- to determine technical and economic performance of boiler units M 100 using fuel oil and hydro stabilized fuel;
- to determine the quantity of hydrocarbons, sulfur and nitrogen oxides emissions for each tested fuel type during operation at different loads.
Fig. 1 shows a diagram of measurement points for DE 16-14 GM boiler when using fuel oil.Fig. 1. DE 16-14 GM boiler measurement points diagram: 1 – fuel pressure in the pipeline, 2 – fuel pressure on the burner, 3 – fuel temperature, 4 – air pressure on the burner 5 – cold air temperature, 6 – air pressure downstream of the fan 7 – combustion chamber rarefaction, 8 – rarefaction downstream of the boiler 9 – flue-gas temperature downstream of the boiler, 10 – flue-gas analysis downstream of the boiler, 11 – rarefaction downstream of the economizer, 14 – outgoing gas temperature, 15 – outgoing gas analysis, 16 – water temperature upstream of the economizer, 17 – water temperature downstream of the economizer, 18 – boiler outlet steam pressure 19 – boiler outlet steam flow The characteristics obtained as a result of the experiments are presented in the figures below.

|Fuel oil M-100||9.59||12.18||13.11||13.38|
- nitrogen dioxide, by 23%;
- sulfur dioxide, by 26%;
- carbon monoxide, by 84%;
- suspended solids, by 87%.
- increase the service life of boiler equipment;
- ensure reliable operation of a boiler when original fuel oil is watered;
- exclude settling and draining operations from your fuel preparation technology;
- reduce the intensity of low-temperature sulfuric acid corrosion of your equipment;
- use fuel oil of lower quality in order to generate heat.
