Analyzing The Elements Affect The Economical Efficiency Of Fuel Gas & Steam Combined Cycle System Units

Fuel gas & steam combined cycle system can realize the gradient utilization of chemical energy to increase the efficiency of the system cycling.With the our state's energy policy turned more rational and scientific gradually in recent years,due to its high efficiency,construction duration short,easy adjust the peak operation and satisfy environmental friendly requirement to different counties around the world,this Fuel gas & steam combined cycle system be widely used and highly praised now.The developing of the Fuel gas & steam combined cycle system mostly rely on the development fundamental theories of engineering technology and thermodynamics field.Put forward new type thermodynamics system often be restricted by its economical efficiency and environmental protection both sides.At present,the goal for such combined cycle is high parameter,high performance,high efficiency,large scale and low pollution,at the same time we aim at develop and using newly developed clean energy in such cycling technology.Through disusing and researching to the Fuel gas & steam combined cycle system to point out how important role the Gas turbine played in such system which has great influence on economical efficiency and reliability.Increasing original temperature of fuel gas,improving Gas compressor‘s character,enhancing the cooling system efficiency also more important.Meanwhile,such as the other equipments ‘character,type of the fuel,exhaust temperature and ambiance condition these factors can not be ignored.And put forward some countermeasures about how to optimize different systems and hoe to improve this cycling system's characteristic during designing and operating procedure in this paper.In this paper,through acknowledge the developing trend and current status of Fuel gas & steam combined cycle system,analyzed developing trend and current status of such units used in our country,we can understand the Fuel gas & steam combined cycle system is power generate device which has a potential developing prospect and remarkable advantaged.With develop of reform of power system around the world,establishing new power market,enhancing environmental consciousness those accelerate the developing steps of Fuel gas & steam combined cycle system.In 21 th century,we can say Fuel gas & steam combined cycle system will be a leading role predominance in power generation field.Mainly analyze the economical efficiency of Fuel gas & steam combined cycle system units of Baogang energy supply plant in the paper.The purpose is find the reasons those affect the economical efficiency of this kind of system and get countermeasures to solve these problems and have a conclusion about it.From analyzing the components of fuel gas to indicate its influence to combined cycle system economical efficiency and exhaust temperature limitation and get the conclusion finding the countermeasures to solve these problems.
