    Abstract: A thermal expansion valve comprises a metal tube for flowing a fluid therethrough, and a metal rod fixed only at a first end in the tube and disposed wholly within the tube, the metal tube having a greater coefficient of expansion than the metal rod. A plug having an orifice therethrough is disposed in the tube proximate a free end of the rod. Lengthwise thermal expansion and contraction of the tube and the rod caused by the temperature of the fluid in the tube and around the rod causes the free end of the rod to retreat from the plug to increase flow of the fluid therethrough, and causes the free end of the rod to approach the plug to restrict flow of the fluid therethrough, respectively.

    Abstract: A burner assembly has a combustion chamber in which combustion takes place in an elongate centrally disposed combustion tube. An outer housing encases the combustion tube and provides an annular space between an inner wall of the housing and the combustion tube. Part of the exhaust gases exiting from the combustion tube are diverted from the downstream end thereof to be returned through the annular space to the upstream end of the combustion tube. Fuel is injected into the diverted exhaust gases, volatilized when in liquid form and mixed with the diverted gases. The fuel and gas mixture is further combined with a buffer gas and becomes entrained into and mixed with a high velocity of combustion air which is injected into the upstream end of the combustion tube. The flame temperature may be monitored and the quantity of the buffer gas added may be controllably varied based on temperature readings from the monitoring process to minimize the generation of nitrous oxides.

    Abstract: A forced hot air furnace having a continuously wet recuperative heat exchanger. The recuperative heat exchanger is positioned in the hot air chamber at an upward incline from the firebox to the outside flue. Inclined positioning enables heat exchanger condensate to drain counter to combustion products. Condensate is collected in a reservoir located in the firebox. Combustion products flow over the reservoir thereby becoming elevated in dew point before entering the heat exchanger. Consequently, the amount of condensation formed in the heat exchanger is substantially increased over conventional heat exchangers. Condensate will form along the entire length of the heat exchanger resulting in all wet operation. In another embodiment, continuously wet operation is achieved without a water reservoir. In still another embodiment, the continuously wet recuperative heat exchanger is coupled to the output of a non-recuperative heat exchanger. In an alternate embodiment, a continuously wet recuperative heat exchanger is utilized to heat a liquid.

    Abstract: Gas-solids transport and heat exchange techniques are disclosed wherein solid particulate material is circulated in a "figure 8" or a circular flow path for selective contact and/or direct heat exchange with gaseous media. The particulate material is introduced into streams of gaseous media at spaced locations in the flow path and subsequently separated from the gaseous streams following contact and/or heat exchange therewith. The gaseous streams are maintained separate from one another by loose packed bed columns of particulate material formed in the flow path and used to introduce the particulate material into the gaseous streams. The flow rate of the particulate material is regulated by the controlled biasing of particulate material from each of the columns thereof directly into the gaseous streams, and the particulate material is circulated solely through the use of the gaseous media and the force of gravity. The particulate material is circulated in cocurrent relationship with each of the gaseous streams in figure 8 flow path systems and, in circular flow path systems, the particulate material is circulated in cocurrent relationship with one of the gaseous streams and in countercurrent relationship with the other of the gaseous streams. In heat exchange applications, heat transfer between the streams of gaseous media is provided as a function of the flow rate of the particulate material and the relative flow rates of the streams of gaseous media.
