GAS SUPPLY DEVICE AND EXHAUST GAS POWER GENERATION SYSTEM

摘要

Disclosed is a gas supply device (4) provided with a first passage (11) which connects a heat-treating furnace (2) to a power generation device (3), a pressure control valve (21) which is disposed in the first passage (11) and which controls the pressure of exhaust gas passing through the first passage (11), and a furnace pressure gauge (51) which measures the pressure within the heat-treating furnace (2). Further, the pressure control valve (21) controls the pressure of exhaust gas so that the pressure of exhaust gas within the first passage (11) is increased when the pressure within the heat-treating furnace (2) measured by the furnace pressure gauge (51) is less than a predetermined value.
