I tried looking this up and was surprised at the plethora of irrelevant info (such as combustion heat) that turned up, and the dearth of info on the specific heat of the fluid.

My wild guess: oil ≈ 0.8 (??). I'll keep trying.

The flash temperature of #2 heating oil is min-max.. 52 - 87 dg C. Flash temperature means self-igniting. So it looks like heating it to 95 C is not a practical idea.

Just a pont of order, if aI may. Flash point doesn´t equate to self-ignition. Strictly speaking FP is the temperature at which the liquid would ignite if and open flame were swept over the liquid surface on a open vessel.

Heat transmission by McAdams reports a value 0.56 KCal/(Kg.DegC).

0.56 x 1200 x 0.87 x 55 KCal/Hr.

From Tim Hawley Master Mech.

Hello Guest,

Your question is; How much energy is required to increase the temperature from

40 Deg. C or (104 Deg. F) TO 90 Deg. C or (194 Deg. F).

Energy is measured by (BTU) British Thermo Units. In order to measure BTU's you will have to provide the size of the heating area of the capsule you wish to increase the temperature by 90 Deg, F.

Please provide additional information , only then can an answer be provided.

NOTE: A race car high performance fuel pump output in Liters Per Hour is only 200 to 255 LPH. You must be powering a very large ship!

Best Regards,

Tim

Can't agree with that. He asked for energy to heat the oil. As he gave a flow he should have said power, not energy, but that's a common mistake and it's fairly clear what he meant. Details of the equipment don't come into it.

And he referred to furnace oil, so it's likely to be a furnace or boiler he's feeding, not an engine. If it's a steam boiler I make it about 18 tonne/h steam output, which is biggish, but not huge.

Cheers........Codey

Hello Codemaster,

Fuel oil stoves have a carburator that regulates flow. The fuel oil flows in the a heat chamber. I want to know how large the heat chamber is. This is what I ment by "capsule".

Regards, Tim

1200 LPH is a lot of fuel. I measure 317 US gallons per hour, @ $2.80 USDollars per gallon equals 888.00 per hour to operate this beast.

My conclusion is this isn't a house hold heating stove. Give me the size of the heat chamber and I will calculate (energy required to increase 100 Deg. F).

Best Regards, Tim

How did the phone call to the supplier of the <...furnace oil...> go?

Where is the Materials Safety Data Sheet for the <...furnace oil...>?
