      A large proportion of CO 2 is produced by the worlds fossil fired thermal power plants; efforts to reduce these outputs are various and widespread. Almost all coal, nuclear, geothermal, solar thermal electric, and waste incineration plants, as well as many natural gas power plants are thermal. The vast use of present compression cooling machines is also responsible for an increasing peak demand of electrical power in summer which reaches already the capacity limit in some southern countries. Because most of the electrical power stems from fossil fired power plants this also increases the production of CO2 which is no longer acceptable.

Geothermal preheating in fossil-fired steam power plants. [Washington]: Dept. of Energy, Division of Geothermal Energy ; Springfield, Va.: For sale by the National Technical Information Service, A thermodynamic analysis of a hybrid fossil geothermal power plant in which the low-grade geothermal energy is used for preheating the feedwater in a fossil-fired steam power plant is presented.

By restricting the geofluid to sensible heat addition, the entropy production in this process can be reduced. Results of thermodynamic studies of geothermal steam power systems incorporating fossil-fired superheaters are reported. One- and two-stage systems are covered.

Realistic assumptions have been included to account for losses that may be incurred in actual plants. The systems are evaluated on the. Sincenovel solutions have been proposed to integrate the geothermal source with fossil-fired power plants, which have considerably higher efficiencies than geothermal power plants.

Geothermal heat can be used either for feed-water preheating in a conventional steam power plant, with an overall conversion efficiency exceeding 40%, or to Cited by: The thermodynamic basis for the design of geothermal power plants is at the heart of the book.

The Second Law is used extensively to assess the performance and guide the design of various types of geothermal energy conversion systems. Geothermal Preheating in Fossil-fired Steam Power Plants.

At the present time, geothermal generation is limited to areas of geothermal activity such as fumaroles, geysers and hot springs.consisting of fossil-fired plants and 26 nuclear plants. Typically, modern conventional steam power plants operate with a TH of about C ( F), yielding a maximum theoretical conver- sion efficiency of 61%.

Mechanical and other losses further reduce the efficiency to a practical limit of about 40%. Attempts to improve this efficiency level by increasing T have been hindered by severe mater- £1.

One is the Joule or Brayton cycle which is a gas turbine cycle and the other is Rankine cycle which is a steam turbine cycle.

The cycle which is the gas turbine power plant cycle is the topping cycle. It depicts the heat and work transfer process taking place in high temperature region. Purpose In thermal power plants, the primary purpose of a surface condenser is to condense the exhaust steam from a steam turbine to obtain maximum efficiency and also to convert the turbine exhaust steam into pure water (referred to as steam condensate) so that it may be reused in the steam generator or boiler as boiler feed water.
