Abstract:

Exhaust system and cooling system for the heat conduction oil of the combustion beam in the double beam lime kiln were re\|designed.The waste heat and heat energy of the heat conduction oil are recycled.By installing the turbine and electromotor on the same side,draught fan is directly driven by the  recycled heat through turbine.This paper analyses the economic effects of such  design and indicates that every kiln can save 1.4 million  Yuan annually by power saving and the recoveryrate of waste heat is higher due to the omitting of  intermediate energy conversion process.
