large latent heat of vaporization. Evaporation amount of heat, less heat superheater heating surface arrangement: In addition to the water-cooled wall, before the superheaters, the convective arrangement requires a certain amount of evaporation tubes. 2, the heat absorption characteristics of the boiler pressure: Radiative heat and heat of vaporization rather, no additional evaporator heating surface disposed; heating surface arrangement: arranged only after the superheater tube furnace Slag outlet. 3, high-pressure boiler endothermic characteristics: small vaporization latent heat, less heat required for evaporation, preheating and superheating heat amount of heat; heating surface arrangement: In addition to a convection superheater, also need superheater portion disposed in the furnace, i.e., using radiation superheaters, it may be part of the radiation as a water wall economizer.
