Cyclone preheater design for 5500 ton cement production line

Cyclone preheater is one of the core equipment in the new dry cement production process, which is responsible for many functions such as gas-solid dispersion, material heating, gas-solid separation, material transportation and some physical and chemical reactions.. Separation efficiency and resistance loss are two main performance indexes to be considered in the design of cyclone preheater.

WASTE HEAT RECOVERY POWER PLANTS IN CEMENT

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).
