摘要： PURPOSE:To contrive reduction of running cost by eliminating power consumption for making continuous driving of an exhausting motor-driven fan, by making forced discharge of exhaust gas continuously by driving a compressor by a gas turbine to be driven by the exhaust gas from a combustion chamber. CONSTITUTION:When a compressor 6 interlocked and connected with a gas turbine 7 by a starter 13 is once started by supplying fuel and air to a combustion chamber 4, the turbine 7 is driven and the compressor 6 is driven continuously. Then driving of the turbine 7 and the compressor 6 based on exhaust gas from the combustion chamber 4 is kept maintained and the exhaust gas from the turbine 7 is discharged out of a system continuously. Then as a heater can be made to actuate continuously without being accompanied by power consumption except for a starting time, running cost as a whole of equipment can be reduced drastically.
