“…There is information available for biomass cofiring in general (Hughes 2000;Tillman, 2000a;Tillman, 2000b), however, not specifically for algae cofiring. Hence, for electricity production using algae cofiring, CO 2 and NO x combustion-related emissions attributable to the algae were based on their carbon (56% on a dry solid basis) and nitrogen (4% on a dry solid basis) contents.…”

The blending of coal with biomass can lead to synergistic combustion behaviors. The combustion profile of two biomass sources, two coals and subsequent blends was studied using thermogravimetric analysis (TG). Ignition and burnout performances were identified and calculated from thermal curves. The comprehensive combustion performance index S was calculated from the thermogravimetric curves. CO 2 and CO concentrations were also studied via on-line analysis of TG-Fourier transform infrared spectroscopy. The results indicated that complicated chemical processes took place when coal was combusted with biomass, as compared with coal or biomass only. The lower ignition temperatures and higher volatility of biomass significantly improve the combustion behavior of coal. However, when biomass content in the blends exceeded 10 %, ignition and burnout performances were minimally affected. The combustion index S appears to give a more comprehensive description of the combustion process. The results from CO/CO 2 ratio also support the combustion behavior for the blending of coal and biomass. For this study, the addition of 10 % of biomass would be the optimum recommended combustion ratios for coal and biomass blends.

“…The relative low investment cost for implementation and possibility to use seemingly unwanted side products of different processes related to agricultural, industrial or municipal activity were one of the main drives for such trend. There are also significant advantages over conventional coal fuels like lower sulphur and nitrogen content, similar qualitative composition for coal and reduction in waste storage scale [1][2][3][4][5].…”

Abstract. Biomass combustion stands among various technologies pointed at fossil fuels consumption decrease. Biomass can be found in very diversified sources spread more evenly across the globe, can be burned with use of traditional combustion solutions and is more CO 2 neutral in combustion than their fossil fuel counterparts. On the other hand biomass has several problems with composition that despite its potential diversity. Problem of excess moisture can be already solved by material selection or by preliminary pyrolysis. The main problem concerns however biomass ash composition. Biomass ashes are more prone to have higher quantities of potentially corrosive components than their coal counterparts. The example of such constituents are alkali metals, sulphur and chlorine. Ash basic composition is also important due to various ash properties like its melting temperature and slagging or fouling tendencies. To address the problem, several indices for fast properties prediction and earlier problem identification can be appointed. This work concentrates on ash quality evaluation for potentially attractive biomass fuel from nutshell materials and their corresponding char obtained by pyrolysis in 300, 450 and 550 o C. Pistachio and hazelnut shells with their chars will be analysed for corrosive compounds and their potential influence on combustion process.
