Energy audit and waste heat recovery from kiln hot shell

Oct 01, 2020· Selection of refractory materials as per the operating condition of rotary kiln can help in optimization of shell temperature profile of cement kilns. In this paper, various profile sets of energy transfer are analyzed between hot air and cold water used in a heat exchanger designed for kiln shell heat recovery.

Waste Heat Recovery from Cement Kiln Radiant Cooling

These rotary kiln systems have to be maintained at high temperatures of 900 °C 1500 °C. More than 40% of the input energy is lost through the kiln shell, cooler stacks and kiln exhaust gases. When all the heat losses are considered, the kiln operates at a low efficiency of around 46%.

Everything You Need to Know on Rotary Kiln Refractory

This can be done by picking a spot on the rotary kiln shell, and holding a temperature gun in place. As the rotary kiln rotates, that spot should read the same temperature for the entire circumference of the shell. For example, a temperature reading of 400º, 400º, 700º, 400º would likely indicate a failure in refractory. Left untreated

As the rotary kiln rotates, that spot should be the same temperature for the entire circumference of the shell. There would be trouble if the temperature reading was 400º, 400º, 700º, 400º. A hotspot on the shell of the rotary kiln indicates

Lime Recovery Kiln Refractory Products Resco Products

The burning zone is the hottest location in a lime recovery kiln. Here dissociation of calcium carbonate occurs at high temperatures, producing the lime product. Depending on the process, the burning temperature can vary from below 2000°F (1100°C) to nearly 2500°F (1370°C), and this will dictate refractory selection for the burning zone.
