[0001] The invention relates to the field of boilers, and in particular to a reciprocating self-heating circulation boiler. Background Art

[0002] As an important strategic energy resource in Southwest my country, sulfur anthracite plays a vital role in the industrial and economic development of the region. Anthracite has a high fixed carbon content and a low volatile yield. It does not smoke when burned, has a short flame with little smoke, and does not coke, which makes it a clean and efficient energy source.

[0003] When the current boiler burns high-sulfur anthracite, the ash produced contains a large amount of ash and sulfur. These substances form sulfates or sulfites through a series of chemical reactions under high temperature conditions. If the ash inside the boiler is not cleaned in time, the sulfates or sulfites will melt under high temperature and adhere to the heating surface or the inner wall of the flue. The ash with oxides such as calcium and silicon as the main components will be captured and adhered by the molten sulfate and gradually grow to form a growth bridge between the tube bundles, thereby causing ash sticky pollution on the boiler heating surface and reducing the boiler's working efficiency.
