  • Patent number: 6026804
    Abstract: A fluid heater includes a housing, a burner unit disposed in a bottom portion of the housing for burning combustible fuel, a combustion chamber disposed within the housing where the fuel is burned and a heat exchanger disposed substantially within the housing over the combustion chamber. The heat exchanger absorbs heat generated from burning the fuel and conducts the heat to a fluid to be heated. The heat exchanger includes a pair of spaced, parallel, stainless steel tubesheets with a plurality of tubes running therebetween and sealingly received within mating apertures in each of the tubesheets. A plastic front header and a plastic rear header are removably attached to the tubesheets distal to said tubes. The apertures in the tubesheets preferably have forged flanges for increasing the surface contact area with the heat exchanger tubes. The heat exchanger is corrosion resistant due to the combination of corrosion-resistant tubesheets, tubes and headers.

  • Patent number: 5993194
    Abstract: Systems and methods are disclosed that optimize the combustion process in various reactors, furnaces, and internal combustion engines. Video cameras are used to evaluate the combustion flame grade. Depending on the desired form, standard or special video devices, or beam scanning devices, are used to image the combustion flame and by-products. The video device generates and outputs image signals during various phases of, and at various locations in, the combustion process. Other forms of sensors monitor and generate data signals defining selected parameters of the combustion process, such as air flow, fuel flow, turbulence, exhaust and inlet valve openings, etc. In a preferred form, a neural networks initially processes the image data and characterizes the combustion flame. A fuzzy logic controller and associated fuzzy logic rule base analyzes the image data from the neural network, along with other sensor information.

  • Patent number: 5992407
    Abstract: A miniature gas stove support mainly including lower seat and upper locating ring distantly connected to one another by vertical bars, three equally spaced outward inclined legs connected to a bottom of the seat, and multiple petal-shaped wind shielding members connected to and along a top of the locating ring. Bolts are threaded downward to screw the locating ring and the vertical bars together while head portions of the bolts project from the locating ring to adjustably support a cooking utensil above a burner of the miniature gas stove. The petal-shaped wind shielding members fixed along the locating ring effectively shield the burner from wind to avoid undesired extinguishment of fire.

  • Patent number: 5975071
    Abstract: A portable heating device includes a reservoir having a lid which closes the reservoir during heating. A heat plenum assembly is provided having a firebox disposed underneath the reservoir. The firebox communicates with a burner tube for introducing heat to the lower surface of the reservoir. Tertiary heating of the side walls of the reservoir are provided, as well as heating along the length of the reservoir bottom surface. A deflector at one end of the passage way improves the distribution of tertiary heat by directing heat within the passage way towards each of the corners of the reservoir. A convective air curtain is provided by a doubled walled outer lining which encloses the heat plenum and reservoir. Efficient heat transfer is accomplished between the firebox and reservoir while maintaining the outer surface cool to the touch.

  • Patent number: 5957123
    Abstract: A generally rectangular metal cooking pan and skirt assembly in which the pan is mounted above the skirt and is joined thereto. Disposed within the skirt is a gas or electric heating unit which generates heat that is applied to the pan to cook meat or other food placed therein. Because of thermal stresses created in the pan by the applied heat in the course of a cooking operation, the pan is susceptible to warpage and possible damage. To constrain such warpage there is provided a reinforcing bar extending diagonally across the rectangular skirt and being welded at its end to opposing diagonal corners of the skirt. The diagonal bar defines a constraining bridge that maintains the geometry of the assembly in the course of a cooking operation to prevent it from exceeding its elastic limit and permanently deforming the assembly.

  • Patent number: 5954046
    Abstract: A system for heating and ventilating a building which includes a generally peripheral foundation element which supports the external walls of the building. Room air is heated and circulated below the floor and up through floor openings at the external wall. A barrier is connected to the foundation wall so as to span the area enclosed by the foundation wall at a level beneath the floor. Exhaust air is conducted to a region beneath the barrier for surface-enlarged contact with the underside of the barrier. The foundation element and/or the base that supports the foundation element is permeable to air along essentially its full length beneath where the foundation element connects with the barrier and exhaust air flows out through the foundation element or its supporting material while effecting an exchange of heat therewith.
