Steam Turbine Cogeneration

Steam turbines are widely used in most industrial facilities because steam is readily available and steam turbine is easy to operate and maintain. If designed properly, a steam turbine co-generation (producing heat and power simultaneously) system can increase energy efficiency, reduce air emissions and qualify the equipment for a Capital Cost tax Allowance. As a result, such a system benefits the stakeholders, the society and the environment. This paper describes briefly the types of steam turbine classified by their conditions of exhaust and review quickly the fundamentals related to steam and steam turbine. Then the authors will analyze a typical steam turbine co-generation system and give examples to illustrate the benefits of the System.
