A steam boiler produces English ton of steam from am to pm
continuous operation per day. The steam enters the turbine at bar and
degrees Celsius. The pump feeds the boiler with water that has a temperature of
degrees Celsius. If the burner in the boiler uses bunker diesel fuel with
degrees API, calculate the volume of diesel that must be burned in gallonsminute
if the efficiency of the boiler is The temperature of the Diesel is supplied to
the boiler at degrees Celsius.
Four boilers operating steadily on metric tons of highgrade bituminous
coal contained in a bunker. Boiler produces metric tonshr of steam at
mpa and degrees Celsius and feedwater temperature of degrees Celsius
with an efficiency of Boiler produces of the Boiler steaming
capacity at saturated steam at mpa and the feedwater temperature of
degrees Celsius with efficiency. The third boiler produces steaming
capacity of Boiler at degrees Celsius saturated with efficiency. Boiler
produces of Boiler steaming capacity with factor of evaporation of and
boiler efficiency of Compute the number of days the coal in the bunker
runs the four boilers if the coal has a heating value of KJkg Assume
bour operation per day.
The following coal has the following ultimate dry analysis by weight.
and Ash The steaming capacity of
the boiler using this coal is short ton covering a period of am to pm
Calculate the volume of air needed in at kpa and with a excess
air of The boiler efficiency is The stream leaves the boiler at bar and
degrees Celsius while the feedwater enters the boiler at degrees Celsius.
