Prospects of Solar Fuel Technologies in Uzbekistan
Abstract
A double-loop solar fuel boiler installation scheme is studied. The following problems are considered: - economic optimization of a heating surface of intermediate thermal exchangers in view of thermal efficiency of the solar water heating system; - determination of the hot water load replacement factor of the solar water heating system; - calculation of the specific area of solar collector’s surface of the double-loop solar-fuel boilerhouses. One of real ways of energy saving and reduction of emission of harmful products on combustion of organic fuel for municipal’s heat supply systems is transition existing low-power and ineffective boiler-houses to solar-fuel technology. In Uzbekistan it is developed and successfully introduced as combined scheme of heating low-power (up to a3y5 MW) boilers and double-loop solar attachments , consisting of flat solar water-heating collectors and high-speed heat exchangers, for preheating feeding water (a up to 40y50 ɨɋ ) (fig.1).
