Compact anti-coking nozzle type biomass burner

Abstract

The invention discloses a compact anti-coking nozzle type biomass burner. The biomass burner mainly comprises a front replaceable sleeve nozzle, a rear feeding comprehensive device and a bottom air distribution auxiliary comprehensive device; and a main body adopts a double-layer sleeve structure, an inner sleeve is used for gasifying burning, and an outer sleeve is used for blast cooling protection. According to the burner, an economic and efficient rotary fire rabbling and ash removing device is adopted, in cooperation with a three-level multi-directional three-dimensional air distribution nozzle type structure design, the environment and working condition applicability is high, and the practicability is high; the biomass heat energy application technology is clean, efficient, energy-saving, environment-friendly, stable in operation, simple and convenient to operate, capable of preventing coking and wide in fuel applicability; and a feasible popularization scheme can be provided for new type urbanization, agricultural modernization and transformation of clean energy of various medium-and-small-sized coal-fired boilers in China, and remarkable economic and social benefits can be expected.

Description

technical field [0001] The invention relates to a compact biomass burner with a simple structure, in particular to a universal compact anti-coking rotary fire ash cleaning nozzle type biomass burner, which belongs to the technical field of biomass heat energy equipment. Background technique [0002] In recent years, with the gradual depletion of traditional fossil energy, the energy crisis and environmental pollution have attracted more and more attention from the society. Therefore, it has become a trend to explore and develop new clean alternative energy on a global scale. Biomass energy technology has received widespread attention and recognition for its unique properties of low pollution, sustainability, and neutral carbon emissions; among them, the biomass pellet fuel known as "solid natural gas" is currently the most in-depth research and the widest application range A biomass energy application technology; Compared with traditional fossil fuels, biomass pellet fuel not...
