Biomass gasifier/industrial gas boiler combined high-efficiency heating system

Abstract

The invention discloses a biomass gasifier/industrial gas boiler combined high-efficiency heating system. The system utilizes steam generated by the industrial gas boiler, part of the steam is supplied to the gasifier for gasification as a gasification medium, and the steam and air are combined for gasification, thereby being beneficial to enhancing the stability and quality of the biomass gas. The preheated air is supplied to the industrial gas boiler as combustion-supporting gas, thereby enhancing the overall heat efficiency. The electrolyic decoking cracking device can crack tar in the biomass gas, thereby enhancing the stability of the biomass gas and being beneficial to combustion of the biomass gas. Meanwhile, the system is subjected to water cooling through a full water cooling jacket, thereby effectively avoiding coking in the biomass gasifier. The system is applicable to the field of boiler heating systems.

Description

Technical field [0001] The invention relates to the field of boiler heating systems, in particular to a combined high-efficiency heating system of a biomass gasifier and an industrial gas boiler. Background technique [0002] Biomass energy has been widely used as a renewable, non-polluting clean energy. Biomass gasification and combustion is one of the main ways of efficient utilization of biomass. Biomass gasification and combustion generally use dedicated biomass gasification furnaces and The supporting biomass boiler system currently has a relatively complete implementation structure and has achieved certain industrial applications. However, there are many problems in the actual operation process, and there are many existing technologies that need to be improved and developed, as follows: [0003] 1) The body structure of the existing biomass gasifier design is built with refractory materials, which are expensive and have a short service life; [0004] 2). Biomass gasification ...

Problems solved by technology

[0003] 1) The body structure of the existing biomass gasifier design is built with refractory materials, which are expensive and have a short service life;

[0004] 2) Biomass gasification generally uses air as the gasification agent. Although the structure is simple, the calorific value of biomass gas is low and the gasification efficiency is not high;

[0005] 3) Because the biomass gas produced by biomass gasification contains a certain amount
