Abstract:
In this study the effect of the application of different fertilizer on the fuel and combustion characteristics of SRC willow is investigated. The willow has been sampled in autumn and spring for two years and their combustion characteristics and their corresponding combustion properties and ash related problems have been studied. N as NH4(NO3) was applied to two of the treatments with K in the form of K2O added to one and SO3 in the form of (NH4)2SO4 added to the other. Sewage pellets were applied to the third treatment since willow has the tendency to remediate sewage sludge. In general the N, S and ash contents and the alkali index for the leaves was higher than the stems. The potassium concentrations in the ash are higher in the stems than the leaves but the reverse is true for sodium concentration. However the alkali index for leaves was higher because of the higher ash content. Initial conclusions can be made that later harvest times are desirable for ash-related problems but not for NOx formation.
