Regulation of ash slagging behavior of palm oil decanter cake by alum sludge addition

Combustion of palm oil decanter cake (PODC) is a propitious alternative waste to energy means. However, the mono-combustion of PODC prompt severe ash slagging behavior which give rise to reduction in heat transfer and also shorten the lifespan of combustion reactors. In this study, alum sludge (AS)...

In this study, alum sludge (AS) was introduced at different proportion of 30, 50 and 70 to revamp the slagging characteristics of PODC during combustion.
