The cyclone preheater, also called cement preheater, suspension preheater, is a kind of preheater in cement plant.As the core equipment of dry method cement production line, cyclone preheater use suspension preheating to preheat and partly decompose the cementraw mix, shorten the length of rotary kiln, fully mix raw mix and hot air in the kiln, increase heat exchange rate, which promote the
Preheater Of Cement Plant. The core of the pyroprocess of each modern cement kiln is the preheater Most substantial thermochemical reactions of the cement process occur in the riser ducts and in the calciners and certainly in the sintering zone of the kiln Modern suspension preheater kilns usually have 1 or 2 in a few cases also 3 strings with 4 or 5 stages
The more stages are used, the more efficient the preheater is. But each stage increases the pressure drop across which the kiln fan must work, and with more than six stages, the fan power requirement is prohibitive. However, in practice waste heat is needed for the

S. Laroche, in Steam Generators for Nuclear Power Plants, 2017. 4.2.2.3 Preheater thermal plate leakage. The integral preheater with crossflow usually includes a thermal plate that separates the feedwater from the recirculating flow from the downcomer flow entering the tube bundle. There is a small clearance gap between the tubes and the thermal plate and leakage is possible through this gap.

More than 30 raw materials are known to be used in the manufacture of portland cement, and these
It is also important to note that natural gas is the most common fuel used to start up the kiln and preheater, before introducing the solid fuels. Another common source of fire in cement plants is the use of rubber conveyor belts to move hot clinker from the clinker cooler to the clinker storage silos.
