Biomass particle hot-blast furnace

Abstract

The invention relates to a biomass particle hot-blast furnace which comprises a furnace body, wherein the furnace body is sequentially provided with a fire box, a flue connecting pipe, a sieve-plate heat exchange plate, heat-conducting plates and a furnace shell from inside to outside; and the lower part of the fire box is provided with a hearth; the outer wall of the hearth is a sieve-plate structure; the upper part of a furnace chamber formed by the heat-conducting plates is provided with a heat air inlet; an air inlet plate is arranged below the heat air inlet; and an outlet of the flue connecting pipe is connected with a deduster. The biomass particle hot-blast furnace has the advantages of high efficiency, environment friendliness, low carbon, low consumption, time saving, labor saving, low cost, long service life, high temperature control precision and high heat recovery rate (up to 80%), and can save the coal amount by 30% and save the firewood amount by 40%.

Description

technical field [0001] The invention relates to a hot blast stove, in particular to a biomass particle hot blast stove. Background technique [0002] As a thermal power machine, hot blast stoves began to be widely used in my country in the late 1970s, and have become replacement products for electric heat sources and traditional steam power heat sources in many industries. Most of them use coal, coke, diesel, heavy oil, gas, etc. as fuels. , but the above-mentioned fuels will produce a series of harmful gases after burning, which will have a very serious impact on the 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 biomass generally has the characteristics of high moist...

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, the above-mentioned biomass hot blast stoves have uneven air distribution, incomplete fuel combustion, and prone to fire failure during the heating process, slow heating and low thermal efficiency. Low, poor smoke and dust removal, unenvironmental emission, short service life and other defects

It can be seen that the emergence of biomass hot blast stoves still does not solve the above-mentioned many problems well, so researching a kind of biomass hot blast stove that is beneficial to environmental protection has become a technical problem that needs to be solved urgently.
