Abstract |
|
Historically industries have shown an aversion towards extracting work from low temperature heat sources mainly because the Carnot efficiency with these sources comes out to be lower and on top of it, if one employs the traditional Rankine cycle with these low temperature heat sources the cycle efficiency, in most cases, boils down to a single digit value. But in the recent past many ingenious augmentations have been proposed in our approach of heat extraction which has provided us with a substantial scope of improvement in the cycle efficiency. The aim of this paper is to discuss some of these process side breakthroughs in the field of extracting work from low temperature heat sources. More specifically the paper will be focusing on Kalina cycle and Organic Rankine cycle which are the two most promising and commercially developed options available among all low temperature heat extraction cycles. |
