According to public data showed that in 2011, the industrial production of solar thermal vacuum tubes 8 million cigarettes, the solar energy water heater of vacuum tubes and flat 57.6 million square meters, a 17.6% increase over 2010, total quantities for 193.6 million square meters, the growth rate of 15.2%. The rate of growth of 30% compared with previous years, 2011 years has become the solar-thermal make use of the industry history of the slowest growth a year.
On the one hand, in the industry over the bad-mouthing argument; On the other hand, industrial prospects show good and make strong the solar-thermal enterprise hasten such as Wu of.
2011 this year, the solar-thermal first encounter late,glue gun part of a drought and waterlogging rain is exacerbated the terminal shipment of very difficult. Plus since this year, raw material costs, the human cost rise, to the solar-thermal industry has brought great pressure. Along with the home appliance pull effect to the country policy is slow, the solar energy rising faster no estimate of optimism. And in early 2011 to expose solar "quality door" event, is once again to the slowdown in the industry have a shadow.
According to public data showed that in 2011, glue stick the solar thermal utilization industrial output value is about 93.5 billion yuan, failed to achieve "yuan" goal. To this, the personage inside course of study expresses, the solar energy water heater industry sales YuCuo of the most fundamental reasons is still part of the rural market gradually saturated and city market promote blocked.
In rural market YuCuo and city market blocked, for the industrial market began to become a strength development strategy center. According to the national "1025" planning, low carbon energy conservation and emission reduction, and protect the environment is proposed in, new energy in seven big strategic new industry. The solar energy light heat utilization as the main force of the new energy, one of many industries have been listed as "1025" energy conservation and emission reduction in energy saving of the first application technology to the goal of industrial applications is expected to no less than 5000 square meters.
In the industrial application, the solar energy boiler, housetop type high temperature steam system, solar energy in the boiled water machine is very effect, more advanced application forms.
In the solar energy boiler, from linuo rhett solar energy boiler quite spectacular project, the project is relying on in its take up to five years, the investment of 120 million yuan of solar heat energy research and development of the application system technology, intended for coal, gas and oil burning boiler heat added do high efficiency, and to realize the papermaking, foodstuff, chemical eight major industrial production of thermal energy utilization, and tried to "industrial green power" in subsequent industry drive, the realization of the national industrial heat of 1.32 trillion total market development. It is reported, from linuo rhett solar energy boiler in CPC temperature project is with the boiler thermodynamic system integration collectors above, the enterprise unique in the entire glass vacuum coating tube temperature, CPC reflector technology, through focus absorb more solar thermal energy, 15 ℃ or so of cold water heated to 95 ℃, for 10 tons of coal boiler provide preheating hot water, again by boiler ℃ 95 ℃ to 150 hot water heating steam, the breakthrough in the domestic original collectors low temperature limit. The boiler system collection hot area of 5200 square meters, and the whole system can be saved each year BiaoMei 1156 tons, 3005 tons of carbon dioxide emissions.
In housetop type high temperature steam system of, can be used in industrial areas of housetop type high temperature steam system of solar energy this year in shandong sun valley startup success. The system adopts the latest himin solar energy research and development "linear Fresnel reflection" focusing collection hot technology, which can provide 100 ℃ ~ 250 ℃ industrial use hot, the technology has been successfully used for the high temperature heat power generation fields. According to introducing, this industrial steam system USES "linear Fresnel reflection" focusing collection hot technology, its core is the coating steel pipe and system integration technology related. Collectors can automatic focusing track the sun and collect solar, which causes the high temperature and high pressure steam, provide industrial use hot, the system can be installed in the factory building top, no extra occupied land resource, and at the same time investment and operation cost is low. Systems used in the subversion of the steel pipe coating temperature heat-resistant glass specification of these properties are low, issues in 300 ℃ ~ 350 ℃ in the air of the long-term stability can work, life is long, suitable for large-scale industrial application.
