To address your question, we will examine the combustion of a simple fuel – methane (CH4). The chemical equation for the reaction of methane with oxygen (O2) is presented below: CH4 + 2O2 → CO2 + 2H2O. In a perfect world, methane will react with oxygen to release energy and form carbon dioxide and water.Get Price
2.2.1 A steam boiler's hydrological cycle (steam generation) is similar to that of the earth's hydrological cycle.

Apr 15, 2008 · Carbon-dioxide removal Acting simultaneously, carbon dioxide and oxygen can be up to 40 percent more corrosive than the same quantities of the two gases acting individually. Ferrous hydroxide is an alkaline compound, with its rate of solution depending on the pH of the water with which it is in contact.Get Price
This, along with the flue gas analysis showing percent oxygen, carbon dioxide and carbon monoxide, will then determine the overall efficiency of the boiler. This is very important because a typical boiler will consume four times its initial cost in fuel, annually, and, in many industrial applications, this means a fuel cost in excess of $1 Get Price
The correct amount of excess air is determined from analyzing flue gas oxygen or carbon dioxide concentrations. Inadequate excess air results in unburned combustibles (fuel, soot, smoke, and carbon monoxide), while too much results in heat lost due to the increased flue gas flow—thus lowering the overall boiler fuel-to-steam efficiency.Get Price

If some carbon molecules cannot find some oxygen molecules, they will partially convert to CO (carbon monoxide) rather than CO2 (carbon dioxide). All burner/boilers are designed to have some "excess air" to reduce the amount of CO made. Why it's controlled: In its gaseous form, CO is a poisonous substance. In solid form it is commonly Get Price
The majority of the combined carbon dioxide is released with the steam in the boiler and subsequently dissolves in the condensate, frequently causing corrosion problems. These problems can be controlled through the use of volatile neutralizing amines, filming amines, and metal oxide conditioners.Get Price

Suppose we start with a 100 parts of natural gas. If this is burned in a boiler the ideal equation approximates to: CH 4 + air (2O 2 + 8N 2) = CO 2 + 2H 2 O + 8N 2 On a dry basis the percentage of carbon dioxide in the in the flue gas is 1/9 or 11.1% (vol.) . This is broadly similar to many natural gases where methane (and some higher Get Price
the temperature difference between the flue gas leaving a boiler and the ambient supply temperature is 300 o C, and; the carbon dioxide measured in the flue gas is 10% - then, from the diagram above. the flue gas loss can be estimated to approximately 16%.Get Price
Oxygen measurement is critical when testing exhaust flue gases in furnaces or boilers. A flue, also known as a smokestack or a chimney, is the vertical pipe which allows exhaust gases from combustion to be vented into the atmosphere. The exhaust gases are the result of burning fuel inside a furnace, oven, boiler or steam generator.Get Price
The most common measurement for the purposes of efficiency are oxygen (O) or carbon-dioxide (CO2) and temperature. For a given fuel type, it is possible to calculate the percent O if CO2 is measured, or to calculate CO2 if O is measured. Another common indicator is CO; if O is high, there won't be any significant CO.Get Price
The boiler combustion control and monitoring system was installed on a 25 MMBtu/hr steam boiler located at the Watervliet Arsenal in New York. A one-year test conducted between February 2011 and March 2012 demonstrated a 4% fuel savings for typical utilization with natural gas. The efficiency gain is due to a reduction in oxygen in the flue gas Get Price
Most fuels contain carbon and hydrogen while some like oil and coal also contain sulfur. When water (H20); (and sulfur dioxide, if sulfur is present).
