Abstract
Calculation of the external heat exchange in the combustion furnaces is always complicated because of insufficient knowledge of the convective heat transfer characteristics. It is extremely important to know the above-mentioned characteristics as the modern hating furnaces are equipped with the high-speed burners providing for running of the gas-air mixture at a speed of 100 – 150 m/sec. The present article demonstrates a procedure and results of the investigation of the complicated external heat transfer in the operating industrial furnace equipped with high-speed recuperative burners and lined with ceramic-and-fibrous blocks. The article also includes the recommendations on application of the submitted procedure and results of the abovementioned investigations.
