Abstract:
Example embodiments relate to a burner unit for combusting an air-fuel mixture. The burner unit includes an air supply dome having recesses which have a larger width on an inside of the air supply dome than on an outside.
Abstract:
A fresh-air intake according to aspects of the disclosure includes an outer cover having a pair of side panels disposed in a generally parallel spaced relationship, a top panel coupled to, and disposed generally perpendicular to, each panel of the pair of side panels, a bottom panel disposed generally parallel to the top panel, and a front panel coupled to, and disposed generally perpendicular to, each panel of the pair of side panels and the top panel, the front panel having a window formed therein, a supply line coupled to the bottom panel, a weir extending above the bottom panel and surrounding a junction with the supply line, a baffle disposed inside the outer cover, the baffle being disposed inwardly of the window so as to prevent infiltration of moisture into the supply line, and a weep hole formed in the bottom panel.
Abstract:
The disclosed technology includes a device for extending the turndown ratio of a gas-fired burner system. The device can comprise a variable area device configured reduce the amount of fuel and air passed to the burner during low output conditions by adjusting the cross-sectional area of the passage between the blower and the burner. The variable area device can be controlled by an actuator that adjusts the position of the variable area device. The actuator can be manually controlled, mechanically controlled, or electronically controlled.
Abstract:
Heat and power engineering, specifically being heating devices includes a pyrolysis boiler, in which, wood is subjected to high-temperature gasification and pyrolysis with subsequent burning off of pyrolysis gases. A stable and controllable gasification of wood with a natural high moisture content is achieved, and at the same time, a highly efficient transfer of combustion heat to a liquid heat-transfer agent is obtained. A gasification chamber is positioned between two compartments of a pyrolysis gas combustion chamber of the pyrolysis boiler, while the external wall of the combustion chamber is used as a heat-transfer surface, and at the same time, neither the fuel bunker nor the gasification chamber are in contact with water.
Abstract:
An HVAC burner box includes a burner bank, a manifold and an air director located within an enclosure. The burner bank is oriented such that an outlet end of the burner bank is directed toward a first end of the enclosure. The manifold is located within the enclosure and adjacent an inlet end of the burner bank. The air director has a diffuser that is coupled to a side of the enclosure. The diffuser includes a plurality of openings located therethrough. The diffuser is configured to direct a first portion of a received airstream through the opening and toward the burner bank. The diffuser is further configured to send a second portion of the received airstream toward the manifold.
Abstract:
A combustion apparatus having a burner, a combustion box, a combustion fan for supplying combustion air, and a regulator for regulating the amount of combustion fan, an inspection operation is performed in a state in which an operational quantity of the regulator (fan rotational speed) is kept at a maximum amount Nmax. When a deviation between a maximum set combustion amount YQmax corresponding to supply/exhaust resistances as detected in the inspection operation and an actually measured maximum combustion amount Qmax is outside an allowable range, a secondary inspection operation is performed by lowering the fan rotational speed down to a value Now which is lower than Nmax by a predetermined rate. Based on the rate of decrease of Qlow relative to Qmax as detected by the secondary inspection operation, computation is made of a fan rotational speed Nsat at which the burner combustion amount ceases to increase even if the fan rotational speed is increased. The upper limit value of fan rotational speed is then changed to Nsat.

Abstract:
A well test burner system includes a plurality of burner nozzles. At least one of the burner nozzles includes a well product inlet, an air inlet, an air/well product mixture outlet, and an automatic valve. The automatic valve is responsive to a remote signal to cease flow of well product to the air/well product outlet.
Abstract:
An area-specific centrifugal combustion apparatus is provided using a flow of combustion air. Combustion air is supplied through an upper combustion chamber. A column of fire is discharged from the upper combustion chamber. A lower combustion chamber is coupled with a lower part of the upper combustion chamber, and supplies fuel into a combustion chamber for mixing with the combustion air for combustion. An air supply pipe has an upper supply pipe and a lower supply pipe, through which the combustion air is supplied to the upper and lower combustion chambers. A rotary part connected to the lower combustion chamber allows the combustion air to maintain centrifugal force. A fuel supply on a lower end of the rotary part includes a fixed quantity feeder allowing a fixed amount of fuel to be supplied.
Abstract:
A gas burner unit for a cooktop having a spreader positioned above the top surface of the cooktop. The spreader has a plurality of gas outlets. A venturi is in fluid communication with the gas outlets. An orifice holder secures a gas orifice in position in a main body of the orifice holder and has a plurality of protrusions extending upwardly and defining a plurality of upwardly directed primary air inlets. The plurality of primary air inlets are in fluid communication with the main body of the orifice holder, and the main body is in fluid communication with the venturi. A general primary air inlet allows ambient air from outside the cooktop to enter the area below the cooktop, and the main body of the orifice holder includes openings allowing fluid communication between the area below the cooktop and the main body of the orifice holder.
