Scaling factors for hot gas recirculation
WebFeb 15, 2024 · The system layout employing direct combustion just after the SOFC stack and branching of the hot gas stream (combustion gas) results in the pressure drop of 23.5 kPa and parasitic power of 1.04 kW (less than 5% of gross power). These are 2–4 times smaller than those of other layouts. WebThe Energy Policy Act of 2005 established tax credits for energy improvements to existing homes. If you choose a tankless gas water heater, hybrid gas water heater or natural gas tankless water heater which has either an energy factor of at least 0.82 or a thermal efficiency of at least 90%, you may be eligible for up to $300 in tax credits.
