Abstract
The utility model relates to a circulating fluid bed boiler T-shaped finned film type water screen pipe which comprises a water screen pipe and fin plates, wherein the fin plates are connected with adjacent two water screen pipes. The utility model is characterized in that the center line of the fin plate between every other water screen pipes is vertically provided with a steel strip. The utility model has the advantage that the water screen pipe can prevent and improve the serious abrasion problem of the boiler inside water screen pipes fixed in the circulating fluidized bed boilers.
Description
Technical field
The utility model relates to a kind of CFBB T shape fin monowall tube, belongs to CFBB abrasionproof technical field.
Background technology
Because the burning feature of CFBB is different with the conventional pulverized-coal stove, the stove internal heating surface adopts traditional fin panel casing, easily cause the water cooling tube wearing and tearing, the wearing and tearing of circulating fluid bed boiler internal heating surface are the principal elements that have a strong impact on boiler economy, safety, reliability service.
Summary of the invention
The purpose of this utility model be invention a kind of prevent and improve water screen tube heavy wear in the intrinsic stove of CFBB be used for CFBB T shape fin monowall tube.
For realizing above purpose, the technical solution of the utility model provides a kind of CFBB T shape fin monowall tube, comprise water screen tube and fin, this fin connects two adjacent water screen tubes, it is characterized in that, on the fin center line between per two water screen tubes, vertically be provided with a steel bar.
The utility model technology is on the fin of the monowall tube of CFBB, along being welded with a steel bar on the fin center line, become and have T shape fin fin panel casing, to very prevent and improve the water cooling tube wearing and tearing effectively, increase simultaneously the caloric receptivity of evaporating heating surface again, help the startup and the operation of CFBB, to New Product's Design, manufacturing and all easy to implement to the transformation that moves boiler.
The utility model has the advantages that the problem that can prevent and improve water screen tube heavy wear in the intrinsic stove of CFBB.
Description of drawings
Fig. 1 is a CFBB T shape fin monowall tube structural representation;
Fig. 2 is a CFBB T shape fin monowall tube vertical view.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, 2, be CFBB T shape fin monowall tube structural representation, described CFBB T shape fin monowall tube is by water screen tube 1, fin 2 and steel bar 3, fin 2 connects two adjacent water screen tubes 1, on fin 2 center lines between per two water screen tubes 1, vertically be welded with a steel bar 3, its steel bar 3 length are determined by the furnace depth size of burner hearth free board height and roof of the furnace or according to zone easy to wear, width is 35mm-60mm, steel bar thickness 3mm-6mm.
