ASME Standard Customized Specification Pin Type Boiler Water Wall Panels Water Wall Tubes In Boiler
Product Description
It is also called bayonet water wall. It is required to weld a certain length of round steel on the surface of the bare tube, and use pins to lay refractory coating firmly on the water wall to form a fire protection belt, a slag pool and a slag melting section for liquid slag discharging furnace as well as a cyclone drum of the cyclone furnace.The water wall of inner threaded pipe is a pipe with single or multiple spiral grooves on the inner wall of the pipe. Internal threaded tubes are used in the high heat load zone of once-through boilers,sub critical parameters and forced circulation boilers or in the water wall sections with high vaporization rate. When the working fluid flows in the inner threaded tube, strong disturbance occurs, which causes the water pressure in the steam water mixture to the tube wall and forces the bubbles away from the wall to be carried away by the water, thus destroying the formation of the wapor film, preventing the boiling heat transfer from deteriorating, and lowering the temperature of the tube wall of the water wall panel.

Advantages of Membrane Water Wall
1). To guarantee the leakproofness of furnace wall and reduce the air leak of combustion chamber.
2). To achieve the full water cooling of combustion chamber, and the boiler accessories membrane water wall is benefit to prevent coking under the condition of supplemental firing.
3). The thermal storage capacity is small, the warming of combustion chamber is fast and the cooling is also fast, which could shorten the cooling time of boiler’s start and furnace shut down.
4). It is good to adopt top supported water cooled wall and it could reduce the load of boiler framework, which is benefit to overhang.
5) Compared with the bare tubes, the membrane water wall improves the heat absorption capacity of tubes.
6) The factory direct boiler membrane water wall could improve the Preliminary combination degree of boiler parts and reduce the installation workload.
