Abstract
Biomass utilisation by cofiring of straw in a pulverised coal fire
boiler is economically attractive compared to dedicated straw
fired plants. However, the high content of potassium and chloride
impedes utilisation of the fly ash, deactivates the de NOx
catalysts in the flue gas cleaning system and may also lead to
increased deposit formation. A pretreatment process is required to
solve the problems. In this paper two pretreatment processes are
considred, one based on straw wash and another based on pyrolysis
and char wash. To evaluate and compare the processes, laboratory
and technical invetsigations were performed. The economy of both
processes are favourable compared with seperate straw fired
boilers, however, the removal efficiency of potassium of the
pyrolysi based process is relatively low. At the present level of
invetsigations the straw wash process looks promising and
commercially viable.
