I was looking at Gas powered Electricity Generators today, and needed to work out the LPG consumption from the quoted mj/hr figures being quoted in the product specifications.
The figures quoted, for both LPG and Natural Gas were:
I did find that 1kg of LPG was equivalent to about 50MJ of LPG energy.
So a standard 8.5kg LPG gas bottle would last for about 5 hrs 45 minutes at full power producing 4.4KW of constant power.
So… about 25 kilowatt hours for $20 LPG cost, or almost 80 cents per hour per kW, using that particular generator.
