Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots. Leading to local overheating. Scaling mechanism is the …Get Price

Condensing boilers achieve high efficiencies by recovering the latent heat (approx. 10 – 12% available) from the combustion process. Based on the observations from the effects of excess air on the dew point temperature, closing the window of condensing (condensing mode) would mean eliminating the opportunity to achieve the highest efficiency possible.Get Price
