Abstract

The method of hot restarting a power generating steam installation or plant, in which the temperature of the steam entering the turbine must closely approximate the temperature of the critical parts of the turbine, including said power plant. steam a water steam boiler provided with a radiant heat absorbing part or section including the hearth tubes, and a convection heat absorbing part or section including a first reheater (superheater) and an intermediate reheater, and including the plant also a steam turbine equipped with a high pressure stage and a low pressure stage, said intermediate superheater being functionally interconnected between said high and low pressure stages, besides establishing a working fluid circulation current through said tubes of the household with an expense or enough flow to cool said tubes preventing them from suffering damage by heat, heat is applied to said circulation stream until a mixture of water and circulating vapor is produced, and the vapor of said mixture is separated from the water; said method being characterized by the steps of: circulating a first part of said separate steam, bypassing said first superheater and said high pressure turbine stage, said intermediate superheater and up to the entrance of said low pressure turbine stage ; circulating a second part of said steam separated by said first reheater, bypass with said high pressure turbine stage, by said intermediate reheater and up to the entrance of said low pressure turbine stage; circulating a third part of said separate steam from said first reheater to the inlet of said high pressure turbine stage; adjust the temperature of the steam that passes to said low pressure turbine and that of the steam that passes to said high pressure turbine; respectively, adapting them to the temperature of the respective critical turbine parts, by altering the proportion of heat absorbed in said radiant heat absorbent section relative to that absorbed in said convection heat absorbing section, and by altering the input of heat to said total circulation current; and passing said first and second steam portions and said third steam portion, respectively, through said low pressure turbine stage and said high pressure turbine stage, to start and rotate the turbines.
