Minimum efficiency reporting value - Wikipedia

Minimum Efficiency Reporting Value, commonly known as MERV, is a measurement scale designed in 1987 by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) to report the effectiveness of air filters in more detail than other ratings. For example, a HEPA filter is often impractical in central HVAC systems due to the large pressure drop the dense filter material

Central Heating Fault Finding and Fault Repair for DIY

Boiler: Check the pilot light: In older boilers there will be a visible pilot light which will only be alight if there is a supply of gas and electricity. More modern boilers tend to have a pilot flame that is only visible when the boiler fires up, or is not visible at all. Check that there is a gas and electricity supply.

Flue Gas Recirculation (FGR) - CCA Combustion Systems

Flue Gas Recirculation (FGR) is a powerful nitrogen oxide (NOx) control technique that significantly reduces NOx emissions by recirculating flue gases from the boiler exhaust duct into the main combustion chamber. This process reduces peak flame temperature and lowers the percentage of oxygen in the combustion air/flue gas mixture, thereby

Complete Combustion - an overview | ScienceDirect Topics

Complete combustion of hydrocarbons (without impurities) in the presence of enough oxygen produces water vapor and carbon dioxide. Separation of water vapor from the gas stream is simple; condensation can provide the suitable separation. In precombustion technologies, combustion is made using pure oxygen (up to 97% purity); however, a small amount of nitrogen and argon remains.
