preheater for cement plant

Build-up of preheater tower

Preheater is mainly composed of cyclone barrel, air pipe, discharge pipe, decomposing furnace, wind lock valve and other parts. The high-temperature airflow in the kiln is used to adopt a multi-stage circulating suspension preheating method to fully exchange heat between the raw meal powder and the hot gas stream, complete the suspension preheating and partial decomposition of raw meals ...

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).

Customized Cement Kiln Heat Recovery Solutions. Every cement plant has unique characteristics – whether it is the type of fuel fired in the kiln, the number of preheater stages, utility incentives, cost of power – these are different at every plant. As a result, the system design needs to be customized to maximize the benefit for the plant.

Preheater Used in Rotary Kiln. For cement production line, there are many cement equipments among which cement preheater is included. Rotary kiln is used widely in cement plant, and we design and produce new-style rotary kiln with vertical preheater which takes use of the heat of the flue gas coming out from the kiln end to preheat the dolomite to 800℃ in the preheater.

The new CCX delivers cement plant owners greater opportunities to reduce initial installation expenses and improve plant operations. Leading the way as the next generation of top-stage cyclone technology, the CCX is designed to make the preheating process more economical. ABOUT THE AUTHOR: Ram Kumar Sridharan, Product Line Manager-Pyro, FL.

The modern cement plant incorporates a suspension preheater in the clinker production line to reduce energy consumption. Preheaters are a series of cyclone vessels and ducts that preheat the raw mix using the hot gases from the rotary kiln. Temperatures progressively increase as the kiln feed descends to the lower stages.

Cyclone preheaters are also called suspension preheaters. In the new dry process of cement manufacturing, the raw meal must be preheated in the preheater before entering the rotary kiln for calcining.The quality of the preheater in a cement plant directly affects the stability of calcining temperature and cement clinker quality in the kiln.

Most new cement plant is of this type. The principle is similar to that of the dry process preheater system but with the major addition of another burner, or precalciner. With the additional heat, about 85%-95% of the meal is decarbonated before it enters the kiln
