Patent number: 9920927Abstract: A low NOx burner has a housing that includes a burner head defining a gas manifold and a primary flame zone downstream of the burner head. The burner has a gas inlet for receiving gas. Flow-through air vents are disposed around a center of the burner head and extending through the burner head thereby enabling cold core air to flow from an annular core space upstream of the burner head to the primary flame zone downstream of the burner head. The burner also includes a plurality of premix air vents in fluid communication with the manifold for premixing air and gas within the manifold and for emitting premixed air and gas into the primary flame zone. A plurality of staging pipes extend from the manifold into the primary flame zone for conveying gas into the primary flame zone. The burner includes an ignition device extending into the primary flame zone.Type: GrantFiled: August 13, 2013Date of Patent: March 20, 2018Assignee: Haul-All Equipment Ltd.Inventors: Sergiu Desi-Seulean, Jerry Ejdrygiewicz, David Neufeldt

Patent number: 9115911Abstract: A direct-fired heater suitable for connection to duct work is provided. The heater comprises a combustion chamber defined by a combustion chamber wall, a burner plate at one end proximate a fan blade and an exhaust plate at an opposite end, the burner plate having openings therein for allowing airflow into the combustion chamber and the exhaust plate have an opening therein for allowing exit of heated exhaust from the combustion chamber, the combustion chamber wall extending past the burner plate. A first airflow zone exists between the outer shell and the combustion chamber allowing airflow between the fan blade and the outlet in the outer shell. An injector for injecting gas into the combustion chamber in proximity to the openings in the burner plate is used. The heater also comprises a nose cone between the outlet in the outer shell and the exhaust plate.Type: GrantFiled: July 31, 2008Date of Patent: August 25, 2015Assignee: Haul-All Equipment Ltd.Inventors: Sergiu Desi-Seulean, David Wiebe-Neufeldt, Jerry Ejdrygiewicz

Publication number: 20100024794Abstract: A direct-fired heater suitable for connection to duct work is disclosed. The heater comprises an outer shell comprising an inlet for allowing inlet of air to be heated and an outlet for exhausting heated air. A fan blade is operatively connected to a fan motor for operating the fan blade. The heater also comprises a combustion chamber defined by a combustion chamber wall, a burner plate at one end proximate the fan blade and an exhaust plate at an opposite end, the burner plate having openings therein for allowing airflow into the combustion chamber and the exhaust plate have an opening therein for allowing exit of heated exhaust from the combustion chamber, the combustion chamber wall extending past the burner plate. A first airflow zone exists between the outer shell and the combustion chamber allowing airflow between the fan blade and the outlet in the outer shell. An injector for injecting gas into the combustion chamber in proximity to the openings in the burner plate is used.Type: ApplicationFiled: July 31, 2008Publication date: February 4, 2010Applicant: Haul-All Equipment Ltd.Inventors: Sergiu Desi-Seulean, David Wiebe-Neufeldt, Jerry Ejdrygiewicz
