Document Type and Number:
Japanese Patent JP7309593
Kind Code:
B2
Abstract:
To improve an exhaust heat recovery rate and save energy in an exhaust heat recovery system for a gas compressor.SOLUTION: An exhaust heat recovery system includes: a gas compressor having a compressor body compressing gas and outputting compressed gas; and exhaust heat recovery device having an exhaust heat recovery heat exchanger and exhaust heat recovery liquid piping in which exhaust heat recovery water exchanging heat with the compressed gas in the heat exchanger flows. The compressor body and the exhaust heat recovery heat exchanger are connected by gas piping in which gas to be compressed flows. The exhaust heat recovery device includes: a temperature sensor disposed downstream of the exhaust heat recovery heat exchanger in the exhaust heat recovery liquid piping; a temperature regulating valve; and a temperature controller controlling an opening/closing angle of the temperature regulating valve in accordance with a temperature of the exhaust heat recovery water measured by the temperature sensor and a set recovery water temperature.SELECTED DRAWING: Figure 1
