Coke Ovens TRIZ Cases

Rotated truncated pyramids with facet plates widen plasma reaction zones and keep waste from clogging the active destruction area.

Oblong foundry coke from a controlled coal blend improves packing density, lowers latent heat loss, and cuts foundry coke production costs.

Limits inert-rich coal outside the semicoke surface-tension range to maintain coke strength when blending multiple coal brands.

Horizontal-oven coking with coal and recycled breeze produces oblong foundry coke that cuts cost, improves packing density, and reduces cupola smoke.

Selective 300-370 nm laser ionization isolates petroleum markers for faster authenticity and adulteration checks without GC column fouling.

Core-shell pelletizing combines carbon and ceramic materials to improve proppant shape, strength, density, and conductivity for fracture imaging.

Cement pre-coating strengthens pyrolysis char surfaces to improve char brick strength, freeze-thaw durability, and environmental impact.

Measure semi-coke surface tension across inert content levels to set coal blend fractions for target coke strength.

This case uses tailored coal blends and coking controls to lower ash fusion temperature and improve carbon transfer in iron-melting cupolas.

Controlled oxygen flow and differential pressure adjust residence time for uniform oxidation of carbonized coal and torrefied biomass.

This case uses semicoke height and stirrer entanglement in a Gieseler plastometer to identify coal that may weaken coke.

Limiting coarse particles reduces oversized voids and increases metallurgical coke strength.

Estimating thermal plasticity via permeation distance resolves insufficient precision in conventional methods, ensuring consistent coke strength.

Segmented flame paths and cooling jackets reduce sulfur dioxide emissions and extend silicon brick service life in low temperature calcination.

Intrinsic viscosity above 2.0 dl/g enables sufficient strength at ordinary temperatures, eliminating expensive heating facilities.

A coal adhesiveness evaluation method measures surface tensions of heat-treated semicokes to determine blend compatibility.

A pyrolysis plant generates hydrogen by converting waste heat into electricity for water electrolysis.

Isomerizing mixed biocomponent and mineral feeds removes oxygen and lowers cloud points below -20°C for cold climate use.

Heating coal and limestone releases carbon dioxide that reacts with coke to form carbon monoxide, converting waste emissions into usable fuel feedstock.

Acute-angle uptake connections reduce pressure drop losses and structural degradation by improving gas mixing and flow distribution in hot common tunnels.

A polymeric compound releases hydrogen at 350-550°C to stabilize metaplast and prevent coke quality deterioration in non-coking coal blends.

A two-stage hydrogenation process uses specialized catalysts to treat light Fischer-Tropsch liquids.

Integrated thermochemical processes decompose coal via solvent extraction to generate high-value chemical products and polymer composites.

Stepwise calcination of bio-oil reduces sulfur and metals content, yielding renewable coke suitable for aluminum smelting.

Processing petroleum coke into a slurry for underground injection captures carbon dioxide and recovers vanadium, avoiding atmospheric emissions from combustion.

Optimized raw coke structure reduces thermal expansion in needle coke while simplifying alkali metal removal from activated carbon.
