摘要:
A furnace has a solid fuel hopper 35 above a combustion chamber 10, an ash outlet 11 below said combustion chamber, a combustion gas outlet 11 at or below the level of the combustion chamber, and an auger 22 in an ash chamber 20 below the ash opening 11 to regulate the size of an ash pile 21 below the combustion chamber 10 and hence control the escape of ash or fuel or non-combustibles through the ash opening 11. This enables the combustion gas outlet 11 to be covered by hot coals 53 within the combustion chamber 10 so that any combustion gas from the combustion chamber or any pre-combustion zone must pass through a filter of hot coals 53 before reaching the combustion gas outlet 11.

A wood burning stove (1) with a catalytic combustor (35) and combustor bypass structure (44,45) to increase fuel- burning efficiency and safety by reducing creosote emission by the stove and to provide for safe stove operation even if the catalytic combustor becomes blocked, clogged or otherwise obstructed. The single and multiple bypass structures disclosed utilize bypasses located adjacent to the catalytic combustor or combustors to provide for efficient operation with relatively little smoke flow through the bypass during normal operation and with at least partial combustion of smoke which does bypass the combustor. A smoke relief door automatically actuated by opening the fuel loading door (16) to prevent smoke spillage into the room is also disclosed together with alternative means for supplying secondary air to the stove's combustion chamber in the vicinity of the catalytic combustor.
摘要:
Zur vollständigen Verbrennung von stückigen, aschehaltigen Brennstoffen (1), insbesondere von solchen unterschiedliche Stückgrößen, die einer Verbrennungszone (2) an einem Ende zugeführt und in dieser während des Verbrennungsvorgangs zu einem zweiten Ende wandern, werden am zweiten Ende ankommende unverbrannte Brennstoffstücke von Asche und Feinanteilen abgetrennt (4) und zum ersten Ende rückgeführt (7), um die Verbrennungszone erneut zu durchlaufen. Die am zweiten Ende abgetrennten Feinanteile werden im Austrag (5) vollständig ausgebrannt. Die Erfindung ermöglicht eine Befreiung der Asche von organischen Rückständen bei einer Verkürzung der Verbrennungszone.
摘要:
A scrubber (9) for use in an incineration system to remove particulate materials and provide complete combustion of the combustion gas. The scrubber (9) defines a scrubber chamber (8) having an inlet through which hot combustion gas is introduced and having an outlet for discharge of the gas. Suspended within the scrubber chamber (8) are a plurality of elongated plates (18) composed of a temperature resistant metal, such as Inconel. The plates (18) are arranged in a pattern to provide a tortuous path of flow for the combustion gas through the chamber (8), and prevent direct flow from the inlet to the outlet. In a preferred form of the invention, the plates (18) are arranged in rows with the spacing between plates (18) in one row being aligned with plates in an adjacent row. As the combustion gas flows through the chamber (8), the particulate material will migrate to and collect on the front and rear plate surfaces. During periods of intermittent use, the plates will expand and contract causing the particulate material to fall therefrom for collection in a collection bin (25). The arrangement of the plates also promotes mixing of air with the combustion gas to promote complete combustion of combustibles.

A dry distillation gas producer for producing dry distillation gas is completely separated from a combustion gas burner section for perfectly burning gasified fuel, thereby improving the functions of the respective members as much as possible. Namely, a part of an air supplying means of dry distillation gas producer is improved, an impurity removing tank is provided in an intermediate portion connecting the dry distillation gas producer to the combustion gas burner section to thereby increase the degree of cleaness of the dry distillation gas, and the combustion gas burner section burns the combustion gas with air blown out and fed from openings of first and second air supply portions in a cylindrical burner body, which has been preheated, while fully agitating and mixing the air with the combustion gas, thus realizing the more higher perfect combustion. The dry distillation gasification combustion apparatus, wherein a gas introduction pipe is connected to a dry distillation gas take-out opening of the dry distillation gas producer, the impurity removing tank is provided in an intermediate portion of the gas introducing pipe and the gas burner section is connected to the forward end portion of the gas introducing pipe, characterized in that the dry distillation gas producer is provided at the bottom portion of a tank furnace thereof with an air chamber and an air blow-out portion communicating with the air chamber, air thus supplied flows along a ventilating recessed portion around an air diffusion cap and spreads softly and uniformly over the whole bottom surface, the combustion burner section is provided in the cylindrical burner body thereof with a preheating burner portion, and the first and second air supply portions, the air blown out and supplied from the opening of the first air supply portion is agitated and mixed with the combustion gas in the burner body, air preheated by an air storing layer, which is supplied from the second air supply portion, can be agitated and mixed with the combustion gas in the vicinity of a combustion opening portion.

摘要:
In order to obtain a more uniform and reliable product from burner reactors, there is provided a control for the burner (18) which includes, a sensor (10) to continuously monitor a parameter of the product, suitably temperature, a comparator (24) to output an electrical signal representative of the deviation of the parameter from a reference value, means such as an A/D converter (26) to latch digital representations of the signal amplitude at set intervals and means (30, 34, 35) to adjust the burner (18) in dependence upon the presently latched digital representation and upon the direction of the deviation represented thereby.
