Boilers that separate fly ash from bottom ash provide a better source of wood ash for use as fertilizer. This is because vaporization of metals in the combustion process (particularly at higher temperatures) is followed by condensation on cooler surfaces away from the heating zone, resulting in high heavy metal concentrations in fly ash ( Hakkila, 1989 ; see Table 4 ).
