Soot blower for chamber-combustion water tube pulverized coal fired boiler

Abstract

A soot blower for a chamber-combustion water tube pulverized coal fired boiler comprises a soot blowing tube, a joint ring, asbestos ropes, a seamless steel tube sleeve, a front pressing cover, front padding, a seamless steel tube shell, a shaft, a rear pressing cover, a sprocket, rear padding and a middle tube. The soot blowing tube is connected with the joint ring through the middle tube, the front of the middle tube is provided with the seamless steel tube sleeve, the middle of the middle tube is connected with the chamber-combustion water tube pulverized coal firing boiler through the seamless steel tube shell, the front padding is disposed between the seamless steel tube shell and the middle tube, the front padding is provided with the front pressing cover at the front end, the seamless steel tube shell is connected with the shaft at the rear end, the shaft is provided with the rear pressing cover, and the shaft is provided with the sprocket at the tail end. The soot blower of the chamber-combustion water tube pulverized coal firing boiler is simple in structure, reliable to use and thoroughly effective in soot blowing, the defect of soot deposition caking on the outer surface of a convection tube bundle can be overcome thoroughly.

Description

technical field [0001] The invention relates to a soot blower, in particular to a soot blower for a chamber-fired water tube pulverized coal boiler. Background technique [0002] At present, traditional pulverized coal boilers and water-tube steam boilers generally have the disadvantages of high energy consumption, high power consumption, high smoke and dust emissions, and low thermal efficiency, and continue to undergo technological transformation and upgrading. [0003] Traditional chamber-fired water-tube pulverized-coal boilers are prone to ash scaling on the outer surface of the convection tube bundles, affecting the heat transfer capacity of the boiler. Therefore, a soot blower is urgently needed to solve the above problems. Contents of the invention [0003] The main purpose of the present invention is to provide a soot blower for a chamber-fired water tube pulverized coal boiler. Scaling is a technical problem that affects the heat exchange capacity of boilers. ...
