The amount of chemical fed should be recorded and compared with oxygen levels in the feedwater to provide a check on the control of dissolved oxygen in the system. With sodium sulfite, a drop in the chemical residual in the boiler water or a need to increase chemical feed may indicate a problem.
Heating the boiler for chemical cleaning using an auxiliary boiler or steam from another unit adds complexity and cost to the cleaning.
Boiler Waterside Fouling Scale is one of the most common deposit related problems. Scale is a buildup of solid material from the reactions between the impurities in water and tube metal, on the water-side tube surface. Scale acts as an insulator that reduces heat transfer, causing a decrease in boiler efficiency and excessive fuel consumption.
How to Descale With Muriatic Acid By Shauna Zamarripa. SAVE; Add water to the pool until it is 1 to 2 inches above the scale line. Keep the pool pump on for 8 to 12 hours per day during the cleaning period. It can take 3 to 6 months to effectively descale a pool. The pump helps increase the circulation of the solution and descales the pool
Boiler Scale Steam boiler cleaning is a routine water system maintenance in which deposits like calcium are removed on the boiler surface through the use of a descaling acid. Impurities tend to accumulate in boilers through constant use which can insulate water from the heat source, especially if heat exchangers in the system use tap water.

Oct 11, 2016 · Take a sample of the scale from the boiler and keep for tests. ScaleBreak is added to water in the mixing tank until the boiler is full and water starts to be returned to the mixing tank. Only add enough water and product to the mixing tank to cover pump suction.
Make-up water to steam boilers should be treated with oxygen scavengers to avoid serious corrosion problems. Fresh water contains dissolved oxygen. Oxygen together with high temperature is highly corrosive for the carbon steel piping used in steam systems. To avoid corrosion the oxygen in the make-up water for saturated steam production should be removed by using some kind of scavenger
