Статья посвящена вопросам численного моделирования рабочих процессов камер сгорания газотурбинных двигателей, работающих на альтернативном топливе. Исследованы вопросы возможности применения RQL-технологии сжигания синтетического топлива и необходимости введения конструктивных модификаций топливосжигающих устройств с целью улучшения экологических характеристик существующих камер сгорания. Концепция RQL камеры сгорания представлена в качестве стратегии по снижению выбросов оксидов азота (NOₓ) газотурбинных двигателей. Концепция отличается высокой стабильностью сгорания за счет богатой первичной зоны.
This scientific paper is devoted to the problems of numerical simulation of working processes in the combustion chambers of gas turbine engines that operate using an alternative fuel. The issues related to the possibility of the use of RQL technology for synthetic fuel combustion and the need for the introduction of structural modifications of fuel burning plants to improve ecological characteristics of available combustion chambers have been discussed. A conception of RQL combustion chamber is given as the strategy to reduce the emissions of nitrogen oxides (NOₓ) of gas turbine engines. This conception differs by high combustion stability due to the rich primary zone. In stationary conditions standard combustion technologies are considered to be the technologies with a high-speed preliminary mixing. Safety conditions are not very important, the work cycle is more restricted and the reduction of NOₓ emissions is more essential in contrast to RQL technology. Nevertheless, the RQL combustion technology is of great interest for the stationary application due to the possibility of more efficient processing of the fuel of a compound composition and also for the processing of fuels of a different component composition. An additional research is required to study the NOₓ formation in RQL configurations.
