Abstract |
Micro gas turbine(MGT) has received attention recently as a small-scale dis-tributed power source. Due to many advantages such as their small size, low maintenance cost and minimal vibrations during operation, they are expected to become widespread in a wide range of applications. The exhaust heat emitted by the MGT is in the form of an ex-haust gas that is about 270℃ which is an extremely clean gas. Korea Gas Corporation (KOGAS) has researched performance characteristics of a cogeneration system combining 28 kW class MGT and 13 USRT class absorption hot and chilled water generator in the local condition. The present results of this study can be summarized as follows: (1)in heating mode, the total efficiency of cogen. system is about 65% and heating capacity is 33kW at 25 kW MGP power (2)in cooling mode, COP is about 0.6 at 22kW MGT power. |
