Abstract:
The main objective of this work is to show the behaviour during combustion of oat and triticale straw compared to wheat straw, related to emissions and differences in slagging and fouling of boiler components, working under similar conditions. Several combustion tests have been carried out in a 500 kWth moving grate boiler as preliminary tests before using these biomass straws in a 25 MWe power generation plant. Three combustion tests with a stationary period of 6 hours using wheat, oat and triticale straw are included in this work. Biomass has been characterised physically and chemically and the most important operating parameters have been measured (temperatures, air flow and flue gas composition: CO, NO, SO2, HCl, O2, CO2). SO2 emissions obtained in the combustion of oat and triticale straw are three times higher than those measured with wheat straw (485, 522 and 150 mg/Nm3 at 10% O2 as reference, respectively). HCl also increases in the combustion tests with oat and triticale straw compared to wheat straw (43, 18 and 4 mg/Nm3 at 10% O2 as reference, respectively). Fouling and particle emissions are also higher when burning oat and triticale.
