Jun 26, 2017 · The supplemental alkalinity requirement is, therefore, 20 ppm minus 15 ppm = 5 ppm required as calcium carbonate. Dividing 5 ppm by 50 (equivalent weight of calcium carbonate) gives 0.10 epm caustic soda (as active), or 0.20 epm as 50% active.

dosage to provide a feedwater or boiler water residual. Sodium Sulfite Example The reaction rate is: 2Na 2SO 3 (7.88 ppm) + O 2 ( 1 ppm) o 2Na 2SO 4 For the residual, 1.6 ppm Na 2SO 3 will yield 1 ppm SO 3. The total calculation equation to remove residual oxygen and provide a boiler water residual is

boilers and thereby reduces clean-downs. Dosing Instructions Normal dosage is 20ml daily/tonne of boiler water capacity. Typically this equates to 0.1-0.3 litres/day. This is the recommended initial dose. BOILER COAGULANT should be dosed directly to the boiler via the bypass pot feeder installed in the boiler feed water line. 25 Litres

Boiler – Fundamentals and Best Practices

Boiler Water Treatment Chemical Guidelines—Part Il continued Because of the associated corrosion problems, chelants are not the preferred treatment choice. However, if the system dictates the use of chelating agents, it can feed under "starvation" conditions, i.e., no free residual in the boiler. Based on the trace level of hardness in the boiler
