Kerosene and home heating oil can be mixed in a oil furnace. Kerosene is thinner than heating oil. Mixed together will make the furnace burn cleaner.
no one available to adjust can it be used fo a short time or what could happen
The kerosene is a lighter oil. I think you would get more BTUs out of the heating oil. Just make sure that you are using the right fuel for the furnace that you have. Most now days would take heating oil.
Yes and no. An unmodified oil burner will burn far more kerosene than fuel oil for which it is designed. If you replace the nozzle with a smaller nozzle and adjust the air, using an orsatz [orsat gas analyzer], a device for determining the combustion efficiency of the flame, you will be able to use kerosene. * interesting fact: Kerosene is also known as #1 fuel oil, or JP5 jet fuel. Mixing kerosene with #2 fuel oil, (home heating oil) in small amounts, should have no appreciable effect on the furnace efficiency.
Yes, in cold climates, kerosene is mixed at 10-20% with #2 FO to prevent gelling.
kerosene is a thin oil that was used in 1849 to light oil fuled lamps.
Home Depot carries a lot of things and may very well carry the oil you need for your furnace. They also carry kerosene and other fuels for heating.
Kerosene
Yes you can; According to "FlashOffRoad" "Kerosene is routinely added to home heating oil, in large quantities. The furnace doesn't know, or care. The furnace oil pump does not have the same clearances (they are more crude, greater clearances, lower pressure...) and the kerosene won't hurt them. Most will (and often do) run on straight kerosene--here in NH, if the oil tank is outside, the mix will be either 50/50 or straight kerosene. Kerosene doesn't have the same heat values either, you won't get the same amount of power from a gallon of kerosene as from heating oil, or diesel fuel." See full article for more detail <http://flashoffroad.com/Diesel/DieselFuel/about_diesel_fuel.htm> Personally though, I wouldn't add more than 10 gallons per 275 tank full just to be safe.
Whale oil early on.
Furnace oil is the source of fuel used by the heating system to create a consistent warmth when required.
Kerosene should not be used as a home heating oil unless the unit is designed to do just that, kerosene may be used in a small amount to inhibit gelling of fuel oil during extremely cold weather.
