PROBLEMS OF BURNING FUEL MIXTURES OF VARIABLE COMPOSITION
The problems of the use of waste gases of petrochemical complex in the composition of fuel mixtures are considered. The main technological processes of oil refining from the point of waste disposal are analyzed. A numerical study of the characteristics of the mixture of traditional fuel with waste gases in different ratios. It is shown that when calculating the thermal characteristics of the studied mixtures by the normative method, there are significant differences in the indicators depending on the content of the added waste. On the other hand, the generalized characteristics of the fuel mixtures obtained with the use of the method of M.B. Ravych practically do not change. The operational characteristics of the main fuel and top-shower mixtures are compared. It is noted that the high hydrogen content in the mixture of fuel and blow-off gases causes a significant expansion of the ignition limits and leads to an increase in the rate of flame propagation during combustion compared to the traditional fuel type – natural gas. The results of mathematical modeling of the size and shape of the torch are presented. Identified the possible reasons of violations fuel process using mixtures of primary fuel and discharge accumulated gases. The necessity of correction of the method of Ravych and considered additions to the new calculation tables for the processing of the results of thermal tests in the combustion of fuel mixtures. The problems of combustion of mixtures of the main fuel and waste gases of the petrochemical complex are analyzed and recommendations for sustainable combustion of fuel mixtures of variable composition are developed. Economic and ecological efficiency of use of combustible wastes for the purpose of substitution of the main organic fuel is shown.
