Protecting coal fired power plants from abrasion wear

Erosion of the pipe network and boiler tubes is a common problem in coal-fired power plants. As fine particles of coal dust, or pulverised coal, pass through the pipe network from the pulveriser mill to the boiler at high velocity, they can cause serious damage to the equipment and wear down the metal surfaces along their flow path. 

For a coal fired power station in Queensland, the answer to some major erosion-related problems came through CBC experts, in collaboration with Henkel Australia. The power station was looking for ways to reduce the time and cost required to repair the barrels, elbows and diffusers passing the pulverised coal from the mills to the boilers, as well as to repair worn-out coal burner tips on site to save time.
