Biomass bundled stack gasification heating boiler system

Abstract

The invention discloses a biomass bundled stack gasification heating boiler system. The biomass bundled stack gasification heating boiler system comprises a gasification bin, a hearth connected with the gasification bin through a premixing start-up burner, a convection heat-exchange face and a dust remover, wherein the convection heat-exchange face and the dust remover are sequentially connected to a flue gas outlet of the hearth. Biomass bundled stacks are partially burned through a gasification technology for heat supplying, main bodies are gasified to generate gas, and the energy quality isefficiently improved; the single biomass bundled stacks are gasified through arranged gasification chambers correspondingly, the multiple gasification chambers can be formed in parallel, thus the equipment modularization degree is high, using is convenient, the biomass bundled stack gasification heating boiler system can be applied to distributed energy development, the number of the gasificationchambers participating in operation can be adjusted according to the demands, and variable-load working is achieved; and a premixing area is arranged below a burning chamber, thus the gas generated after gasification needs to be filtered firstly through the biomass bundled stacks, the biomass bundled stacks self-filter the flue gas, denitration and dust removal of the flue gas are achieved through cooperation of low-nitrogen burning and tail dust removal of the start-up burner, and the production cost is low.

Description

technical field [0001] The invention relates to the field of biomass utilization, in particular to a biomass bundling gasification heating boiler system. Background technique [0002] The amount of agricultural waste biomass in my country is huge, and the biomass is widely distributed. If it is not utilized, it will not only waste resources but also bring a huge load to the environment. The current utilization forms of biomass mainly include fragmented, shaped pellets and bundles. Among them, the scattered utilization is not suitable for large-scale application, and the pollution is high; the molding pellets consume a lot of energy and are not easy to burn out; biomass bundling is easy to burn out and can be applied to large-scale production, which is the best biomass Utilize the form. At the same time, with the improvement of the degree of agricultural mechanization in our country, the conditions for large-scale biomass bundling production are already available. But at p...
