Nice econimic technology , but how much time it needs to be fully integrated in the market . . .and its environemental . . . heat combination system. . . , it's used in power plants here , they use the heat of the exhaust to heat the fuel before entering the burner . . . . . . .
I think that that's what manufacturer should head for , comibing energy in 1 plant which results in more efficiency , less global worming , and economy
The process in the link Peter posted is for co-generation. It some cases it is called CHP, or Combined Heat Power. The micro-turbine is a miniature jet engine that burns natural gas. The turbine can turn an electrical generator to produce electricity or something else.
The heat produced by the combustion process can be used for space heating, desiccant regeneration (to dry out the desiccant) or to fire an absorber for cooling.
Several of these have been installed with relatively good operation.
The efficiency of the cycle is dependent on the requirements, i.e., how much heating is required, how much cooling, how much electricity is needed, etc.
This is a very interesting technology.
Here are some additional links for review:
