摘要： A high momentum industrial gas burner designed to create a high velocity which, in turn, is capable of creating high wind circulation that can be maintained during burner turndown. The various chambers of the burner are specially designed, so that fluid pressure within the burner is less than atmospheric pressure, or the fluid pressure within the heating chamber of a furnace wherein the burner is used to heat, for example, air.

摘要： A burner within which there is a jet pump means. High pressure primary combustion air is fed to an inlet in the burner housing and then through the jet pump means. The high pressure air flowing through the jet pump means draws a secondary low pressure, high temperature air into the burner. The jet pump means entrains the secondary air within the primary air to form a combustion air mixture. A fuel means feeds fuel to the burner housing and the combustion air and fuel combine to form a suitable mixture for ignition. A swirler can be located within the means to feed the primary air to the inlet or within the burner itself. By swirling the primary air the flame pattern of the burner can be controlled. The burner of the present invention is particularly adaptable for soaking pits having a tile recuperator and the metallic recuperator disposed within a flue gas passageway.

摘要： There is provided an efficient, economical apparatus for cooling hot gases which includes three generally cylindrical, tubular members arranged in an upstanding U-shaped configuration. The hot gases are introduced downwardly into the first leg or member of the configuration where a plurality of water nozzles provide a water boundary circumscribing the interior of the first leg to prevent thermal fatigue thereof. A water nozzle in the first member acting as a jet pump entrains the hot gases and directs them into the transverse leg or member of the configuration for rapid,turbulent cooling therein. Packed beds are provided in the second upstanding leg or member of the configuration to permit scrubbing of the cooled gases prior to exit. Coolng the gases in such a manner permits the entire configuration to be constructed of steel plate without any special insulation.

摘要： An industrial gas burner is disclosed which operates at low air/fuel ratios to avoid NO.sub.x formation without carbon sooting. The burner includes a refractory block having a cylindrically stepped throat passage extending therethrough, a housing adjacent the inlet end of the refractory block and a swirl plate inbetween the block and housing. Vane passages in the swirl plate provide fluid communication between the throat passage and an annular entrainment passage in the housing. A plurality of circumferentially spaced gas jet nozzles in the entrainment passage cause jet entrainment and mixing of fuel and combustion air which is ported to the entrainment chamber. The jet streams of mixed air/fuel impinge the swirl plate whereat the mixture undergoes a further mixing because of the pressure drop and swirling therein. The swirling air/fuel mixture is thus intimately and thoroughly mixed when it exits the swirl plate as a swirling mass at the entry end of the throat passage where it is ignited. The mixing is so intimate that combustion of the air/fuel can occur at ratios as low as 5 to 1 without carbon sooting and NO.sub.x formation.

摘要： A radiant burndown tube for furnaces which have a chamber sealable from the ambient atmosphere and in which there is a combustible gas. The burndown tube is divided into three functional areas; the burner leg, the exhaust leg and a tube portion. The tube portion is located within the furnace chamber. There is an inlet where the combustible gas from the furnace chamber is drawn into the burndown tube. The combustible gas is mixed with air and ignited in the tube and the combustion products are exhausted via the exhaust leg. Thus, the heat energy normally lost in the burndown of combustible furnace exhaust gases outside of the furnace is captured and used to provide additional heat to the furnace.

摘要： A heat exchanger includes a long, thin-shelled heat transfer tube closed at one end and secured at the other end to a manifold collar which has an exhaust tube extending from the center thereof and a manifold housing extending from the collar side opposite that from which the heat transfer tube extends. A plurality of longitudinally extending distributor tubes extend from the heat transfer tube through the collar in fluid communication with a sealed manifold chamber and a plurality of orifices spaced at longitudinal increments along the length of each distributor tube permits the wind mass in the manifold chamber to exit the orifices as high speed, free-standing gas jets for impingement against the interior of the heat transfer tube so that the heat transfer tube acts either as a heat source or as a heat sink. An annular manifold plate spaced slightly from the collar defines a cooling space between the manifold plate and collar and orifices within the manifold plate permit a small portion of the wind mass to enter into the cooling space for heat transfer cooling of the collar while the collar also shields the manifold plate from heat within the heat transfer tube. A bleed path between exhaust tube and collar allows the gas in the cooling space to flow through the exhaust tube to maintain the manifold collar at an even temperature gradient.

摘要： An in situ thermal system is disclosed for enhanced oil recovery and the like from a subterranean formation. The system pressurizes the formation with water whereupon the entire formation is heated to relatively high temperatures in the absence of gas formation to significantly decrease the viscosity of substantially all the crude in the formation and permit recovery thereof. A down hole, fuel fired radiant tube burner of long length is provided to achieve the desired heat patterns within the formation. The burner includes three concentric, closed end tubes with the innermost tube containing a burner and spaced closely adjacent the intermediate tube. A hole pattern in the innermost and intermediate tube establishes a laminar flow of the burner's products of combustion therebetween which modifies the radiation heat flux pattern so that uniform heat is emitted from the outermost tube along its length.

摘要： A fuel fired heat treating furnace having an imperforate inner shell for containing a work load in isolation. The shell is made of a refractory material which provides a good heat exchange from the outside to the inside. A multiplicity of hot gas streams is directed under pressure against the outside of the shell by means of a circulation system which includes a plenum, a fan within the plenum and a plurality of apertured distributor tubes extending from one end of the shell to the other. Fuel burners exhaust combustion gases into the system on the discharge side of the fan where the gases mix with returning gases from the intake side of the fan and are fed into the distributor tubes.

摘要： An improved heat transfer arrangement for use in a unique multi-function, industrial heat treat furnace which employs a sealed, closed end, heat exchanger shell member containing the work. The heat transfer arrangement includes a totally contained, internal recirculation system which develops an especially configured annular jet stream that produces highly efficient, convective heat transfer with the shell member. After heat transfer between the entrained gases in the jet stream with the shell member has occurred, the jet flow is reversed at one end of the shell and impinged against the workpiece, the spent stream being reformed into the annular jet at the opposite end of the shell member.

摘要： An improved seal arrangement is disclosed for use in batch coil annealing furnaces. The furnace has extending from its base a pair of cylindrical upright supports having exposed membrane engaging seal edges and between which an underpressure chamber is formed. The inner cover which removably rests on the base, has an annular top plate extending radially outwardly from its sidewall adjacent the cover's bottom end. Extending vertically downwardly from the top plate are concentric inner and outer clamp mechanisms which clamp flat annular elastomer seal therebetween. An overpressure chamber is formed between the seal and the top plate and when the inner cover is seated on the base, an underpressure chamber is formed between the seal and the upright supports. A positive pressure is applied to the overpressure chamber and a vacuum is drawn in the underpressure chamber to insure that the seal is forced into sealing contact with the upright engaging surfaces, thus assuring a positive seal of the inner cover with the furnace base.
