[0002] A boiler is an energy conversion device. The energy input into the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives, or can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. A boiler that provides hot water is called a hot water boiler, which is mainly used for life and also has a small number of applications in industrial production.

[0004] Although there are many benefits in the above scheme, there are also the following disadvantages: 1. The water flow drives the blades to rotate, so that the shovel can move downward quickly, thereby scraping off the scale on the inner wall of the waste heat absorption chamber. However, the way in which the water flow drives the blades to rotate makes it difficult to move the shovel downward under the limiting action of the reset spring, and it may even be impossible to scrape off the scale on the inner wall of the waste heat absorption chamber; 2. If the scale after scraping is large, it is difficult to remove it from the waste heat absorption chamber, which reduces the practicability of the device. Utility Model Content
