CO2 Emissions Profile of the U.S. Cement Industry

Total energy consumption in the U.S. cement industry exhibited a decline between 1970 and the early 1990s, before showing an annual average increase of 4.5% between 1992 and 199913. Some of the decrease in energy consumption through the early 1990s can be attributed to the conversion from the wet process of clinker making to the dry process.

WASTE HEAT RECOVERY POWER PLANTS IN CEMENT INDUSTRY

In a cement plant, nearly 35% heat is lost, primarily from the preheater and cooler waste gases. This corresponds to around 70 to 75 MW of thermal energy. This energy can be tapped by installing a Waste Heat Recovery Power Plant (WHRPP). Size of WHRPP is influenced by the moisture content present in raw material and fuel (coal).
