Abstract:
A heat transfer and cooling system for a natural gas fueled, internal combustion engine driven co-generation unit utilizing recycled exhaust gas comprising:(a) a fluid system for cooling said internal combustion engine having a first loop containing a cooling fluid which fluidly communicates with the cooling ports of said internal combustion engine at a first inlet temperature and a first flow rate; and, a second loop containing a cooling fluid which fluidly communicates with cooling ports of at least one exhaust manifold of said internal combustion engine at a second inlet temperature and a second flow rate, wherein the cooling fluid exiting said first loop at a the first exit temperature and the cooling fluid exiting said second loop at the second exit temperature, converge in a confluence in at least one process heat exchanger; and (b) a co-generation process/utility heat loop containing a heat receiving medium in communication with said at least one process heat exchanger containing said confluence such that heat contained in said confluence from said cooling system is passed to the media of said co-generation process/utility heat loop.
