The results of experimental studies of heat losses via the enclosing structures of an operating brick-firing kiln using a thermal imager are described. Fuel consumption in firing comprises 80 - 85 percent of total fuel consumed in brick production. Therefore, it is essential to lower energy consumption in order to reduce production cost. Energy-saving measures at brick-firing kilns are oriented in three directions: upgrade of kilns and implementing scientifically substantiated firing conditions by automating the firing process and using state-of-the art gas burners with automatic control of gas : air ratio. rational utilization of waste heat, i.e., recovering the heat of flue gases and hot air from the cooling zone of the kiln improving the thermal insulation of kilns and kiln car lining.
