| 7299768 | Gas-fired water heating apparatus The water heating apparatus has an upright cylindrical thermally insulated storage tank, an axially extending exhaust gas pipe passing centrally through the storage tank and a combustion chamber under the storage tank. An atmospheric gas burner, which has a complete... | 11/27/2007 |
| 6675795 | Freeze resistant method for draining furnace condensate in low temperature environments A freeze resistant method for draining liquid condensate from a condensate furnace includes quickly purging the liquid condensate from a condensate reservoir. A condensing heat exchanger connected to a condensing reservoir stores liquid condensate as the ... | 01/13/2004 |
| 6276926 | Injector for water free of external torch An injector for water free of external torch external torch gas injector comprising an outer tube, a first inner tube and a second inner tube. The outer tube has a side tube and a plurality of outer tube emission holes. The outer wall of the outer tube jo... | 08/21/2001 |
| 5498153 | Gas flare A gas flare is described which includes a vent stack for combustion air having a first end and a second end. A gaseous fuel cyclone chamber surrounds the vent stack. The cyclone chamber has an interior wall conterminous with the vent stack and an exterior... | 03/12/1996 |
| 5474442 | Vaporizing diesel burner Diesel fuel is vaporized and then burned on a cylindrical screen flame holder. The fuel is vaporized in a finned, vertical tube vapor generator and directed through a superheater tube past the flame to a flow control valve and nozzle. A flow restriction i... | 12/12/1995 |
| 5456595 | Device for preventing flareup in barometric-type wick-fed liquid fuel burners A safety device for preventing uncontrolled burning in wick-fed liquid fuel burners employs an excess fuel containment compartment (24) which receives any excess fuel which might be fed to the fuel supply chamber (40). The excess fuel causes a receptacle ... | 10/10/1995 |
| 5409370 | Liquid fuel burner safety device employing fuel tank shutoff A safety device for preventing uncontrolled burning in wick-fed liquid fuel burners employs an excess fuel containment compartment (24) which receives any excess fuel which might be fed from a removable tank (60) through a spring-loaded valve in the remov... | 04/25/1995 |
| 5282738 | Liquid fuel feeding method and liquid fuel burning apparatus The liquid fuel burning apparatus includes a fuel tank, a burning unit for burning the fuel, an electromagnetic pump for sucking the fuel from the tank, a feeding pipe for feeding the sucked fuel to the burning unit, and a control unit for controlling the... | 02/01/1994 |
| 5085576 | Apparatus and method for detecting leaks in a system for delivering gaseous fuel A leak detector for a valve controlling flow of fuel to a combustion chamber employs a fuel concentration sensor in a sensing chamber placed downstream from the valve seat. The valve has a downstream chamber which is in communication by diffusion through ... | 02/04/1992 |
| 4773848 | Sealed gas control valve A gas burning furnace is disclosed with a sealed and vented gas control valve. Sealing the gas control valve in an enclosure shields the control valve from the external environment. By venting the enclosure to the furnace pilot light, any gas leaking from... | 09/27/1988 |
| 4664619 | Burner nozzle A burn nozzle for mixing petroleum products to be burned and air in which air is injected into the petroleum stream leaving a nozzle from an air can which is spaced from the nozzle and its petroleum product supply line such that any leakage from the oil s... | 05/12/1987 |
| 4372290 | Gas burner head with means for evacuating trapped water condensate A generally concave-shaped gas burner head is provided with circumferentially spaced means on the periphery of top and bottom portions for enabling water accumulated therein due to condensation of water vapor to flow out of the burner head without interfe... | 02/08/1983 |
| 4205972 | Gas valve with integral drip leg and filter A gas valve device includes an integral drip leg and filter, positioned upstream from valve means contained therein, for collecting and removing liquid and solid impurities from a gas stream. The drip leg and filter includes a fine-mesh screen of signific... | 06/03/1980 |
| 4149842 | Waste oil burner A burner for hydrocarbon fuel, such as waste lubricating oil for internal combustion engines and the like, has a fuel line terminating in a discharge nozzle and connected to a source of the fuel.
