Abstract:

During the European demonstration project Bioelectricity Crops, two energy crops, Triticale (Triticosecale Wittm.) and Brassica carinata, were evaluated as potential solid biofuels for the biomass power plant of 25 MWe located in Sangüesa and operated by the company Acciona Energia (Spain). Objectives of the experiment was to check at a pilot scale the combustion and emission parameters of both energy crops before evaluating them in the industrial biomass power plant. The raw materials were characterised at the lab scale for a range of parameters. During the combustion tests, ash accumulated under the grid of the boiler and volatile ash retained in the multi­cyclone filter were also sampled and then analysed at the lab scale. Regarding the emissions, a specialised lab (APAVE) carried out the analyses on-line during 3 runs of 30 to 45 minutes. The high amount of ash and fines particles observed with both biomasses was related to their characteristic. Slagging was observed in the boiler only for triticale. Ash coming from the boiler showed a low rate of unburned elements due to good combustion conditions. Their composition showed especially low nitrogen content and expected high concentration in potassium, in phosphorus and in silica for both biomasses. Triticale and carinata ash was found to differ for sulphur. Ash retained by the multi-cyclone filter showed relatively similar composition excepted for unburned elements (higher level), silica (lower content) sulphur and chlorine (higher contents). Regarding the emissions, all the measured undesirable elements were found under the requirements for both biomasses excepted for the fine particle contents (4 times over the limit for triticale). They showed also better results than the references obtained with wood. These tests delivered useful data on the combustion performances of two new energy crops and allowed further experiments in the industrial plant of Sangüesa.
