The Experimental Investigation on the Internal Temperature Field of Regenerative Burners

The application of regenerative combustion technology to industry burners has been a huge success. This paper presents an experimental study on the change of the temperature field and the concentration of NO in the flue gas in an industrial furnace. The result showed that the concentration of NO increased with the rise of temperature. For the reversing time of 20s, 40s, 60s, and 80s, the temperature of each point changed in accordance with similar rules, but the temperature of the former three measuring points did not obviously change. The heat transfer occured mainly in the last two layers of the regenerative cells, and the utilization of all the regenerators was only 40 percent. The heating curve of the sixth measuring points was significantly different from the cooling one. With the increase of the reversing time, the flue gas and the air temperature variation also increased.
