The gasification reactor equipment which has the dust density measurement device, the automatic combustion control system and the exhaust gas treatment control unit of the generation gas of the gasification reactor

摘要

P To control a combustion treatment system and an exhaust gas treatment system of gasification furnace equipment by catching sudden change of char of a generated gas of a gasification furnace ON the basis of the change of a decreasing rate of light-receiving intensity of laser. PSOLUTION: As an index to catch the sudden change of char and the laser is applied to the generated gas of the gasification furnace by a laser analyzer 2 in a former stage of a combustion chamber 3, the decreasing rate of the light-receiving intensity of the received laser is converted into char concentration to be used as the index, a flow rate of the combustion air supplied to the combustion chamber 3 is continuously changed in response to the char concentration and the amount of chemical supplied by a chemical supplying device 19 is continuously changed by hydrogen chloride elimination control and sulfur oxide elimination control of the exhaust gas in response to a change rate of the char concentration.
