Background
the utility boiler is an important component of a thermal power plant, the reliability and the high efficiency of the operation of the boiler are practically improved, and the reduction of the unplanned shutdown of the boiler is an important part of the overall process management of power generation equipment. In the operation process of the power station boiler, each heat exchange surface inevitably has an ash and dirt phenomenon, and along with the extension of the operation time, the fouling of the heating surface, which forms slag bonding and coking, becomes more serious and causes heat exchange loss. Because the water-cooled wall has the largest chance of directly contacting with fuel and flame, the slagging phenomenon is most easy to occur and mainly appears as slagging and coking which are difficult to remove; meanwhile, the heating surface of the water-cooled wall is easy to cause circular cutting erosion corrosion and high-temperature corrosion, and coking and corrosion of the water-cooled wall cause great influence and economic loss on the safe operation of the boiler. Slagging and corrosion of the heating surface in the boiler of the coal-fired power plant are common problems which are difficult to effectively solve. In recent years, this problem has become more acute in many power stations in our country due to deterioration of coal media and regulatory factors.
The boiler in operation has no way to carry out timely slag removal and very effective on-line monitoring. Cleaning and inspection maintenance of boiler waterwalls can only be performed during shutdown operations. The coking and accumulated slag cleaning of the water wall pipe wall during the maintenance stopping period not only is an effective measure for improving the heat transfer efficiency of the water wall and reducing the exhaust gas temperature of the boiler, but also is the prepositive work before the water wall is further detected and maintained.

The existing water wall cleaning scheme mainly adopts a scaffold platform erected in a full hearth or a large lifting platform erected, peripheral fire-fighting water is utilized, and a large high-pressure flushing water vehicle is equipped to flush from top to bottom layer by layer from the upper part of the hearth.
When the washing machine is used for washing, a washing person needs to tie a safety belt, hang the safety belt on a safety rope, wear anti-skid shoes and rain-proof clothes, hold the high-pressure water pipe with two hands, and wash the washing machine by a mode of matching the two people, so that the washing machine not only needs to drop the high-pressure water pipe on the wall surface, but also needs to pay attention to the washing effect all the time and burn the wall surface to hurt people. In the washing process, the positions of the lifting platform and the high-pressure water pipe are required to be noticed at any time, so that the high-pressure water pipe is prevented from being damaged by the lifting platform. The whole flushing process has severe working environment and prominent potential safety hazard.
In addition, because a manual cleaning mode is adopted, the flushing track cannot be ensured to be continuous, and more residual ash residues are left after flushing; the water consumption for washing is large, and the slag water treatment amount is also large.
