METHANOL CHEMICALLY INTERCOOLING GAS TURBINE CYCLE WITH THE RECOVERY MIDDLE-LOW TEMPERATURE HEAT

In this paper, we have proposed a methanol chemical intercooling gas turbine cycle with the combination of middle-low temperature heat on the basis of a new principle of fuel releasing chemical energy, and the reasons of the reduction of exergy loss in methanol combustion and the enhancement of the availability of low level energy have been investigated with the aid of energy utilization diagraph (EUD) methodology. In addition, we have studied the thermodynamic performance of the proposed cycle. This paper may provide the basis for the further investigation of the new principle of fuel releasing chemical energy and the creation of novel thermodynamic cycle with the recovery of middle-low temperature heat.
