PURPOSE:To precisely control the rate of air to the titled combustor by a simple control, by changing the rate of combustion air by increasing and decreasing in proportion to the difference of temperature between the temperature on the exhaust side and that on the intake side. CONSTITUTION:A temperature sensor 9 to detect the temperature of exhaust gas is provided in the position in an exhaust gas duct 8 where the exhaust gas after combustion passes through, while a temperature sensor 10 is detect the temperature on the air intake side is provided in a position in the combustion liner 1 where the intake air passes through. These temperature sensors 9 and 10 are connected to a control box 11, into which the detected temperatures by both sensors 9 and 10 are put, and the difference of temperature is calculated. With this output, the turning speed of a fan motor M for exhaust gas is automatically controlled by increasing and decreasing, by the intermediary of a controller 12 for the fan motor M for exhaust gas, so that the rate of combustion air can be changed in proportion to the difference of temperature between the temperature on the exhaust side and that on the intake side. |
