Above The Orlan Super Gasification Boiler, Illustrating stages of Wood Gasification.Combustion Efficiency and Thermal Efficiency
The overall efficiency of a wood fired boiler is the result of the combustion efficiency and of the ability to transfer the resulting heat to the boiler water. With wood gasification, combustion efficiencies of 90% can be realized. This results in a tremendous amount of heat. With efficient heat exchange to the system water, flue gas entering the chimney can be regulated to around 350 degrees F. The boiler controls could be adjusted for even better thermal efficiency, but this could result in costly damage to the chimney as a result of the condensation of flue gases before leaving the chimney. The best indicator of good combustion is the absence of smoke coming from the chimney. Overall operating efficiency is assured by encorporating a Thermal Storage
system with your wood gasifier.
