EQUIPMENT & TECHNOLOGY

From a burner design perspective, one of the most significant characteristics of hydrogen fuels is the potential for the hydrogen flame to flashback due to the fast flame speed. Flashback occurs when the flame speed exceeds the feed speed of the fuel and combustion air mixture in a premix burner. Careful consideration needs to be taken when evaluating if the burner design is suitable for hydrogen firing because many burners, even nozzle mix burners, operate with some amount of premixing of the air and fuel, Conclusion Reducing the CO2 emissions of forge and heat treat furnaces is essential to the decarbonization of the industry, and it can be done in several steps. The first step is to maximize the efficiency of the existing furnace by improving air/fuel ratio and furnace pressure control, repairing any damage or degradation, and optimizing operating practices. Next, a regenerative combustion system can be retrofitted to an existing furnace to provide up to an additional 45% decrease in CO2 emissions without sourcing any alternative fuels. Finally, the regenerative combustion system can be relatively easily retrofitted for operation with pure hydrogen to eliminate CO2 emissions, especially if provisions are made in the original design of the system to handle the fuel.
