Mar 05, 2012 · After condensing any water vapor in the biogas, the gas can be used as fuel in stoves, water heaters, and boilers. However, the gas burner nozzle must be enlarged to compensate for the low-Btu gas. Tests using biogas as the only fuel in a gasoline engine showed that the energy in 200 cubic feet (5.7 m 3 ) of biogas equaled the energy in 1

Condensing boiler - Wikipedia

The lower the return temperature to the boiler the more likely it will be in condensing mode. If the return temperature is kept below approximately 55 °C (131 °F), the boiler should still be in condensing mode making low temperature applications such as radiant floors and even old cast iron radiators a good match for the technology.
