Abstract

The invention provides a biomass gasification circulating system driven by a water pipe type condensing saturated steam boiler. The system comprises a water pipe type condensing saturated steam boilerand an atmospheric pressure fixed bed biomass gasifier, the boiler provides preheating heat energy, material transportation power and circulating cooling water for the biomass gasifier, and the biomass gasifier is used to realize atmospheric gasification of biomass. The system innovatively integrates the atmospheric pressure fixed bed biomass gasifier and the water pipe type condensing saturatedsteam boiler together to realize heat energy recycling, a gasification pipeline is designed as a circular pipeline structure, and a gasification agent and the circular gasification pipeline are integrated and designed together, so that the biomass gasification efficiency is improved. The whole system integrates boiler heat energy utilization, biomass preheating drying and gasification reaction, slag collection, gasification gas dust removal, oil removal and condensation together, and a traditional split-type gasification apparatus is changed, so that the biomass gasification efficiency and heat energy utilization efficiency are relatively high, and the overall layout and application are relatively convenient.

Description

technical field

[0001] The invention relates to the technical fields of carbonaceous material gasification technology and thermal energy recycling technology, in particular to a biomass gasification circulation system driven by a water tube condensing saturated steam boiler, that is, a biomass gasification and boiler steam circulation system. Background technique

[0002] The gasification of carbonaceous substances can produce combustible gases (hydrogen, carbon monoxide, etc.) for industrial use, and has broad application prospects in the field of modern chemical technology. Bed gasifiers, especially fixed-bed gasifiers with normal pressure, have a basic structure including a gasifier and an independently installed dust removal and purification device. The gasification agent is also input through the bottom of the gas output port. The gasification efficiency of this gasification furnace in the prior art is low, especially for the gasification efficiency of biomass. The exis...
