Biomass boiler device

Abstract

A biomass boiler device comprises an internal system, a water system, an air system and a flue gas utilization and purification system. The internal system comprises an outer shell , a combustion chamber, a hemispherical baffling cover, an upper-layer combustion mesh grate, a step-type mid-layer combustion mesh grate, a lower-layer combustion mesh grate, a temperature sensor and an ash residue chamber; the upper-layer combustion mesh grate, the step-type mid-layer combustion mesh grate and the lower-layer combustion mesh grate are sequentially embedded in the combustion chamber from top to bottom; the water system comprises a spiral water pipe, a first heat meter and a second heat meter, and the spiral water pipe is coiled outside the combustion chamber; the air system comprises an air preheater, a porous air spraying pipe, a vertical air pipeline, a first induced draft fan and a hydrometer; and the flue gas utilization and purification system comprises a cyclone separator, a gas returning pipe, a flue gas analyzer, a superheater, a reheater, a coal economizer, a dust remover, a second induced draft fan and a chimney. The biomass boiler device has the characteristics of high environmental protection index, reasonable grate structure, high combustion efficiency, high efficiency, energy conservation, high flue gas utilization rate and the like.

Description

Technical field [0001] The invention relates to the field of heat exchange devices, in particular to a new type of biomass boiler device. Background technique [0002] With the increasing depletion of petrochemical energy and the increasingly serious environmental problems, the development of renewable and environmentally friendly biomass energy is of great strategic significance. my country is rich in biomass energy. Biomass energy has the characteristics of high oxygen and hydrogen element content, high volatility, high carbon activity, low N and S content, low ash content, and good ignition performance. Its efficient conversion and clean utilization are increasingly popular in the world. Pay attention. [0003] Biomass can be converted and utilized through various methods such as direct combustion, pyrolysis, gasification, and liquefaction. Among them, the direct combustion technology is currently one of the most mature, simple and feasible methods suitable for large-scale, effi...

AI Technical Summary

Problems solved by technology

The key problem in the promotion and application of biomass fuel in my country is that there is no suitable combustion equipment. The research, design and manufacture of biomass combustion equipment are far from meeting the needs of industrial development. The research and development of biomass boilers is imminent.
