UTILIZATION OF WASTE HEAT FROM WASTE HEAT RECOVERY BOILER THROUGH A WATER TUBE HEAT EXCHANGER

Rotary kiln the there is lots of amount of heat is generated during the combustion of coal and that heat to be utilized before throwing it into the environment. Waste heat recovery boiler is quite suitable to utilize that heat from kiln but there is region in boiler where the heat is not utilized efficiently. So, the approach should be made for same purpose. But it is necessary to use waste heat in such a form to make system efficient and productive. Then we have decided to design the heat exchanger for that particular region. But condensate extraction pump (CEP) and deaerator works on low temperature and pressure, so it is necessary to design heat exchanger in same way. Water will be feed through condensate extraction pump (CEP) and condensate water heated in heat exchanger and then goes to deaerator. This water will reduce the fuel consumption and will make system cost effective.
