An improved corbel includes a first tier having first blocks and a second tier having second blocks. Each of the first blocks includes a first aperture extending through the block from a first surface to a back surface and a second aperture formed through a top surface of the block, extending into the first aperture. The first blocks are arranged on a substantially planar surface to align the respective first apertures to define a first passageway. Each of the second blocks includes a third aperture extending through the second block from a top surface to a bottom surface. The second blocks are disposed above the first tier to align the third aperture of each of the second blocks with the second aperture of the first blocks to form a second passageway.

The invention provides a method and apparatus for reducing the gas flow velocity in the bottom flue gas system of a coke oven during at least one initial coking operation after the coke oven has been charged with coal (43). The method includes providing a ductwork (96, 98) between a first coke oven having a first coking chamber (18) and a second coke oven having a second coking chamber (18) for transferring at least a portion of the gas from The gas space (41) in the first coking chamber (18) is led into the second coking oven, thereby reducing the gas flow velocity in the first bottom flue gas system of the first coking oven. Reducing the gas flow velocity in the bottom flue has beneficial effects on product yield, coke oven life and environmental control of coke oven volatile emissions.

A method for the pyrolosis of biomass with the aid of a heating element and a feed for guiding the biomass. During pyrolysis, the heating element and the biomass are pressed against each other at a pressure of 5 bars-80 bars. A device for pyrolysing biomasses, comprises a material supply and a pyrolysing station. The material supply comprises elements for generating a pressure of between 5 bars and 200 bars, pressing the raw material which is to be pyrolysed against the pyrolysing station. The pyrolysing station comprises a heating element which is heated to a temperature of between 300° C. and 1000° C. in an operational state.

Autothermal torrefaction devices, which can be either stationary of mobile, are provided and include a torrefaction chamber having a chamber inlet for receiving biomass and at least one chamber outlet. The torrefaction chamber can be substantially surrounded by an exterior housing defining an outer jacket and having a jacket inlet and a jacket outlet. The outer jacket and torrefaction chamber define a space therebetween such that a burner unit including an inlet operatively connected to the chamber outlet and an outlet operatively connected to the jacket inlet allows vapors produced or released from within the torrefaction chamber to travel into the burner unit for combustion of at least a portion of the vapors and subsequently travel through the space between the jacket and the torrefaction chamber to provide heat necessary for autothermal torrefaction of biomass.

Useful byproducts are recovered through the pyrolytic processing of biomass material such as vegetation, paper, or worn tires. The process is conducted in a sealed enclosure under vacuum or other controlled atmosphere. The biomass material is ablated and burned by crunching between counter-rotating rollers whose inner walls have been exposed to a highly heated fluid. The biomass material is preheated by injecting into the feeding duct super-heated: dry steam. A condenser within the enclosure reduces resulting vapors into oils that can be drained from the enclosure pan. Solid combustion residue is abstracted from the enclosure by an Archimedes screw.

The invention relates to a movable slide bed tunnel type coke oven and a use method thereof, and belongs to the field of coal processing and conversion and coking equipment. The coke oven comprises an oven body (48), a front sealing door (7) of the coke oven body, a back sealing door (25) of the coke oven body, a sub-flue (10), a bottom flue (12) and a main flue (6), and is characterized by comprising a coaling preparation chamber (3), a preheating section (50), a carbonization section (51), coke dry quenching section (52) and a coke outlet preparation chamber (23), each part has different structures, and the five parts are connected in series and communicated with each other; and a movable slide bed (37) of loading briquettes or tamping coal materials (44) sequentially pass through the five parts of the coke oven by intermittently moving on a slideway (35) of the slide bed, so that the coal materials are carbonized into coke. The produced coke has uniform specification, large lumpiness, good strength, high heat energy utilization rate, high degree of mechanization, and clean emission of flue gas, and the invention effectively protects atmosphere and water sources and realizes clean production.

A method and system for extracting hydrocarbon fuel products from plastic material provides extraction of usable fuel components from waste plastic materials. The materials (or hydrocarbon portion thereof) are liquified and introduced to a chamber where the liquid material is agitated and a negative relative pressure (vacuum) is applied. The liquid is maintained at a substantially constant temperature and the vacuum draws the off-gas hydrocarbon products out for condensation and further processing, while unconverted char is removed to an ash dump. An auger feed unit with agitator buckets is used to propel the char through a feed while agitating the liquid to enhance the rate of gas removal.
