Boiler System - Tips on a chemical program for your boiler system | Bond Water Technologies, Inc.

Boiler System – Tips on a chemical program for your boiler system. Most boiler systems today burn natural gas as the primary fuel. Many systems are also set up to burn an alternate fuel if the natural gas supply is curtailed or cut off. In most cases, the alternate fuel is No. 2 fuel oil, a light distillate that is the same as diesel fuel.

Feed Water Treatment to Avoid Corrosion - Engineering ToolBox

Make-up water to steam boilers should be treated with oxygen scavengers to avoid serious corrosion problems. Corrosion is a major problem in steam systems with high consumption of make-up water. Fresh water contains dissolved oxygen. Oxygen together with high temperature is highly corrosive for the carbon steel piping used in steam systems.

4/5/2016 · Theoretically, it takes about 8 ppm of sodium sulfite to react with 1 ppm of oxygen. To assure that this reaction goes to completion and that all oxygen is removed, an excess of 30 to 70 ppm of sulfite should be carried in the boiler water. To eliminate oxygen corrosion and assure that the sulfite/oxygen reaction is complete before the feedwater reaches the boiler, sulfite should be fed as early as possible …
