Abstract

1. Одноцилиндровая теплофикационная турбина для парогазовой установки с петлевой схемой движения пара в цилиндре, подводом пара высокого давления, подводом пара низкого давления и двумя регулируемыми отопительными отборами пара, отличающаяся тем, что пар низкого давления подводится с повышенным до производственного отбора давлением в камеру межкорпусного пространства, в которую после разворота потока на 180° поступает пар прошедший ступени части высокого давления расположенные во внутреннем корпусе, тем самым организовывая петлевую схему движения пара в цилиндре, подвод и нерегулируемый отбор пара из камеры межкорпусного пространства, а также единственно возможную для обеспечения прочностной и вибрационной надежности конструкцию одноцилиндровой турбины для парогазовой установки мощностью от 60 до 120 МВт с более чем двумя регулируемыми отборами пара.2. Одноцилиндровая теплофикационная турбина для парогазовой установки по п.1, отличающаяся тем, что за камерой межкорпусного пространства содержится цилиндрическая регулирующая диафрагма производственного отбора, выполненная конструктивно заодно с обоймой ступеней отсека, следующего за камерой межкорпусного пространства для организации из нее производственного отбора пара с регулируемым давлением.1. Single-cylinder cogeneration turbine for a combined-cycle plant with a loop circuit for steam in the cylinder, high-pressure steam supply, low-pressure steam supply and two adjustable heating steam extraction, characterized in that the low-pressure steam is supplied with increased pressure to the production chamber to the inter-chamber chamber , into which, after a 180 ° turn of the flow, steam passes through the stages of the high-pressure part located in the inner casing, thereby organizing a loop with the flow diagram of steam in the cylinder, the supply and uncontrolled extraction of steam from the chamber of the interbody space, as well as the design of a single-cylinder turbine for a combined-cycle plant with a capacity of 60 to 120 MW with more than two adjustable steam withdrawals, which is the only possible to ensure strength and vibration reliability. A single-cylinder cogeneration turbine for a combined-cycle plant according to claim 1, characterized in that a cylindrical regulating diaphragm for production selection is provided behind the inter-chamber chamber, structurally integral with the clip of the steps of the compartment following the inter-chamber chamber for organizing industrial production of steam with controlled pressure from it.
