Description
Technical Field
The invention relates to a coiled pipe module, and belongs to the technical field of power station boiler equipment.
Background
Serpentine tube modules are an important component of utility boilers. The coiled pipe module comprises a plurality of coiled pipes which are arranged in parallel, and an inlet header and an outlet header which are connected with the coiled pipes. The coiled pipe module is arranged in the flue, when local leakage occurs to the coiled pipe, the former maintenance method is to replace the leaked coiled pipe by a maintenance personnel entering the flue, and the coiled pipe module can only recover to normal work after the coiled pipe module is ensured to be free from leakage. Because the inner space of the flue is closed and narrow, the operation of overhauling and replacing the coiled pipe is very inconvenient, so that the overhauling work is time-consuming and labor-consuming, especially, overhauling personnel cannot enter the flue filled with high-temperature flue gas at all in the operation process of the boiler, and therefore, the overhauling operation can be carried out on the coiled pipe module after the boiler is stopped. The unplanned shutdown of the boiler not only can directly influence the safe and stable operation of the generator set, but also can bring about larger economic loss. Therefore, the technical scheme that overhauling efficiency of the coiled pipe module can be improved and overhauling can be achieved under the condition that the boiler is not stopped is provided for the coiled pipe module, so that the number of times of unplanned stopping of the boiler is reduced, and the method has very important significance.
