A kind of biomass pellet fuel heating equipment

Abstract

The invention provides a biomass pellet fuel heating appliance, comprising a combustion furnace, a heat exchanger, a central supply system for supplying biomass pellet fuel to the combustion furnace, and a barn; the heat exchanger is used for being connected to one end of a horizontal nozzle of the combustion furnace, the barn includes a heating chamber, the heat exchanger is disposed in the heating chamber, and the combustion furnace and the central supply system are disposed outside the barn; the central supply system is used for providing biomass pellet fuel centrally for more than two combustion furnaces and comprises a suction unit with a vacuum pump, a storage barrel, more than two suction pipes, more than two feed pipes, a screw feeding mechanism, a feeding distribution connector, more than two electromagnetic valves, more than two vacuum buckets and more than two gravity valves. The heating appliance provided herein is reasonable and practical in design, safe and green, and efficient and labor-saving, reduces cost, saves resources, improves work efficiency and enterprise economic benefit, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to the field of combustion heat supply, and more specifically relates to a biomass pellet fuel 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 fundamentally solved the current situation of baking with coal a...

Problems solved by technology

[0006] However, in the biomass combustion furnace involved in the above scheme, the biomass particles are in a state of suspended combustion in the furnace. Although the combustion can be relatively sufficient, the density of the biomass particle fuel is not low, so it needs to provide a lot of energy for its suspension combustion to ensure Combustion efficiency, the economy of this scheme is low

If the biomass particles in the combustion furnace cannot be kept in a good suspension state, the problem of coking and agglomeration will easily occur in the combustion furnace and cannot be fully burned.

Have again, when running into sudden accidents such as power outage, this combustion furnace can only shut down and abandon

In addition, the heat exchange efficiency of the corresponding heat exchanger of the combustion furnace also needs to be improved
