“…Recently, in addition to boilers, diesel engines, and turbines, Stirling engines, which are suitable for small-scale combined heat and power (CHP) production, have been considered for the application of bio-oil as an alternative fuel. Bandi and Baumgart 43 at ZSW (Germany) used bio-oil in a 25 kW Stirling CHP unit supplied with a modified FLOX (flameless oxidation) burner that included an air pressure atomizer. The tests proved that bio-oil could be efficiently burned in such a burner without noticeable residues and with emissions below German standards.…”

Fast pyrolysis of biomass is one of the most recent renewable energy processes to have been introduced. It offers the advantages of a liquid product, bio-oil that can be readily stored and transported. Bio-oil is a renewable liquid fuel and can also be used for production of chemicals. Fast pyrolysis has now achieved a commercial success for production of chemicals and is being actively developed for producing liquid fuels. Bio-oils have been successfully tested in engines, turbines, and boilers, and have been upgraded to high-quality hydrocarbon fuels, although at a presently unacceptable energetic and financial cost. The paper critically reviews scientific and technical developments in applications of bio-oil to date and concludes with some suggestions for research and strategic developments.

“…They are designed to run on heavier fuels with efficiency >1 MW [103], more like pyrolysis oil properties compared to distillate fuels used in gas turbines or diesel engines. In a FLOX burner coupled with a very small Stirling CHP unit, Bandi and Baumgart [107] tested pure pyrolysis oil. Pyrolysis bio-oils can only work in the burner after sufficient preheating of the burner with emissions below German specifications for diesel engines within the similar load and power range.…”

Bio-oils produced by biomass pyrolysis are substantially different from those produced by petroleum-based fuels and biodiesel. However, they could serve as valuable alternatives to fossil fuels to achieve carbon neutral future. The literature review indicates that the current use of bio-oils in gas turbines and compression-ignition (diesel) engines is limited due to problems associated with atomisation and combustion. The review also identifies the progress made in pyrolysis bio-oil spray combustion via standardisation of fuel properties, optimising atomisation and combustion, and understanding long-term reliability of engines. The key strategies that need to be adapted to efficiently atomise and combust bio-oils include, efficient atomisation techniques such as twin fluid atomisation, pressure atomisation and more advanced and novel effervescent atomisation, fuel and air preheating, flame stabilization using swrilers, and filtering the solid content from the pyrolysis oils. Once these strategies are implemented, bio-oils can enhance combustion efficiency and reduce greenhouse gas (GHG) emission. Overall, this study clearly indicates that pyrolysis bio-oils have the ability to substitute fossil fuels, but fuel injection problems need to be tackled in order to insure proper atomisation and combustion of the fuel.

“…Nitrogen Oxide (NOx) emissions from pyrolysis oil were found to be only slightly higher than those from LFO [27, 34-36, 53, 58]. it to a SOLO TM stirling engine [62]. The FLOX (flameless oxidation) combustion process uses very strong exhaust gas recirculation and combustion air preheating to produce a more uniform combustion environment.…”
