Biomass environmental-friendly energy-saving steam boiler of spiricle fire tube

Abstract

The invention discloses a biomass environmental-friendly energy-saving steam boiler of a spiricle fire tube. The steam boilder is composed of a back combustion opening (1), a flame inlet (2), a flame outlet (3), a spiricle fire tube extruded edge (4), a spiricle fire tube (5), a water sleeve (6), an ellipsoidal end (7), a charging opening (8), a semi-gasification furnace chamber (9), a water grate (10) and a secondary combustion chamber (11), wherein the spiricle fire tube is welded in a furnace body vertically or horizontally, and the furnace body is sealed up and down with the flame inlet and the flame outlet remained; when in combusion, the flame enters the fire tube, is not discharged upward directly, but is guided by the extruded edge in the spiricle fire tube. The steam boiler provided by the invention has the advantages of full combustion, high heat utilization ratio, energy-conservation and emmission reduction and favarable economic benefit, and is easy to popularize and implement.

Description

technical field [0001] The invention belongs to a steam boiler, in particular to a biomass environment-friendly and energy-saving steam 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 industry, coal-fired steam boilers are usually used to maintain products, heat them for processing, or also use them for heating. The general steam boiler combustion is to burn coal directly, use a smooth and straight fire tube with a smooth inner wall, through the heat conduction of this fire tube to increase the water temperature and generate steam, so as to achieve the...
