powered, and vapor solenoid valve (22) energization is beaten when the inner vapor pressure of boilers heated electrically (21) reaches setting value It opens, the vapor of boilers heated electrically (21) reenters vapor tank (20)；The coal gas come out from coal gas waste heat boiler (11) enters Wind in gas pipe heating gas heater heated by waste heat (12) cooling duct of coal gas heater heated by waste heat (12), from coal gas waste-heat The coal gas that device (12) comes out enters gas desulfurizer (13) scrubbing CO_2, the coal gas come out from gas desulfurizer (13) Coal gas enters suction ventilator (14), and the coal gas come out from coal gas suction ventilator (14) enters gas pressing cooled hydrogen purification device (15), coal gas is added to six atmospheric pressure, the vapor and carbon dioxide in coal gas become liquid and removed, and are left pure Hydrogen；If the temperature in reaction kettle (1) is more than setting high temperature value, computer controller can tune up vapor electric control valve (23), it allows more vapor to enter reaction kettle (1) to chemically react with the coal dust for being more than setting high temperature value, suspends discharging The electricity of electronic rotation valve (4) reduces the coal dust on recirculating fluidized bed (5), turns motorized adjustment air-valve (25) down；If reaction kettle (1) for the temperature in lower than setting low temperature value, computer controller can turn vapor electric control valve (23) down, and less water is allowed to steam Gas enters reaction kettle (1) and chemically reacts with the coal dust lower than setting low temperature value, and discharging electronic rotation valve (4) is re-energised Rotation increases the coal dust on recirculating fluidized bed (5), tunes up motorized adjustment air-valve (25), and more wind is allowed to support on fluidized bed (5) Coal dust firing.
