The invention presents a covered cavity kiln pyrolyzer with modulated means of rotation, to promote mixing and exposure of the biomass to heat, thereby allowing complete and efficient pyrolysis of biomass therein. The invention has a portal arrangement for simultaneous entry of fuel and air alongside the exit of emissions and flames to a separate hood structure. In addition to rotational modulation for mixing, the rotational capabilities of the kiln also permit the removal of processed charcoal when the portal is turned downward. The invention also has a system of internal prongs for mixing and sifting removal of char, as well as automated fuel delivery mechanisms and a system of openings to allow insertion of pipes and sensors into the kiln for monitoring and for additional delivery of reagents for better modulation and efficiency by a user during the pyrolyzation process.

Systems and methods for particle leak detection generally include a separation or collection device configured to filter particulate from a stream and a detection device downstream of the separation or collection device. The detection device can be positioned to detect particulate that passes the separation or collection device and can include a probe configured to detect the solid particles. The particle leak detection systems can be configured to be disposed on moveable systems, such as moveable systems in coke oven operations.

The present technology is generally directed to systems and methods for optimizing the burn profiles for coke ovens, such as horizontal heat recovery ovens. In various embodiments the burn profile is at least partially optimized by controlling air distribution in the coke oven. In some embodiments, the air distribution is controlled according to temperature readings in the coke oven. In particular embodiments, the system monitors the crown temperature of the coke oven. After the crown reaches a particular temperature range the flow of volatile matter is transferred to the sole flue to increase sole flue temperatures throughout the coking cycle. Embodiments of the present technology include an air distribution system having a plurality of crown air inlets positioned above the oven floor.

The present technology is generally directed to methods of increasing coal processing rates for coke ovens. In various embodiments, the present technology is applied to methods of coking relatively small coal charges over relatively short time periods, resulting in an increase in coal processing rate. In some embodiments, a coal charging system includes a charging head having opposing wings that extend outwardly and forwardly from the charging head, leaving an open pathway through which coal may be directed toward side edges of the coal bed. In other embodiments, an extrusion plate is positioned on a rearward face of the charging head and oriented to engage and compress coal as the coal is charged along a length of the coking oven. In other embodiments, a false door system includes a false door that is vertically oriented to maximize an amount of coal being charged into the oven.

Pyrolysis apparatus (10) for processing shredded waste material, such as plastic and/or rubber waste, in which apparatus the material is processed continuously in a pyrolysis apparatus (10) that includes a feed device (30), a reactor (30) and an outlet portion (40) that have been equipped with conveyors, such as screw conveyors, and that can be used continuously. The screw (23) of the feed device (20) is at least partially placed in a liquid (22), which forms an air trap to prevent air from entering into the reactor. The outlet portion has a condensing collecting canopy (45) which is used to condense into liquid and recover the vapor formed in the reactor.
