Two stage coal gas generator is composed of gasified reduction gas and dry run gas, which is divided into top gas and bottom gas, which is a collector. Electricity. The gasification project is mainly composed of coal preparation section for two sections of furnace. Electrical control. Coal adding section. Distillation section. Gasification section. The process flow of the ash discharging section and gasification agent preparation section is to design the fuel according to different requirements and quality requirements of the user.
The two-stage gas producer has two gas outlets, which can output different calorific value of gas. Its gasification efficiency and comprehensive thermal efficiency are higher than that of single-stage furnace. The coal is completely retorted in the upper section of the furnace, and the lower section gas basically contains no tar. The upper section gas contains a small amount of light tar, which is not easy to block the pipeline. The two-stage furnace gas has high and stable calorific value, large operation flexibility and high degree of automation Labor intensity is low. The two-stage gasifier gas station does not pollute the environment, saves water significantly, occupies a small area and has low long-term operation cost. Mechanical or hydraulic pressure can be used for grate rotation and coal feeding according to different requirements of users. The grate is heat-resistant and wear-resistant cast iron, which has better air permeability and is suitable for flue gas gasification process.
