They can also reduce boiler efficiency, restrict water circulation and lead to serious mechanical and operating problems. Scale causes the tubes metal temperature to rise, which increases the flue gas temperature. In extreme cases, the tubes fail from overheating. Remember, one millimetre of scale build-up can increase fule consumption by two ...

3 Things You Can Do To Increase Boiler System Efficiency

This results in increased efficiency. Lower temperature gas is ideal, because the higher the temperature, the more energy will be captured as heat by the flue gas. On average, a 22 degree Celsius drop in temperature can result in a one percent increase in efficiency. Another typical issue arises when you are feeding your boiler insufficient air.

Maintaining High-Efficiency Finned Copper-Tube Boilers

Routine boiler maintenance should be performed at the beginning of each heating season or every six months for a boiler in continuous service. A basic inspection and cleaning program can increase the service life of the boiler and reduce maintenance costs. References: *National Fuel Gas Code, 1999 Edition, ANSI Z223.1-1999, NFPA 54-1999

Consulting - Specifying Engineer

9/23/2019 · A commercial hydronic boiler can be either a fire- or water-tube boiler. Water-tube boilers consist of water flowing through tubes that are encased by hot combustion gases. Conversely, fire-tube boilers consist of hot combustion gases passing through tubes surrounded by water.

Industrial Combustion Boilers - IEA-ETSAP

valves can also increase efficiency. Fire-tube boilers can have turbulence promoters inserted into tubing to increase heat transfer. This may result in an additional 1%-2% (typically 1%) efficiency. Oxygen trim controls are used to ensure an optimal fuel/oxygen mix in the burner, with a 1% increase in efficiency [5] [6]. The US Department of

Boiler Combustion

One technology that offsets the efficiency loss due to lower flame temperatures in a firetube boiler is flue gas recirculation. Although the loss of radiant heat transfer could result in an efficiency loss, the recirculated flue gases increase the mass flow through the boiler – thus the convective heat transfer in the tube passes increases.

The boiler is better able to respond to large loads as the ‘low fire’ position will ensure that there is more stored energy in the boiler. If the large load is applied when the burner is on ‘low fire’, it can immediately respond by increasing the firing rate to ‘high fire’, for example the purge cycle can be omitted.
