Online blockage removing device for combustor

Abstract

The invention provides an online blockage removing device for a combustor, and the online blockage removing device is applied to the technical field of combustor auxiliary parts. A center cylinder (2) of the combustor is provided with a plurality of spinning disks (3) along the surface of the center cylinder (2) by one circumference. Nozzles (6) are arranged at one ends of spraying pipes (5) of a blockage removing part (4) of the online blockage removing device for the combustor and are arranged to be of structures capable of being aligned with the positions of combined root parts (7) of the spinning disks (3) and the center cylinder (2), and the other ends of the spraying pipes (5) are connected with a nitrogen gas source (8) and are connected with a water source (9) at the same time. The online blockage removing device for the combustor is simple in structure, comburent dirt accumulated at the combined root parts of the center cylinder and the spinning disks in the combustor can be online swept in the continuous combustor working state, and blockage of the spinning disks of the combustor is effectively removed through sweeping; and meanwhile, the work efficiency of the combustor is improved, and combustion stability is kept.

Description

technical field [0001] The invention belongs to the technical field of burner auxiliary components, and more specifically relates to an online blockage removal device for a burner. Background technique [0002] At present, the double-swirl gas burner is widely used in full-fired gas boilers and mixed-fired gas boilers due to its relatively simple structure, high degree of mixing of combustible gas and air, stable ignition, high power, and high combustion efficiency. Mainly include: blast furnace gas, coke oven gas and converter gas. Since this type of burner uses double swirl flow, the design resistance is larger than that of the DC burner. The angle of the swirl sheet and the installation position of the swirl sheet are relatively fixed, and the user can no longer adjust it. Therefore, this type of combustion The device is adapted to burn relatively clean gaseous fuels. Because of this, the burners in the prior art have the following problems when burning unclean fuels, m...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: to provide a simple structure, which can carry out on-line purging of the combustible ash accumulated at the joint root of the central cylinder body and the swirl plate in the burner when the burner continues to work, Clean the blockage of the swirl plate of the burner, solve the problem that the burner needs to be shut down for cleaning, improve the working efficiency of the burner, and maintain the combustion stability of the burner.
