Description

Technical Field

[0001] The utility model belongs to the technical field of furnace sootblowing, and in particular relates to a furnace sootblower. Background Art

[0002] When the boiler is in operation for a long time, ash and coke will accumulate on the heating surface, which will deteriorate the heat transfer. For the tail flue, due to the long-term accumulation of combustibles, re-combustion deterioration accidents will also occur. Therefore, after the boiler has been in operation for a period of time, it is necessary to blow off the heating surface to clean it.

[0003] Sootblower is used for furnace sootblowing. Sootblower in the prior art is fixedly installed on the boiler. Since the boiler generates a large amount of heat when working, although the boiler will take certain insulation measures, it is impossible to completely prevent the heat dissipation, which causes the furnace wall of the boiler to still have a certain temperature. The temperature on the furnace wall of all relatively backward boilers is higher. The sootblower is directly installed on the boiler with a very high furnace wall temperature. The high temperature will be transmitted to the sootblower, which will affect the safe use of the sootblower. In addition, the position of the nozzle of the sootblower in the prior art is basically not very convenient for position adjustment, which limits the functionality of the sootblower.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies.

[0005] Therefore, in order to solve the above problems, the utility model provides a furnace soot blower. Utility Model Content
