<p><P>PROBLEM TO BE SOLVED: To provide a heat recovering method from exhaust gas, and its device for providing high dust removing efficiency with a small pressure loss in dust removing treatment performed before heat recovery by a boiler, and efficiently recovering heat energy by generating steam having high temperatures and pressure without accelerating corrosion of a heat transfer pipe in the heat recovery by the boiler. <P>SOLUTION: This heat recovering method recovers heat by the boiler after removing dust at high temperature from gas exhausted from incineration equipment or gasification equipment of waste, and uses a dust removing assistant for generating a compound melting in gas by reacting with the dust removing assistant melting in the gas and/or a component in the gas when performing the dust removing treatment by introducing the exhaust gas to a high temperature dust removing device 20 before the heat recovery by the boiler 30. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
