Abstract:

This paper presents the recent findings of research into direct biomass co-firing on a large combustion plant (LCP) – 226 MWe CHP Tuzla Unit 6, owned and operated by EPBIH power utility. The co-firing test were performed with locally sourced brown coal and waste woody biomass, in this case chips and sawdust. Comparison of results of the lab-scale tests and real tests on LCP were provided in the work. Outcome of the LCP tests was to find optimal blend of the coal and waste woody biomass that should substitute coal in coal-fired CHP Tuzla Unit 6 power station. The co-firing trials were conducted over a range of the following process variables, namely biomass percentage in the fuel mix (10, 15 and 20%t), operation load and process temperature, overall excess air ratio and air distribution. Neither of the three used coal-biomass blends has produced any significant ash-related problems. The tests show that no modification to the existing coal transport system and boiler equipment is necessary to achieve the outcome, provided that biomass percentage in the fuel mix is kept at 15%w or lower.
