【正文】 er the normal parameter relation between. While steam, water flows through the smuggling of succoth bundle tail water cooling section special bundle erosion hazard is great. In addition, this two phase flow will also serious scour hydrophobic pipelines and accessories, and causes vibration of succoth, especially pipe elbow and scanty water regulator damage is bigger. Therefore, the plants should be prohibited from running without water. Longterm Automatic adjustment can meet various thermal running condition, ensure and improve regulation performance TouRuLv, and run automatically personnel should be strengthening supervision, once hydrophobic automatic adjusting device cannot be automatically maintain water level, should maintain manual adjustment. (2) strengthening the trap flow area. If the original design general trap flow area is too small, or due to high temperature and succoth spent sparsely decorated not reasonable cause conduit of pressure drop too ambassador scanty water vaporizing in flow caused by the hydrophobic stagnation, also can consider widening scanty water regulator window area. (3) change the position of the trap. Will the high add trap loaded to scanty water into the next equipment, such as near the entrance of the high add trap by zero meters layer moved deaerator platform, to prevent scanty water vaporizing in the pipe of the three mon fault caused a role. (4) slow to scanty water piping elbows of erosion. For existing scanty water pipe especially elbow eroding of the damage, can be in the pipeline and all after regulator in the elbow wall thickening hydrophobic pipe, elbow still can use local dilatancy deceleration or liner tube, with 90 176。 There will be in operation by the unit loads of mutation, pump failure, bypass switching caused the sudden pressure and temperature, these would give high add damage. Therefore, in addition to the high add design, manufacture and installation must ensure that quality outside, still in operation and maintenance etc, and take the necessary measures to ensure the longterm safety of operation of high added.2. the existing problems In order to ensure the safety of coalfired power plants ManFa, each high economic add all should is in operation. If because of the failure, should according to GaoJiaShi must be discontinued with specified high manufacturing Numbers and discontinuation of relationships, or according to the load to determine the steam extract
