“…В этом случае необходимы модели, учитывающие кинетику физико-химических превращений топливной частицы в несущем потоке газа. 2D-и 3D-моделирование газогенераторов позволяет решить ряд конструкционных или режимных вопросов, на-пример, связанных с выбором расположения питателей [21,22]. Однако для анализа большого количества вариантов эти модели оказываются слишком ресурсоемкими, поэтому на первом этапе анализа обычно достаточно более упрощенного рассмотрения.…”

“…This water, if condensed, dissolves oxygen and acid gases resulting from the burning of the foul compounds (present in the fuel), causing corrosion of the waste heat boiler cold spots [57]. Furthermore, an extensively foul fuel requires a scrubber to meet stringent environment limits [58]. The two cycles, the Brayton cycle and the Rankine cycle, are commercially termed as CCGT.…”

In combined cycle gas turbines, most of the energy loss is usually due to the high temperature of the exhaust gases. Different heat recuperation methods are used. In this study, a novel direct method for heat recovery is investigated. Confidence in the results is established by accounting for all the losses and simulation errors while comparing with the conventional cycle. Aspen HYSYS and MATLAB are the simulation tools used. The General Electric (GE) 9HA.02 combined cycle is taken as a base case. Five gases, air, argon, hydrogen, nitrogen, and carbon dioxide, are studied with the proposed modification. The efficiency maximization function is updated and the pressure and temperature ratios of individual Brayton and Rankine cycles are discussed. The combustor/heat exchanger is modified and simulated according to the known principles of heat and momentum transfer. The whole simulation algorithm is provided. Equation of state (EOS-PR) is used to calculate the properties at every discretized step (for H2, critical properties are modified/HYSYS inbuilt feature). Different gases are analyzed according to their property profiles over the whole cycle. The effect of fluid properties on efficiency is discussed as a guideline for any tailored fluid.

“…The syngas which is produced after the gasification of coal is sent to the combined power systems that are called gas turbine and steam turbine systems. As a result, the electricity is produced [40][41][42][43]. Hydrogen can also be produced with integrated systems that are applied to coal gasification systems [44][45][46][47][48][49][50].…”

Undoubtedly, energy plays a vital role in every sphere of life. Fossil energy sources such as coal and natural gas are generally used for energy production. People are looking for more efficient use of the source in recent years due to the rapid depletion in the fossil fuel resources. Gasification of coal is a useful method for produce clean and efficient energy. This study was carried out to find out the various trends in scientific studies that provide literature for the field of coal gasification on world. All data used in this study have been reached from Web of Science database. In this study, the coal gasification related to both bibliometric and historical analyses were investigated. The Web of Science database was scanned for the articles about coal gasification between the years of 1989 and 2020. The considered parameters in the bibliometric analysis are the number of citations and documents, authorships and ownerships, patterns of international collaborations and addresses.
