Waste heat recovery technologies Generally, there are two sources of waste heat available in a clinker production line: i) waste heat recovery from hot gases and ii) radiant heat loss from the kiln surface. One of the most effective and simple waste heat recovery methods is the preheating of the raw material prior to it being fed into the kiln.
This boiler (for short AQC boiler), along with the Waste Heat Boiler for kiln rear preheater in the cement production line (for short SP boiler) forms the waste heat recovery system. With the development of the calcination technology of the cement clinker, the energy conservation in cement industry has got a great improvement.

Waste heat recovery is a way to lower electricity costs, thus strengthening the producer's position in the international market. In recent years, an increasing number of cement plants have increased their interest in waste heat recovery (WHR).
Waste Heat Recovery Systems (WHR) utilize the heat in industrial waste gases for the generation of electrical power. WHR Systems are common in cement and lime plants and other pyroprocess industries where Rotary Kilns are used and the price and reliability of grid power supply make the investment economically feasible.
As an example, for a typical cement plant producing 5,000 tons per day, a waste heat recovery system can reliably supply about a third of the plant's power needs. Based on an average electric grid price of 0.12 USD/kWh and a cost of operating a cogeneration unit at 0.01 USD/kWh, the plant stands to save a massive USD 6 million a year.
