The invention relates to a pyrolysis process carried out in the presence of a controlled carbon dioxide environment that allows recovering both the organic portion and the inorganic portion (glass fibers) of a fiberglass-reinforced plastic waste, at an organic yield recovered even higher than 95% by weight and with a suitable for manufacturing new articles, in particular fiberglass-reinforced plastic articles, which provides a profitable to the disposal in dump areas. In particular, the recovered organic products can be mixed as such, at a percentage as high as 20% and more, with a fresh unsaturated polyester resins that is normally used to manufacture common fiberglass-reinforced plastic articles, without worsening its features with respect to articles made starting from fresh resin alone. The glass fibers, which are fully recovered in a combustion treatment after the pyrolysis, are reused fully replacing the corresponding virgin glass fibers, since they are unbroken and perfectly clean in a final step of the process.

A coke plant includes multiple coke ovens where each coke oven is adapted to produce exhaust gases, a common tunnel fluidly connected to the plurality of coke ovens and configured to receive the exhaust gases from each of the coke ovens, multiple standard heat recovery steam generators fluidly connected to the common tunnel where the ratio of coke ovens to standard heat recovery steam generators is at least 20:1, and a redundant heat recovery steam generator fluidly connected to the common tunnel where any one of the plurality of standard heat recovery steam generators and the redundant heat recovery steam generator is adapted to receive the exhaust gases from the plurality of ovens and extract heat from the exhaust gases and where the standard heat recovery steam generators and the redundant heat recovery steam generator are all connected in parallel with each other.

A syngas generator provides a pyrolysis chamber and a steam cracking unit within a heater. A conveyor such as an auger directs input through the pyrolysis chamber where a pyrolysis reaction at about 600 C releases a gas/vapor mixture which is directed through a manifold and through an ejector into the cracking unit which operates at about 1200 C. Syngas from the cracking unit can be cooled, used for co-generation power systems, generate steam, and/or be burned (possibly combusted to generate electricity) with the heat used to heat the heater.

Provided herein is a method for devolatizing a solid feedstock. The solid feedstock is treated to a produce a particle size laying between 1 cm.sup.3 and 100 cm.sup.3. The solid feedstock is passed into a device connected to an outlet of a compaction screw auger comprising an assembly including a solid feedstock injector, a retort, a side arm for injecting a heated gas comprising hydrogen, and a process auger. The solid feedstock is contacted with the heated gas at a temperature of 500 C. to 1000 C. for a time of 60 seconds to 120 seconds, whereby the solid feedstock is converted into a gas stream and a solid stream.

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.

A coke oven includes an oven chamber, an uptake duct in fluid communication with the oven chamber, the uptake duct being configured to receive exhaust gases from the oven chamber, an uptake damper in fluid communication with the uptake duct, the uptake damper being positioned at any one of multiple positions, the uptake damper configured to control an oven draft, an actuator configured to alter the position of the uptake damper between the positions in response to a position instruction, a sensor configured to detect an operating condition of the coke oven, wherein the sensor includes one of a draft sensor, a temperature sensor configured to detect an uptake duct temperature or a sole flue temperature, and an oxygen sensor, and a controller being configured to provide the position instruction to the actuator in response to the operating condition detected by the sensor.

The invention relates to shipbuilding and can be used in reconditioning in order to economize fuel and to increase speed. The technical problem is solved by the shipboard installation of air compressors, air receiver tanks, pass valves, air conduits, air separating conduits, air intakes and air injectors, which are interconnected by air ducts. An air separating conduit is mechanically secured in the bow of the ship and has air injectors secured along the centre thereof up to the stern. The injectors direct a jet of air backwards so that the jet of air thrusts the ship forwards, then the air rises along the sides of the ship, maintaining a layer of air between the ship and the water, thus reducing water resistance. The injectors in the bow direct a jet of air such that the ship is constantly sailing into an air space.

In a processing apparatus, a processing furnace includes a supply port configured to receive a processing target and a discharge port configured to discharge a residue. A temperature control region controls a temperature of an intermediate part between the supply port and the discharge port. A screw rotates to be able to convey the processing target supplied from the supply port toward the discharge port. A first decomposition region includes a first recovery port configured to recover a first fluid obtained by decomposing the processing target in a predetermined region in the intermediate part from the processing furnace. A second decomposition region includes a second recovery port configured to recover, from the processing furnace, a second fluid obtained by decomposing the processing target on the downstream side of the first decomposition region.
