Corrosivity of flue gases during co-firing Chinese biomass with coal at fluidised bed conditions

Corrosion in biomass combustion: A materials selection analysis and its interaction with corrosion mechanisms and mitigation strategies

“…(23) was also observed by other authors [94][95][96][97]. Zheng et al [98] have also confirmed the viability of this co-combustion strategy.…”

Biomass gasification or combustion for generating electricity in Spain: Review of its current situation according to the opinion of specialists in the field

“…Generally speaking, the combustion of coal and that of biomass are fairly similar. However, systems for the direct burning of biomass pose a series of problems: [30][31][32][33][34][68][69][70][71][72][73][74][75][76][77] • Fouling and corrosion in the combustion chamber caused by the alkaline nature of the biomass ash produced by the melting of combustion products at high temperatures. Slagging and fouling reduce the combustor's heat-transfer surfaces and cause problems of erosion and corrosion, thereby reducing the equipment's useful life.…”

Deposit chemistry and initial corrosion during biomass combustion – The influence of excess O2 and sulphate injection

“…In particular, this means avoiding the build-up of deposits rich in alkali chlorides. It has been demonstrated that deposit formation and superheater corrosion can be counteracted by co-combustion with sulphur-containing fuels or additives [14][15][16][17][18][19][20][21]. With a sufficient concentration of sulphur in the fuel, the alkali chloride can be converted into a less corrosive alkali sulphate (K 2 SO 4 ).…”

“…With a sufficient concentration of sulphur in the fuel, the alkali chloride can be converted into a less corrosive alkali sulphate (K 2 SO 4 ). Coal, peat and municipal sewage sludge are examples of fuels suitable for co-combustion with biomass [14][15][16]21], whereas elemental sulphur (S) and ammonium sulphate ((NH 4 ) 2 SO 4 , AS) are commonly used sulphur-based additives [14,[18][19][20].…”
