Oven Incrustations Prevention/Removal TRIZ Cases
- Integrated Deheading Valve Seat for Thermal-Cycle Sealing
A forged one-piece deheading valve seat uses bias members and expansion chambers to maintain sealing through thermal cycling and cut steam leaks.
- Coking Oven Decarbonization via Continuous Scraping
Continuous scraping plates on a pushing ram remove coking deposits during coal charging, eliminating thermal stress from sporadic shutdowns.
- Coke Oven Cover Lifter with Two-Axis Traveling Frame
A two-axis traveling frame compensates for positional deviations in coke oven filling holes, ensuring reliable automatic cover lifting.
- Bicyclic Fouling Inhibitors for Fuel System Surface Protection
Quinoline-based inhibitors dissolve hydrocarbon fouling deposits on metal surfaces, preventing heat exchanger blockage and reducing maintenance downtime.
- Pyrolysis Reactor Char Removal and Gas Temperature Control
Counter-helical blades remove char and a contactor heat exchanger maintains uniform gas temperatures to minimize heat loss.
- De-header Valve Flushing System for Delayed Coking
A three-valve flushing system removes coke fines from de-header valve bonnets before opening, preventing operator scalding hazards.
