| Title of the article | Improving the method for determining the composition of solid waste combustion products |
| Abstract. | Problem statement. The main parameter that allows to take into account the influence of the content of municipal solid waste components on the yield of combustion products of a heterogeneous mixture during thermal utilization is its calorific value. There are methods for setting the calorific value, but they are tied to assumptions that allow only a rough estimate of this parameter. The dependence of the influence of the calorific value on the operating characteristics of municipal solid waste has not been sufficiently studied. The purpose of the work is to numerically study the operating characteristics of fuel, predict the composition of a multicomponent gas mixture during municipal solid waste combustion. The objectives of the study are: to determine the dependencies and design parameters of thermal utilization of municipal solid waste, which improve the characteristics of the combustion products of the gas mixture. Results. The paper presents the results of numerical studies of the composition and operating characteristics of fuel during thermal utilization of municipal solid waste. A formula is derived for the dependence of the calorific value on the operating characteristics of municipal solid waste for the temperature range (1000 ... 2200 K). The influence of the calorific value of municipal solid waste on the prediction of the composition parameters is shown. The dependence has been formed to determine the lower calorific value at a variable temperature. In the studied temperature range, no condensate is formed during the combustion of solid waste. The main components of the combustion products are: nitrogen dioxide (~12%), water (~18%) and molecular nitrogen (~66%). Toxic components account for no more than 4%. The remaining substances are neutral in terms of toxicity. Conclusions. The significance of the obtained results lies in the possibility of adjusting the methods for calculating the composition of combustion products, due to the use of the derived improved formula for determining the calorific value of solid waste, in order to clarify the methods of air protection. The calculation results in this approximation are a kind of criterion for assessing the energy and environmental efficiency of real waste incineration plants. |
