CN101709879A - System for deep cooling and waste heat

The smoke gas of which the dust is removed by an electrostatic dust remover is used for heating the cold water in the smoke gas deep cooler to recover the waste heat of the exhausted smoke, and the hot water at the outlet of the smoke gas deep cooler is transferred to the air heater for preheating the air, thereby increasing the temperature of the combustion-supporting air in the boiler; after the smoke gas passes through the smoke gas deep cooler, the smoke gas
