Self-forming combustor for biomass powder

Abstract

The invention discloses a self-forming combustor for biomass powder. During work, the biomass powder stored in an outer storage bin is conveyed to a material forming device through a feeding mechanism, hot air in a hearth of the combustor enters the material forming device through an auxiliary heat ventilation pipe, the temperature of the material forming device is increased, the materials have the forming condition, a feeding motor drives a spiral propelling device to convey the biomass powder in the material forming device into a combustor furnace to be combusted, and an oxygen sending combustion fan is used for maintaining the combustion state. On one hand, the biomass forming materials directly enter the combustor furnace to be combusted, no requirements exist for the material forming density and shape, the using cost is low, and energy saving and equipment utilization increasing are facilitated. The biomass directly-formed materials are loose in structure, sufficient combustion in the combustor furnace is facilitated, the oxygen sending combustion fan generates spiral wind in the hearth, the wind pressure is increased, residues obtained after combustion can be better blown out, and the problem of scorification in the hearth is thoroughly solved.

Description

technical field [0001] The invention relates to the technical field of biomass treatment, in particular to a biomass powder self-forming burner. Background technique [0002] With the tense energy conditions such as electricity shortage, oil shortage, rising electricity prices, and rising oil prices, as well as the increasingly severe environmental pollution problems, various industries have gradually strengthened their awareness of the use of renewable energy, among which the use of biomass energy is currently the most feasible solution. Biomass is the substance existing on the earth, including all animals, plants and microorganisms, as well as many organic matters derived, excreted and metabolized by these living substances. All kinds of biomass have certain energy. Biomass is the carrier and the energy produced by biomass is biomass energy. Biomass energy is a form of energy in which solar energy is stored in organisms in the form of chemical energy, directly or indire...

AI Technical Summary

Problems solved by technology

[0004] However, the existing biomass burners in the market can only burn regular pellets, and biomass pellets need professional equipment to process, resulting in the problem that the fuel cannot be obtained locally, processed and used locally, and it also makes The cost of fuel is several times higher than the cost of burning coal; at the same time, the existing biomass burners have problems such as incomplete combustion and unreasonable oxygen distribution, which lead to black smoke during combustion, and the amount of smoke and dust is large, causing secondary pollution to the environment; moreover , the existing burner has many defects such as inability to automatically discharge slag after combustion, poor control of firepower and low degree of automation, which lead to the problems of high labor intensity for operators and poor temperature control effect
