Waste Heat Power Plant in Cement Plant
One cement plant customer needs waste heat recovery power plant in his project. In such a waste heat power plant, cement plant waste heat boilers are to be installed to provide the driving force.
Waste heat power plant for cement plants
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 (preheater exit gas) and cooler exhaust air. This heat can be used for electricity production. Power can be produced by using a steam cycle, an organic rankine cycle, or the KALINA process. The low temperature level of the waste heat in cement plants (200 – 400 °C) limits the efficiency to a maximum of 20 – 25%. However, 25 to 30% of plant's power demand can be met through generating power from waste heat.
Waste heat steam boiler can recycle heat for power in the cement plant. Many cement plants utilize the waste heat power plant for electricity generation. It has been reported that there are at least 33 cogeneration units in various cement plants with total capacity about 200 MW in Japan. In China about 24 kilns having capacity of 2000 ton per day and above have cogeneration units with supplementary fired boilers to meet about 22 – 36 kWh/t clinker.
