Abstract

Abstract: Burner structures and combustion modes of W-type radiant tube system and dual P-type radiant tube system were analyzed, and the key performance indicators of the two kinds of radiant tube heating systems were tested and compared, including flue gas circulation rate, temperature deviation, fuel efficiency and NO_x. The results show that the dual P-type radiant tube combustion system has greater value of popularization and application, because it has better uniformity of tube wall temperature, remarkable energy saving effect, and the ability to use higher power burner to reduce the number of heating system and control module and to reduce the investment cost.

Key words: radiant tube, power, temperature distribution, fuel efficiency, NO_x discharge
