Abstract

Environmental constraints, emission regulations and market competition have led to efficient use of coal in power plants. Introduction of biomass in the feedstock of a coal-fired utility boiler is a cost-effective method to reduce CO2 emissions in energy generation, but it can affect combustion and heat transfer and enhance fouling inside the boiler. The necessity to monitor the operation and performance of a co-fired boiler online is obvious as it can lead to both financial and technical benefits. Development of online monitoring tools is a key activity in the supervision, diagnosis and control of the impact of ash fouling on the efficiency and operation of large co-fired boilers. These monitoring tools have to be based both on the design of new measurement practices and on the mathematical modelling of the physical processes, aiming at the accurate determination of the deposition rates. The Admoni project (Development of advanced monitoring methods to improve boiler availability and performance) aimed to study the effects of biomass co-firing on power plant availability by pilot and power plant measurements. For this purpose different types of fouling and corrosion probes were developed. The aim was also to develop online plant performance-based deposition formation monitoring methods and simulation software. This included both steady state and dynamic process simulations and boiler performance calculations which enable the quantification of the deposits and of the implications they have for boiler operation. Combustion kinetics and reactivity characteristics for selected project fuels were also determined
