New burners for annealing and galvanizing lines to recover waste process gases
Fives developed a wide range of AdvanTek® WRT burners for annealing and galvanizing lines to reduce pollutant emissions and improve energy efficiency.
AdvanTek® burners are a proprietary technology of Fives, designed for both reheating and processing line furnaces. The burners, equipped with combustion systems, operate with different fuel types (coke oven gas, natural gas, mixed gas, LPG, heavy fuel oil, domestic fuel oil, etc.).
New AdvanTek® WRT 2.0 burners use basic oxygen furnace (BOF) gas, which is a low heating value gas mainly composed of CO (LHV 7100 kJ/Nm3). A number of tests, conducted at Fives’ Bar-Le-Duc test centre in France, demonstrated an optimum combustion efficiency with 71 % efficiency for BOF gas with NOx less than 50 mg/Nm3 at 3% O2. The combustion efficiency could reach 76% with natural gas.
The AdvanTek® WRT 2.0 burners are available for a power range of 100 - 180 kW (7’’ and 8’’ W-shape radiant tubes), and they can be installed at new or existing annealing and galvanizing lines.
Today, 2 584 AdvanTek® WRT 2.0 burners for natural gas, coke oven gas and mixed gas are in operation worldwide.
