2019-12-21 · Even the most sophisticated high-temperature and pressure watertube boiler can be simply described as pressure parts (drums, headers, and steel tubes) which contain high-pressure steam and water. The tube surface transfers heat to the water from a fuel being combusted in a controlled manner outside of the tube surface.
Whatever the type of fuel being fired, all high pressure boilers are bound to have a tube failure during the course of their working life. Did you know that a single tube failure in a 500 MW boiler requiring four days of repair work can result in a loss of more than $1,000,000 apart from the generation loss?
