Biomass gasification automatic-control boiler

Abstract

The invention discloses a biomass gasification automatic control boiler. A furnace is arranged above an ash removal grate. A secondary combustion chamber is arranged above the back of the ash removal grate. The middle is equipped with a fireproof plate with a sandwich structure. A flue gas channel is arranged between the lower end of the fireproof plate and the ash removal grate. Sandwich water jackets, which are mutually communicated, are arranged on the periphery and the top of the furnace, the fireproof plate and the secondary combustion chamber. A primary air is supplied into the furnace from a plurality of directions of the furnace. A secondary air is supplied into the secondary combustion chamber through a secondary air channel and a ventilating hole on a spoiler. An upper settling chamber is arranged above the furnace, which is communicated with the secondary combustion chamber through a fire tube. In addition, a settling and flue conversion chamber and a lower settling chamber, which are communicated through a fire tube is arranged above the furnace. The ash removal grate is a lifting grate, which can rotate around an anterior location pin and is used to adjust the height of the opening arranged between the lower end of the fireproof plate and the ash removal grate. A microcomputer control device can automatically control the operation of the boiler according to the set requirements. Using biomass fuels and coals, the invention has the advantages of high efficiency and low emission, which accords with 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
