Original abstract
Combustion of waste fuels becomes more and more commonplace. The waste liquids often have low heating value, variable physical properties and may contain solid particles. It is necessary to account for these features when selecting an appropriate atomizer. Our task was to design an atomizer for simultaneous atomization of polymer solution and cracked oil. The polymer solution has high viscosity, low heating value and contains particles up to 2mm in diameter. The oil has a higher heating value and is used to assure an effective combustion. It is important to enable independent control of both liquid flow-rates. The atomizer should be operated under low fluid pressure about 0.2-0.3 MPa and should provide a stable spray of good quality to improve combustion efficiency and decrease exhaust gas emissions compared to the current design.
