SZL series boiler is a biomass boiler widely sold at home and abroad. CBM provides a 10 ton SZL environmental coal fired 1 ton steam boiler for sale for a company in Tanzania. The SZL series boiler adopts advanced technologies and has many advantages. The 10 ton szl biomass steam boiler could burn biomass fuel, bituminous coal and others.
The whole structure of normal pressure BoilerThe whole structure of atmospheric pressure boiler consists of boiler body and auxiliary equipment. The main components of boiler, such as furnace, boiler barrel, burner, water-cooled wall superheater, economizer, air preheater, frame and furnace wall, constitute the core part of steam production, which is called boiler body. The two main components of the boiler body are the furnace and the drum. The furnace, also known as the combustion chamber, is the space for fuel combustion. The furnace in which the solid fuel is placed on the grate is called a layer furnace, also known as a bed furnace; the liquid, gas or powdered solid fuel is injected into the furnace burning in the fire chamber, which is called a chamber furnace, or a fire chamber furnace; the air turns coal particles into the furnace, which is called a chamber furnace, or a fire chamber furnace; the air turns the coal particles into a chamber furnace, also known as a fire chamber furnace. It is called boiling furnace, also called fluidization bed furnace, in which the furnace with boiling state and suitable for burning inferior fuel is called boiling furnace, and the cylindrical furnace which uses air flow to make coal particles rotate at high speed and burns intensively is called whirlwind furnace. The furnace design 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.
Boiler startup startup boiler combustion adjustment method should pay attention to the flame monitoring, combustion and make adjustments as follows: (1) correct the ignition. Adequate ventilation furnace before ignition, the ignition first investment ignition device (or torch), then turn the gun. (2) diagonally administered fire mouth, pay attention to timely switch, the flash point was observed nozzle suitable fire, flame sought uniformly distributed in the furnace. (3) to adjust the lead note, air volume, furnace pressure should not be too large. (4) in particular to monitor exhaust gas temperature when combustion instability, the occurrence of the back pass to prevent the secondary combustion. (5) to maximize the temperature of primary air, secondary air is fed reasonable depending on the fuel. Adjusting the temperature difference between both sides of the cigarette. Do pulverizing system-OFF stable (6) operation. Stoker coal under stable powder machine speed and stability. Coal with wind stability and oxygen stable. Steam temperature, steam pressure increase stability and load stability liter.
Dezhou City, Shandong Province issued - an important part of "Dezhou 2018 2020 coal consumption reduction alternative work" (the "Program"), the Yajian coal consumption as an ecological civilization construction and environmental protection work, and resolutely fight pollution prevention tough fight. "Plan" put forward, as of 2020, total coal consumption Dezhou control in less than 18.5 million tons, clean heating rate of 70%.
According to "program" requirements, Dezhou vigorously for shutting down the environmental, energy, security and other 300,000 kilowatts of coal-fired units of non-compliance, especially running at least 20 years of pure condensing units and over 25 years of condensate pumping thermoelectric unit. At the same time shutting down out of small coal-fired boilers to reduce coal pollution. Upon completion of the city's 10 steam tons / hour and coal-fired boilers are all clear on the key areas in national, provincial and determined basically eliminated 35 tons of steam / h coal-fired boilers, 65 tons of steam / hour or more coal-fired boilers completed energy efficiency and ultra-low emissions transformation.
Dezhou will also expand the scope of central heating, promoting clean urban and heating, 2020, the Center City District (Germany City, Texas Economic Development Zone, the Canal Economic Development Zone) central heating area of 45 million square meters, the other 10 counties (cities, districts) central heating area of 41 million square meters, the implementation of central heating pilot projects in rural areas where conditions permit. For areas not covered by central heating, according to the resources in the area of heating conditions, combined with infrastructure construction, promote the substitution of gas for coal to other electricity-generation clean energy alternatives such as coal and biomass. As of 2020, Dezhou city's average clean heating rate of 70%. Among them, the city basically clean heating comprehensive coverage, average clean heating in rural areas reached about 55%.
In addition, Dezhou will continue to increase the proportion of natural gas consumption, substitution of coal consumption, encourage the development of direct supply of natural gas to large users to promote key industrial enterprises, industrial parks to achieve direct supply of natural gas. By 2020, increase the proportion of natural gas consumption in energy consumption to about 7%.
