Abstract: A glycerin burning system having a specialized atomizing burner capable of combusting a continuous feed of crude or pure glycerin. The burner preferably includes an impingement nozzle. The nozzle has an internal distributor which mixes two fluid feed streams (glycerin and air) and expels the fluid through an orifice. The distributor has channels which cause the air to swirl before mixing with the glycerin. An impingement pin is provided outside the orifice. The rapidly ejected glycerin/air mixture strikes a target surface on the impingement pin which transforms the mixture into a fine mist having a reduced velocity. The nozzle is located on the central axis of a turbulator which surrounds the atomized spray with rapidly revolving air. An outlet choke is provided on the combustion chamber to limit the speed of the flow so that steady combustion is maintained.

Abstract: A glycerin burning system having a specialized atomizing burner capable of combusting a continuous feed of crude or pure glycerin. The burner includes a two-fluid mixing nozzle. The nozzle has an internal distributor which mixes two fluid feed streams as the fluids are expelled through an orifice. The distributor has channels which cause the air to swirl before mixing with the glycerin. An impingement pin is provided outside the orifice to diffuse the mixture and reduce combustion air speed. To improve performance, the burner's air feed line is subjected to combustion chamber to preheat the air passing through the feed line before the air is mixed with the glycerin.

Abstract: A waste oil burning system having a burner and a heat exchanger for preheating atomizing air before the atomizing air is supplied to the nozzle. The burner includes a fuel conduit for supplying waste oil to the burner and an air supply line for supplying atomizing air to the burner. The burner has a nozzle which atomizes the waste oil by mixing the waste oil with the air from the air supply line. The nozzle sprays the atomized waste oil into a combustion zone where the atomized waste oil is combusted. The heat exchanger is positioned in the combustion zone, so that energy produced from the combustion of the waste oil preheats the air supplied through the air supply line before the air is mixed with the waste oil.

Abstract: Disclosed is an oil burning system that is capable of burning oils of varying viscosities, including high viscosity waste oils and low viscosity heating oils. Suitable as a new installation or a retrofit modification, the present invention incorporates the use of a variable rate, high-pressure oil delivery system, along with an oil pre-heater, in conjunction with a modified high-pressure atomizing nozzle. Installed in a sliding drawer burner arrangement that allows for quick and easy access, the oil burning system also includes a means by which particulate matter and carbonization build-ups are removed from the burner nozzle automatically, thereby eliminating the need for frequent cleaning.
