Increasing Natural Gas Boiler Efficiency by Capturing

by "surplus" hydrogen and natural gas. Hydrogen is produced on site as a bi-product of the chlor-alkali process. Surplus hydrogen which is either not sold to customers or used within the process is used as fuel. Boiler efficiency, or fuel-to-steam efficiency, represents the difference between the energy input (fuel) and energy output (steam).
