摘要:
A heating apparatus capable of efficiently burning both coal and wood has removable restriction elements for varying the rate of flow of air from an inlet port in the heating apparatus to a fuel holding combustion chamber. The restriction elements are positioned in the air supply path or paths from the inlet port to the fuel holding combustion chamber.
摘要:
A woodburning heating apparatus capable of horizontal and updraft combustion has removable elements positioned within a relatively small enclosed volume to provide efficient and reliable operation in either combustion mode. The removable elements include the wear plates, fireback, and damper assembly. The wear plates and fireback define primary, secondary, and night air supplies for the apparatus. An articulated damper control mechanism provides resistance against impinging combusted gases in at least one position of the damper. The damper construction allows, in either the horizontal or updraft combustion modes, the provision of both top exiting and rear exiting flue connections. Baffles are provided at the combusted gas exit from the primary combustion chamber to uniformly spread the combusted gases exiting the primary chamber over a substantial volume so that localized heating of the apparatus does not occur.
摘要:
An improved wood burning apparatus and method having increased secondary combustion are disclosed. Unburned combustibles from a primary combustion chamber are combined with an oxygen containing gas, such as air, and thereafter pass through a selectively operated electrical heating element which promotes secondary combustion. The combustion products from the secondary combustion are monitored so that if secondary combustion is not sufficiently complete, the heating element is activated to promote increased secondary combustion thereby providing an increased overall efficiency for the heating apparatus.
摘要:
An improved heating apparatus, for example for use as a wood or coal burning parlor stove and providing a significant heat output, has a construction for reducing thermally induced mechanical stress and for enabling the interior baffle assembly components of the apparatus to be removed therefrom, for replacement if necessary, without dismantling the apparatus exterior frame. The elements of the interior baffle assembly are interconnecting and are secured in a mechanically stable configuration by single point connection to the apparatus frame. The apparatus can have primary and secondary combustion chambers and a baffle system for directing flue gases along a circuitous path from the secondary combustion chamber to an exit aperture whereby a significant proportion of the heat of said gases is given up to the apparatus. A vertically oriented downwardly directed two component baffle separates the combustion chambers. A vertically directed, two component fireback separates the primary combustion chamber from the circuitous path. First and second air paths supply air to the primary and secondary combustion chambers respectively. The air provided by the supply conduits to the respective combustion chambers is preheated and the air provided through the second path promotes secondary combustion of the flue gases to thereby increase the overall efficiency of the stove.
