Straw gasification furnace capable of continuously producing gas

Abstract

The invention discloses a straw gasification furnace capable of continuously producing gas. Straws which are cut up are fed into a material storage tank, the straws placed in the material storage tank are conveyed into a rolling tube type furnace rake by a spiral feeding machine, after the rolling tube type furnace rake is fully filled with the straws, a driving motor rotates to drive the rolling tube type furnace rake to rotate, and a plastic bottle is extruded so that diesel oil can be uniformly sprayed onto the straws in the rolling tube type furnace rake. The straws sprayed with the diesel oil are ignited by the flame of a pistol type long pipe gas ignition gun, wind blown out from a blast blower supports the smouldering of the straws in the rolling tube type furnace rake, the straws can generate a large amount of carbon monoxide during the smouldering, fireproof ceramic balls or metal balls in the rolling tube type furnace rake stir the straws so that the uniform smouldering of the straws can be realized, coal tar generated by the smouldering is heated and decomposed into low-molecule combustible gas when passing through two layers of double-layer honeycomb-shaped metal nets of the back section of the red burnt rolling tube type furnace rake, hot smoke gas heats the wind blown out from a boiler and the blast blower, the generated vapor and hot wind enter an air outlet pipe, and humid and hot air supports the smouldering of the straws, the combustible gas content in the smoke gas can be increased, and the smoke gas is cooled.

Description

Technical field: [0001] The invention relates to a straw gasification furnace capable of continuous gas production. Background technique: [0002] At present, biomass power plants have used combustible gas produced by circulating fluidized bed biomass gasifiers to burn boilers. The principle of the fluidized bed biomass gasifier is to continuously put biomass materials (for example: wood chips, leaves) into the fluidized bed covered with sand, ignite the biomass on the fluidized bed, and use compressed air to Or compressed oxygen-enriched air blows the sand above the fluidized bed together with the burning biomass from below the fluidized bed; since the sand absorbs most of the heat generated by the burning of biomass, the biomass is incompletely burned and has no flame Smoldering and producing fumes with large amounts of combustible gases (for example: carbon monoxide, hydrogen, methane, charcoal particles, coal tar and dust). Then the flue gas is cooled, dust removed, an...
