Described herein are methods and mechanisms for laterally dispensing fluid to a coke drum in a predictable and maintainable manner that alleviates thermal stress. In one embodiment, the methods and mechanisms utilize a split piping system to dispense fluid through two or more inlets into a spool that is connected to a coke drum and a coke drum bottom deheader valve. A combination of block valves and clean out ports provides a more effective means to clean the lines and allows fluid to be laterally dispensed in a controllable and predictable manner. The fluid is preferably introduced to the spool in opposing directions toward a central vertical axis of the spool at equal but opposing angles ranging from minus thirty (−30) to thirty (30) degrees relative to a horizontal line laterally bisecting the spool. Alternatively, however, fluid can be introduced to the spool tangentially.

Multiple combustion chambers adjacent the heating jacket and hollow drive shaft burn fluidized volatile materials and exhaust combustion fluids through the jacket and shaft.

A pyrolysis plant 20 comprises a grinding pyrolyser 22, being a machine or apparatus in which both particle size reduction and pyrolysis occur simultaneously. Plant 20 also comprises a bin (hopper) 30 for holding wet particulate biomass feedstock. Chute 32 leads from the bin 30 to a biomass dryer 34 which reduces moisture content of the feedstock as low as possible, e.g., to below about 10. Dried feedstock is conveyed from dryer 34 via line 36 to a dried biomass feedstock hopper 38. Dried feedstock is fed from hopper 38 into a chute 40 which leads to an inlet trunnion 42 of grinding pyrolyser 22. A discharge trunnion 44 of grinding pyrolyser 22 leads to a char holder 60 for collecting char particles and a condensation train 62 for condensing vapour generated by the pyrolysis to produce oil.

The invention relates to a method and a device for increasing the coal charging bulk density of a top-loading coke oven. A plurality of coal charging ports are arranged on the top of the top-loading coke oven, and a coal charging car is used to simultaneously charge coal at the multiple coal charging ports; the coal charging car The coal lowering device is equipped with a telescopic vibration compacting device. When coal is loaded, the vibrating head at the bottom of the telescopic vibration compacting device extends into the position of 1/3~2/3 of the coal charging height of the coke oven carbonization chamber. Vibration compacts the surrounding coal material; while coal is being loaded, the vibrating head is lifted synchronously with the rise of the coal loading height. After the coal loading is completed, the vibrating head of the telescopic vibration compacting device continues to lift while vibrating, and reaches the top of the coal material Stop the vibration and retract until the stretchable vibrating compact device is withdrawn from the carbonization chamber as a whole. The invention can vibrate and compact the coal charged into the coking chamber of the coke oven, increase the bulk density of the coal charged into the furnace, increase the coal loading and coke output of the single-hole coke oven, and improve the quality of the coke.
