Energy represents 20% to 40% of the total cost of cement production. The production of cement clinker from limestone and chalk by heating limestone to temperatures above 950°C is the main energy consuming process. Portland cement, the most widely used cement type, contains 95% cement clinker.
×33 Energy Saving Cement Rotary Kiln For Wet And Dry Cement Production Equipment Introduction: Cement rotary kiln refers to the rotating furnace pellets, and it belongs to the building materials equipment. According to the different processing materials, rotary kiln can be divided into cement kiln, metallurgy chemical kiln and lime kiln.
If no effective energy saving method is adopted and waste heat is fully utilized, the energy consumption will increase, in order to reduce the energy consumption of the cement plant, it is necessary to make full use of waste heat from the surface of the cement rotary kiln, collect waste heat with the help of waste heat ...
How to Save Energy in Lime Rotary Kiln (One) With the rapid development of the national economy, the demand for lime has increased significantly. However, the raw fuel for producing lime is also greatly increasing, especially for the fuel for burning lime (coal and combustible gas), and the fuel cost accounts for more than 70% of the total cost ...
The net heat use per tonne of quicklime varies by kiln design. Rotary kilns generally require more heat than shaft kilns. The heat use tends to increase as the degree of burning increases. [CLM BREF, EC, 2009, p. 242] The use of electricity varies from a low range of 5 to 15 kWh/tonne of lime for mixedfeed shaft

Since kiln energy consumption was 3276 kW, without this movement of the cooling gases, energy consumption would therefore have been 3961 kW. The maximum potential energy savings provided by the cooling gas heat recovery could be %, in this kiln. This energy saving action does not require any special investment, as occurs in other cases . It can be implemented just by adjusting the static .
