Boiler tube removal can be an extremely difficult process, and the method used will vary depending on the application. The amount of expansion as well as the age of the tube and whether or not it was ...

Reducing boiler downtime – particularly from tube failures – demands constant vigilance. Boiler tube failures, especially in coal-fired power plants, continue to be the major cause of boiler forced ...

Confined spaces are one of the most common challenges boilermakers face during tube installation and maintenance. From squeezing into drums to working in tight utility rooms, space constraints are ...

One of the big surprises facing plants that switch from a more or less standard bituminous coal to a western coal is the increase in slagging and fouling. Many plants have reported significantly more ...

A water wall boiler tube repair system for biomass boilers that precisely cuts tube panels without a HAZ (heat affect zone) and bevels for superior welding end preps has been introduced by Esco Tool ...

Faced with deregulation, increasing retail competition and pressures to keep boilers online, many coal-fired power generating stations have adopted business strategies centered on increasing unit ...

Scale, like many things in life, is easy to ignore until it becomes a problem. For boilers that produce hot water and steam for industrial activities, the situation can become serious before the scale ...

Cleaning power station boiler tube walls is a dirty and troublesome job that is not only hazardous, but can generally only be done during station down times to minimize the risk to human cleaners. To ...

Boiler tubes in thermal power plants serve as the critical boundary between high-pressure steam and combustion gases. Their failure can precipitate unscheduled shutdowns, safety hazards and ...
