A small four-stage gas turbine was directly fired with woodchips using a novel downdraft, gravel-bed combustor for a total 250 hours of tests. The average turbine blockage due to deposits was 0.19 percent per hour. The composition of deposits was studied using plasma emission spectroscopy and x-ray diffraction. The main constituents of the deposits were CaO, MgO, and K2SO4. The deposits contained 5 to 15 percent potassium and 0.5 to 3 percent sulfur.

Abstract Determination of Mg, re, and Zn by inductively coupled plasma emission spectroscopy (ICP) and by the official flame atomic absorption spectrophotometric (FAA) method were compared. Samples were acid digests of commercial fertilizers. Neither matrix effects nor spectral interferences were encountered in the ICP analyses. Linear regression shows that the slopes obtained by plotting ICP results vs FAA results for each element differ from unity by less than 5%.
