Abstract

The basic principle and technical features of regenerative combustion technology is induced. Considering the problems faced in the development of current tubular furnace, the application feasibility of high temperature air combustion technology in tubular furnace is analyzed. A set of experimental installation of regenerative combustion tubular furnace is established in this paper. The experiment result shows that the regenerative heat exchanger is capable of decreasing the flue gas temperature in the tubular furnace under the dew-point temperature, the latent heat of condensate vapor is recovered, and the thermal efficiency is over 100% calculated by low calorific value. The impact of the switching time on the thermal efficiency is analyzed. Considering the thermal efficiency and equipment reliability, it is believed that the switching time between 40~60s is reasonable.
