Selective control and regulation of the lift gas in each individual tuyere of the snorkel guarantees an optimized process and a positive effect on the durability of the refractory material. One of our newest developments is our test unit for lift gas, to proof the tightness and flow-rate of the tuyeres and piping of the snorkel assembly before it goes into operation. Gas consumption, flow and pressure can be measured and documented to guarantee 100 % availability and increased functionality of each snorkel. FC TechnikAG RH Lift Gas Tuyeres Test Unit page 1

2 Concept and Specification The standard system is designed as a standalone and plug&play solution, the concept of snorkel testing before using could be implemented in any of our RH Lift Gas control systems. 3 Advantages • Numeric results (comparable indicators) • Standardized testing procedure, independent from operator • Snorkel quality indicators over time • Increase of process reliability • Increase of refractory performance • Low operation costs • Low investment costs • Hertwig GmbH FCTechnik FC Technik AG St. Gallerstrasse 340 CH-8409 Winterthur Tel. +41 52 238 01 75 inforafc-techmk.ch www.fc-technik.com...
