The project in the treasure of the sea, the original building roof mounted solar collector, solar thermal power system with industrial development, utilization of solar assisted heating boiler water supply way, using solar collector to the boiler water softening temperature to 70 ℃, then the high temperature water into the boiler, the coal for the two time heating, heating to saturated steam after meet the needs of enterprise production. Project scale: the collector area of 2830 square meters, the project annual daily average 70 ℃ hot water 90 tons, saving 464 tons of standard coal, 1160 tons of carbon dioxide emissions, 8.4 tons of sulfur dioxide, and has good environmental, economic and social benefits, and won the 2012 major section of the Shandong Province Technology industrialization reward fund 1000000 yuan.
