Abstract
Spent petroleum products can be efficiently used as an energy source in industrial thermal power engineering. Matters concerned with the energy efficiency and environmental safety of using this type of fuel and development of burners for spent petroleum products are extremely relevant. To analyze the energy efficiency of industrial plants that use spent petroleum products as fuel, the heating value of these products has to be known. The data on the lower heating value and viscosity of various petroleum fuels published in the literature are systematized. The results obtained make it possible to estimate the heating value of spent petroleum products by using their viscosity as a parameter. A set of works aimed at developing an evaporative burner for high-quality combustion of various spent petroleum products has been accomplished. Based on experimental studies of the combustion of various spent petroleum products in the evaporative burner, relationships between the viscosity, lower heating value, and flame length and temperature are revealed. By using the obtained relationships between the thermal parameters characterizing the combustion of spent petroleum products, it becomes possible to assess the possibility of effectively neutralizing such pollutants as halogens and polychlorinated biphenyls. The boundary of the domain in which spent petroleum products can be combusted in an environmentally efficient manner with neutralizing such pollutants as halogens and polychlorinated biphenyls has been determined and described analytically. Dependences of the maximum allowable concentrations of pollutants in spent petroleum products on their viscosity, lower heating value, and flame temperature are presented. The obtained results can be used to develop domestic regulatory documents on energy efficient and environmentally friendly combustion of spent petroleum products in thermal engineering plants.
