Abstract

The invention discloses a high-power pulse combustion steam boiler with multi-combustor parallel heating, belonging to the technical field of advanced energy sources. In the invention, the heat is supplied for the steam boiler by adopting a linkage mode of a plurality of groups of pulse combustors, that is to say, the plurality of pulse combustors are soaked in a boiler shell in parallel; safety ignition and control of the parallel pulse combustors are set by an electric control system program, therefore, independent ignition-flameout protection-restarting of each pulse combustor in the plurality of parallel pulse combustors can be realized, and the safe and automatic control function can be achieved; and a pipe network is added as a waste heat recovery device in a decoupling chamber so as to fully utilize the heat and improve the heat efficiency of the steam boiler. The high-power pulse combustion steam boiler realizes the high-power steam boiler design on the premise of ensuring the stable operation of the pulse combustors; the automatic control program of safety ignition-flameout protection-starting of the combustor groups ensures the ignition safety and reliability of the pulse combustors; and the waste heat recovery device ensures that the flue gas temperature is reduced to 180 DEG C and the heat loss is reduced.

Description

technical field [0001] The invention belongs to the field of advanced energy technology, in particular to a multi-burner parallel heating high-power pulsating combustion steam boiler, in particular to the parallel structure and parallel control of pulsating burner groups. Background technique [0002] Pulsating combustion is a special periodic pulsating combustion process that is different from the conventional steady-state combustion process. Compared with conventional combustion technology, pulse combustion technology has high combustion intensity, large heat transfer coefficient, CO, NO X It has the advantages of small discharge, self-priming and supercharging, and compact structure. In the 1960s, people began to apply pulse combustion technology to heating, heating and other aspects. In the 1980s, Europe, the United States, and Japan successively developed commercial and household pulse combustion steam boilers, heaters, and food ovens. [0003] Although pulsating com...
