摘要： A bio-mass burner construction for alternate fuels at temperatures from about 1,800 degrees F. to about 2,800 degrees F. to replace oil and gas burners. The burner utilizes a first burning chamber having a falling fuel, entrained bed zone positioned above a traveling grate having a porous metallic woven belt. Primary air is directed through the porous belt to establish an oxygen-starved first burning chamber. A second burning chamber in fluid communication with the first burning chamber, but having a restricted diameter, effectively provides a hot air gas nozzle. The second burning chamber receives a superheated secondary air source from cored apertures in interfitting refractory block members which provide a refractory lining for a portion of the first burning chamber and receive heat from the first burning chamber to heat the secondary air. In larger sized units a plurality of conveyors constitute the traveling grate with the conveyors being arranged in head-to-head stepped relationship so that unburned fuel received by gravity from the entrained bed zone is agitated or jostled to enhance its burning. An automatic ash removal system receives ashes from the traveling grate in a U-shaped trough through which travels a heavy duty auger. A water misting bath is provided in the U-shaped trough to lower the ash temperature.

摘要： A thermally turbulent combustion system for combusting solid fuel which includes a generally cylindrical, longitudinally extending stationary combustion chamber formed by a plurality of interconnected circumferential cooling pipes and fuel transport means provided adjacent the bottom of the chamber along the length thereof. A water cooled door may be provided at the inlet end of the chamber. The width of the chamber is greater than the width of the fuel path. A plurality of headers are connected to the pipes to supply and discharge cooling fluid thereto and therefrom. In one embodiment, the combustion chamber has a symmetrical cross-sectional configuration and the transport means is positioned centrally along the length of the bottom thereof. In another embodiment of the system, the chamber has an asymmetrical cross-sectional configuration and the transport means is positioned adjacent one side along the length of the bottom of the chamber. The combustion system is useful as part of a balanced draft boiler system having forced air handling means and induced air handling means.

摘要： A compound resource recovery furnace having a plurality of furnace chambers including an inner product chamber, an outer incineration chamber, and an intermediate chamber in surrounding relation to the product chamber and within the incineration chamber. The inermediate chamber has a slotted wall made from insulating refractory material and movable damper plates which provide closures for the slots. A temperature responsive control system regulates the damper plates to allow heat to escape from the intermediate chamber to the incineration chamber when the temperature in the incineration chamber drops below a predetermined temperature.

摘要： An incinerator with a moving-bed stoker in which a chain conveyor is inclined in the direction of its movement and a plurality of fuel- or fire-bed members L-shaped in cross section are mounted on the links of the chain conveyor, whereby a step-like moving fuel- or fire-bed is defined. Each fuel- or fire-bed member comprises an upright or vertical plate and a horizontal plate and combustion air injection holes are formed through the upright or vertical plate so that the foreign matter such as ash, metal pieces or the like as well as the molten ash produced as the result of the combustion of waste with a low melting point can be prevented from falling through the combustion air holes into the stoker.

摘要： A method and apparatus for incineration of combustible material including the processing of sewage sludge from wastewater treating plants and the initial activation and regeneration of activated carbon granules or powder used for adsorption in wastewater treatment and the like. The method is carried out by supporting the combustible material in an enclosure, directing infrared radiation on the material, and controlling the atmosphere in the enclosure around the material for purposes of controlling the oxidation process initiated by the heat from the infrared radiation. In a more specific form the method includes a step of counter-flowing combustion gases over the combustible material to supplement the infrared heat. The combustion chamber of the enclosure is operated at a slight vacuum to minimize escape of noxious odors. In practicing the method with sewage sludge, the sludge is first pre-dried and fragmented before introducing it into the enclosure. In the enclosure the sludge is burned by the combined heat of the infrared and counter-flowing combustion gases to incinerate all combustible material in the sludge. When applied to carbon particles, the method comprises the burning of bonding agents and other foreign matter present in the carbon when the carbon is initially activated, and when the method is applied to regeneration or reactivation of the carbon, the contaminants on and within the carbon resulting from the adsorption process are burned from the carbon with the atmosphere controlled to prevent oxidation of the carbon itself.
摘要翻译： 一种用于焚烧可燃材料的方法和装置，包括处理来自废水处理厂的污水污泥以及用于废水处理等中的吸附的活性炭颗粒或粉末的初始活化和再生。 该方法通过将壳体中的可燃材料支撑在壳体上，将红外辐射引导到材料上，并且控制围绕材料的外壳中的气氛，以便控制由红外辐射引起的热量引发的氧化过程。 在更具体的形式中，该方法包括将燃烧气体反向流过可燃材料以补充红外热的步骤。 外壳的燃烧室在轻微的真空下运行，以尽量减少有害气味的逸出。 在实施污水污泥的方法时，首先将污泥预先干燥并分散，然后再将其引入外壳。 在外壳中，污泥通过红外线和逆流燃烧气体的组合热量燃烧，以焚烧污泥中的所有可燃材料。 当应用于碳颗粒时，该方法包括当碳最初活化时燃烧粘合剂和存在于碳中的其它异物，并且当该方法应用于碳的再生或再活化时，碳和/或碳内的污染物 由吸附过程产生的碳被气体控制，以防止碳本身的氧化。

摘要： The present invention relates to a furnace for combustion of refuse, especially household and industrial refuse, and of the type comprising a horizontal chute with a transporting gate arranged longitudinally in said chute. The object of the invention is to provide a furnace of the above stated art which can be erected and installed easily and for lowcosts, and which also can be arranged in unused brick kilns, especially such of the Hoffmann-type. Another object of the invention is to provide a furnace in which complete combustion of the refuse is secured maintaining a relatively low-temperature under and in the grate itself, but maintaining a maximum temperature in a range of about 800* C. in order to remove odor from undesired odors in the flue gas. These and following objects are apparent from and are achieved with the following disclosure.
