MoreHeat pipe type flue gas-soft water heat exchanger was used to recover waste heat from tail gas of lime rotary kiln. That is to say, a heat pipe type flue gas-soft water heat exchanger is set up on the tail pipe line between the preheater and the dust collector of rotary kiln. Soft water is used as the heat medium to heat the tail gas of rotary

MoreOne of the effective methods of improving the efficiency of a rotary kiln is through waste heat recovery around the kiln surface. The radiant panel can be installed along the kiln that can harvest the heat dissipated through the kiln surface. The radiant panels designed and fabricated at Oorja have a coolant running through them.

MoreOne of the effective methods of improving the efficiency of a rotary kiln is through waste heat recovery around the kiln surface. The radiant panel can be installed along the kiln that can harvest the heat dissipated through the kiln surface. The radiant panels designed and fabricated at Oorja have a coolant running through them.
MoreHeat exchange in a rotary kiln may be by conduction, convection and radiation, in descending order of efficiency. In low-temperature processes, and in the cooler parts of long kilns lacking preheaters, the kiln is often furnished with internal heat exchangers to encourage heat exchange between the
MoreHeat setting involves bonding a heat resistant core mineral with another, less heat resistant coating material. Unlike an unheated coating process, here, a rotary kiln heats the coating material to just below liquefaction point, allowing it to coat the heat resistant core more evenly and more securely.
MoreThe rotary kiln is also capable accepting feedstocks of varying moisture content and particle sizes, reducing the need for pre-treatment in many cases; from barrels to material fines, shredded waste, and everything in between, rotary kiln incinerators accept it all.
