A heating system includes a furnace configured to receive a product to be thermally treated within the furnace, where the furnace includes at least one burner to generate combustion gases from a source of oxygen and a carbon-based fuel source provided to the burner, and the combustion gases provide heat to the product disposed within the furnace. A gas pipeline delivers a heated inert gas into the furnace at a location proximate the product so as to at least partially surround and protect a surface of the product and minimize or prevent the product from chemically reacting with other gases within the furnace.
