Derating Gas Burners. Derating, or down-firing, is the practice of installing a lower gallon per hour (GPH) rated nozzle in a gas-fired appliance to reduce fuel use in the event that your boiler or furnace is oversized. Doing so properly often requires reconfiguring the shape/size of the combustion chamber and/or adjusting the fuel pump pressure.Learn More
Coal fired boilers normally operate with 3-3.5% O2 (about 20% excess air). Whereas natural gas boilers normally operate at 1-1.5% O2 (about 7% excess air).? Steam and exit gas temperatures. Upon switching from coal to natural gas, heat transfer characteristics of a boiler will be impacted. The characteristics of these impacts are highly dependent on unit design and configuration and are unit specific. Coal contains ash whereas natural gas …Learn More
