Within the scope of the project activities during the year 2013, the most important impact is expected from a thorough combustion analysis of two different formulations of liquefied wood in a laboratory turbine engine. First a formulation comprising liquefied wood produced from wood, glycerol and di-ethylene glycol in ratios 1:1,5:1,5 was tested, and second formulation comprising liquefied wood produced from the same feedstock with ratios 1:1:1 was tested. Although successful establishment of continuous combustion process of formulation with an 8% increase in wood content represents an important scientific achievement by demonstrating feasibility of the use in turbine engines, a wide impact on society is expected to arise from the comparison of the two formulations. The compared results indicate that the elevation of wood content in an innovative fuel, albeit the significantly increased viscosity, is indeed a correct step towards an increase in economic value of the fuel by elevating the content of its lowest priced component – the wood. The results also indicate that NOx emissions generally remain in a similar concentrations interval for both formulations whereas the CO emissions are significantly higher than with formulation with 25% wood content. Results indicate that CO concentration significantly reduces with increasing TIT, thus achieving sufficiently low CO emissions in a commercial turbine engines is still feasible with formulation 1:1:1.
