Abstract:

Present work provides the insight of dust particle effect on the overall efficiency of collectorreceiver tube water heating used in the power plant. Since the characterisation of dust particles deposited on collector plate and its controlled effect on plant efficiency has limitation for field scale study, we have proposed a new methodology to carry lab scale experimentation to characterise dust concentration followed by simulation to estimate the plant performance. Present study showed the effect of dust with respect to the clean surface efficiency. It should be noted that thermal efficiency of the system against clean surface is 20.59% and due to dust deposition efficiency of system reduced to 8.91 % at dust concentration 26.637 x 10-6gm/m2. Comparatively change in maximum thermal efficiency is reduced upto 56.726 %. Efficiency curve with dust concentration suggests that cleaning of the collector should be done in an optimised time interval rather than fixed time interval for better efficiency.
