<p>PROBLEM TO BE SOLVED: To provide a fuel gas production system capable of increasing calorific value of generated gas and combustion stability without any heat exchanger or deaerator by furnishing a air heating furnace so as to preheat the air introducing into the gasification furnace by burning a part of generated gas feeding to a gas turbine. SOLUTION: This fuel gas production system consists of a gasification furnace 1 where fuel is partially oxidized with air to be gasified, a gas cooler 2 where the generated gas gasified in the gasification furnace 1 is cooled, a gas purifier 3 where the generated gas cooled in the gas cooler 2 is purified and the generated gas purified in the gas purifier 3 is fed into a gas turbine 4 and burned and, in addition, a hot air generator 8 where air feeding to a gasification furnace 1 is preheated by burning a part of generated gas to the gas turbine 4.</p> |
