Benefits of Stiefel's Gas Burners

Ultra-Low NOx Emissions for Global Environmental Standards

Our gas burners utilize staged combustion with flue gas recirculation to meet <20 mg/Nm³ NOx limit set by CARB and EN 303-5 regulations. A California winery outfitted with our FGR gas burner made regional compliance too easy, decreasing emissions from 80 to a mere 18 mg/Nm³. Supported by hydrogen gas and biogas, these decarbonization measures are promoted at a Swedish plant who switched to biogas and reduced emissions by 40% while maintaining 95% efficiency.

Very efficient and dependable on our glass kiln

Stiefel’s 10MW gas burner is remarkable for its capabilities uniformly heating our kiln within ±3°C. It is a remarkable improvement when compared to the older models’ range of 10°C, leading to a 20% reduction in rejects of pyrometric cones. The ecolow NOx design 30mg/Nm3 also met European guidelines. With full modulation fire setting offers well-balanced control during various stages of firing. Excellent reliability and ease of maintenance—recommendable.

Unmatched Service Low NOx Leaders

Unmatched Service Low NOx Leaders

Our burners take the lead with NOx emissions lower than 20mg/Nm3, preserving all burners. Future proofing against more stringent policies is inevitable. One food plant in California saves $40,000 in penalties incurred during the last three years as their switch was purely based on compliance, cost cutting & avoidance of payment accompanied with significant savings, saying is believing.
Smart IoT Centralized Control

Smart IoT Centralized Control

All burners enable IoT based smart control through PLC based generators. Additional smart controls enable real time monitoring such as flow of fuel being used, waste emission in all out stream processes leading to fuel consumption such as gas and energy. A related engineering firm in Germany controlled the identified parameters enabling controls that reduced energy waste by 19%. Predictive nozzle replacement enabled 35% reduction of downtime.
