Publication number: 20220133942Abstract: An apparatus and method for treating air includes a UV illumination source in a housing and arranged to expose air to UV illumination suitable to inactivate microorganisms. One or more light baffles can be arranged so that UV illumination is incident on an inlet or outlet side of the light baffle. First and second light baffles can operate as a catalyst element and each can respectively have first and second pluralities of air flow channels extending in first and second directions from an inlet side to an outlet side of the light baffle. The first and second directions can be arranged at an angle such that UV illumination is prevented transmission through the first and second light baffles. Air flow channels of a baffle can extend in a direction from an inlet side to an outlet side of the light baffle and can be inclined relative to the inlet side of the baffle by a slant angle of 10 degrees to 45 degrees.Type: ApplicationFiled: November 5, 2021Publication date: May 5, 2022Applicant: Bluezone IP Holding LLCInventors: Karen R.

Patent number: 6554608Abstract: An apparatus and method for operating a pilot burner apparatus and a main burner apparatus of a gas-fired appliance. The pilot burner apparatus draws combustion air from a first environment. The main combustion apparatus draws air from a second environment. In a shutdown condition, such as when a flammable vapor source is accidentally exposed to the second environment, the pilot burner apparatus draws air containing an undesired flammable vapor which eliminates the pilot flame, triggering a gas valve to close and shut down the fuel gas supply to the main burner apparatus and the pilot burner apparatus.Type: GrantFiled: October 3, 2000Date of Patent: April 29, 2003Assignee: Gas Research InstituteInventors: John A. Bowman, Karen R. Benedek, Stephan E. Schmidt

Patent number: 6074200Abstract: A pilot burner apparatus for use with gas-fired appliances, such as gas-fired water heaters, is provided with a structure configured for the early detection, and response to, the presence of flammable vapor in the atmosphere ambient to the appliance. Combustion air for the pilot burner is taken from that region of the ambient atmosphere, most likely to become contaminated with flammable vapor first. One or more flame characteristics of the pilot burner flame are monitored, and if the flame characteristics depart from a predetermined range of parameters, gas flow to the pilot and main burner(s) of the appliance are cut off. The sensitivity of the pilot burner is such that flammable vapors are detected before the concentration of flammable vapors car rise to the lower flammability limit of the anticipated flammable vapor(s).Type: GrantFiled: January 20, 1998Date of Patent: June 13, 2000Assignee: Gas Research InstituteInventors: John A.

Patent number: 6071115Abstract: A process and apparatus for combusting fuel which results in reduction of nitrogen oxides and carbon monoxides emissions. Fuel and primary air are preferably premixed and introduced into a combustion chamber. Secondary air is introduced through a plurality of secondary air ports, each preferably shaped as a slot, which are positioned about a venturi nozzle or flame holder disk mounted with respect to a combustion chamber wall. The secondary air flowing through the secondary air ports forms relatively high velocity and momentum secondary air jets that promote rapid mixing of the fuel and primary air mixture into the secondary air flow, such that a combustion flame is established at a partial periphery of the secondary air jets.Type: GrantFiled: September 5, 1997Date of Patent: June 6, 2000Assignee: Gas Research InstituteInventors: Philip C. Carbone, Karen R. Benedek, Stephan E. Schmidt, Charles E. Benson

Patent number: 5975883Abstract: A method and apparatus for reducing emissions in combustion products. Fuel and primary oxidant are introduced into a burner tube and discharged as a fuel/oxidant mixture, preferably fuel-rich, into a primary combustion chamber. The combustion flame entrains, through a peripheral gap between the burner tube and a wall of a first housing, a first portion of secondary oxidant in the primary combustion chamber. The combustion flame is then directed, preferably through a swaged orifice, into a secondary combustion chamber. Within the secondary combustion chamber, the combustion flame entrains a second portion of secondary oxidant and then combustion products are discharged through an exhaust tube.Type: GrantFiled: January 23, 1998Date of Patent: November 2, 1999Assignee: Gas Research InstituteInventors: Philip C.

Patent number: 5645413Abstract: A method and apparatus for low NO.sub.x combustion in natural draft combustion chambers comprising staged-air combustion apparatus and process in which a fuel-rich, fuel/air mixture is introduced through a burner into a combustion chamber, forming a fuel-rich primary combustion zone flame. The fuel-rich primary combustion zone flame is attached to a flame guide disposed substantially parallel to the longitudinal axis of the primary combustion zone flame and extending from behind the burner. The flame guide also provides for removal of heat from the primary combustion zone flame. Secondary combustion air is introduced into the combustion chamber downstream of the burner to complete combustion of the fuel-rich primary combustion zone flame products. Internal recirculation of combustion gases within the combustion chamber into the fuel-rich primary combustion zone flame stabilize the fuel-rich primary combustion zone flame and contribute to emissions reduction.Type: GrantFiled: January 20, 1995Date of Patent: July 8, 1997Assignee: Gas Research InstituteInventors: Karen R.

Patent number: 5080087Abstract: This invention is an indirect fired gas burning device having typically two gas burner assemblies, a radiant heat assembly and a convection heat assembly. The combustion products of both burner assemblies are kept separate from the convection air which is circulated through the oven. The device is adapted to be mounted within or attached to a gas stove, having an oven therein and which provides an improved gas stove which can perform the functions of: (1) bake (with controllable cooking air flow rates); (b) broil using a radiant heat assembly such as a screen broiler "looking" through or transparent to the radiant heat generated by the broiler such as an infrared window (also a new low profile screen burner assembly is disclosed); (c) steam which is possible because of the very low vent rate of the oven, i.e.Type: GrantFiled: December 6, 1989Date of Patent: January 14, 1992Assignee: Gas Research InstituteInventors: David H.
