Boiler
**************************************************************************
NOTE: The specified efficiency for the boiler at
maximum continuous load shall be not less than 80
percent for coal and 82 percent for oil. When an
economizer is provided, use 82 and 84 percent
respectively for coal and oil firing. Depending on
the particular application and fuel used, these
efficiencies could be higher.
**************************************************************************
The efficiency listed for coal burning shall be based on stoker firing with
[_____] percent excess air. [The efficiency for fuel oil firing shall be
based on [_____] percent excess air]. The efficiency shall allow for
[_____] percent continuous blowdown and 1.5 percent unaccounted losses and
manufacturer's margin. Base the performance on the boiler burning fuels in
accordance with the Coal Analysis [Fuel Oil Analysis] listed below.
