Abstract

The invention discloses a biomass fuel pulse combustion hot blast device and a use method thereof. The biomass fuel pulse combustion hot blast device adopts the technical scheme by including a base (20), wherein a Rijke pulse combustor main body is mounted on the base (20); the Rijke pulse combustor main body includes a furnace chamber barrel body (16), a lower air pipe (4) and an upper air outlet pipe (9) from bottom to top; a grate (17) is mounted at the L position x=(0.12 to 0.26) away from the lower end of the Rijke pulse combustor main body; a rotary distributing rod (6) is arranged on the grate (17); and a feeding device including a feeding and speed regulating motor (7) and a spiral feeder (8) is arranged on the side wall of the furnace chamber barrel body (16). When the biomass fuel pulse combustion hot blast device is in use, the temperature in the combustion chamber is kept between 800 to 950 degrees. The biomass fuel pulse combustion hot blast device and the use method thereof solve the problems of insufficient combustion, caking and slag bonding during the biomass fuel combusting process, and provide a heat source with simple structure, efficiency in combustion and low manufacturing and use costs for drying agricultural products and the like.

Description

technical field [0001] The invention relates to a hot air heating device, in particular to a biomass fuel pulsating combustion type hot air heating device and its application method. Background technique [0002] The hot air heating furnace is a widely used hot air heating device, but it has problems such as complex structure, high cost, and low thermal efficiency. People have been looking for a hot air heating device with simple structure, low cost and wide fuel sources. [0003] Biomass is the fourth largest energy source in the world after coal, oil and natural gas. At present, the consumption of biomass fuel has accounted for 14% of the world's total energy consumption, and this proportion is as high as 38% in developing countries. It is estimated that, The land on the earth produces about 100 billion tons to 125 billion tons of dry biomass annually, and the ocean produces 50 billion tons of dry matter annually, and the total amount is equivalent to 10 times the world's...
