Conversion of Existing Coal-Fired Boilers to Natural Gas
improves boiler cleanliness and tends to increase heat absorption. However, combustion -zone radiation rates to the furnace walls tend to be lower. Achieving design steam temperatures and full boiler output can be difficult for a boiler originally designed to burn coal. Higher tube -metal temperatures may be experienced when firing natural gas.

How they piped coal-fired steam systems - Heating Help
Nov 21, 2014 · "Well, since it was piped for coal, it's probably going to give you a problem when you change the boiler. Remember, the new steam boilers we use nowadays don't contain nearly as much water as the old ones we take out. They go off on low water a lot quicker." "Tell me about it!" he laughed.

Installation and Operating Manual for the - EFM Heating
– Flue gas from the outlet of the boiler is mixed with the combustion air to the burners. – FGR reduces the combustion temperature and lowers the localized O2 concentration in the primary combustion zone to achieve a reduction in NOx. – Increasing the flue gas flow through the convective pass of the boiler increases heat transfer.
