Abstract The paper presents a comparative analysis of experimental data on combustion of liquid hydrocarbon fuels in the presence of superheated steam in two designs of the developed burners. By the example of diesel fuel burnt in a spray burner it is shown that lower values of nitrogen oxide contents in the exhaust gases are achieved in comparison with an evaporative burner. At that, the content of carbon monoxide in some regimes is lower for the evaporative burner. The regimes with the minimum content of toxic combustion products are found for both designs of the burners.

The article underlines the interest to using gas fuel in diesel engines of the coastal fishing vessels. If the change to liquefied natural gas is limited by the lack of bunkering capabilities in the Russian ports, using compressed gas has become widespread in transport and in the household. A number of gas fueling stations are already available for this purpose. It seems reasonable to start the conversion of the port fleet to compressed gas from using the motor gas bottling equipment for that purpose. It is important to evaluate the change in engine performance parameters when converting to compressed gas. Compressed gas is a mixture of gases such as propane, ethane, butane, methane, etc. There is given the percentage of each gas content, according to GOST. The quantitative composition of the pure compressed gas combustion outcomes, as well as the gas ignited by the ignition diesel fuel was determined by the oxidation reactions of the chemical elements of which they consist, as well as by oxygen from air. As a result of regression analysis applied to define the properties of water vapor and gases, there have been derived linear and quadratic approximating dependences of the heat capacities of gases (CO2, N2) and water vapor (H2O) on temperature. There have been obtained the equations for determining the heat capacity of the combustion products of compressed gas for fuel grade A and B. There have been produced the formulas for determining heat capacity of pure combustion products of compressed gas ignited by the ignition diesel fuel. The obtained expressions are recommended to be used for analysis of the working cycle of a diesel engine running on the compressed gas.

Oxidation of diesel fuel was studied using vibro-liquefied and fluidized beds of disperse bank sand in the presence of iron-containing microspheres isolated from flue ash of coal-fired boilers: ferrospheres and cenospheres activated with iron oxide. The obtained results are compared to the available data on oxidation of diesel fuel using microspheres of commercial catalysts for complete oxidation of organic compounds. Deeper oxidation of diesel fuel was observed at 500–600 °C in the presence of ferrospheres and cenospheres bearing iron oxide than in the vibro-liquefied bed of the inert material (bank sand). The most complete oxidation (84.3 %) was observed with ferrospheres at 700 °C. The ferrospheres were used for oxidation of diesel fuel in the fluidized bed of the inert material and they seemed less active under these conditions than the commercial catalysts based on СuСr2О4/Аl2О3and disperse Fe2O3. Nevertheless, the oxidation rate as high as 97.8 % can be achieved in the presence of ferrospheres by arranging jet fire above the bed. If so, the flame length decreases by half in comparison to the flame above the bed of the inert material. These observations, as well as a decrease in the proportion of CO and unburned carbon in combustion products indicate the catalytic activity of ferrospheres fed to the flame.
