Latest Patents

Troth’s listed patent, “Heavy Fuel Combustor,” describes an apparatus intended to vaporize and burn heavy residual fuel while controlling combustion and emissions. Its design uses an elongated vaporizing tube, an air-blast nozzle, and a preheater arrangement that swirls the fuel and air to promote vaporization while preventing autoignition.

The patent also describes a primary crossed-slot air mixer that cools the air-fuel mixture and establishes a lean mixture for combustion. A torch igniter directs a flame into the mixture to support continuous combustion under varying gas-turbine operating conditions. The stated objective is to reduce hydrocarbon and carbon monoxide emissions.

Career Highlights

Troth’s documented patent contribution focuses on gas-turbine combustor design, particularly the challenges of vaporizing and burning heavy residual fuel. The patent combines fuel preparation, air mixing, and flame ignition in a system intended to maintain controlled combustion.

Collaborations
