Aug 01, 2011 · A common source of CO 2 is liquefied carbon dioxide from a pressurized tank, and is a safe option to ensure quality gas injection. The reservoir capacity can range from 20 kg to 52,000 kg of CO 2. Pure CO 2 facilitates the control of desired concentrations, but remains the most expensive source.

Most industrial and commercial users of packaged boilers now fire natural gas. You'll find #2 oil commonly used as a back-up fuel for hospitals and industry, and in some geographic areas without natural gas service. This information is intended for use by the vast majority that fire natural gas and also touches on #2 oil.

boilers, nearly all of the fuel carbon (99.9 percent) in natural gas is converted to CO2 during the combustion process. This conversion is relatively independent of boiler or combustor type.
5 - 10% for natural gas; 5 - 20% for fuel oil; 15 - 60% for coal; Carbon dioxide - CO 2 - is a combustion product and the content of CO 2 in a flue gas is an important indication of the combustion efficiency. Optimal content of carbon dioxide CO 2 after combustion is approximately 10% for natural gas and approximately 13% for lighter oils.
Excess Air. A boiler's excess air supply provides for safe operation above stoichiometric conditions. A typical burner is usually set up with 10-20% excess air (2-4% O2). NOx controls that require higher excess air levels can result in fuel being used to heat the air rather than transferring it to usable energy.
