Fluidised-Bed Furnaces TRIZ Cases

Waste heat from hot metal products is stored in a fluidized bed to preheat semi-finished metal products with lower energy use and emissions.

Heated cooling gas bypasses the firing zone to preheat carbonate rock, improving energy recovery while preserving CO₂-rich exhaust separation.

Solid carbon carriers are mixed into DRI before compaction, raising carbon content while cutting melting energy, iron losses, and CO2 emissions.

A gas-permeable dome lets one repurposed blast furnace handle hydrogen-based direct reduction and melting, cutting investment cost and carbon use.

This mineral heat-treatment case recycles offgas to reach at least 75% CO2, supporting liquefaction, separation, or sequestration.

Electrically charged furnace walls apply Coulomb forces to prevent particle sticking and ensure uniform expansion of perlite aggregates.

A detector monitors resin levels in the tank while a controller adjusts valve timing to minimize unreacted monomer loss during discharge cycles.

Granulated particles with a coke core and iron ore coating reduce production costs by eliminating expensive metallic iron oxide powders.

A fluidized calciner positions fuel injection between air intake and bed ports to optimize combustion dynamics.

A porous thermal insulator in the inlet zone reduces heat dissipation to stabilize the fluidized bed temperature and enhance chemical deposition yield.

Mixing nickel oxide ore, carbonaceous reducing agent, and iron oxide creates pellets that prevent grain splitting during smelting at 1400°C.

Segmented cyclones remove fines to stop dust loops and boost energy efficiency.

An injection device uses carrier and shielding gas streams to introduce polymerization catalyst into a fluidized bed reactor.

Diverts shaft furnace top gas to a coal gasifier via an ejector, reducing cleaning costs and power consumption.

A suspension roasting system processes iron and manganese ores through sequential drying, preheating, and reduction stages.

Spacer particles prevent fibre agglomeration during chemical vapour deposition, ensuring homogeneous coating and improved composite mechanical properties.

Granulating fine zinc oxide residues prevents dust entrainment and steam bundle damage in fluidized bed reactors during calcination.

Segmented fluidized bed volume reduces thermal cycle time and operating costs while preventing undesirable surface layer formation during heating.

Cokeless sinter blends repurpose reactive DRI fines as fuel, eliminating coke breeze costs while maintaining ISO tumble strength above 72.
