Pulp Liquors Combustion TRIZ Cases
- Automated Liquor Gun Handling for Safer Recovery Boiler Operation
Automated transfer and control of recovery boiler liquor guns reduces operator exposure to sparks and hot black liquor during spraying and cleaning.
- Recovery Boiler Startup Burner With Swirling Air Nozzles
High-pressure air nozzles create burner swirl without diffusers, reducing smelt fouling and maintenance in recovery boiler startup burners.
- Recovery Boiler Ash Treatment for Chloride-Selective Chemical Recycling
Anion segregation removes chloride from recovery boiler ash purge streams so sodium, potassium, carbonate, and sulfate can be recycled.
- Black Liquor Gasification With Sulfur Fixation for Methane Yield
Supercritical water gasification with a carbon-free hydrogenated fuel boosts methane yield while fixing sulfur in green liquor for recovery.
- Pulping Chemical Furnace Control to Reduce SO3 and NOx
This case controls temperature and air-fuel ratio during sulphur and malodorous-substance combustion to limit SO3 and NOx.
- Kraft Boiler Ash Recovery With Selective Crystallization And Steam Reuse
Controlled precipitation, filtration, and crystallization recover sodium and potassium compounds from kraft boiler ash using residual steam.
- Black Liquor Pyrolysis in Fluidized Bed Reactor
Pyrolyzing black liquor in a fluidized bed reactor using heated solid mass to generate syngas and condensate.
- Low-Temperature Alkaline Pulping of Agricultural Fibers
Alkaline pulping non-wood feedstock at atmospheric pressure removes lignin without generating black liquor pollution.
- Two-Stage Crystallization for High Carbonate Pulping Ash Recovery
Adding sodium sulfate upstream of the second crystallizer forces pure glaserite formation, preventing sodium carbonate contamination in high carbonate ash.
- Direct Steam Generator with CONVAPORATOR Exhaust Separation
A direct steam generator feeds mixed flow into a CONVAPORATOR unit that separates exhaust constituents from condensate, preventing turbine blade contamination.
