CONTAINERIZED7.8 MW POWER PLANT CONCEPTAPPLICATION CASE STUDIES FOR A PRE-ENGINEEREDGAS TURBINE CHP PLANT

摘要

Combined Heat and Power (CHP) is a highly efficient way to generate power and heat. Byrnlinking a gas turbine with a heat recovery steam generator (HRSG) up to 90% of the fuelrnenergy can be converted into electric power and useful heat. This reduces Greenhouse Gasrn(GHG) emissions in many cases by more than 30%.rnSiemens Power Generation (PG) has developed a CHP plant concept for 5-13 MW gasrnturbines in order to reflect the requirements of this market segment. In the first stage therndevelopment has been based on the Siemens’ SGT-300 industrial gas turbine which isrndesigned for highly efficient combined heat and power generation. A benchmark with otherrnindustrial goods has shown potential improvements by packaging the power plant systemsrninto modular units. These modules will be pre-engineered and packaged into containers whichrnwill only be interconnected on the construction site.rnInvestigations have been made as to how to improve the economic value for the end user ofrnsuch a plant. Different aspects considering construction and erection time, lifecycle cost andrnoperational flexibility have been analyzed. This has formed the basis for the productrnspecification of the containerized power plant.rnThis paper will discuss this new power plant concept by means of case studies for the mainrnCHP applications. The main results of the investigation will be shown.
