2019-5-11 · One of the hot gases produced in the combustion process is water vapour (steam), which arises from burning the hydrogen content of the fuel. A condensing boiler extracts additional heat from the waste gases by condensing this water vapour to liquid water, thus recovering its latent heat of vaporization. A typical increase of efficiency can be
2019-5-13 · A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications,[1][2] including water heating, central heating, boiler …
2019-5-14 · The purpose of a deaerator is to reduce dissolved gases, particularly oxygen, to a low level and improve a plant's thermal efficiency by raising the water temperature. In addition, deaerators provide feedwater storage and proper suction conditions for boiler feedwater pumps.
Effects of Presence of Dissolved Gases in Feed Water
The most harmful of the dissolved gases is oxygen, which can cause pitting of metal. Very small amount of oxygen can cause severe damage, a mixture of oxygen and water is a highly corrosive combination. This corrosive nature doubles with every 18 deg. F increase in temperature.
2006-9-29 · Dry flue gases losses are typically 4% or greater depending on exit flue gas temperature. This loss is caused by the heat carried out by hot nitrogen, carbon dioxide, sulfur oxide and excess oxygen. The amount of energy wasted by dry flue gases depends on the amount of excess air used for combustion and the final boiler exhaust temperature [1].

2019-3-13 · Wet Scrubbers are the pollution control devices usually installed in the path of the flue gases to extract Sulfur compounds or oxides of sulfur such as Sulfur Dioxide (SO 2) and Ash particles. Wet Scrubbers are called so because of the scrubbing action of gases in contact with water to scrub off dirty particulates or gases that cause air pollution.
A properly sized furnace or boiler will operate most efficiently, and you'll want to choose a dependable unit and compare the warranties of each furnace or boiler you’re considering. When shopping for high-efficiency furnaces and boilers, look for the ENERGY STAR® label.
Application Note: Flue Gas Analysis as a Boiler Diagnostic
2018-12-26 · Flue Gas Analysis as a Boiler Diagnostic Tool Overview, and Traditional Application Combustion flue gas analysis has been used by Power Plant Operators for decades as a method of optimizing fuel/air ratio. By measuring the amount of excess oxygen and/or CO in the flue gases resulting from combustion, plant operators can operate at the best

Specific contaminants such as ammonia or sulphur bearing gases may increase attack on copper alloys in the system. Corrosion is caused by the combination of oxide layer fluxing and continuous oxidation by transported oxygen. Cracking in boiler metal may occur by two different mechanisms.
