DEVELOPMENT OF THE DESIGN OF A PYROLYSIS INSTALLATION FOR WASTE DISPOSAL WITH DIRECTED DISTRIBUTION OF HEAT FLOWS

Abstract

Waste recycling is now gaining in importance around the world. The range of drugs used, the volume and degree of danger of waste generated by the activities of industrial institutions is increasing. As a result, the risk of epidemics increases. Therefore, the creation of an effective design of the furnace as the main unit of the pyrolysis unit is an urgent task. The purpose of the furnace environment is to create in the working chamber the necessary and optimal physical and chemical conditions for the implementation of thermotechnological, thermotechnical and mechanical processes and protection of raw materials and obtained target products from unwanted chemical processes. The following substances are used as heat extraction reagent: air, inert and recirculating gases, water, steam, etc. If necessary, a slow decrease in temperature, cooling of materials and products is carried out together with the oven. Heat transfer processes in the waste disposal plant take place in difficult conditions and are characterized by a number of specific features. One of the main features is the high intensity of heat transfer. Another feature of thermal processes is the non-stationary temperature field in the working chamber of the furnace. Heat exchange in the working chamber of the furnace is carried out in three types - thermal conductivity, convection and thermal radiation, any combination of them or all types simultaneously, but one type of heat transfer always prevails over others in full or in a certain area of the furnace.
