Abstract
The utility model relates to a water-fire tube heat tube shell boiler, which is to solve the problem of high temperature side tube plate crack, and thereby, the service life of the boiler is extended. The thermal efficiency of the boiler is improved simultaneously, and the utility model is favorable for smoke prevention and dust control. The boiler is mainly composed of parts of a convex shell cover, a barrel body, a thread smoke pipe, a water pipe, a heat pipe, etc. The utility model is suitable for a water heating boiler and a steam boiler.
Description
The present invention relates to the boiler manufacturing technology, is a kind of extreme misery pipe, heat pipe shell boiler specifically.
Horizontal package boiler is from the sixties, use so far, progressively perfect, but the tube sheet on high temperature side crackle is its deadly defect, and former for this reason Ministry of Labour once sent the documents, and did not solve tube-plate fracture, this type of furnace must not be produced again, after serve producer and change flat tube sheet into the convex tube sheet, change smoke pipe into helix tube, but tube-plate fracture still has generation.
The purpose of this utility model is to want to provide a kind of extreme misery pipe, heat pipe shell boiler, solves the tube sheet on high temperature side crackle, and the problem in prolonged boiler service life improves boiler thermal output simultaneously, helps smoke abatement and dust control again.
The technical solution of the utility model is as follows, and the tube sheet on high temperature side crackle mainly is because cigarette Wen Taigao and water treatment are bad, causes smoke pipe and the fouling of tube sheet contact site serious, and fouling back tube sheet heat transfer conditions worsens more, causes hot-spot, cracks.Play a major role so reduce tube sheet on high temperature side cigarette temperature, concrete scheme is as follows: in the drum lower boreholes of high temperature side, several heat pipes are installed, heat pipe condenser section stretches into drum inside, heat pipe evaporator section contact high-temperature flue gas.
Advantage of the present invention is: heat pipe can absorb high-temperature flue gas, improves the thermal efficiency, thereby reduces the temperature of tube sheet on high temperature side, generally can reach below 750 ℃.Because stopping of heat pipe makes a part of flying dust sedimentation, helps environmental protection.If do not adopt heat pipe, certainly will increase radiation of burner hearth, heating surface or increase the comb heating surface again, master-plan also is difficult to arrange.
Below in conjunction with accompanying drawing, be further explained.
Figure one is a structural representation of the present utility model.
From figure one as can be known, constitute shell by convex end socket 1 and cylindrical shell 2, heat pipe 3 is installed in the shell bottom of high temperature convex end socket one side, high-temperature flue gas enters threaded flue 4 through superheater tube, the shell both sides, be welded with water pipe 5, chimney arch 6 etc. is arranged in the burner hearth, also have the universal component of other water fire tube shell boiler.
Claims (1)
- A kind of extreme misery pipe, heat pipe shell boiler, mainly form by the universal component of water fire tube shell boilers such as convex end socket, cylindrical shell, threaded flue, water pipe, it is characterized in that: in the drum lower boreholes of high temperature side, several heat pipes are installed, heat pipe condenser section stretches into drum inside, heat pipe evaporator section contact high-temperature flue gas.
