Hydrogen Damage In Utility Boilers Related Information

Natural Gas Fired Boilers

The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and

Boiler Tube Failure Investigation - TCR Advanced

Boiler tubes. can undergo sudden failures by rupture or leakage and is usually detected while in operation rather than during a hydro test or other inspection activities. This calls for immediate action as it can often cause a shutdown of the boiler, leading to loss of production and downtime. It is critical to understand the various modes and
