Abstract

Способ работы тепловой электрической станции, по которому вырабатываемый в котле пар подают в турбину, отработавший в турбине пар конденсируют в конденсаторе, основной конденсат турбины и питательную воду перед подачей в котел нагревают в регенеративных подогревателях, из регенеративных подогревателей отводят паровоздушную смесь, отличающийся тем, что паровоздушную смесь из регенеративных подогревателей отводят отдельным пароструйным эжектором, перед подачей в пароструйный эжектор охлаждают в охладителе паровоздушной смеси редуцированным газом, который подают в горелки котла, а конденсат пара из охладителя паровоздушной смеси отводят в конденсатор.The method of operation of the thermal power plant, in which the steam generated in the boiler is supplied to the turbine, the steam spent in the turbine is condensed in the condenser, the main condensate of the turbine and feed water are heated in regenerative heaters before being fed to the boiler, steam-air mixture is removed from the regenerative heaters, characterized in that the steam-air mixture from regenerative heaters is diverted by a separate steam-jet ejector, before being fed to the steam-jet ejector, it is cooled in a cooler of the steam-air mixture of reduction gas, which is fed into the burners of the boiler, and steam condensate from the cooler of the vapor-air mixture is discharged to the condenser.
