Corrosion is the principal effect of dissolved carbon dioxide. The gas will dissolve in water, producing corrosive carbonic acid: H 2 O + CO 2 çè H 2 CO 3 çè H + + HCO 3-. The low pH resulting from this reaction also enhances the corrosive effect of oxygen. In boiler systems, corrosion resulting from carbon dioxide is most often encountered

8/1/2016 · The AFUE rating for an all-electric boiler is between 95% and . However, despite their high efficiency, the higher cost of electricity in most parts of the country makes all-electric boilers an uneconomic choice. The minimum AFUE rating requirements for boilers varies based on the type of fuel and the heating medium used.

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.

What it is: CO is the result of incomplete combustion. The goal of burner/boiler design is to achieve complete combustion in order to release all of the energy available in the fuel. If some carbon molecules cannot find some oxygen molecules, they will partially convert to CO (carbon monoxide) rather than CO2 (carbon dioxide).

The "ref. 3% O2" is required as a benchmark for the oxygen content in the flue gas. This is because the boiler will operate at various O2 levels, and the air district needs to normalize the measurements. Sometimes, emission limits are referenced with different O2 levels for equipment in the same plant.

4/5/2016 · Sulfite is added to boilers to remove dissolved oxygen, which causes severe pitting corrosion. 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.
