МЕТОДИ УТИЛІЗАЦІЇ ТЕПЛОТИ І ОЧИСТКИ ВІДХІДНИХ ГАЗІВ ВАГРАНКОВИХ ПЕЧЕЙ У ПРОЦЕСІ ВИГОТОВЛЕННЯ МІНЕРАЛЬНОЇ ВАТИ

Abstract

The work is devoted to the problems of energy saving and ecological safety of industrial enterprises, which use in their technological process cupola furnaces with coke combustion for melting basalt and dolomite charge in order to obtain mineral wool. As a result of the operation of cupola furnaces, a large number of harmful substances are formed that need to be neutralized, and secondary heat is usually not used rationally. The aim of the work is to increase the efficiency of cleaning and heat utilization of process gases of cupola furnaces. The paper analyzes the methods of heat utilization and purification of waste gases of cupola furnaces in order to improve the technological process of mineral wool production, reduce operating costs and increase the efficiency of technological gas purification. Analytical and numerical research methods were used to
achieve the set tasks. Combined schemes of heat utilization and gas purification are offered, variants of application
of heat of exhaust gases for production of steam, hot water and the electric power are resulted. Methods of CO neutralization and reduction of SO2 concentration in exhaust gases are given. Possibilities of modernization of existing and construction of new gas removal systems, heat utilization and gas purification are considered. Practical recommendations for the implementation of energy saving measures during the production of mineral wool in coke cupola furnaces are given. The result of the implementation of the proposed technologies should be a deep utilization of the heat of the exhaust gases in order to its useful use and reduce emissions of harmful substances into the atmosphere.
