Abstract
The characteristics of the combustion process of liquid (diesel) fuel in a high-speed jet of superheated water vapor in the combustion chamber of a hot water boiler are studied at a thermal power of the burner device approximately equal to 40 kW. It is shown that the burner device, created on the basis of the technology of fuel atomization with a steam jet, meets modern technical and environmental standards and has a number of advantages over analogues. It has been established that the addition of steam makes it possible to reduce the concentration of CO and NOx in combustion products several times. At the same time, the volume of emissions of carbon monoxide and nitrogen oxides when using the burner design under study is significantly (2.5 and 1.4 times, respectively) less than when using a serial analogue of the Weishaupt burner device. Recommendations for optimizing the operation of such devices are presented.
