DESIGNING OF SOLAR WATER BATH HEATER FOR GAS PRESSURE REDUCING STATION IN OF 150,000 Nm3/h CAPACITY IN ASSALUYEH REGION IN IRAN

This paper proposes the design of a solar water bath heater for
Central Power Plant in Assaluyeh region in south of Iran with
the latitude of 27 °N. This heater uses flat plate solar
collectors in an open circuit system. Solar intensity, absorbed
radiation and ambient temperature are the regional parameters
which are known to the designer. The temperature of the bath
of water which is the outlet collector temperature (70 °C)
belongs to the known parameters in the mentioned station.
Flow rate, heat loss factor, the inlet temperature of the
collector and the area which is the most important factor to
evaluate the economical issues of the system are calculated
with modeling the water bath with a shell and tube heat
exchanger. The solar water bath heater is then simulated with
TRNSYS software. The obtained results are in good
agreement with analytical solution based on Duffie and Beckman method.
