A torch canister with a fuel reservoir has a neck extending from the top of the fuel reservoir defining a wick holder. The torch canister has a flame guard affixed to the neck.

A combustion system using at least 90 wt % propylene glycol based liquid fuel includes a first fuel tank, a wick inserted in the first tank, a sensing unit configured to receive an activating signal and sense the liquid level of the propylene glycol based liquid fuel in the first fuel tank and send a fuel replenishment signal accordingly, a second fuel tank, a conduit system connected with the first and the second fuel tanks, and a drive unit connected with the conduit system and configured to receive the fuel replenishment signal so as to cause the propylene glycol based liquid fuel in the second fuel tank to replenish the first fuel tank through the conduit system as well as to cool the wick.

A submerged combustion burner, a submerged combustion melter including the submerged combustion burner, and method of operating the submerged combustion burner are disclosed. The submerged combustion burner includes central burner tube and a heat pipe that surrounds and extends beyond a terminal end of the central burner tube. When received in a burner opening defined in a melting tank of a submerged combustion melter, the heat pipe of the submerged combustion burner is disposed between the central burner tube and the floor of the melting tank. The heat pipe transfers or pumps heat via a sealed working fluid to a cooling fluid that thermally communicates with the heat pipe exterior to the melting tank.

An example Smart Candle Platform is configured to includes a candle fixture that comprises an outer shell having an opening, a mid-frame, and a base, and a fuel bottle configured to hold a fuel material and is removably coupled to the candle fixture. The fuel bottle is positioned at least partially within a hollow interior of the mid-frame of the candle fixture and accommodated by the base. The fuel bottle further comprises a wick that extends through an opening of the outer shell, and the candle fixture includes an ignitor configured to ignite the fuel material via the wick to produce a living flame. The candle fixture further includes an inner cover having one or more reinforcement ribs configured to provide structural support for the one or more ignitors.

A refillable torch canister includes a container having top which includes a fill opening and a cover including a fill opening which can be axially aligned with the fill opening of the top to permit insertion of fuel therethrough, and which can be moved so the fill openings are out of alignment precluding fluid to pass therethrough. Also, included is a pre-filled fuel container having spout with a complementary configuration to be received within the fill openings.
