Publication number: 20190360688Abstract: A steam flare is provided that injects steam, unmixed with air into a waste gas stream at locations where the resulting accelerated steam and waste gas mixture upon exposure to the surrounding air induces a mixture of steam, waste gas and air with improved combustion and effectively complete destruction of the waste gas, and where under low-flow conditions, reduced steam and/or assist gas are required to maintain smokeless operation. The steam is injected via multiple tubes each controlled independently so that steam can normally be flowed via a first tube, and then, when operation loads require, flowed via a second tube. The first and second tubes may be concentric and may be in communication with steam supplies that have different pressures of steam.Type: ApplicationFiled: August 8, 2019Publication date: November 28, 2019Inventors: Kurt E.

Publication number: 20130323658Abstract: A burner flame detection and monitoring system for a pilot burner for combustion of wastes gases and waste materials. The system includes a pilot burner assembly. A gas premix burner assembly includes a fuel gas delivery conduit, a fuel metering orifice, a fuel and air mixing device, a pilot tube and a pilot burner tip assembly. A primary sensor is in communication with the pilot burner assembly downstream of the fuel metering orifice. A secondary sensor is in communication with pilot burner assembly at or upstream of the fuel metering orifice. A processor receives input from both the primary sensor and the secondary sensor. A mechanism integrates the input from the primary sensor and the input from the secondary sensor in order to deduce the presence, absence or quality of a pilot flame.Type: ApplicationFiled: May 29, 2012Publication date: December 5, 2013Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Kurt E.

Patent number: 8251089Abstract: A relief system for process fluids under pressure. The system includes a normally open isolation valve in fluid communication with a process system under pressure through an upstream conduit. A buckling pin actuator is in fluid communication with the upstream conduit through a sensing line. A spring activated actuator is engaged with the isolation relief valve in order to retain the isolation valve in a closed position. A buckling actuator bypass valve is supplied with non process fluid pressure to an input port and the buckling actuator bypass valve also includes a first output port to the spring activated actuator and a second output port to a vent whereby pressure in the process system above a predetermined level will actuate the buckling pin actuator, moving said buckling actuator bypass valve to said second outlet port to vent and thereby moving the spring activated actuator in order to open the isolation valve.Type: GrantFiled: November 6, 2007Date of Patent: August 28, 2012Assignee: Honeywell International Inc.Inventors: Kurt E. Kraus, Bryan L. Beck, Dusty R. Richmond

Patent number: 7399458Abstract: A fired equipment system and process for operating same is provided that combines stationary industrial burner technology and a catalyst bed that converts pollutants formed during combustion of fuel and air in the burner to yield stack gases that need no further treatment before discharge to the atmosphere. The system and process disclosed reduces CO, NOx and VOC's by at least 90 to 95%.Type: GrantFiled: November 18, 2005Date of Patent: July 15, 2008Assignee: Callidus Technologies Inc.Inventors: Richard R.

Patent number: 6875008Abstract: An improved burner assembly and process for operating same using a burner design that produces very low levels of undesirable nitrogen oxides is provided. The burner assembly premixes primary fuel and air in a venturi system and recirculates combustion gases back to the burner through a plurality of recirculation conduits where it is mixed with the premix of fuel and air and secondary air prior to combustion in a primary combustion zone. Rapid premixing of the primary fuel and air in the venturi system and the dispersion of the recirculated furnace gases is believed to result in lower peak flame temperatures and therefore minimizing the formation of the pollutants, such as nitrogen oxides.Type: GrantFiled: January 29, 2003Date of Patent: April 5, 2005Assignee: Callidus Technologies, L.L.C.Inventors: Richard R. Martin, Doyle C. Bishop, Paul M. Rodden, Kurt E. Kraus
