Problems solved by technology

Biomass carbonization technology produces three-phase products through high-temperature pyrolysis of cellulose, hemicellulose and lignin, namely solid-phase product biochar, liquid-phase product wood vinegar and wood tar, and gas-phase product wood gas. However, carbonization technology generally has problems such as low production efficiency and heat utilization rate, which are difficulties affecting the application of biomass carbonization technology.

Description

technical field [0001] The invention belongs to a clean energy heating system, in particular to a bio-light complementary heating equipment, which belongs to the technical fields of waste heat utilization of biomass carbonization technology and solar heat utilization. Background technique [0002] The active solar heating system utilizes the inexhaustible solar energy resources to obtain the heat source through the photothermal effect, but the solar energy has obvious dispersion, discontinuity and instability. The heating load also has obvious seasonality, and has great fluctuations in different periods of the heating season and at different times of the day. In order to ensure the heating needs of users, corresponding auxiliary heat sources are needed to provide supplementary heat. [0003] Bio-light complementary heating refers to the use of biomass as energy as an auxiliary heat source for active solar heating systems, and it is one of the important ways to solve the pro...
