Integrated biomass self-powered cyclone gasification combustion furnace

technical field

The utility model relates to an integrated biomass self-powered cyclone gasification combustion furnace, which belongs to a biomass gasification furnace.

Background technique

Biomass is an important renewable energy source and the only renewable carbon source, which plays a decisive role in alleviating my country's energy crisis and improving the environment. Biomass gasification and combustion technology is one of the most important technologies for modern biomass energy utilization. It can significantly improve the thermal efficiency of biomass, reduce emissions and haze significantly, and effectively replace fossil fuels. Biochar is a pyrolysis product of biomass under anaerobic conditions, which has the characteristics of strong biological inertness, large specific surface area and high degree of aromatization. Studies have shown that biochar can exist in the soil for a long time, thereby steadily increasing the storage of soil carbon pool; at the same time, it can also improve soil structure and physical and chemical properties, improve soil water retention, fertilizer retention, aeration and soil biological activity. Heavy metals, pesticides, etc. pollute the soil, promote high and stable crop yields and improve the ecological environment, and are excellent soil amendments. However, at present, the vast rural areas still use traditional stoves for cooking and heating, and the smoke from cooking is curling up, and the firewood smoke and soot are added, causing serious environmental pollution.

In recent years, my country has made great progress in biomass gasification technology, but there are still many shortcomings. For example, the current large-scale biomass gas-coke cogeneration equipment cannot operate normally due to the large transportation radius of raw materials and low efficiency; Most of the current gas-coke co-production equipment is split type, which is difficult to promote due to tar blockage and pollution of pipelines; although some integrated semi-gasifiers have improved thermal efficiency, the biomass is completely burned and cannot produce biomass coke.
