Description
There are many Biomass based power plants installed in the past 10 years in India for independent power production and export to grid. There are varieties of biomass being used in these plants. There are three types of biomass. First is the woody biomass, which covers all tress such juliflora, eucalyptus, casuarinas, cashew tree and many more forest trees & country trees. Secondly agro wastes such as rice husk, ground nut shell, bagasse, Coconut shell, coconut fronds, mustard stalk, mustard husk which are basically rejected material of our grain / food processing. Specifically grown grasses fall under third category. These biomasses have certain constituents which cause damage to boiler pressure parts by corrosion mechanism. I happened to study some biomass fired boilers which have suffered damage due to corrosion mechanism. In this paper the case studies are presented for readers understanding along with the fundamental mechanism behind this failure.
