Web17 feb. 2024 · Blending hydrogen to natural gas must be made slowly to avoid transient H 2 concentration peaks and other disturbances that may occur. GERG recommends injection rates slower than 2% per minute. WebWe observe that hydrogen addition to natural gas tends to decrease the emissions of CO and unburned hydrocarbons from a standard industrial nozzle-mix gas burner, but increases the NO x emissions. Further, a flameless burner can be driven out of the flameless mode by high percentages of H 2, with a concomitant increase in NO x emissions. split master spreadsheet into multiple sheets https://amgsgz.com
