SA210A1 carbon steel boiler parts membrane water panel for
industrial fire tube boiler boiler water walls
SA210A1 carbon steel boiler parts membrane water panel Brief Introduction
1. Water walls are the main heating part of boilers, they are
composed of rows of steel tubes, arranged on surrrandings of boiler
furnace.
2. Inside it are flowing water or steam, the outside receive firing
heat of the boiler furnace.
3. They mainly absorb radiation heat by high temperature combusion
products in the furnace, and the working fluid are going up, to be
heated and vaporized.
4. Boiler water walls are membrane walls that are made of tubes
welded together with or without a strip of metal in between.
5. These walls form the enclosure of the coal combustion chamber.
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 boiler.
6. Our membrane water wall are manufactured using high grade raw
material and contemporary production equipment at our advanced
manufacturing unit. The offered range is available in various
sizes, shapes and specifications, as per the requirements of our
esteemed clients. 7. Further, these are delivered to the clients
within promised time frame.
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.
