Scale-Up Strategies for Solar-Thermal Boiler Feed-Water Prehearing Systems

Boilers and hot water generators are major consumers of energy in all sectors. The potential for efficiency improvement and energy conservation is significant, especially in small and medium enterprises (SMEs). The renewable energy industry has long proposed the integration of solar-thermal technology as one important measure for efficiency improvement. However, while solar-thermal hot water systems have made significant inroads in some markets, their use in industrial and commercial settings has been minimal. As a part of IIEC’s Solar-Thermal Market Facilitation Initiative (STMFI), ground-breaking projects in India and Thailand are set up to demonstrate commercial applications of solar-thermal system integration for boiler feed-water pre-heating. The next stage of STMFI is the scale-up of this renewable energy based efficiency measure around the world.
