A biomass hot blast stove

Abstract

The invention discloses a biomass hot blast stove and belongs to the technical field of hot blast stoves. The biomass hot blast stove comprises a feeding motor (A), a material barrel (B), a screw feeder (C), a hearth fan (D), a hot air cavity air blower (E), a computer control system (F), a stove body (1), a hot air cavity (2), a hearth (3), a hot air cavity air outlet pipe (4), a heating chamber (5-1), a hot air box (5-2), a hot air outlet (6), a settling pond (7), a chimney (8), a chimney check hole (8-1), a hearth air inlet pipe (9), an ignition bar (10), an ash removing stove door (11), a stove grill (12), a stove door (13), a hot air cavity air inlet pipe (14) and a thermal insulation material (15). A secondary air feeding same-chamber three-dimensional burning mode is adopted, burning is thorough and efficient, tar is avoided, the burning efficiency is high, the heat conversion rate is high, an internal combustion system and an external hot air system are completely independent, automatic control is achieved, and the biomass hot blast stove is free of pollution when used for a long time.

Description

technical field [0001] The invention relates to a hot blast stove, in particular to a biomass hot blast stove, which belongs to the technical field of hot blast stoves. Background technique [0002] As a hot blast stove for thermal power machinery, the hot blast stove began to be widely used in my country in the late 1970s. It has become a replacement product for electric heat sources and traditional steam power heat sources in many industries. It mostly uses coal, coke, diesel, heavy oil, gas, etc. As fuel, but above-mentioned fuel can produce a series of harmful gas after burning, all caused very serious influence to environment and human body. [0003] With the development and progress of society, people pay more and more attention to the environment. Traditional hot blast stoves have been gradually replaced by biomass hot blast stoves. The so-called biomass hot blast stoves use biomass as fuel and produce less harmful gases than traditional fuels. . The traditional biom...

Problems solved by technology

However, because biomass generally has the characteristics of high moisture content, large fuel size changes, and high ash content, the above-mentioned biomass hot blast stoves have defects such as uneven air distribution, incomplete fuel combustion, low thermal efficiency, poor smoke and dust removal, and unenvironmental emissions.

It can be seen that the emergence of biomass hot blast stoves still does not solve the problem of environmental pollution well, so how to overcome the above technical problems and study a kind of biomass hot blast stove that is conducive to environmental protection has become a technical problem that needs to be solved urgently
