Tunnel combustion chamber and its constructed smoke dust less fuel coal and biomass equipment

Abstract

The tunnel combustion chamber and constitute of burning coal and organism without smoke and dust relate to boiler, furnace and aerify equipment whose fuel is coal and organism. The tunnel combustion chamber has wide fuel scope and can carry out the cleanness combustion of the smoke raw coal, the spread coal, the organism, the type coal and the biologic coal. The tunnel combustion chamber applies the biologic fuels reasonably and has high thermal efficiency and realizes the large-scale and mechanical burning. The invention resolves the problem of pollution atmosphere environment by coal burning device and makes the equipments the cleanness combustion when burning the coals. The small equipment doesn't need air blast and induced air and it can burn. And the tunnel combustion chamber doesn't need the ash handling equipment to protect the environment. The invention sends the vapour to the tunnel combustion chamber. It is used to restrain the smoke and translate to the gas fuel. It carries out cleanness combustion when realizes the increase the combustion value of the fuels. It lowers the resources depletion and relief the energy strain. It creates a condition for pushing economy social overall coordination sustained developing.

Description

Technical field [0001] The invention relates to coal and biomass equipment, in particular to boilers, kilns and gasification equipment using coal and biomass as fuel. Background technique [0002] my country is a big coal producing country and also a big coal consuming country. In my country's energy structure, coal is the primary energy source and is mainly used as boiler fuel. Coal is a relatively cheap energy source among conventional energy sources. The fuel cost of coal-fired boilers is less than a quarter of that of oil-fired boilers or gas-fired boilers. However, for a long time, the combustion process of coal-fired equipment has been dominated by direct combustion. There are phenomena of insufficient combustion, low thermal efficiency, serious waste of coal resources, and serious pollution of the atmospheric environment. Biomass energy is converted from solar energy through photosynthesis, mainly in the form of agricultural and forestry crops, and is the only renewa...

AI Technical Summary

Problems solved by technology

After searching the Chinese patent literature, there are more than 100 patents on briquette boilers, but most of them are hand-fired boilers, and there is no measure to eliminate soot. They can only burn anthracite briquettes. The degree is not high, and the operation is labor-intensive. There are also some briquette boilers that can burn smokey briquettes, but the measures for eliminating smoke and dust are not in place, and the requirements for clean combustion cannot be met.

[0006] The purpose of this invention is to solve the problem of coal-fired equipment polluting the atmospheric environment, so that the equipment can meet the requirements of environmental protection when burning anthracite or bituminous coal, and realize clean combustion to reduce environmental pollution
