  • Patent number: 8209971
    Abstract: The present disclosure provides a burner for increasing the temperature of a gas stream, such as an exhaust gas stream, to burn particulate matter and unburnt hydrocarbons within the exhaust gas. As well, by heating or increasing the temperature of the gas stream and combustion products exiting the burner, the gas stream is brought into a condition more suitable for additional treatment to further reduce exhaust gas emissions from the engine. The device includes an outer housing and a series of combustion chambers mounted within the outer housing for increasing and further developing combustion of the incoming gases within the series of combustion chambers. A primary application for the device is for use with diesel engines to burn particulate matter and unburnt hydrocarbons within the diesel emissions and/or act as a heat source for activating diesel particulate filters and/or other catalytic components or devices.

The burner cap rests upon the burner head and contains an outer edge that is turned downwards in order to allow fluid to drip away from the flame. A groove is cut into the burner cap just inside the down turned outer edge and provides a location for a support flame. The location of the groove prevents fluid and dust from collecting inside the groove. The groove captures the flammable gas-air mixture, which provides a constant ignition source for the gas-air mixture through slots in the burner cap when ignited.

    Abstract: A hot water heater capable of delivering a relatively large quantity of hot water, the quantity being larger than the total volume of the storage capacity of the heater is disclosed.The hot water heater comprises a vessel having an inlet port and an outlet port, a cold water inlet coupled to the inlet port, a hot water outlet line coupled to the outlet port, with heating means for heating water in the vessel, and control means for establishing a flow path between the inlet and outlet lines. The arrangement is such that water flowing in the inlet line is divided between the flow path and inlet port in a predetermined ratio whereby water flowing in the outlet line is, in use, colder than the water passing through the outlet port.

  • Patent number: 5441405
    Abstract: A gas burner system in which a turbulator disk is arranged between a burner and an opening in a combustion chamber aligned with the burner. The turbulator disk defines a central port and a plurality of peripheral voids adjacent to the central port. A burner flame, produced by ignition of a gas-primary air mixture, together with a quantity of secondary air, may be directed through the central port of the turbulator disk into the combustion chamber. A additional quantity of secondary air may be directed through the voids into the combustion chamber for combustion of the uncombusted gas from the gas-primary air mixture.

  • Patent number: 5406703
    Abstract: A cooking-type elongate bar burner having a plurality of gas flow apertures and a top surface is defined in part by a stiffening ridge and by a pair of laterally extending flanges. The apertures are beneath the flanges and thereby substantially protected from grease clogging. The burner is roll formed of a single piece of sheet material and is configured to directly accept a gas flow control valve. Also a unique "intra-burner" cross-over ignition arrangement and a method for making the new burner by roll forming are described.

  • Patent number: 5379750
    Abstract: A burner assembly for a gas furnace includes an elongated support member and a number of individual burners. The support member includes consecutive yoke sections for receiving a corresponding burner and shelves for supporting a flange segment formed around the periphery of each burner. Each flange segment of the burners includes a pair of mounting apertures which receive bendable tabs provided on the support member when the burner is positioned within a corresponding yoke section and supported by consecutive shelves. When the tabs are bent over, the individual burners are secured to the support member. The support member also includes mounting ears for quickly mounting and removing the burner assembly to a bracket provided in the burner box of the gas furnace.
