Problems solved by technology

However, due to the low energy density and small specific gravity of solid biomass in the gasifiers currently on the market, the gasification intensity of the gasifier is low, the gasification efficiency is low, and the calorific value of the gas is low.
The maximum gas production capacity of the currently operating fixed-bed gasifier is 900N 3 / h, calorific value 1000~1100kcae / Nm 3 Therefore, the scope of application of the gasifier is limited

Abstract

The invention provides a solid biomass semiwater gas generating furnace, which includes a furnace body, a transmission mechanism, a feeding mechanism and a residue discharging mechanism. A head preserving layer 2 and a fire resisting layer 3 are arranged in the furnace body, a heat exchanger pipe 4 is arranged in the fire resisting layer 3, and a material homogenizing harrow is arranged on the hearth. A clinker chamber 12 and a cooling water tank 13 are arranged on the underside of the furnace body 1, a gasification agent inlet 14 is arranged on the clinker chamber 12, and a clinker outlet 15 is arranged on the bottom of the clinker chamber which is connected with a spiral clinker discharger 17. A rotatable furnace grate is arranged on the interface of the hearth and the clinker chamber 12. The invention can feed material and discharge clinker continuously, ensures the continuous stability of the gasification process, uses the vapor generated by residual heat to participate in gasification reaction, improves the carbon utilization rate, and improves the gasification rate of the solid biomass. Compared with gasification furnace with uniform section, the gasification strength of the invention is improved by 1.5-2.0 times, and the combustible gas calorific value is doubled.

Description

1. Technical field [0001] The invention relates to a chemical equipment, in particular to an energy conversion equipment, in particular to a generator which uses low-density solid biomass as a raw material to generate semi-water gas. 2. Background technology [0002] There are many kinds of equipment for converting low-density agricultural and forestry solid waste such as straw into gas fuel through pyrolysis and gasification. However, due to the low energy density and small specific gravity of solid biomass in the gasifiers currently on the market, the gasification intensity of the gasifier is low, the gasification efficiency is low, and the calorific value of the gas is low. The maximum gas production capacity of the currently operating fixed-bed gasifier is 900N 3 / h, calorific value 1000~1100kcae / Nm 3 Therefore, the scope of application of the gasifier is limited. 3. Contents of the invention [0003] The generator provided by the invention is aimed at producing hig...
