Analysis of a Regenerative Gas Turbine Cycle for Performance Evaluation | Semantic Scholar
The effect of a regenerative heat exchanger in a gas turbine is analyzed using a regenerative Brayton cycle model, where all fluid friction losses in the compressor is quantified by an isentropic efficiency term and all global irreversibilities in the heat exchanger are taken into account by means of an effective efficiency. This analysis, which generalizes that reported by Gordon and Huleihil for a simple, non-regenerative Brayton cycle, provides a theoretical tool for the selection of optimal operating conditions in a regenerative gas turbine for optimum value of compressor efficiency. Regenerative gas turbine engine cycle is presented that yields higher cycle efficiencies than simple cycle operating under the same conditions. The power output, efficiency and specific fuel consumption are simulated with respect to operating conditions. The analytical formulae about the relation to determine the thermal efficiency are derived taking into account the effected operating conditions (ambient temperature, compression ratio, regenerator effectiveness, compressor efficiency and turbine inlet temperature). Model calculations for a wide range of parameters are presented, as are comparisons with simple gas turbine cycle. The power output and thermal efficiency are found to be increasing with the regenerative effectiveness, and the compressor efficiency. The efficiency increased with increase the compression ratio to 15, then efficiency decreased with increased compression ratio, but in simple cycle the thermal efficiency always increases with increased in compression ratio. The increased in ambient temperature caused decreased thermal efficiency, but the increased in turbine inlet temperature increase thermal efficiency.

Energies | Free Full-Text | Gas Turbine Cycle with External Combustion Chamber for Prosumer and Distributed Energy Systems
The use of various biofuels, usually of relatively small Lower Heating Value (LHV), affects the gas turbine efficiency. The present paper shows that applying the proposed air by-pass system of the combustor at the turbine exit causes tan increase of efficiency of the turbine cycle increased by a few points. This solution appears very promising also in combined gas/steam turbine power plants. The comparison of a turbine set operating according to an open cycle with partial bypassing of external combustion chamber at the turbine exit (a new solution) and, for comparison, a turbine set operating according to an open cycle with a regenerator. The calculations were carried out for different fuels: gas from biomass gasification (LHV = 4.4 MJ/kg), biogas (LHV = 17.5 MJ/kg) and methane (LHV = 50 MJ/kg). It is demonstrated that analyzed solution enables construction of several kW power microturbines that might be used on a local scale. Such turbines, operated by prosumer’s type of organizations may change the efficiency of electricity generation on a country-wide scale evidently contributing to the sustainability of power generation, as well as the economy as a whole.

Currently, it is possible to obtain a stable flame during the combustion of low calorific fuels in a wide range of operating parameters, such as the molar composition of the fuel and the excess air coefficient. However, the biogas must be properly cleaned and dried so that it does not damage the turbine. Depending on the origin, the biogas composition is variable. The calorific value depends primarily on the methane content. Currently, biogas, that is combusted in gas turbines, has the methane content from 35% to 100%. As a result of continuous combustion with excess air and low pressures in the combustion chamber, turbines as well as microturbines have a significantly lower value of exhaust emissions as compared to the reciprocating engines. The combustion of low calorific gases has a significant impact on the natural environment by reducing the emission of nitrogen oxides [
]. During managing of the production process, the amount of energy consumed and the production of post-production waste emitted to the atmosphere are analyzed at each stage of the production process. The analysis of energy expenditure is carried out in a comprehensive manner, concerning the whole life cycle of the product. In this context, even electromobility requires a huge amount of energy used to extract and process lithium, cobalt, and manganese; the key raw materials needed to produce batteries for electric cars. Thermodynamic cycles and the use of modern calculation tools are also important in this process [
Cogeneration Power-Desalting Plants Using Gas Turbine Combined Cycle | IntechOpen
The gas-steam turbine combined cycle (GTCC) is the preferred power plant type because of its high efficiency and its use of cheap and clean natural gas as fuel. It is also the preferred type in the Arab Gulf countries where it is used as cogeneration power-desalting plant (CPDP). In this chapter, descriptions and analysis of the GTCC components are presented, namely, the gas turbine cycle (compressor, combustor, gas turbine), heat recovery steam generator, and steam turbine. Combinations of the GTCC with thermally driven desalination units to present CPDP are presented. A parametric study to show the effect of using GTCC on several operating parameters on the CPDP is also presented, as well as cost allocation methods of fuel between the two product utilities (electric power and desalted seawater are also presented).

Energies | Free Full-Text | Thermodynamic Performance Analysis of a Biogas-Fuelled Micro-Gas Turbine with a Bottoming Organic Rankine Cycle for Sewage Sludge and Food Waste Treatment Plants
In the Republic of Korea, efficient biogas-fuelled power systems are needed to use the excess biogas that is currently burned due to a lack of suitable power technology. We examined the performance of a biogas-fuelled micro-gas turbine (MGT) system and a bottoming organic Rankine cycle (ORC). The MGT provides robust operation with low-grade biogas, and the exhaust can be used for heating the biodigester. Similarly, the bottoming ORC generates additional power output with the exhaust gas. We selected a 1000-kW MGT for four co-digestion plants with 28,000-m3 capacity. A 150-kW ORC system was selected for the MGT exhaust gas. We analysed the effects of the system size, methane concentration, and ORC operating conditions. Based on the system performance, we analysed the annual performance of the MGT with a combined heat and power (CHP) system, bottoming ORC, or both a bottoming ORC and CHP system. The annual net power outputs for each system were 7.4, 8.5, and 9.0 MWh per year, respectively.

The ORC system is composed of a pump, evaporator, turbine, condenser, and cooling water pump. After the working fluid leaves the pump, it enters the evaporator and absorbs heat from the heat source. The source fluid enters the evaporator and leaves after heating the working fluid. The high-pressure working fluid vapor drives the turbine to generate the expansion work while relieving the pressure with declining temperature. Low-pressure vapor is extracted from the turbine and flows to the condenser, which reduces its temperature using cooling water and produces heating water for the anaerobic digesters. The anaerobic digester temperature must be kept within a proper range to produce biogas. The working fluid is R245fa.
shows a schematic of the system. The Brayton cycle is the topping cycle, and the Rankine cycle is the bottoming cycle. In the case of the Brayton cycle, ambient air enters the air compressor, which raises the pressure and temperature. The air is heated up in the recuperator using exhaust gases from the gas turbine and mixed with compressed fuel in the combustor. The combustor limits the maximum temperature of the product gases, which occurs at the turbine inlet temperature. Next, the hot gases expand in the gas turbine, which is coupled to a generator, and then they enter the low-temperature heat recovery system. A single shaft mechanically connects the compressor and the turbine to the electric generator.
This study analyses the performance of an MGT/ORC system for utilizing biogas from sewage sludge and food waste. The objective of this study is to clarify the relationship between the scale of a plant and the optimal size of the MGT and ORC. The performance of the MGT is determined based on a commercial Capstone C1000 unit, and a recuperator is considered to improve the system performance. An ORC system with a turbine is used for efficient recovery of the waste heat produced by the exhaust gas of the MGT. Cooling water from the condenser outlet is considered as a heat source for the digesters. The proposed systems are modeled based on the mass and energy balances.

I am not in the thermal power industry, but I guess I have always felt that the industry should use HHV efficiency, especially now as greenhouse gases threaten the environment with drought, floods, famine, refugees. And those Carbon emissions and pollution are, to my limited knowledge, at least to first order probably second, correlated with HHV, not LHV, i.e., to the the the amount of carbon in the fuel. I may be making a mistake right here, given the complicated chemistry of hydrocarbon combustion, so my apologies if so.
Calculating or predicting the overall performance of a combined cycle power plant, specifically a combined cycle gas turbine (CCGT) power plant is sometimes difficult for most design engineers. Your favorite energy technology expert has derived the following equation to guide the design engineer and project finance modeler or business development engineer in predicting the overall thermal efficiency of the combined cycle.
The only way to go higher than this is to improve further the gas turbine efficiency beyond 98%, boiler efficiency beyond 90%, raising the steam turbine efficiency beyond 40% and optimizing the proportion of energy output thru the gas turbine (currently 1/3) and the steam generator (balance of 2/3).
