high efficiency coal boiler

As to chain grate high efficiency coal boiler, boiler chain grate deliveries solid fuels like coal and biomass pellet into boiler chamber, the fuel burning in the chamber, turn into thermal power, and produce tons of steam per hour. In technology designs, SZL series chain grate boiler has new furnace wall design, resulting in low heat loss and high thermal efficiency, which can lower boiler running costs in brick factory. Besides, SZL series boiler is composed of a main boiler frame, rear cast-iron fuel economizer, flues, auxiliary boiler, and pipeline valve instruments. Packaged structure in design, less problems in boiler installation. And it has automatic operation system, to reach clients requirements in details.

Function of oil-fired high efficiency coal boiler furnaceThe furnace of oil-fired boiler, also called combustion chamber, is the space for fuel combustion. The furnace in which the solid fuel is placed on the grate is called a layer-burning furnace, which is also called a fire-bed furnace, and the liquid, gas or powdered solid fuel is injected into the furnace burning in the fire chamber, which is called a chamber-burning furnace, or a fire-chamber furnace, which is also called a fire-chamber furnace, which is called a chamber-burning furnace, or a fire-bed furnace. The furnace in which the coal particles are lifted up by air to burn in a boiling state and suitable for burning inferior fuels is called a boiling furnace, also called a fluidized bed furnace, and a cylindrical furnace in which coal particles are rotated at a high speed by air flow and burned intensively is called a cyclone furnace. The cross section of the furnace is generally square or rectangular. The fuel burns in the furnace to form flame and high-temperature flue gas, Therefore, the furnace wall around the furnace is composed of high temperature resistant materials and thermal insulation materials. Water-cooled wall tubes are often installed on the inner surface of the furnace wall, which not only protects the furnace wall from burnout, but also absorbs a large amount of flame and high-temperature flue gas in the design of the furnace, which needs to take fully into account the characteristics of the fuel used. Each boiler should burn the original fuel as far as possible. The economy and reliability of boiler operation may be reduced when the fuel with different characteristics is used.

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.

1, compared to the traditional coal-fired high efficiency coal boiler, gas boiler higher cost low nitrogen

Conventional coal-fired boilers is generally filled manually directly into the coal combustion furnace, this method results in very large combustion sulfide, soot and other harmful substances discharged into the atmosphere pollution index high; but also need to manually plus fuel, time-consuming and labor-intensive, more harm than good.
