Biomass back-burning multi-return low-carbon energy-saving blast stove

Abstract

The invention discloses a biomass back-burning multi-return low-carbon energy-saving blast stove, which consists of a stove door (1), a biomass back-burning hearth (2), a biomass back-burning fire hole (3), a biomass hearth (4), a biomass charging hole (5), a refractory material (6), a cold air inlet (7), a sealing plate (8), an air partition board (9), a biomass multi-return fire tube (10), a hot air outlet (11), a smoke receiving pipe hole (12) and an access door (13). The fire tube of the blast stove is vertically welded. A layer of refractory material is filled and compacted below the fire tube. Flame flows bottom up in the vertical tube and then returns top down in another channel to form a plurality of back-burning returns. The blast stove is made from iron plates, iron pipes and the refractory material. The biomass back-burning multi-return low-carbon energy-saving blast stove realizes full burning, has long service life, and is energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to a hot blast stove, in particular to a biomass back-burning multi-pass low-carbon energy-saving hot blast stove. Background technique [0002] Due to the energy shortage and environmental degradation problems caused by the extensive use of fossil fuels, biomass as a clean energy has occupied a major position in fuels. With the development of productivity and the acceleration of agricultural modernization, facility agriculture has developed by leaps and bounds in recent years. Among them, plastic greenhouses account for a large proportion. At present, in northern my country, in order to solve the problem of heating and heat preservation of greenhouses in winter, most of them use hot air stoves. The tubes in the furnace are welded horizontally, and the tubes are directly placed on or in the furnace, so that they are very close to the fire. Because there is no water in the pipe, there is hot air in the pipe, and the pipe will bu...
