rotary kilns waste heat recovery

Carbon rotary kiln waste heat boilers use the waste heat of the exhaust gas from carbon rotary kiln or tank carbon calciner, to produce the superheated steam for turbonator or life. After calcination, the gas has high temperature (900 to 1100 degrees Celsius), low dust content (~ 5g / Nm3), and a higher content of SOin the flue gas, based on ...
