Polymer heat exchanger design for condensing boiler …

Condensing boilers achieve very high efficiency levels by recovering both sensible heat and water vapor latent heat from the flue gas. Research since the 1980's has focused on corrosion in such condensing heat exchangers related to the acidic condensate and material selection.

Boiler Vs Water Heater: What's The Difference? | Water …

9/7/2021 · A system boiler does not require a cold water tank but a hot water tank. The water comes directly from the main tank and is then heated and stored in your cylinder. Its size limits hot water capacity – there are options for this – and if it runs out, you will have to wait for the cold water to be heated and stored again.

Boiler Scale Inhibitors | ChemTreat, Inc.

Boiler water polymers function as dispersants and weak sequestrants. Phosphate chemistry works by precipitating calcium as any of several insoluble calcium phosphate compounds. This material can deposit on tube and drum surfaces, and its buildup can impede heat transfer on generating tubes and cause tube failures.

Module 182: Aspects of primary circuit design for …

The basic performance of condensing boilers is directly associated with the temperature of the water entering the boiler's condensing heat exchanger, as graphically illustrated in Figure 1. The lower return-water temperatures available from variable volume systems are particularly useful when condensing boilers are used, as their efficiency increases with lower return-water temperature.

Clarification | CleanBoiler.org

Polymers used for charge neutralization cannot be over-diluted or over-mixed. The farther upstream in the system these polymers can be added, the better their performance. Because most polymers are viscous, they must be properly diluted before they are added to the influent water.

Polymer heat exchanger design for condensing boiler …

25/6/2016 · The results indicate thermal conductivity values of stainless steel do not need to be achieved for similar sensible heat recovery performance and high boiler efficiency. An increase in thermal conductivity from 5 to 10 times is needed; therefore a low value thermal conductivity value of approximately 2.5 W/m⋅K would be adequate.

Water Handbook -Boiler Deposits: Occurrence And …

The need to provide boilers with high-quality feedwater is a natural result of the advances made in boiler performance. The ratio of heating surface to evaporation has decreased. Consequently, heat transfer rates through radiant water wall tubes have increased-occasionally in excess of 200,000 Btu/ft²/hr.
