Biomass hot blast stove

Abstract

The invention relates to a biomass hot blast stove. The biomass hot blast stove comprises a hot blast stove body, a combustion chamber, an ash deposition chamber, an air inlet chamber, an air outlet chamber and a blower, wherein the combustion chamber comprises a first combustion chamber and a second combustion chamber; the first combustion chamber is connected with a first feed opening; the second combustion chamber is connected with a second feed opening; the ash deposition chamber is arranged below the second combustion chamber; an ash discharge opening is formed in the bottom of the ash deposition chamber; the air inlet chamber is connected with the blower outside the hot blast stove body; the air outlet chamber is arranged above the air inlet chamber; a hot air outlet is formed in thetop of the air outlet chamber; a first grate is arranged between the first combustion chamber and the second combustion chamber; and a second grate is arranged between the second combustion chamber and the ash deposition chamber. The biomass hot blast stove has the beneficial effects that a secondary combustion manner is adopted, combustion is sufficient and efficient, tar does not exist, the combustion efficiency is high, the heat conversion rate is high, an internal combustion system and an external hot air system are completely independent, the biomass hot blast stove is free from pollution after being used for a long term, and the environmental pollution is reduced; smoke and dust pass through a dust removal device arranged at a hot-blast outlet, so that the smoke and dust are free from black smoke, auxiliary facility is not needed for treatment, and discharge can achieve an environmental-friendly standard; and the biomass hot blast stove is reasonable in design, simple in structure, low in making cost, large in heating area, high in heat efficiency, simple and quick to use and low in maintenance ratio.

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. . However, because bio...

AI Technical Summary

Problems solved by technology

However, because biomass generally has the characteristics of high moisture content, large fuel size changes, and high ash content, resulting in 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
