Combustion air supply system in biomass combustion furnace, combustion furnace and heating device

Abstract

The invention firstly provides a combustion air supply system in a biomass combustion furnace. The combustion air supply system comprises a small fan, an air blower and an air distribution tank which are sequentially connected in series, wherein the small fan is a fan which is powered by a battery and has the power of 10 to 200 w; the air blower is a fan which has fan power higher than the power of the small fan and is used for providing main fresh air for the combustion furnace; the air distribution tank is used for distributing fresh air and comprises a plurality of outlets which are connected in parallel; and the plurality of outlets which are connected in parallel are respectively connected with a main blast pipe, a discharge pipe anti-backfire blast pipe and blast pipes for other purposes. The combustion air supply system provides a safe and efficient working environment for the biomass combustion furnace. The invention further correspondingly provides a combustion furnace and a heating device.

Description

technical field [0001] The invention relates to the technical field of combustion equipment, in particular to a combustion gas supply system in a biomass combustion furnace, a combustion furnace and heating equipment. Background technique [0002] In the more than 100 years since the production and promotion of flue-cured tobacco, coal-cured tobacco leaves have a history of more than 50 years. Coal-cured instead of the original wood-cured is a great progress in the history of tobacco curing. To protect forest resources and ecological environment have made important contributions. In recent years, the tobacco industry has absorbed foreign experience and technology and successfully developed and promoted intensive curing rooms. From traditional curing rooms to intensive curing rooms, this is another major progress in the history of tobacco curing, which has significantly improved energy utilization and effectively reduced Baking costs. However, intensive barns have not funda...

Problems solved by technology

[0007] In addition, specific to the combustion furnace, the existing biomass pellet combustion furnaces often cause coking during combustion in the furnace due to the quality of the particles, which affects the combustion efficiency, and even causes the combustion furnace to be blocked and flamed out in severe cases.

In addition, many existing combustion furnaces require manual and regular cleaning of the furnace before they can be used, which affects efficiency and causes waste of resources
