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.

摘要： An improved process and apparatus for upgrading coal gas to methane is provided by a simple and efficient methanator comprising an open-ended enclosure submersed within a liquid bath and carrying a catalytic insert having increasing degrees of controlled reactivity which the said gas contacts as the gas travels through the enclosure. In the presence of the catalyst, heat is generated from the methanation reaction at a controlled rate and substantially dissipated by the liquid bath so that substantially all the gaseous reductants, CO and H.sub.2, are reacted to methane at a relatively low controlled temperature.

摘要： A radiant tube heater is provided for a gas fired burner which fires heated products of combustion into an inner longitudinally-extending tube which is concentrically pinned to an outer longitudinally-extending tube which in turn is concentrically mounted within a heat transfer, tube which radiates heat to work. The outer and inner transfer tubes have closed axial ends opposite the burner and the inner tube is radially spaced closely adjacent the outer tube to define an annular heat transfer passage therebetween. A specific hole size pattern in the inner and outer tubes in combination with the radial distance of the heat transfer passage insure long path gas flow lengths which promote laminar flow and even heat distribution along the length thereof thus producing a radiant tube which radiates heat uniformly from the heat transfer tube to the work along its length.

摘要： Nitrous oxide emissions are reduced in an industrial thermal process and system which operates a gas fired burner at substantially sub-stoichiometric conditions to produce products of combustion rich in combustibles and control flame temperatures at temperatures which do not exceed predetermined levels. Completion air at stoichiometric proportions is subsequently employed to burn the combustibles. Regenerative and recuperative means to cool gases after each partial combustion step are used to extract heat and use is in conventional heating processes. A novel regenerative heat exchange system is used to extract heat from the gases so that the gases never exceed a temperature whereat nitrous oxide formation tends to occur.

摘要： Method and apparatus is disclosed for thermally decomposing waste material from several batch furnaces plumbed into one afterburner. The afterburner is modified to mix and combust in a controlled manner an otherwise explosive mixture of fumes from several furnaces. The entire system is regulated only by the temperature of incinerated gases from the afterburner. The furnaces are operated in a sequenced, overlapping staged manner to produce a generally constant fume loading permitting significant cost savings in equipment and operation.

摘要： An in situ system for thermally cleansing hazardous and toxic waste disposal sites is disclosed. The system includes a perimeter wall extending into the site which is sealed to a roof structure surrounding the site to encapsulate the site. A plurality of tubes are sunk into the encapsulated site in a geometric pattern and are directly heated to indirectly heat the site. In time, the temperature of the entire site is raised to a level where the waste is volatilized and the volatiles are collected in the roof and subsequently incinerated.
