Clean Boiler Waterside Heat Transfer Surfaces

Aboiler annually uses 450,000 million Btu (MMBtu) of fuel while operating for 8,000 hours at its rated capacity of 45,000 pounds-per-hour (lbs/hr) of 150-psig steam. If scale 1/32nd of an inch thick is allowed to form on the boiler tubes, and the scale is of "normal" composition, the table indicates a fuel loss of 2%.

Boiler tube scale deposit measurement reduces energy cost

Feb 02, 2016 · and a fuel cost of $2.50/MMBTU, the resulting annual cost of lost energy is $100,000. An indirect indicator of scale or deposit formation is flue gas temperature. If the flue gas temperature rises (with boiler load and excess air held constant), the effect may be due to scale in the tubes. Effective and well timed boiler tube scale deposit

How Our Boiler Water Treatment Systems Can Eliminate Scale. As mentioned, the accumulation of scale creates an insulating effect. This insulation can ultimately result in the warping and rupture of the boiler tubes. Scale can also reduce heat transfer and efficiency, which can lead to an increase in fuel bills.
