54 Russian-made fast-built GTPPs

The modern energy market requires flexible solutions in conditions of capacity shortage, the risk of emergency situations or the need for rapid commissioning of generating capacities. ODK Engineering (part of Rostec's United Engine Corporation) develops and implements fast-erecting GTPPs that combine high power, mobility and reliability. In many regions of the country, due to rapidly growing demand for electricity, power systems are operating with increased load. It is often not possible to eliminate power shortages by building traditional power plants of large capacity due to the long lead times for their construction and commissioning. One of the real ways to solve this problem is the use of fast-built GTPPs for distributed power generation and their operation as part of power systems.

The equipment is delivered to customers in a state of maximum factory readiness, while the commissioning time is shortened.

 

56 Potential of TPP reconstruction with CCGTs in the Russian Federation

Increasing the efficiency of power plants today is possible both through the development of new turbine units and modernization of outdated facilities for power generation. The use of CCGT to improve energy efficiency is an economically feasible solution.

In their time (1960-70s) scientists of the Department of Turbine Engineering of the Leningrad Polytechnic Institute, in particular, Professor L.V. Arseniev, Associate Professors E.A. Khodak and G.A. Romakhova, were engaged in the development of the basics of the theory of combined cycle plants. Unfortunately, due to the low cost of hydrocarbon fuel in the USSR, the results of the work were not put into practice.

In the world practice during the introduction of CCGT in recent years it was possible to achieve quite high efficiency – more than 64%, for example, at Keadby-2 power plant in Great Britain. The article gives a brief overview of the world's leading practices in the field of construction and research in the field of CCGT.

In our country the modernization of existing domestically produced steam turbines by building them with gas turbines and HRSGs is very urgent. This significantly reduces the cost of the project compared to the construction of a completely new power unit.

The article considers the possibility of using the gas turbine SGT5-9000HL (Siemens) with the capacity of 593 MW and modernized steam turbine K-300-240-1 (LMZ), with steam generation in a three-circuit HRSG. The possibility of steam turbine operation at the expense of heat of GTU exhaust gases was substantiated.

 

62 Application of producer gas instead of natural gas: how it affects the main equipment of a CCGT

Coal is an underrated resource capable of supplying energy to the world and Russia for centuries. The development of energy generation technologies based on coal fuel is key to ensuring the country's energy security and a potential driver for the economic development of remote regions where gasification is technically and economically challenging. The aim of this study was to investigate the impact of using syngas derived from coal, based on Russian technology for coal gasification in a fixed bed with air blowing, on the performance indicators of the main equipment of a combined cycle gas turbine (CCGT) plant when burned in the combustion chamber (CC) of the gas turbine unit (GTU). The performance indicators of the main elements were calculated using material and heat balance equations, as well as known chemical reaction equations. The work compares the performance indicators of the CCGT equipment when operating on natural gas and syngas, taking into account the integration of gasification system components into the CCGT scheme. Based on the obtained data, it is shown that the primary factor affecting the plant's operation is the 6.8-fold increase in fuel consumption in the CC, which in turn leads to an increase in the plant's power output. Integrating a gas cooler (GC) into the CCGT scheme through connection with the heat recovery steam generator (HRSG) results in reduced heat utilization but also lowers the risk of erosion on the final heating surfaces. The additional heat from the GC introduced into the cycle increases the power output of the steam turbine by 11.3%.

 

70 Trends in the development of last-stage turbine blades for TPP and NPP taking into account patent analytics

In recent years, despite the fact that efforts have been made in many countries to accelerate the energy transition to green energy instead of traditional energy, these attempts have not been successful. Currently, it can already be said that an erroneous development strategy was chosen, which led to multiple energy crises, both in European countries and in the United States. Mainly due to these circumstances, there has been a significant revision of energy development plans and a return to the development of traditional energy sources. It became clear that fossil-fuel power plants are needed, as well as energy storage systems should be created to ensure reliable energy supply. It also includes the transfer of nuclear generation to the category of green energy and the resumption of plans for the construction of nuclear power plants (NPP). In some countries, ultra-supercritical (USC) units are under mass construction. In these circumstances, when a number of countries have never abandoned traditional energy and continued to develop both nuclear and thermal energy, patent analytics can help identify development trends in some areas and reveal possible technology leaders who will appear in the coming years.

 

76 Utilization of low-potential heat using heat pump systems to improve the energy efficiency of data centers

The paper considers the problem of utilization of low-potential heat generated during the operation of server equipment of data processing centers (DPC).

88 Analysis of the effect of nozzle unit design on the operation of a radial-centripetal turboexpander

Decentralized generation is a topical issue for the whole world, including our country. One of the examples of this type of power generation is the use of turbo detanders. The analysis of the reviewed literature has shown that at present low-power detanders are poorly developed despite the fact that for various objects of gas transportation and gas distribution networks there is a need for a generation source of less than 1 kW. One of the variants of such machines are radial centripetal low-flow turbo-detanders. To date, there is little experience in the development of these machines, which makes the development of key elements of the flow part of these machines, in particular, nozzle apparatuses, urgent. In this article the influence of nozzle shape on turboexpander performance is considered by means of numerical experiment.

The purpose of this paper was to obtain the best nozzle channel geometry to obtain close to nominal flow and power characteristics of turboexpander. The methodology includes consideration of different nozzle channel designs and evaluation of the influence of their geometric dimensions on the operation process.
