الملخص الإنجليزي

The present work deals with a concentrating solar system (central receiver tower) to produce hot water and steam from solar energy.

Hot water is used in a feed water heater for South Baghdad Electrical Steam Power Plant.

The central receiver system consists of 150 mirrors fixed upon 75 tracking heliostats that arrangement to focus the solar radiation on central receiver tank.

The piping systems were used to carry the hot water from central receiver tank.

In this project, the dimension of central receiver cylindrical tank was 0.5m diameter and 1m height filled with 157 liter of water.

The experimental work was done in one year period from June 2015 to May 2016.

Examining the phase of the outlet working fluid (water) from the tank showed that it is steam in (July and August) and hot water during the rest of the year.

Result showed that the maximum contribution (f-factor) is 1.86% and the average contribution during the whole year is 1.03%.

Result also showed that the increase in average tank temperature during each month has the same trend.

The temperatures have the higher values during summer season (June – August) and lower values during winter season (December – February).

The theoretical calculations showed that the temperature of receiver tank is proportional to the number of heliostats.

The comparison between experimental and theoretical results showed good agreement and can be used as an initial estimate tool in the design of central receiver system.
