4 ton biomass steam boiler
Fluidized Bed Combustion (FBC) 4 ton biomass steam boiler
Fluidized bed combustion (FBC) steam boiler for biomass boiler has emerged as a viable alternative and has significant advantages over conventional firing system and offers multiple benefits–compact boiler design, fuel flexibility, higher combustion efficiency and reduced emission of noxious pollutants such as SOx and NOx. The fuels burnt in these boilers include coal, washery rejects, rice husk, bagasse & other agricultural wastes. The 15ton hour coal fired fluidized bed boilers have a wide capacity range- 0.5 T/hr to over 100 T/hr.
In October 2016, my company and the China Dunhuang International Hotel signed a ZWNSL2.1-1.0 / W-Y.Q vacuum condensing gas hot water boiler to provide heating and hot water for the hotel. The boiler implementing the response to the national policy of environmental protection requirements and local environmental protection departments on a series of low nitrogen emission standard boiler requirements, in terms of design, manufacture, installation and other sectors have strict checks to ensure that the boiler safe and stable operation.
What a 4 ton biomass steam boiler performance was uneven heat? The following is a non-uniformity reasons: 1, non-uniform heat absorption of the steam boiler. Closely related to the arrangement, operation mode and the type of fuel causes nonuniform heat absorption of the burner. Uneven temperature distribution in the furnace, the heat causes a small load intensity of each furnace waterwall. In general, in the case where the same type of fuel, the heat load distribution in the furnace slagging liquid much larger than the heat load distribution in the furnace slagging solid. Fuel burner heat load is larger than the unevenness of the uneven heat load fired furnace, hot offset vertical tube panel screen than the horizontal tube thermal excursions. DC endothermic steam boiler unevenness different from the natural circulation steam boiler. Natural circulation steam boiler having a heat compensation characteristics, can play a major role in reducing thermal excursions, but the evaporator heating surface in direct steam boiler, heat absorption for larger tube, because the steam generation amount of the inner tube, large capacity . Increase the resistance, the flow rate of the steam pipe is reduced. Conversely, increasing the flow rate of weak heating pipes. Therefore, the DC steam boiler evaporator heating surface will not only cause non-uniform endothermic thermal excursions, but also to expand the non-uniform heat flow by influencing the deviation. 2. The flow rate of the steam boiler is not uniform. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. Different resistance to flow parallel to the tubes of the evaporator heating surface, and a change in pressure along the length of the header, and the difference in weight between the head tube and the tube will lead to non-uniform flow. Variation on the thermal flow resistance. Since the structure of the steam pipe, the quality, of different length, diameter, roughness and curvature, the flow resistance is different. Under the same pressure, the flow resistance can cause uneven. When the thermal head 2 in the high-pressure variation in the vertical riser screen, since the height of the larger screen, parallel tubes uneven heating, density vary greatly, it should consider the impact ram repositioning. When high heat load single tubes, the tube bundle of the flow decreases. However, due to the reduced density of the working fluid within the tube and the weight of the head is reduced, the flow rate increases. Accordingly, high pressure water is advantageous to reduce thermal excursions.
Recently biomass fired CFB boiler technology is spread increase quickly in Europe.CFB boiler technology can also can be called clean coal technology,which can make industrial boiler more efficiently and environment friendly.CFB boiler can burning biomass or coal as fuel to produce steam or hot water whatever you need.
