Abstract

The invention relates to the field of biomass burning and provides an anti-coking method of a biomass burner cavity. The cavity is of interlayer structure, water in the interlayer cools the surface of the cavity, the cavity structure is good in liquid-solid heat exchange performance, and the temperature of the inner wall of the cavity is greatly lowered. The cavity structure contacts with ash-containing smoke of burned biomass and is not easy to coke on the surface, and performance of the biomass burner is greatly improved. The anti-coking method includes steps of acquiring the current cavity temperature; automatically adjusting inflow water amount of cooling water according to the difference of the current cavity temperature and the ideal working temperature. Accordingly, the problem of coking due to overhigh temperature of the cavity is solved.

Description

technical field [0001] The invention relates to the field of biomass combustion, in particular to a method for anti-coking a cavity of a biomass burner. Background technique [0002] Fossil energy pollutes the environment, and new energy, especially renewable energy, has become the development direction of the energy industry. Biomass has the characteristics of high volatile content, high carbon activity, low nitrogen and sulfur content, and low ash content. It is a clean and low-carbon energy source with dual attributes of environmental friendliness and renewable energy. It is a high-quality environmentally friendly fuel that can replace conventional fossil energy. At present, my country's biomass energy has been gradually applied, and the biomass burner technology has also made some progress. [0003] The cavity of the traditional biomass burner adopts a single-layer structure, which is built by insulating bricks, refractory (water) mud and other materials. This cavity st...
