Investigations of a Gas Turbine Low-Emission Combustor Operating on the Synthesis Gas

Abstract

Investigations of the working processes in a gas turbine low-emission combustor operating on the synthesis gas, in which the principle of RQL (Rich-Burn, Quick-Mix, and Lean-Burn) combustion technology is realized, have been performed. Selected concept of a gas turbine combustor can provide higher performance and lower emission of nitrogen oxides and demonstrates satisfactory major key parameters. Obtained results and recommendations can be used for the gas turbine combustor operation modes modeling, geometry optimization, and prospective power generation units design and engineering.

Application analysis of a hybrid solid oxide fuel cell-gas turbine system for marine power plants

“…The developed model of chemically reacting flows is based on solving an equation system which describes the convection and diffusion transfer of concentrations for each of the reacting mixture components. A detailed description of the model can be found in (Serbin 1998;Matveev and Serbin 2006;Serbin 2006;Matveev et al 2007b;Serbin et al 2011Serbin et al , 2014.…”

“…As the represented kinetic mechanism of off-gas oxidation contains a lot of reactions, they require the use of a combustion model capable of predicting the special features of chemical species. The Eddy-Dissipation-Concept (EDC) is such a model which considers the interaction of chemical kinetics and turbulence of the flows (Serbin et al 2011;Cherednichenko et al 2019). The model assumes that the reactions occur in small turbulent structures called small-scale reactors.…”

“…A mathematical model of nitrogen oxides emission is a system of mass transfer equations that include convection, diffusion, formation, and decomposition of NO and related compounds. The influence of the reagent's residence time in the reaction volume on the mechanism of NO formation is considered in the convection terms of the defining equation (Serbin et al 2011):…”

“…The received data were verified by comparison of the main afterburner parameters (consumption of the ejected air and the amount of toxic components on the exhaust) obtained by computational and experimental methods. The comparison of the calculated and experimental values of the afterburner parameters (Serbin and Goncharova 2017) are shown in Figure 6.…”

Investigation of the Combustion Processes in the Gas Turbine Module of an FPSO Operating on Associated Gas Conversion Products

“…In the present work, we use an approved early [36,37] simplified 35-reaction reducing mechanism (Table 1) to carry out a detailed analysis of the combustion operating processes. The validity of using this simplified mechanism in threedimensional investigations of synthesis gas combustion was demonstrated in [38].…”
