Product Description
Prroduct Description
The water wall of the large boiler is basically a membrane wall, which has the advantages of simplicity, steel saving, good thermal insulation and good air tightness. A number of finned tubes are welded longitudinally to form a single water wall heating surface, thus forming a membrane water wall. The size of each component is welded according to the requirements of the circulating loop pipe group, and the group is then sealed with welding between the group during installation, so that the furnace is tightly surrounded by a whole layer of water-cooled wall diaphragm, therefore, this water-cooled wall is often called a membrane water-cooled wall.
Advantages of membrane water walls
(1) Ensure the tightness of the furnace wall and reduce the air leakage of the combustion chamber.
(2) The combustion chamber is fully water-cooled, which is conducive to preventing coking in the case of intensified combustion.
(3) The heat storage capacity is small, the combustion chamber heats up quickly, and the cooling is also fast, which can shorten the cooling time of boiler start-up and shutdown.
(4) It is suitable to use the pipe-laying furnace wall, which greatly reduces the load of the boiler frame and is convenient for suspension.
(5) Compared with the plain tube, the heat absorption capacity of the tube is improved.
(6) It improves the degree of pre-assembly of boiler parts, which is convenient and reduces the installation workload.
Functions
(1)Improve combustion efficiency
The high temperature gas produced by combustion in the boiler furnace will be cooled through the water wall, and the water wall pipe will make the combustion process more complete by absorbing the heat released by the high temperature gas, thus improving the combustion efficiency.
(2)Control emissions
The role of the water wall also includes controlling the emission of harmful substances such as nitrogen oxides and sulfides produced during the combustion process of the boiler, making the chemical composition of the flue gas more stable and reasonable.
(3)Protect the boiler wall
The water wall can effectively reduce the temperature of the inner wall of the boiler furnace, reduce the time and opportunity of direct contact between the boiler wall and high temperature gas, and thus greatly extend the service life of the boiler
Classification
According to the different manufacturing processes, there are three types of membrane water cooling walls:
(1) The first one is welded in rows with rolled fin tubes, and the welding workload is small, but the fin tubes are expensive.
(2) The plain tube and fin (flat steel) are welded in rows, the material cost is low, and it is easy to meet the requirements of a variety of pitches, but the flat steel has high precision requirements and requires finishing equipment.
(3) Plain tube sintering welding, the inter-pipe fin is formed by the welding wire melting and filling, which is mostly used for the pipe screen with a small inter-pipe pitch. The inter-tube pitch of the membrane water wall is related to the boiler pressure, furnace heat load and other factors, and the general s/d is 1.2~1.5.
