Heat Transfer Studded Water Wall Panels Industiral / Power Station Plant Using
Product Introduce
Studderd water wall panels also known as barbed tube type water wall.It is the circular steel with certain length welded on smooth pipe surface according to the requirement, use pin to be able to lay firmly on water cooling wall fireproof coating, with regard to forming defend combustion belt, liquid discharge slag furnace slag pool and melting slag section, and cyclone furnace cyclone barrel.The water cooling wall of the inner threaded pipe is a pipe with single or multiple spiral grooves cut out on the inner wall of the pipe.The inner threaded pipe is used in the high heat load area or the water wall pipe section with high vaporization rate in the furnace of natural circulation boiler for dc boiler and subcritical parameter forced circulation boiler.When the working medium flows in the inner threaded pipe, strong disturbance occurs, which causes the water pressure in the soda mixture to the pipe wall, and forces the bubble out of the wall surface to be carried away by water, thus damaging the formation of the vapor film, preventing the deterioration of boiling heat transfer, and reducing the temperature of the water-cooled wall pipe wall.
Double-side exposure water wall refers to the water wall arranged along the furnace height in the furnace chamber space to absorb radiant heat on both sides.Used in large capacity boilers.Water wall materials are generally carbon steel.Part of the boiler pressure above 14 mpa is also made of alloy steel.Pipe diameter: natural circulation boiler generally used 51 ~ 83 mm;Multiple forced circulation boilers and dc boilers are generally used 22 ~ 60 mm.The water wall of a dc boiler is not necessarily vertical as in a natural circulation boiler, but can also be horizontally surrounded or in other forms.When the parameters are high, especially in the dc boiler, in order to prevent heat transfer deterioration in the high heat load area of the furnace, internal threaded pipe or spoiler is often used in the pipe.
Advantages
(l) ensure the sealing of furnace wall and reduce air leakage in combustion chamber.
(2) realize full water cooling in the combustion chamber, which is conducive to preventing coking under the condition of intensified combustion.
(3) low heat storage capacity, fast heating and cooling of the combustion chamber, which can shorten the cooling time of the boiler starting and stopping.
(4) it is suitable to use tube-laying furnace wall, which greatly reduces the load of boiler frame and facilitates suspension.
(5) compared with the light pipe, the heat absorption capacity of the pipe is improved.
(6) improve the pre-assembly degree of boiler components, facilitate and reduce the installation workload.
