A 150,000 kg of coal supplied to two boilers. One has a capacity of 350 kg/hr and the other boiler has a capacity of 100 kg/hr. Air fuel ratio of boilers are 15 and 10 respectively with an ash loss of 11% to both. The pressure and temperature of the gas as it directs to chimney is 98kpa and 130°C. Use molecular weight of gas of 30kg/kgmol. Determine the diameter of the chimney of the most consumed fuel if the draft pressure is 2.79cm H2O.

Question

A 150,000 kg of coal
supplied to two boilers. One has a
capacity of 350 kg/hr and the other
boiler has a capacity of 100 kg/hr.
Air fuel ratio of boilers are 15 and
10 respectively with an ash loss of
11% to both. The pressure and
temperature of the gas as it directs
to chimney is 98kpa and 130°C.
Use molecular weight of gas of
30kg/kgmol. Determine the
diameter of the chimney of the
most consumed fuel if the draft
pressure is 2.79cm H2O.
