In the furnace of rice husk steam boiler, the front and back arches of water cooled whole casting are adopted. The front arch is trapezoidal and the back arch is herring-shaped, making the coverage rate of the arch close to 85, which is conducive to the combustion of biomass fuel. Rice husk fired boiler adopts large chain grate to achieve mechanical combustion. Equipped with drum induced draft fan for mechanical ventilation, and with slag machine to achieve mechanical slag, complete control monitoring instruments.
Automatic feeding rice husk fired steam boiler is a single drum type quick-loading three-return water and fire tube boiler, with large heating surface and high thermal efficiency. It can be widely used for ironing, drying, heat treatment in textile and clothing, printing and dyeing, food, chemical industry and other industries, as well as hotels, schools, guesthouses and enterprises and institutions steaming vegetables, steaming rice, supply of hot water or hot water, disinfection and so on. The air distribution of the boiler products is reasonable, which is conducive to fuel burning and improve the efficiency of the whole machine.
Rice husk fired boiler adopts a new type “α” arch, and a cyclone combustion chamber structure is designed in the furnace. When the boiler is running, the high-temperature flue gas can be rotated at high speed, mixed combustion and dust separation to achieve the effect of dust removal, energy saving and environmental protection in the furnace. At the same time, the front wall of the airfoil flue is arranged with secondary air, controlled by the valve, which is put into use when burning biomass, strengthening the combustion, so that it is fully burned out and improving the combustion efficiency.
Biomass rice husk steam boiler adopts scientific air distribution technology, air frequency control, high pressure head induced draft fan configuration, can effectively prevent the positive pressure combustion furnace. Suitable for multi-pipe cyclone dust collector + bag dust collector configuration, can meet strict discharge standards. The larger the biomass steam boiler tonnage, combustion more fully, the thermal efficiency of the boiler is higher, the corresponding biomass fired boiler operation cost will be lower. The boiler as a whole in the form of quick delivery, electric control to achieve stepless speed control grate, limit parameter alarm and interlock protection.
Rice husk fired boiler is water fire tube structure, using arch tube sheet thread smoke pipe, equipped with special feeding hopper and feeding machinery. The series of biomass fired boilers are optimally equipped with secondary air devices. The fuel is fed continuously and evenly from the hopper through the feeder, and the jet air is sent into the furnace, which moves back with the chain grate at a uniform speed to complete the combustion process. In the swirling furnace, the air moving field, mixed and sudden burning, completely eliminate the black smoke in the furnace. The upper barrel is longer and has a larger volume of soda water. There are convection tube bundles in the upper and lower drum, which can fully absorb the heat of flue gas.
