Boiler Component Carbon Steel Membrane Water Wall for CFB Boiler
Boiler component carbon steel membrane water wall for CFB boiler is main radiation heat surface, arranged inside the boiler chamber and proceeds the heat exchange directly with the high temperature flame. The convection tubes are the convection heat surface of the boiler, arranged between the boiler chamber outlet and the end heat surface and proceed the heat exchange directly with the high temperature fume. The water wall and convection tubes are the main heat surface of the boiler, the tubes diameter for both Generally used φ51~60mm boiler streel tubes, also as the request.
Boiler component carbon steel membrane water walls for CFB boiler are membrane walls that are made of tubes welded together with or without a strip of metal in between. These walls form the enclosure of the coal combustion chamber. Membrane water wall tubes are also referred to as the evaporator section; they contain water mostly in liquid form which gradually evaporates as it rises in the steam boiler.
Advantages of Membrane Water Wall
1). To guarantee the leakproofness of furnace walll 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 steam boiler membrane water wall panel improves the heat absorption capacity of tubes.
6) Boiler component carbon steel membrane water walls for CFB boilercould improve the preliminary combination degree of boiler parts and reduce the installation workload.
