The cement calcining system mainly reduces energy consumption by saving coal and power. It is generally believed that in order to reduce energy consumption of the clinker production line, improvements should be made in the preheater outlet temperature, cooler outlet temperature, and clinker temperature out of the cooler.
Here, a novel lime calcination system with carrier gas (CO 2) heating and air cooling is proposed to avoid the mixing problem of the CO 2 and the flue gas. This system consists of a new shaft kiln with four processing zones and a furnace system, where fuel combustion, limestone reaction, and lime cooling are carried out separately.
Calcining – the kiln fuel is burned in the preheated air from the cooling zone and, as the limestone moves down the kiln, the heat turns the limestone into quicklime and carbon dioxide (CO 2 ).
taken during the initial start-up of the lime calcining system. The ductwork carrying the cooling air from the fan to the cooler actually divides the air into four individual streams as it enters the cooler. Each one of these four "mini-ducts" directs cooling air to one of the four cooling quadrants within the cooler and has its own
