High performance and low emissions - optimisation of multifuel-based bioenergy production
Abstract
There is a growing international interest in utilising renewable fuels, also in multifuel applications. Main reasons for this are the objective to reduce CO<sub>2 </sub>emissions and meet emission limits for NO<sub>x</sub> and SO<sub>2</sub>. On one handcofiring, defined as simultaneous combustion of different fuels in the sameboiler, provides an alternative to achieve emission reductions. This is notonly accomplished by replacing fossil fuel with biomass, but also as a resultof the interaction of fuel reactants of different origin (e.g. biomass vs.coal). On the other hand, utilisation of solid biofuels and wastes sets newdemands for process control and boiler design, as well as for combustiontechnologies, fuel blend control and fuel handling systems. In the case ofwood-based fuels this is because of their high reactivity, high moisturecontent and combustion residues' high alkaline metal content.Combustion and cofiring properties of fuels have been studied both in VTTProcesses' test facilities and in industrial-scale power plant boilers. Theformation of alkaline and chlorine compounds in biomass combustion and theireffect on boiler fouling and corrosion have been monitored by temperaturecontrolled deposit formation and material monitoring probes. Deposit formationmonitoring at full-scale boilers provides unique information on the rate ofdeposit formation, the effect of sootblowing and consequent changes in heattransfer. Additionally, the data from deposit formation monitoring has beenshown to correlate with boiler performance, which gives basis for studying theinterrelation of: fuel blend characteristics - deposit formation - boilerperformance.If biomass fuels are blended with coal or peat, following implications may beexpected: increased rate of deposit formation, shorter sootblowing interval,cleaning of heat transfer surfaces in revisions may be required, bed materialagglomeration (in fluidised beds), increased risk of corrosion, higherin-house power consumption, higher flue gas temperature. These factors affectoperating and maintenance costs, but their effect can be reduced or evenavoided with appropriate fuel blend control. By the aid of the aforementionedmeans, optimum share of biomass fuel in different fuel blends can be defined.
