Biomass boilers use the most suitable combustion equipment for biomass fuel combustion - reciprocating grate. In terms of structural design, the boiler has a larger furnace space than traditional boilers and a very reasonable arrangement of secondary air, which is conducive to the complete combustion of a large amount of volatile matter that is instantly precipitated when biomass fuel is burned. The boiler can be equipped with an ignition burner to realize ignition automation. The boiler's feeding, combustion, slag removal, water supply, and ignition can all be automatically controlled and operated very conveniently. The boiler is equipped with an automatic dust cleaning device that can promptly remove the dust accumulated on the heating surface of the boiler to ensure efficient and stable operation of the boiler. An economizer is arranged at the rear of the boiler, and an air preheater can also be arranged according to user needs. Compared with traditional boilers, the boiler efficiency is higher and the exhaust gas temperature is lower. Using high-efficiency insulation materials, the surface temperature of the boiler is low and the heat loss can be ignored. Produced in strict accordance with Chinese national specifications and standards, all pressure components are made of high-quality boiler steel. Each boiler must undergo strict inspection and testing before leaving the factory, including hydrostatic testing and radiographic testing. The installation of manholes, inspection doors, fire observation holes, etc. is very convenient for maintenance. The characteristics of biomass boilers are: energy saving, environmental protection and easy installation and use.
The efficiency of biomass boilers is generally above %. The larger the boiler model, the more complete the combustion, and the efficiency of the boiler will be higher. The highest reached .% higher than the average efficiency level of coal-fired boilers. Although biomass boilers are very efficient, they still produce dust that pollutes the environment. Therefore, a corresponding dust collector is needed to solve the problem. The biomass boiler dust collector came into being.
The treatment process of the biomass boiler dust collector is to treat the flue gas generated during the production process of each boiler separately. Flue gases from boilers. The dust enters the cyclone dust collector from the dust suction pipe. At this time, the large particles in the smoke are separated under the action of the centrifugal force of the cyclone dust collector. The large particles of dust are discharged from the cyclone dust collector and the fine particles of dust enter the bag dust collector. After the filter bag is filtered and pulse blowing is used, the dust adhering to the surface of the bag is first concentrated in the ash hopper of the dust collector and recycled or utilized by the discharge controller. The clean air processed by the bag dust collector is discharged into the atmosphere from the chimney through the fan. The treatment of boiler dust-containing flue gas through bag dust collector can reduce the pollution of flue dust to the surrounding environment and achieve the purpose of clean production.
Biomass boiler dust collector design principle:
The design and selection of dust removal equipment follow the principles of advanced technology, economy and practicality
The selected dust collector is reasonably designed, practical, reliable, advanced and operational. It has the characteristics of smoothness, low resistance, low energy consumption, good dust cleaning effect, and small floor space
. The design should save investment and reduce operating costs.
