Title:
SOOT BLOWER DEVICE AND BOILER
Document Type and Number:
WIPO Patent Application WO/2019/131334
Kind Code:
A1
Abstract:
Provided is a soot blower device (31b) that removes ash by ejecting a spray medium toward banks (7-10) in which horizontally-oriented heat transfer tubes (21) are stacked in the vertical direction and a plurality of the heat transfer tubes (21) are aligned in the lateral direction. The soot blower device (31) is characterized by the following: blower nozzles (32) are installed above and below the banks (7-10) so as to be capable of moving in the horizontal direction; the heat transfer tubes (21) are finned heat transfer tubes (21) provided with fins (23b); and a blower nozzle (32b1) above the banks (7-10) and a blower nozzle (32b2) below the banks (7-10) are disposed so as to move through positions which are deviated from each other within the horizontal plane. Due to this configuration, when removing ash from all of the heat transfer tubes, a decrease in the ash removal efficiency is suppressed and wear of the heat transfer tubes is suppressed.
