WebJan 9, 2024 · This objective requires the right mix of air and fuel. For perfect combustion, you need about a 10:1 ratio of air to fuel, with safe levels of extra air or “excess air” putting us more into the 13.5:1 to 15:1 range. All gas-fired appliances must have both a flue/chimney to exhaust the leftover products of combustion (outlet) and combustion ... Webcombustion turbine’s natural gas consumption by blending some percentage of the process gas with their main natural gas supply. For example, GE developed a fuel blending system allowing a blend of hydrogen and natural gas to be burned in a 7FA gas turbine with the DLN 2.6 combustion system. Typically, GE’s 7FA heavy duty gas
