biomass fired grate wood pellet boiler for hotel
2. Circulating fluidized bed (CFB)
Circulating fluidized bed combustion(CFBC) Advantages :
1. Fluidized bed can burn a variety of fuels-coal as well other non-conventional fuels like biomass, petro-coke, coal cleaning waste and wood. This bed contains only around 5 percent coal or fuel. The rest of the bed is primarily an inert material such as ash or sand. Fluidized bed boilers are capable of burning a wide range of fuels cleanly, including biomass fuels such as wood waste.
2. The Temperature in FBC is around 800-900°C compared with 1300-1500°C in pulverized coal combustion (PCC). Low Temperature helps minimize the production of NOx (nitrogen oxides). With the addition of a sorbent into the bed (mostly limestone), much of the so2 formed can be captured. The other advantages of FBC are Compactness Ability to burn low calorific values (as low as 1,800 kcal/kg) Production of ash which is less erosive. Moreover, in FBC, oil support is needed for 20-30 percent of the load versus 40-60 percent in PCC. FBC based plants also have lower capital costs compared to PCC based plants. The capital costs could be 8-15 percent lower.
Biomass fired biomass fired grate wood pellet boiler for hotel designs include coal-fired boilers with chain grate stokers, wood fired boilers with fixed grates, as well as custom-designed waste heat boilers. All biomass fired boilers are designed and manufactured to latest Standard, such as AMSE. In ZG, Biomass fired steam boiler for sale is devided into saturated steam boiler and overheat steam boiler and meet the needs in seperated.This series boiler belong to chain grate boilers, designed for blowdown on surface and the quality of steam is pretty good. Biomass fired oiler main body and grate adopt large parts for ex-factory, short installation time and low charge for installation. biomass fired boiler capacity of 4-35T / H (2.8-29MW).
It features gas biomass fired grate wood pellet boiler for hotel gas boiler is a very environmentally friendly boiler, it can be widely used in various fields, and very loved by the people. The main fuel is natural gas boiler, does not produce harmful gases when burned, and the compact structure of the boiler, sealing, and natural gas can burn more fully. Also known as gas-fired boiler gas, or natural gas is a combustible liquid fuel. Heat carrier. Forced liquid circulation by the circulation pump. After the delivery of energy to the heating equipment. Roll- type DC special industrial furnace reheated. Widely used The petrochemicals in textile dyeing. plastic, rubber, food processing. wood processing. asphalt heating. carton production. dehydrated vegetables. lacquer. die casting sand drying and the like, can also be used ≤350oC baking, steaming, shaping, the molten ,dry. Gas boiler structure compact boiler heating surface of the body, the inner heating surface, closely spaced outer disc configuration, the inner coil is a radiation heating surface, an outer surface of the outer coil and the inner coil constituting the convection heating surface. A boiler combustion chamber with a lower and upper body, a combination of the construction site. After combustion combustion combustion chamber, most of the heat is absorbed by the radiation heating surface, high temperature flue gas enters the convection heating surface for heat exchanger, after the boiler combustion air required for heating the boiler air preheater, and then through the filter the fumes to the chimney draft fan into the atmosphere. Easy installation, as long as the upper body and the lower combustion chamber can be closed, short installation period. Heating disk surface using the close-packed tubes, sufficient heating surface is arranged to reduce heat load surface of the tube, to make safer. Media reasonable process, low-Tian (imported) to (export), the gas generated by the operation, to better improve the thermal efficiency of the boiler. The fuel in the combustion chamber of the adiabatic combustion, combustion ignition make easier, more complete combustion, improved thermal efficiency and better crossing. Boiler top close-packed arrangement of coils, to better protect the roof, the roof to avoid burnout phenomenon.
Luzhou, Sichuan issued a notice to win the Battle of Blue Sky embodiment. Program requirements, to promote ultra-low emissions to upgrade the steel and cement industries, and increase efforts to eliminate small coal-fired biomass fired grate wood pellet boiler for hotels, phasing out the whole 10 tons / hour and below the coal-fired boilers. Details are as follows.
1, to accelerate the development of clean energy. Scientific and orderly promote clean energy development and utilization of hydropower, natural gas (shale gas), wind power, solar, biomass and so on. By 2020, the city's total primary energy consumption of 12.48 million tons of standard coal, total coal consumption control in less than 6.5 million tons, accounting for the proportion of total energy consumption control in less than 42%, the newly constructed and put into operation a large municipal solid waste incineration power plants, garbage power generation capacity of 12MW, a new wind farm installed capacity of 48MW, the development of distributed PV installed capacity of 5MW, the new large biogas 5. Improve the construction of reservoirs for natural gas production and marketing system.
2, to promote the use of clean coal. Efforts to increase coal washing, coal simultaneous construction of new coal washing facilities, supporting the completion of existing coal mines coal washing facilities in accordance with points Area. Improve coal quality and use of standard industrial, commercial coal do not comply with environmental standards required by regulations of coal quality merchandise. Prohibit the circulation and use of low-grade bulk coal, bulk coal investigated and dealt with according to the law without a license behavior. Increase the civil bulk coal clean governance efforts to promote electricity instead of coal, substitution of gas for coal, to promote the use of clean coal, advanced civilian stoves, strengthen civil bulk coal management. Strengthen regulation and control coal use in autumn and winter.
3, to carry out comprehensive improvement of coal-fired boilers. Increase efforts to eliminate small coal-fired boilers. By 2020, the county level and above cities phasing out the built-up area per hour and 10 tons of steam coal-fired boilers, in principle, to a new 35 tons of steam per hour of coal-fired boilers, in principle, to other parts of the new 10 per hour tons of steam coal-fired boilers. Ambient air quality standards are not areas should further increase efforts to eliminate.
4, increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate network and bulk coal fired boilers within the coverage area. In areas not have cogeneration district heating conditions, a plurality of existing coal-fired boilers of small, actively promote the implementation alternative energy.
