To achieve these goals, the utility model provides a kind of membrane wall structure of water-tube boiler, comprise chassis, following boiler and last boiler, wherein, be provided with some water screen tubes around the described boiler down, be solidly connected between described water screen tube and the described chassis, further be provided with band steel between the described water screen tube, fastening welding between described band steel and the described water screen tube.
Be solidly connected between described boiler down and the described chassis, following boiler top is provided with the described boiler of going up, described the place ahead of boiler down is provided with preceding collection case, the described left of boiler down is provided with left side collection case, the right-hand right side collection case that is provided with of described boiler down, described water screen tube is connected with described upward boiler, described left side collection case, described right side collection case.
An enterprising step of described boiler down is provided with some convection tubes and communicating pipe, and described boiler down is by described communicating pipe and described left side collection case, and described right collection case is connected, and described boiler down is connected by described convection tube with described going up between the boiler.
Described boiler down top is provided with the flue interface, and described boiler both sides down are provided with blows grey hole.
Described water screen tube and described band steel weld together, and some water screen tubes and band steel have constituted membrane wall structure of the present utility model.
Advantage of the present utility model is, and is simple in structure, easy to use, can effectively reduce the installation cost and the complexity of water-tube boiler, avoids the boiler hot loss of energy, improves the water-tube boiler thermal efficiency.Specific as follows:
1, water screen tube of the present utility model and band steel weld together, and some water screen tubes and band steel have constituted membrane wall structure of the present utility model.So, the heat that good airproof performance of the present utility model, boiler heat pass water screen tube arrival furnace wall is little, and the furnace wall accumulation of heat is less; Heat is absorbed by band steel, and band steel is given water screen tube or boiler with heat radiation again, reduces heat-energy losses, improves the thermal efficiency.
2, membrane wall structure of the present utility model causes the furnace wall accumulation of heat less, so, when mounted, can avoid building thick furnace wall, and simultaneously, saving maybe can be less with being provided with without refractory material.Reduce cost, reduce installation cost, reduced the installation complexity.
