Can you mix kerosene and cooking oil from fryer to burn in home furnace?

Here's why:

* Fire Hazard: Kerosene is highly flammable and can ignite easily. Mixing it with cooking oil creates a volatile and unpredictable fuel source. The mixture could easily ignite and cause a fire.

* Furnace Damage: Your furnace is designed to burn specific fuels. Mixing kerosene and cooking oil could clog the burner, damage the heat exchanger, and potentially cause a catastrophic failure.

* Health Risks: The burning of cooking oil can release harmful fumes and particulate matter into the air, posing a serious health risk to you and your family.

Alternatives:

* Burn Kerosene Safely: If you have a kerosene-burning furnace, only burn pure kerosene. Ensure you have a proper storage container and follow all safety precautions.

* Recycle Cooking Oil: Do not dispose of cooking oil down the drain. Contact your local waste management facility for proper disposal or recycling options.

* Use Biomass Fuels: Consider using approved biomass fuels like wood pellets or corn for your furnace if it's compatible.

Always consult your furnace manual and follow the manufacturer's recommendations for fuel types. If you have any doubts about fuel use, contact a qualified heating professional.
