Furnace head of biomass burning furnace

Abstract

The invention relates to a furnace head of a biomass burning furnace, which comprises a furnace mouth part, a furnace head cavity body (11), a furnace head feed port and a lower duct air inlet device, wherein the furnace head feed port is a feed pipe outlet (10) which is communicated with the furnace head cavity body (11) through a horn-shaped furnace bottom (4). A lower duct (6) of the lower duct air inlet device and a feed pipe (5) are arranged in an eccentric structure, and a gap toward a duct air inlet pipe (9) is bigger than a gap on one side far from the duct air inlet pipe (9). The furnace head of the biomass burning furnace feeds steadily and inlets air uniformly by adopting the horn-shaped furnace bottom and an eccentric air inlet structure, simultaneously, furnace charges burning location and relative positions are designed in advance. When furnace charges of the furnace head cavity body are lower than the location position, a feed device is started to feed. The position of the furnace charges must be higher than the location position which is a furnace charge burning relative position after feeding each time, and the furnace charges are located in a steady burning region when burning on the relative position. The furnace head of the biomass burning furnace enables the position of fuels in the furnace head cavity body to be kept steady, achieves continuous burning, and meets the demands of continuously using fire in a long time.

Description

technical field [0001] The invention belongs to household stoves or stoves with solid fuels, and relates to a fully-automatic biomass burning stove burner with fuel burning from top to bottom. Background technique [0002] The combustion device that uses the top-down combustion method for fuel has been continuously developed. The existing feeding device is "closed biomass fuel feeding device", patent number: CN200820185125.6. The flap door device of the device, the flap door device is provided with a fuel inlet, the lower end of the screw device communicates with a metering silo, and the metering hopper is equipped with a fuel level detection device; another example is the applicant CN201110072163.7 of "A Fully Automatic Feeding Furnace and Burner Fuel Feeding Device", which adopts the method of mobile replenishment and push-type feeding, and realizes continuous and uninterrupted fuel addition through circular replenishment and continuous advancement , which can meet the de...

AI Technical Summary

Problems solved by technology

Although continuous and uninterrupted fuel addition can be achieved, there are still some deficiencies in the control of the material level in the burner burner, and the relationship between the material level and the feed cannot be effectively controlled.

This shows that the prior art scheme is also difficult to meet people's actual needs
