2019-12-4 · The device, illustrated in Figure 14-4, was developed by the United States Bureau of Mines. If boiler water possesses embrittling characteristics, steps must be taken to protect the boiler from embrittlement-related failure. Sodium nitrate is the standard treatment for inhibiting embrittlement in boilers operating at low pressures.

Tube Failures in High Pressure Boilers

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?

Common Boiler Problems, Part 1: Low Water Conditions

The only thing that allows a boiler to withstand these furnace temperatures is the presence of water in or around (depending on whether the boiler is a fire tube or a water tube design) the pressure parts at all times that a fire is present.
