A boiler takes fuel oil of specific gravity 0.81 and calorific value of 27912KJ/KG form a tank 6.0M in diameter. At the time of the maximum firing, the level of fuel oil in the tank is lowered 51mm in one hour, and the absolute boiler pressure is 1620Kpa.
What is the mass flow rate of steam from the boiler in KG/HR
Note: I can get to the point of finding the calories released per hour of the fuel, but I'm having some trouble translating that into an evaporation rate for the boiler. Any thoughts?
