Turbine generator cycle for provision of heat to an external heat load

A steam turbine power plant comprising, in series, a steam generator element, a high pressure turbine element, a low pressure turbine element, a condenser element, a high pressure feedwater heater extracting steam from a predetermined location within said high pressure turbine element, a low pressure feedwater heater extracting steam from a predetermined location within said low pressure turbine element, said steam extracted from said high pressure turbine having associated therewith a heating capacity different from the heating capacity of said steam extracted from said low pressure turbine element,

• a closed loop flow arrangement disposed only in heat transfer relationship with said power plant to extract heat therefrom to supply a heat load, said flow arrangement confining and guiding a heat transfer medium therewithin,
• a first and a second heater element connected within said flow arrangement, said first heater element extracting heat from said power plant by extracting steam from said predetermined location within said low pressure turbine element and disposed in parallel with said low pressure feedwater heater, said second heater element extracting heat from said power plant by extracting steam from said predetermined location within said high pressure turbine element and disposed in parallel with said high pressure feedwater heater, said heater elements transferring said extracted heat to said heat transfer medium,
• a heat exchange element connected within said flow arrangement for exchanging said extracted heat in said heat transfer medium to said heat load, and,
• means for controlling the rate of flow of said heat transfer medium within said closed loop flow arrangement, the magnitude of said heat extracted from said power plant being directly controlled by said flow rate of said heat transfer medium.
