Adavantages of Water Wall Panel
1.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.
Production Description
In a water - tube boiler, the waterwall is basically the furnace wall made up of refractory material and tubes. The tubes are spaced out evenly and usually link up to headers. These headers then connect back to the main part of the boiler where steam gets generated.
So, what’s the deal with waterwalls? They’ve got two big jobs. First, they soak up heat that would otherwise just float away into the air, using it to warm up the water inside the boiler. Second, they keep the refractory material cool. Why’s that important? Well, it stops the refractory from cracking and breaking apart, which is called spalling.
