2. Intro
In CSP technology such as Trough, Compact Linear Fresnel Receiver,
Solar Tower, Solar Dish Stirling, etc required large area as shading effect. It
needs high insolation such as 1,000 W/m2 min. It is not suitable to operate
in humid and medium insolation such as 500 W/m2. As the structure too
long it needs good foundation in Soft-land area. It uses high power for
tracking as the system has no sound weight balanced. CSP had high thermal
losses due to long receiver tubes, long deliver fluid tubes, high temperature
thermal storage, and high working temperature. It required very good
thermal insulation. Once the structure to long it cannot prevented from
twisting so the structure will be large and heavy.
The turbine required high pressure, temperature, and dry steam quality.
Also generator required synchronous system when connected to grid. It is
not Easy to transport and assembly. As high technology the operation and
maintenance costs will be high. The material is not easy to find as the
system use high temperature. We expect the cost of CSP should below 90
THB/W, 3.0 US$/W, or 2.1 EURO/W when compare to solar cell. The Hybrid
Compact Linear Fresnel Reflector with Biomass and Induction Motor Farm
may solve these problems and make it possible for commercial.

Applications and Markets

10.  Solar Steam Generators (SSGs) use Concentrated Solar Power
(CSP) and Biomass or Biogas to drive steam engine or provide
process steam
 SSG could have dimension upto 365 m (1200’) long, 18 m
(60’) high, 36 m (120’) wide depend on power produced
 SSG can produce up to 10,000 kg/hr (22,000 lbs/hr) of
saturated or superheated steam
 Solar boiler, ASME S-Stamp qualify.
 SSG will not overheat, even with coincident failure of offsite
power (feed water and reflector drive) and backup power
(reflector drive) at solar noon on the summer solstice
 Durable designs of standard materials can be erected rapidly
and deployed at scale
 IBC/UBC structural design for Seismic Zone 4 and 145 km/hr
(90 mph) wind speed
