Abstract

The paper experimentally investigates the method of steam jet combustion for low emission of CO and NOx during the liquid hydrocarbon fuel burning as applied to high-pressure combustion chambers. The purpose of the work is to adjust a promising combustion method to the tasks of energy technologies and creation of the working body of power plants. The novelty of the method is the non-contact atomization of fuel by steam jet and realization of the analog of staged combustion due to the presence of gas generation chamber, which allow one to obtain ultra-low NOx and CO emissions (less than 10 ppm) at high completeness of fuel combustion. In this study, the effective steam/fuel/primary air/secondary air ratios are determined by experimental methods to achieve the best performance of the device: 0.75/1/5/15.1. The combustion products are a vapor-gas mixture with the promise of use as a working body for power plants. Energy consumption for steam generation does not exceed 8 %.
