PURPOSE:To make the air supply with good load responsiveness and no fluctuation possible, by keeping the discharge air pressure of the compressor of a turbo compressor constant under the feedback control by operating a by-pass valve, while keeping the combustion control of a sub-combustion furnace under the feed-forward control based on a program. CONSTITUTION:In case of the regular operation of a system, the combustion volume control of a combustion furnace (28) is kept constant under the feedback control of the constant discharge air pressure compressor (3b) of a turbo compressor, by opening an atmospheric open valve (12) to its fuel or small opening. In case of the load fluctuation of the system the discharge air pressure of the compressor (3b) of the turbo compressor is always kept constant by keeping the constant feedback control of the discharge air pressure of the compressor (3b) by operating the atmospheric open valve (12), while keeping the combustion control of a sub-combustion furnace under the feed-forward control based on a program. |
