How to Run a Coal Fired Boiler at the Best Efficiency .

Boiler efficiency is mainly depended on the amount of losses in the system. In high capacity pulverized coal fired boilers the total losses account to about 12 to 14%. Roughly 50% of the losses are governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The other 50% losses are carbon loss and dry gas loss.

boiler efficiency guide - cleaver-broo


key factor is fuel usage or boiler efficiency. Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units ...

The current standards for residential hot water boilers require a minimum efficiency of 82% for gas-fired equipment and 84% for oil-fired equipment. In 2016, DOE finalized new standards for residential boilers that will raise the minimum efficiency levels to 84% and 86% for gas-fired and oil-fired hot water boilers, respectively. The new standards will take effect in 2021.

The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.

Boiler Combustion | CleanBoiler.o

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.
