The co-generation facilities have maximal thermal efficiency. In the case of the Russian Federation, for the power production industry, the development of the co-generation combined cycle facilities (CCGT-CHP) is especially urgent. The CCGT-CHP daily load schedule requires the demand of both electricity and heat, and the heat demand depends only upon the ambient air temperature. The gas turbine power reduction and the subsequent steam turbine power reduction during the electric load drop down are limited by the necessity to maintain the steam flow to district water heater to supply heat power. Methane steam reforming allows the recovery of the excess steam heat in the form of synthetic gas together with the CCGT-CHP electric power reduction. This paper considers three versions of the CCGT-CHP steam use in the Methane reforming: Bleeding steam supply, throttling of the heat recovery steam generator exit steam and the supply of this steam to the steam production in a steam transformer. Steam Methane reforming allows a reduction in the steam turbine supply power of 25% during the electric system power drop down. In the daytime, during the maximal system load, the produced synthetic gas is used and it is necessary to use the peak load gas turbine, which allows a 23% electric power increase. Energy storage by steam Methane reforming increases the contribution margin by 2.9%.

The authors of this article already presented reports and publications to the attention of public at large [1][2][3][4][5], in which the specific features of steam turbines intended for use in advanced projects of combined cycle power plants (CCPs) were considered. We also gave a detailed description of the projects of prospec tive steam turbine that subsequently became real projects of cogeneration steam turbines for cogenera tion stations (CSs) and district power stations under construction. In [6][7][8][9][10], the specific features of steam turbine designs, layout solutions, and basic process circuits of the turbine units developed by the Ural Tur bine Works (UTZ) for CCPs were shown. In [4], it was pointed out that, in order to support the investment program aimed at development of the Russian power industry [11,12] with relevant equipment, the Minis try of Power and Industry should work out and approve a series of standard sizes of modules comprising a gas turbine unit (GTU), a heat recovery boiler (HRB), and a steam turbine unit (STU) for construction of CCPs. This will make it possible not only to shorten the time taken to approve and implement power sta tion construction projects, but also to reduce the cus tomers' costs spent for procuring dedicated equipment manufactured under a single order.We also pointed to the need to approve a series of standard sizes of main power generating equipment, as a result of which Russian manufacturers will be able to reduce production costs and strongly compete with foreign vendors, and the personnel of power generat ing enterprises will obtain modern serially produced and well elaborated equipment [4].In each new project of a turbine unit intended to serve as the steam part of a CCP, modern design and technological proposals were applied, the use of which makes it possible to solve a whole set of technical eco nomic, schematic, layout, and operational tasks with achieving high indicators of reliability and repairabil ity of main and auxiliary power equipment.In this article we would like to emphasize the most interesting and innovative solutions adopted in these projects and to show the development of some ideas and components from the first projects to subsequent ones. THE T 53/67 8.0 STEAM TURBINE FOR THE PGU 230 COMBINED CYCLE PLANTThe T 53/67 8.0 cogeneration steam turbine has been in operation since 2008 as part of the CCP installed at the Minsk TETs 3 cogeneration station, which comprises a 160 MW GT13E2 gas turbine pro duced by Alstom and a heat recovery boiler produced in Slovakia.The T 53/67 8.0 turbine is a two cylinder machine developed on the basis of a serially pro duced Tp 115/125 12.8 1 turbine. The design of the T 53/67 8.0 turbine incorporates both well elabo rated solutions and fundamentally new ones, the latter connected primary with the fact that this turbine was designed to operate as part of a CCP [6].The use of a throttle steam admission system in the turbine generated the need to design a new external valve cluster. Such a solution made it poss...

Combined cycle gas turbine cogeneration power plants provide maximal thermal efficiency. The facility thermal load depends upon ambient conditions and it may limit its unloading degree, or control range. Energy accumulation extends the control range by the energy storing during the power excess period and the energy discharge during the high consumption period. This paper considers two accumulation technologies, with the steam methane reforming and with hydrogen storage by using electrolyzer and fuel cell. In steam methane reforming technology a part of heat recovery steam generator steam passes to the synthetic gas production and reduces the electric power production during the low load periods. During the peak load periods, the synthetic gas is burned in combined cycle gas turbine and peak load gas turbine combustors. In hydrogen accumulation technology the excessive power produces hydrogen in an electrolyzer, which is stored and used during the peak load periods in fuel cells for additional electricity production. The simulation was carried out in the Aspen Plus software, the thermo-physical fluid properties were determined using the Peng-Robinson state equation. Application of the steam methane reforming accumulation technology increases the facility contribution margin by 2.6%, the hydrogen accumulation technology reduces this margin by 0.1%.
