An important aspect of this program is the selection of suitable biomass feedstock from which biocoal will be produced, emphasizing potential problems of fouling and slagging in the boiler. We thoroughly tested seven different types of feedstock: Arundo Donax (AD), wheat waste, corn waste, woody hybrid poplar, and bark from hybrid poplar, woody pine, and bark from pine.

Boiler performance, emission and pulverizer self consumption were discussed. Considering all above aspects, we concluded that the most cost effective alternative is co-firing bio-coal with coal. AB - Co-firing biomass with coal seems a relatively low cost solution to reduce greenhouse gases (GHG) and is also an effective way of taking advantage of the high thermal efficiency of large …

Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.
