Transformations of inorganic constituents leading to slagging and fouling in a cotton ginning residues fired combined heat and power plant

Objective



The use of agricultural residues (cotton ginning residues, wheat straw, wood chips, corn stacks) as a fuel in a CHP plant has the advantage of improving the energy efficiency of the plant while at the same time avoids the necessity of their disposal. The use, however, of such an unconventional fuel has the drawback of slagging and fouling in the combustor of the plant which leads to reduced operation efficiency and high maintenance costs. The main aims of the intended project are :
-To define the partitioning of inorganic constituents associated with raw fuel particles among product (including vapours, aerosols and residual char/ash particles) formed under conditions relevant to utility flames as a function of their specific (intrinsic and extrinsic) characteristics and the environment in which the transformation occurs and to finally characterize the resultant spectrum of products.
- To elucidate and quantify the fundamental processes involved in the transformation of inorganic constituents which will lead to minimum slagging and fouling predicament.
- To develop, based on the information acquired in the previous points, a tractable 'process' model capable of predicting the significant features of the transformation process, and most importantly, the nature and distribution of ash minerals.
- To design, develop, manufacture and test a CHP plant fired on cotton ginning residues.
