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 fuel lines are constructed to withstand the extreme temperatures and pressure of hot fuel delivery systems. The 316 stainless steel fuel lines will not corrode from sulfuric acid present within bio-diesel, and the nitrogen purge ports within the double wall design allow for early leak detection within hazardous fuel systems. For a maritime boiler operating on heavy fuel oil, swivel union fuel lines reduced installation time by 50% over traditional flanged systems. The PTFE-lined hoses also eliminated permeation in LPG applications. All fuel lines are tested hydrostatically at 1.5x rated pressure and helium mass spectrometry leak tightness testing of ≤1x10⁹ Pa·m³/s. The red fuel oil and blue gas color-coded lines increase safety as well as maintenance efficiency in complex burner systems.

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.
