Abstract

The invention discloses a combined type energy-saving biomass fuel boiler. According to a waste heat recovery device, a waste heat chamber is of an inner layer and outer layer structure, a dust remover is arranged on the inner layer, a waste heat tank is arranged on the outer layer, the upper end of the waste heat tank is fixedly communicated with an air inlet pipe, the air inlet pipe is fixedly connected with an air blower, the lower end of the waste heat tank is fixedly communicated with a waste heat main air pipe, the waste heat main air pipe is respectively and fixedly communicated with multiple first waste heat branch air pipes and/or multiple second waste heat branch air pipes, the first waste heat branch air pipes arranged on the bottom of a fire grate are fixedly connected with a first oxygen supplying chamber, and the second waste heat branch air pipes are fixedly communicated with a second oxygen supplying chamber. Primary oxygen supplying and secondary oxygen supplying are adopted in the combined type energy-saving biomass fuel boiler, the combustion of fuel is more sufficient, the emission of nitrogen dioxide of the boiler is reduced, the pollution of soot is reduced, the waste heat of a chimney is fully utilized to enable the cold air of the air blower to be converted into hot air, the gasification degree of the fuel of a biomass combustion engine is improved greatly, and the temperature of flames of a combustion chamber and the temperature of flames of flaming nozzles are improved.

Description

technical field [0001] The invention relates to a boiler device, in particular to a combined energy-saving biomass fuel boiler. Background technique [0002] At present, various energy-saving boilers continue to appear in our country, and the technology is constantly reforming and innovating. According to the "Boiler and Boiler Room Equipment" published by China Construction Industry Press in December 1990, and the "Biomass Fuel User's Manual" published by Beijing Chemical Industry Press, they introduced the various types of biomass fuel in recent years. The structure of various types of boilers and the use of biomass burners. These boilers have made great achievements in how to increase the fuel combustion value, improve thermal efficiency, and save energy. However, with the continuous development of science and technology, the original boiler structure And combustion mode and heat efficiency all satisfy far away and can't adapt to the needs of modern society.
