Description
Известны устройства дл прогрева перегретым паром корпусов паровых турбин при их пуске и остановке.Known devices for heating superheated steam of steam turbine shells when they start and stop.
В отличие от этих устройств дл получени более равномерного пол температур по всему корпусу турбины при прогреве предлагаетс в нижней части корпуса установить устройство дл душировани внутренней поверхности нижней части корпуса турбины. Душ из перегретого пара более интенсивно прогревает стенку корпуса.In contrast to these devices, in order to obtain a more uniform temperature field over the entire turbine casing during heating, it is proposed to install a device in the lower part of the body for suffocating the inner surface of the lower part of the turbine body. A superheated steam shower warms the body wall more intensively.
Подача пара в устройство может быть регулируема дросселем, управл емым датчиками температур, установленными в верхней , и нижней част х корпуса.The steam supply to the device can be regulated by a throttle controlled by temperature sensors installed in the upper and lower parts of the housing.
На фиг. 1 и 2 дана схема устройства.FIG. 1 and 2 given the scheme of the device.
В нижней половине корпуса турбины 1 установлен дугообразный коллектор 2 с парораспределительными трубами 3, имеющими отверсти на нижней поверхности 4 дл душировани паром внутренней поверхности стенки 5 нижней половины корпуса /. Дроссель 6, установленный на паропроводе 7, управл етс датчиками температур, размеш ,енными в верхней и нижней част х корпуса турбины.In the lower half of the turbine casing 1, an arcuate collector 2 is installed with steam distribution pipes 3 having openings on the bottom surface 4 for steam blowing of the inner surface of the wall 5 of the lower half of the casing. The throttle 6 mounted on the steam line 7 is controlled by temperature sensors placed in the upper and lower parts of the turbine housing.
Такое выполнение устройства способствует получению равномерного пол температур по всему корпусу и повышает надежпость пуска и остановки, что подтверждаетс экспериментальными данными, полученными при прогреве корпусов турбин, работаюш,их с высокими параметрами пара.Such an embodiment of the device contributes to obtaining a uniform floor temperature throughout the hull and increases the reliability of starting and stopping, which is confirmed by experimental data obtained during the heating of the turbine hulls, working with their high steam parameters.
