waste heat gases and the economics involved. Large quantity of hot flue gases is generated from Boilers, Kilns, Ovens and Furnaces. If some of this waste heat could be recovered, a considerable amount of primary fuel could be saved. The energy lost in waste gases cannot be fully recovered. Waste heat Recovery means allowing the waste

Waste Heat Recovery in Cement plant - IJERT

Waste heat from cement kilns is usually used for drying of raw materials and fuel. Depending on the humidity of the raw materials and the cooler technology, additional waste heat is available from the kiln gases (pre-heater exit gas) and cooler exhaust air. This heat can be used for steam and electric power production.Waste heat recovery from
