  • Patent number: 6244197
    Abstract: Chimney-like cooling passages that have opposite outlet and inlet end regions open to ambient air also have central regions that extend through heated components of industrial furnaces. The passages preferably are defined by conduits that are oriented and configured in a manner that enables thermally induced flows of ambient air to self establish through the conduits to cool the furnace components once the furnace components become heated. The passages function like chimneys, with each having its outlet located higher than its inlet so that ambient air will effectively rise as it flows from the inlet to the outlet. The passages may provide increases in cross-sectional area somewhere along their lengths so that heated ambient air expanding in the passages is encouraged to discharge from the less restrictive, larger area outlets rather than from the smaller area inlets.

  • Patent number: 5230617
    Abstract: A system for cooling a single or plural zones of the exterior of a furnace or similar hot device, e.g., kiln, calciner, etc. Each zone is cooled by a respective cooling assembly. The operation of the assemblies is effected by a common control system. Each cooling assembly comprises a shroud, an induction cooler, e.g., an exhaust fan, and at least one atomizing spray nozzle. The shroud is in the form of a jacket disposed over the associated exterior zone of the furnace and is spaced therefrom to form a cooling chamber therebetween. The exhaust fan is coupled to the shroud for inducing the flow of cooling air through the cooling chamber so that it absorbs heat from furnace's exterior. The atomizing spray nozzle is also coupled to the shroud and to a water and an air supply for introducing atomized droplets of water into the chamber, whereupon the droplets vaporize to absorb heat from the furnace's exterior. The exhaust fan vents the air and steam from the shroud means.

    Abstract: This invention comprises a door for gas-tight sealing engagement in an access opening in environments involving high temperature. In one embodiment, the door is a boiler access door provided through a waterwall in a boiler, and includes a tapered insulation plug for sealing engagement in a tapered opening in the waterwall. In a preferred embodiment, the tapered sides are stepped and the insulation comprises multiple layers, which may be of different grades of insulation material.

  • Patent number: 4437415
    Abstract: A burner block for an industrial furnace is resiliently seated in a hollow annular member, the latter being made of a metal such as stainless steel and the burner block being made of a refractory material. Because of the resilient mounting, the burner block is seated firmly in the annular member even though these two parts have different rates of thermal expansion. In addition, a cooling fluid is circulated within the interior of the annular member to cool the latter so that the furnace may operate at a temperature which is well above the temperature at which the annular member loses its structural integrity. All of this permits the burner block assembly to be mounted effectively on the metal outer shell of the furnace without relying upon the refractory lining of the furnace for support.

The periphery of the access door is slotted for internal convective cooling of the door. Ambient air enters the air space beneath the firebox, flows rearwardly, then upwardly behind the firebox and forwardly along the top and sidewalls of the firebox to progressively heat the air and to cool the outer jacket. A reflective intermediate baffle between the jacket and the side and rear walls of the firebox further cools the jacket. Heated air returns to the room via sidewardly-directed outlet slots along the upper and frontal margins of the jacket sidewalls. A pedestal supports the jacketed firebox above the floor. The pedestal contains a first conduit for introducing ambient air into the air space and second conduit for introducing outside combustion air into the firebox. The pedestal also houses a blower for blowing air into the air space.
