Reverse combustion multi-pass biomass low-carbon energy-saving hot water boiler

Abstract

The invention discloses a reverse combustion multi-pass biomass low-carbon energy-saving hot water boiler which comprises a secondary reverse combustion hearth (1), a grate (2), a reverse combustion gasification hearth (3), a secondary air door (4), a high-temperature secondary air inlet (5), a biomass fuel charging opening (6), a water jacket (7), a fire banking and exhaust port (8), a pass fire outlet (9), a pass fire inlet (10), a multi-pass fire tube (11), an induced fan connection port (12) and a reverse combustion port (13). Pipelines of the hot water boiler are vertically arranged, and flames are moved in one of the vertically arranged pipelines from bottom to top and are returned in another pipeline from top to bottom, thus forming multi-pass reverse combustion. The reverse combustion multi-pass biomass low-carbon energy-saving boiler is made of iron plates and iron tubes. The invention has the advantages of complete combustion, low carbon content and energy saving, and can change wastes into valuables, reclaim resources and purify environment, thereby being beneficial to the nation and people.

Description

technical field [0001] The invention belongs to a biomass low-carbon energy-saving hot water boiler, in particular to a reverse-burning multi-pass biomass low-carbon energy-saving hot water boiler. Background technique [0002] Due to the energy shortage and environmental degradation caused by the massive use of fossil fuels, seeking a renewable energy source has become an urgent problem to be solved. Up to now, people are still burning straw, wasting resources, and polluting the environment. Biomass is a renewable energy source. , should occupy the main position in the boiler fuel. In winter, in northern China, people still use traditional coal-fired hot water boilers. Most of its combustion methods are direct combustion, sudden combustion, and no secondary air distribution. Most of the heat generated by combustion will be directly discharged into the atmosphere with the chimney, resulting in high energy consumption, high emissions, large fuel consumption, and low heat uti...
