Russian scientists reduced harmful aviation and energy emissions 18:04

Scientists of Perm National Research Polytechnic University (PNIPU) proposed a new way to heat the fuel gas, which reduces the emissions of harmful substances in gas turbine engines. This was reported to the “Gazeta.ru” in the press service of the scientific institution.

Gas turbines commonly used in energy and aviation release carbon dioxide and nitrogen oxides, harmful to health and environment. The problem is particularly acute, while useful fuel mixtures with more air than fuel are used. Such mixtures are not completely burned, reduces the efficiency of the engine and increases emissions.

Traditionally, the fuel mixture is heated in the combustion chamber, which leads to pressure loss and reduction in efficiency. PNIPU was offered to heat the fuel gas before supplying the combustion chamber. This improves mixing fuel with air and makes burning more stable.

Experiments were performed on a special stand where the characteristics of the applications were examined. Fuel and air were heated by a heater of up to 50 kW and the parameters were fixed by the sensors. The concentration of harmful substances was measured by a gas analysis.

“24% in front of the combustion chamber reduces carbon monoxide emissions and slightly increases nitrogen oxides (15%). However, the general toxic emission level remains significantly lower than the traditional high temperature burning, R cokest and cosmic technical and energy systems are senior teacher Alena Shilova.

Scientists also developed formulas that allow more accurately predicted carbon and nitrogen oxide emissions for low temperature burning. These calculations take into account the temperature of the fuel gas, the pressure in the combustion chamber, the volume of the room and the remaining of the mixture in the combustion area. This will help engineers optimize engines.
