Comparison study of fuel characteristics of slow pyrolyzed chars with Neyveli lignite

ABSTRACT

As coals are fast depleting, suitable means of substituting coal need to be explored. In this work, a feasibility study of co-firing lignite with char was investigated. Some locally abundant biomass were slow pyrolyzed. The pyrolyzed chars were characterized and their fuel properties were compared with that of Neyveli lignite. The study indicated that the heating value of chars (except rice husk char) were higher than Neyveli lignite. The study also revealed that the properties of chars were on superior to Neyveli lignite and can be substituted to Neyveli lignite.
