Improving Energy Efficiency of Boiler Syste
The boiler suppliers and sales personnel will often cite various numbers, like the boiler has a thermal efficiency of 85%, combustion efficiency of 87%, a boiler efficiency of 80%, and a fuel-to-steam efficiency of 83%. What does these mean? Typically, 1) Thermal efficiency reflects how well the boiler vessel transfers heat. The figure usually

Top 10 Boiler Problems - Boulden Brothe
Cause: Air in the system is usually the cause of strange banging or whistling noises from your boiler (though low pressure and kettling can also be at fault). A pump failure will generate many strange noises of its own. Fixes: Bleed your radiator or get a power flush of the pipes. This should remove excess air from the system.

Causes for Flame Failure in a Boiler and Operator Acti
Maintaining a good flame in a boiler is the key to a good boiler performance. Unstable flame is always a threat for boiler furnace explosion, which can lead to a large outage of boiler and loss. There are many causes that can contribute to boiler flame failure. Hence it has become a practice of all boiler designers to interlock purging the boiler with boiler start-up.

hold the air to fuel ratio. Burners with low quality damper designs and complex linkage assemblies tend to be more difficult to set-up over the firing range of the boiler and tend to be unable to accurately hold the air to fuel ratio as the boiler operates. Why choose the most efficient boiler? Because the dividends paid back each year far outweigh

Common Boiler Problems, Part 1: Low Water Conditio
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. Low water conditions will literally melt the steel pressure parts.

Troubleshooting a Gas-Fired Hot Water Boil
The boiler has no power: The circuit breaker or fuse controlling the furnace may have tripped or blown. Reset the tripped circuit breaker or replace a blown fuse. Water level low: Maintain water level in the boiler at half-full.The boiler's automatic filling system, controlled by the pressure-reducing valve, should maintain the proper water level at 12 to 15 psi of pressure.
