Title:
GAS SUPPLY DEVICE AND EXHAUST GAS POWER GENERATION SYSTEM
Document Type and Number:
Japanese Patent JP2011112030
Kind Code:
A
Abstract:

To provide a gas supply device suppressing a pressure drop in a heat treatment furnace; and an exhaust gas power generation system.

The gas supply device 4 includes a first passage 11 for connecting the heat treatment furnace 2 and a power generator 3; a pressure control valve 21 disposed in the first passage 11 and controlling the pressure of exhaust gas flowing through the first passage 11; and a furnace pressure gauge 51 for measuring the pressure in the heat treatment furnace 2. When the pressure in the heat treatment furnace 2 measured by the furnace pressure gauge 51 is below a predetermined value, the pressure control valve 21 controls the pressure of the exhaust gas in the first passage 11 so as to increase the pressure of the exhaust gas.
