Biomass gasification automatic-control boiler

Abstract

The invention discloses a biomass gasification automatic control boiler. The upper part of the ash removal grate is a furnace, the upper rear part is a secondary combustion chamber, and there is a fire baffle with a sandwich structure in the middle. Between the lower end of the fire baffle and the ash removal grate is a The flue gas channel, the furnace, the fire baffle and the secondary combustion chamber and the top are interconnected interlayer water jackets. The primary air is supplied to the furnace in multiple directions of the furnace. The secondary air is supplied to the secondary combustion chamber through the secondary air channels and through holes on the spoiler. An upper settling chamber is arranged above the furnace, which is communicated with the secondary combustion chamber by a fire pipe. In addition, a settling and flue conversion chamber and a lower settling chamber are arranged, which are connected by a fire pipe. The ash removal grate is a lift grate that can rotate around the front positioning pin shaft, and is used to adjust the height of the opening between the lower end of the fire baffle and the ash removal grate. The microcomputer control device can automatically control the operation of the boiler according to the set requirements. The invention can use biomass fuel and coal, has high efficiency and low emission, and meets the requirements of environmental protection and energy saving.

Description

technical field [0001] The invention belongs to the technical field of hot water heating boilers, and in particular relates to a biomass gasification automatic control boiler. Background technique [0002] Invention patent "a coal-fired water heating furnace" (patentee: Zaozhuang Duole Heating Equipment Co., Ltd., patent number: ZL 01127545.6) discloses a coal-fired water heating furnace. Both are equipped with air inlet plates, and the secondary air is introduced from above and below the entrance of the flue gas channel at the lower rear of the furnace. The combined heat exchange device of the structure can fully absorb the heat generated by coal combustion, and the combustion and temperature of the furnace can be controlled by adjusting the temperature adjustment damper and the opening and closing of the furnace air inlet. device, this kind of water heating furnace has low emission of air pollutants and high thermal efficiency. But it also has some points worthy of impro...

AI Technical Summary

Problems solved by technology

But it also has some points worthy of improvement: it is not suitable to use biomass fuel, such as straw briquettes, and it is suitable for a single fuel; the operation control mechanism is a bit complicated, which can be simplified and improved; the internal structure layout can be further optimized on the existing basis set up
