A module for heat recovery from exhausted flue gas in a steam generator is described comprising a flue gas outlet conduit defining a flow path for flue gas from a flue gas outlet of a steam generator to a flue gas conduit junction; a first flue gas conduit defining a flow path for flue gas from the junction to a first air heater; a second flue gas conduit defining a flow path for flue gas from the junction to at least one high pressure and at least one low pressure process liquid economiser. A steam generator using the module, a method implementing the flow principles embodied in such a module, and a method of incorporation of such a module into a steam generator, especially by retrofit, are also described. |
