Abstract

As distributed generation becomes more reliable and economically feasible, it is expected that a higher application of the distributed generation such as Micro Gas Turbine Power system would be interconnected to the existing grids. This paper describes the results for the mechanical and environmental tests of pretreatment system for Livestock bio-energy Micro Gas Turbine (MGT) Combined Heat & power. It is very important for bio-energy pretreatment system to design MGT power generation. Especially, mechanical and corrosion characteristics of H2S removal system make differences between parent and weldment material, notch existence/non-existence and air/H2S conditions. As a result, the life of pipelines needs to be maintained and fit for the operating period. Based on actual situations, the tension test of pipe welding-parts is carried out varying the exposure time to hydrogen sulfide and a fatigue resistance test is also performed inserting a notch into the pipe welding part, being exposed to the hydrogen sulfide environment_x000D_ for 180, 360, 540, 720 hours.
