Abstract:
A small scale, residential (20-200 kWth) heating system fueled with Fast Pyrolysis Bio-Oil (FPBO) has been developed. Because the properties of FPBO deviate from conventional heating fuels, available systems need to be modified to allow the use of this renewable fuel. Supported by detailed kinetic models, spray analysis and CFD modeling, a modified burner was designed, constructed and tested to achieve stable combustion on 100% FPBO as well as blends with up to 30 wt.% bioethanol. The burner was fitted on a standard condensing boiler system and connected to a dedicated FPBO feeding skid. Flue gas emissions below the (German) limits for pellet boilers were achieved. Typical values observed in the current system are 10-20 ppm CO and 200-300 ppm NOx at an oxygen content of 3 vol.%. A prototype demonstrator with a capacity of around 40 kWth has been installed at BTG in cascade with two natural gas fired boilers.
