Abstract: A stove structure includes a stove body. The stove body has a heat source portion and a wall portion. The wall portion has an inner wall and an outer wall. The inner wall and the outer wall are connected by a plurality of cross-section conducting members. Between the inner wall, the outer wall and the cross-section conducting members is provided with a low conductivity coefficient member. The cross-section conducting members extend the heat conduction distance and decrease the contact area of heat conduction. The lower conductivity coefficient member and the cross-section conducting members lower the heat conduction rate. The temperature of the outer wall is lowered to a second temperature and the temperature in the heating portion of the stove body is kept at the first high temperature.

Abstract: A catalytic tank heater includes a catalytic heating element supported on an LPG tank by a support structure that holds the element in a position facing the tank. Vapor from the tank is provided as fuel to the heating element, and is regulated to increase heat output as tank pressure drops. The heating element is internally separated into a pilot heater and a main heater, with respective separate fuel inlets. The pilot heater remains in continual operation, but the main heater is operated only while tank pressure is below a threshold. Operation of the pilot heater keeps a portion of the catalyst hot, so that, when tank pressure drops below the threshold, and fuel is supplied to the main heater, catalytic combustion quickly expands from the area surrounding the pilot heater to the remainder of the catalyst.

Abstract: A modular oven, such as a batch process oven, includes a standardized set of self supporting, interconnectable panels which, when assembled, from a self-supporting heat containment shell, free of added structural support members.

Abstract: A lining for a furnace chamber which is at least approximately round in cross-section is divided into at least two layers in a radial direction and into at least two portions in an axial direction. A gas seal is disposed between the lining portions, the gas seal being in the form of a foil as of metal and being divided in a radial direction into at least two portions releasably connected together in such a manner as to permit the inner portion to be removed in an axial direction. The gas seal can therefore be composed of individual seal portions, in a radial direction, and can be fitted separately.

Abstract: A stove for heating a room has three coaxially nested tubular columns formed of superposed rings of ceramic material, these columns defining an innermost channel rising above a combustion chamber to carry off evolving flue gases, an intermediate channel in which the flue gases descend, and an outermost channel which is subdivided by a cylindrical metallic partition into an inner and an outer cylinder section, the former serving as a duct for the escape of the flue gases to an elevated exhaust while the latter is traversed by air to be heated through that partition. Passages connecting the combustion chamber with the inner channel section help entrain an initial gas flow, during start-up, through the descending path of the intermediate channel.

Abstract: A ceramic stove that may be supplied in kit form includes a base frame, a cast iron firebox secured on the base frame, a top frame attached to and surrounding the top of the firebox, and ceramic panels extending between and held by the frames in spaced relation from the firebox. The ceramic panels are "ship-lapped" relative to each other and are not cemented or otherwise positively attached to each other. Logs may be fed as fuel into the firebox door from one side of the stove allowing longer logs to be burned. The logs rest on a grate which includes a "shakable" portion for shaking ashes onto an ash pan located below the grate. A separate, small door into the firebox is provided for starting the fire and that door is covered by another, safety door which also closes the space through which the ash pan is removed for emptying. An outer screen gate is provided to overlie the firebox doors and the entire side of the firebox.

Abstract: Heater apparatus is disclosed having a metal firebox in which fuel is burned and an outer ceramic enclosure having ceramic mass walls which absorb excess heat when the heater produces more heat than is required and distributes the heat gradually by radiation after the heater output becomes less than the heat stored in the ceramic mass. The ceramic mass walls are spaced from the metal firebox walls to provide air passages through which air may be circulated by means of a blower so that rapid heating may be had of the interior space when the firebox is initially fired by transferring the heat radiated from the metal walls directly into the room by forced convection. After the interior space is heated to a desired temperature, the blower may be cut off and the room may be heated more slowly at a more even temperature by radiation from the ceramic mass.
