INVESTIGATION OF THE THERMAL POTENTIAL OF THE AIR IN THE OVERHEAD SPACE OF A GLASS FURNACE

The purpose of the work is to determine the thermal potential of the air of the overhead space of the glass furnace, heated at the expense of heat losses through the refractory masonry of the furnace and the open part of the gas duct of the recuperator, diverting combustion products from the flame space of the furnace and the search for directions of possible use of thermal energy. It was determined that the losses with the air leaving the building are 1.057 MW, or 10 % of the fuel consumption in the unit, the average air temperature is 63°C. As proposals the possibility of heat recovery of low-potential RER is presented, which can be effectively used for drying of raw materials at the site of preparation of raw components to the process of charge making. Calculation of heat content of air flow shows that drying of material can be provided at air flow rate of 3-5 m3/s.
