Abstract Exhaust gas temperature can be lowered, and therewith the coal consumption, by installing a waste heat recovery appliance in a boiler's flue gas duct. Taking a 670 t/h boiler as an example, the paper presents the functional relationship between the recovery appliance's optimal heating area (optimum design) and the steel to coal price ratio, service life, set's annual power generation performance, after having calculated 10 versions of heat exchange surfaces, cycle performance and techno economic merits with object of obtaining maximal capital return.
