Technical field
The present invention relates to technical field of coal chemical industry, more particularly to a kind of gas generator and control method.
Background technology
Gas generator is the production equipment that coal is converted into imflammable gas (coal gas), and the main component of coal gas is
CO、H2、CH4Deng.Its operation principle is will to meet after the coal screening of gasification process index, be added in gas burner by firing machine,
From furnace bottom self-produced steam is blasted with air gas mixture as gasifying agent；Coal Jing after physical and chemical reaction, is generated in stove
Imflammable gas, for users to use.
However, feed coal is added in stove by firing machine, due to the movement of falling object of coal during blanking, stove is hardly diffused to
Interior surrounding, causes bed of material surface in steamed bun shape, by the air-flow of surrounding more than middle air-flow, causes the chemical reaction of centre
Much more slowly than surrounding.In order to solve that enough spaces, i.e. dead level are left on the bed of material in the problem, stove, and by configuring cone
It is uniform that shape distributing device makes material block realize when falling.But, the coal gas of production can occur aggregation and side reaction occurs in dead level, make CO and
Unnecessary H2O reacts, and produces CO2And H2.Because the calorific capacity of CO is 3020KJ/Nm3, H2Calorific capacity be 2570KJ/Nm3；Institute
With, from heating effect for, this side reaction occurs loses more than gain.Even if additionally, being configured with adding for conic distributor
During coal machine blanking, it is also difficult to which the coal cinder for making freely falling body spreads too big area, and causing the diameter of gas generator could not exceed
3.2 meters, so as to limit the operating efficiency of gas generator.
