Technology: A pre-heater is a counter current flow heat exchanger consists of number of cyclones to transfer heat from gases to the material In the cyclone of pre heater there are two parts The upper part called riser duct (raw meal) is meant for heat transfer, whereas the cone and cylindrical part acts as ,
preheater used to be 500 to 550 mmwg Any increase in number of stages resulted in additional pressure drop which unfavorably offset gain in fuel efficiency Therefore cement industry continued for quite some time with 4 stage preheaters till cyclones of low pressure design were developed Attention

cyclone preheater (4 to 6 stages) or a precalciner kiln, or more rarely, to a long dry kiln Kilns with preheaters are more energy efficient and are significantly shorter (40 – 100 m) Dry process kilns are the vast majority of existing kilns Production capacity may vary between 500 and >10,000 t/d
The calcineous raw meal is passed through a set of pre-heater cyclones (depending on pre-heater assembly) before it is sent to the calciner In the pre-heater section, the raw meal is pre-heated to around calcination temperature by hot gases coming from the calciner The operation of cement pre-heater is similar to that of a conventional cyclone
Such heat as escapes the preheater is used to heat the rawmill The concept of the suspension preheater gradually emerged when, from the 1920s onward, some kilns started to be fitted with cyclones to remove most of the dust from kiln exhausts, and to return it to the kiln
In cement plant the exit gases from Rotary kilns, pre-heater and Calciners are used to heat the incoming feed material and gases are cooler around 300 to 350 Â°C in 4 stage pre-heater and then exhausted to the atmosphere SYSTEM DESCRIPTION AND DATA SOURCE The cement industry has an important role in the economy based on its production
