Stiefel's Industrial Burners advantages

Energy Saving and Performance Combustion Fuel Efficiency

Through Stiefel incinerators commonly used in industries, up to 98% of thermal energy is efficiently utilized through heat recovery systems and premixing separate regenerative heaters. Our modules control air-fuel ratios so same level of fuel combustion yields to maximums of heat given out. For example, 28% of natural gas falling consumption was achieved in a Dutch dairy plant when they implemented our condensing burners that harness heat from flue gases. In a functioning context our 5MW oil burners with high-pressure atomization of 200 bar yield only of 40% of unburnt carbon in the steel mill reheating furnaces while simultaneously attaining enhanced sustainability and efficiency.

Stiefel’s dual fuel burners allow easy switching between fuels which is convenient for facilities that face fuel supply inconsistencies or unstable fuel pricing. The separate fuel injectors (gas and oil) permit instantaneous switching without any downtime, for instance a hospital boiler can seamlessly transition from natural gas to diesel during a gas shortage while still providing heat. For a resort in the Caribbean, our dual fuel burner lowered energy expenses by 18% while keeping NOx emissions under 50 mg/Nm³ by using bio-diesel first when available. The advanced control systems of the burners with variable speed drive allow stratified combustion and variable air–fuel ratio control to optimize combustion parameters, guaranteeing efficient combustion for the fuel type used while meeting local environmental requirements.

Frequently Asked Questions

Which fuel types are accepted in Stiefel’s burners

Stiefel's burners accept several fuels including natural gas, LPG, fuel oil (HFO/MDO), biomass, waste oil, and subsidized fuels like biogas and blends with hydrogen (up to 20%). The burners are designed with adaptive control systems that provide constant monitoring and air-fuel ratio adjustments for different fuels, stable combustion is ensured. For instance, the dual-fuel burners for a resort in the Caribbean can completely switch from gas to diesel in 5 minutes during outages and keep NOx emissions to ≤50 mg/Nm³.
