Biomass low-carbon energy-saving boiler with spiral grain fire tube

Abstract

The invention discloses a biomass low-carbon energy-saving boiler with a spiral grain fire tube, mainly comprising a secondary burning chamber (1), a boiler bridge (2), a semi-gasification burning chamber (3), a feeding door (4), a banking smoke outlet (5), a fire outlet (6), a fire inlet (7), a water jacket (8), a spiral grain fire tube (9), a spiral grain fire tube convex edge (10), a smoke drum joint (11), an ash cleaning door (12) and a back burning port (13), wherein the spiral grain fire tube is vertically welded or welded in a boiler body in a balanced manner, the upper part and the lower part of the spiral grain fire tube are sealed, the fire inlet and the fire outlet are provided, and in burning, the flame enters the fire tube and is directed to move by the convex edge in the spiral grain tube without rising or being discharged directly. The biomass low-carbon energy-saving boiler has the advantages of full burning, high heat utilization ratio, energy conservation, emission reduction, easiness for promotion and implementation and better economic benefit.

Description

technical field [0001] The invention belongs to a biomass low-carbon energy-saving boiler, in particular to a biomass low-carbon energy-saving boiler with spiral fire tubes. Background technique [0002] Due to our consistent and unrestrained use of non-renewable resources such as coal, the utilization of non-renewable energy is becoming increasingly tense. Every year, farmers burn a large amount of straw and other crops in vain, which not only wastes biomass resources, but also causes serious air pollution. In this case, the prospect of rational development and utilization of biomass resources is very broad. In winter, in the northern region of our country, heating issues have always occupied an important position and often become the focus of people's attention. The boiler is a relatively common heating device. Our general boiler combustion feature is to directly burn coal, use a smooth and straight fire tube with a smooth inner wall, and increase the water temperature t...
