Firing heavy liquid hydrocarbons in the heat generator with the wick burner in the vortex recirculation flow

Создан теплогенератор для сжигания тяжелых углеводородов в вихревом рециркулирующем потоке. Выполнены экспериментальные исследования по сжиганию отработанного машинного масла показавшие, что процесс его сжигания можно проводить без нарушений норм на вредные выбросы (NOx, CO). Выполненные расчеты показали удовлетворительное совпадение с экспериментальными значениями температуры на выходе из камеры сгорания, приемлемую погрешность (24 %) при прогнозировании выбросов и позволили оптимизировать конструктивные параметры камеры сгорания.For the qualitative fuel firing it is necessary to expose the combustible mixture for a sufficiently long period of time to high temperatures with simultaneous qualitative mixing of the fuel and the oxidizer. This scientific paper describes the experimental investigation whose results showed that the wick burner with the vortex recirculation motion of the air and the adjusted height of the primary chamber in the developed heat generator can provide a sufficiently complete firing of the mixture of heavy liquid hydrocarbons. The exposure time of the air-and-fuel mixture in the combustion chamber was regulated by the orificing of the outlet port. The temperature required for the minimization of carbon monoxide concentration was provided by the value of the regulated volume of the primary combustion chamber. A turbulence level in the vortex chamber above the wick depended on the availability of the countercurrent flow in the output section of the chamber. The data of experimental investigations of the firing of waste machine oil showed that this process can be carried out without the breach of harmful emission (NOx, CO) standards. The computations done using the licensed package PHOENICS showed a good coincidence with experimental temperature values in the combustion chamber, and the acceptable error (24 %) for the prediction of CO emissions and the divergence with the experimental data on the determination of the concentration of nitrogen oxides
