Abstract

Abstract The study is devoted to the possibility of increasing the efficiency of the working process in dual-fuel combustion chambers of gas turbine engines for FPSO vessels. For the first time, it is proposed to use the advantages of plasma‒chemical intensification of the combustion of hydrocarbon fuels in the dual-fuel combustion chambers, which can simultaneously operate on gaseous and liquid fuels. A design scheme of a combustion chamber with a plasma‒chemical element is proposed. A continuous type mathematical model of a combustion chamber with a plasma‒chemical element has been developed, which is based on the solution of a system of differential equations describing the processes of chemical reactions in a turbulent system, taking into consideration the initiating effect of the products of plasma‒chemical reactions on the processes of flame propagation. A modified six-stage kinetic scheme of hydrocarbon oxidation was used to simultaneously predict the combustion characteristics of the gaseous and liquid fuels, taking into account the decrease in the activation energy of carbon monoxide oxidation reactions when the products of the plasma‒chemical element are added. The results reveal that the addition of plasma‒chemical products significantly reduces CO emissions in the outlet section of the flame tube (from 25‒28 ppm to 3.9‒4.6 ppm), while the emission of nitrogen oxides remains practically unchanged for the studied combustion chamber. Further research directions are proposed to enhance the working process efficiency of a dual-fuel combustion chamber for gas turbine engines as part of the power plant of FSPO vessels.
等离子体化学元件双燃料燃气轮机燃烧室效率的研究
摘要本研究致力于提高浮式生产储油船燃气轮机发动机双燃料燃烧室工作过程效率的可能性。首次提出利用等离子体化学强化碳氢化合物燃料在双燃料燃烧室中燃烧的优势,该燃烧室可以同时使用气体和液体燃料。提出了一种等离子体化学元件燃烧室的设计方案。基于描述湍流系统中化学反应过程的微分方程组的解,考虑到等离子体化学反应产物对火焰传播过程的引发作用,建立了带有等离子体化学元件的燃烧室的连续型数学模型。考虑到添加等离子体化学元素产物时一氧化碳氧化反应活化能的降低,使用改进的碳氢化合物氧化六阶段动力学方案同时预测气体和液体燃料的燃烧特性。结果表明,等离子体化学产品的添加显著降低了火焰管出口部分的CO排放量(从25-28ppm降至3.9-4.6ppm),而所研究燃烧室的氮氧化物排放量几乎保持不变。提出了进一步的研究方向,以提高燃气轮机发动机双燃料燃烧室的工作过程效率,作为FSPO船舶发电厂的一部分。
