1 4Mw Wood fired central heating boiler
In the transformation process, side by rapid technical engineers FGR advanced combustion technologies, the use of flue gas recirculation and the outer loop is provided, withdrawing part of flue mixed with the combustion air, and then into the furnace through a burner, not directly part in the combustion, by reducing the effect of the combustion flame temperature to reduce the temperature and oxygen concentration, to achieve the purpose of reducing NOx generation. For now, for a large volume of gas 1 4mw wood fired central heating boilers, low compared to the overall transformation of nitrogen to replace the boiler equipment will save a lot of costs. Fast boiler has a boiler in research and technology low nitrogen aspects of considerable industry experience, successful completion of the reconstruction project Dingzhou low nitrogen Erie boiler, significant cost savings for businesses.
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.
It features gas 1 4mw wood fired central heating boiler 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.
Wood waste steam 1 4mw wood fired central heating boiler is a type biomass fired steam boiler which mainly takes wood waste as its fuels. In Zimbabwe, there are over 70,000 tons wood waste generated from the timber industry each year. In the long-term, this figure is projected to double by 2015. At most large timber mills, only a small fraction (~10%) of wood waste is currently consumed in process steam boilers for lumber drying kilns, while the vast majority is burned in the open air or dumped. Therefore, there is large potential to build power plants and wood waste steam boiler is good choice which is not only energy-saving but also eco-friendly.
