The advantages of co-firong peat and wood in improving boiler operation and performance
Abstract
VTT Processes has studied co-firing of peat and wood based fuels inseveral national and international research projects. Utilisation of solidbiofuels sets new demands for fuel handling and feeding systems as well as forcombustion technologies. Wood fuels differ from peat in many properties;moisture content, heating value, energy density, particle size, ash contentand ash quality etc. All these factors effect greatly on fuel combustionbehaviour. One of the most important differences between wood fuels and peatis ash behaviour during combustion. Typically wood fuels contain higher amountof weak acid soluble alkaline metals, potassium and sodium, when compared topeat. These alkaline metals exist in different forms of compounds (sulphates,chlorides, nitrates, etc.) or they are attached directly to organic matter ingrowing plants. Easily soluble alkalies are released during combustion intogas phase and cause risk for boiler bed material agglomeration, fouling ofheat transfer surfaces and superheater corrosion. These phenomena have effecton power plant availability and production economics and thus they should becarefully recognised. Fouling inhibits heat transfer and reduces boilerefficiency, additionally; chlorine rich deposits induce hot corrosion of heattransfer surfaces. Effect of different fuels on deposition and corrosion havebeen studied by deposit and material testing probes, both in VTT's testfacilities and in power plant boilers. Studies show that with co-firing peatwith wood a great deal of benefits is achieved in controlling emissions andharmful forming of deposition. Depending on the boiler type, it is recommendedto combust 10 - 20 % of peat with wood fuels in order to reduce abovementioned operational problems. If wood fuels consist mainly of new treegrowth, like logging residue, it is favourable to use even higher share ofpeat, 30 - 40 %, as co-firing fuel.
