Short Review on the Origin and Countermeasure of Biomass

Kaolin(Al 2 O 3 ·2SiO 2) can decrease the amount of KCl released during co-combustion with biomass (Wei et al., 2005), and as a result, significantly reduce superheater deposits and slagging, consequently enhancing the operation of the biomass-fired boiler (Jensen et al., 1997; Davidsson et al., 2007, 2008).

Chlorine-induced superheater corrosion in boilers fired

Biofuel firing is an emerging technology in power production. Predominantly, biofuels are well suitable for utility and power boilers. The high concentrations of potassium and chlorine in some of the biofuels make their use rather devastating. Fouling is typically related to biofuel-firing, and all biofuels can be regarded as more or less corrosive. Chlorine-induced corrosion in biofuel-firing
