Erosion-corrosion effects were studied on simulated steam tubes (400–700 F, 204–370 C) oriented either horizontally or vertically in the bed. Results of 50-hr tests showed that the life of heat exchange tubes operating up to 650°F (343°C) in this type of combustor will depend primarily on erosion effects.Get Price
temperature erosion–corrosion of heat exchanger tubes and other structural materials in coal-fired boilers is recognised as the main cause of downtime at power-generating plants, which could account for 50–75% of their total arrest time.Get Price

Hard particles, such as sharp edged quartz crystals, cause erosion wear when colliding on convective heat exchanger tubes and on the rear wall of the steam boiler. The most important ways to reduce erosion wear in steam boilers is to keep the velocity of the flue gas moderate and prevent channelling of the ash flow in a certain part of the cross section of the flue gas channel, especially near Get Price

Fly ash erosion is the second most important cause for boiler tube failure (DOE, 1998). Tube failures by erosion in some cases account for about one-third of all tube failures in a boiler. Studies on erosion show that the average rate of reduction in metal thickness of eroding tubes in pulverized coal fired (PC) boilers varies from 2.0 × 10 -5 µm/s to 15 × 10 -5 µm/s.Get Price
Causes: Short-term overheat failures are most common during boiler start-up. Failures result when the tube metal temperature is extremely elevated from a lack of cooling steam or water flow. A typical example is when superheater tubes have not cleared of condensation during boiler start-up, obstructing steam …Get Price
