Hello! I'm from Luliang, Shanxi Province, and now the rural areas are mainly heated by boilers in winter. I would like to ask if there is any solar heating that can replace coal in our area.

Shandong CITIC Energy United Equipment Co., Ltd. is a leading enterprise specializing in the research, development and manufacturing of solar high temperature collector technology. Based on the values of "technological innovation and customer service", we provide the world with leading solar high-temperature collector technology solutions and advanced equipment.

The main business is "solar thermal power generation molten salt tower heat absorber; trough solar high temperature collector; CPC composite solar high temperature collector R & D, design, manufacture and sales; solar high temperature collector storage heating heating and cooling system R & D, design, manufacture and sales; solar high temperature thermal utilization of industrial energy-saving equipment and technology R & D. Design, manufacture and sales; solar high temperature thermal utilization of industrial energy-saving equipment technology, Design, manufacture and sales; solar high-temperature collector tube research and development, design, manufacture and sales; multi-energy high-temperature heat storage energy-saving system research and development, design, manufacture and sales; large-scale thermal engineering development; thermal engineering project management, as well as related design, consulting services, etc.".

At present, conventional coal-fired, oil, gas, electricity, biogas and other energy boilers with high operating costs and environmental pollution have gradually failed to meet the needs of most of the enterprises using boilers, so solar boilers with their energy-saving and environmentally friendly huge social and economic benefits are respected.

Solar boilers are relative to civil solar water heaters in the utilization of solar energy at high temperatures. United Nations Energy Agency research data show that "human consumption of fossil energy, more than 50% is to obtain industrial steam", the traditional industrial boilers (electric furnaces, oil furnaces, steam furnaces, etc.) if the "solar thermal energy" alternative, will save 50% of the traditional energy. The following is an example of the use of solar energy for medium and high temperature applications (100mW). Thus the use of solar energy in high temperature (100-300 degrees) is called "solar industrial boiler" or "solar boiler". Steaming, baking, drying, heating, heat preservation, fermentation, etc. is the basic function of industrial steam, most of the temperature of industrial steam in the 100-250 degrees between the temperature of ordinary dehydration drying temperature of about 80 degrees, such temperatures using the "solar thermal industrial boiler" can be successfully realized and It is relatively easy to commercialize and promote.

One, solar boiler diagram:

Two, solar boiler applications:

Solar high-temperature heat utilization system boiler can produce 100-300 degrees of high-temperature hot water, steam or hot air, can be widely used in daily drinking water, steam, heating, air conditioning, power generation, textiles, printing and dyeing, papermaking, rubber, seawater desalination, animal husbandry, food processing and other needs of hot water and hot steam. processing and other various production and living areas that need hot water and hot steam. In addition, the trough solar high-temperature boiler can also be combined with biogas, electricity, oil and other thermal technologies, is currently the focus of the combination of conventional energy and new energy applications.

Three, the technical barrier (collector tube)

Solar high-temperature collector tube is a low-carbon energy-saving, green and environmentally friendly strategic emerging products, it is a high-efficiency solar collector element, high heat collection efficiency, fast temperature rise, the highest collector temperature of up to 400 ℃. CITIC energy independent research and development, in the metal coating, increased transmission coating, glass metal sealing technology has the core of independent intellectual property rights, is expected to 16 years annual production capacity of 20,000 units. At present, it has three series of more than 20 specifications. The technology was first mastered in the hands of Germany Schott, Siemens and the United States. There are only a handful of domestic manufacturers with collector production technology, not to mention mass production.

CITIC Energy has passed the ISO9001 quality system certification and the European Union CE certification, high-temperature collector tubes, trough collectors have been exported to the Netherlands, Turkey, India, France, the Middle East and other countries, the feedback from the foreign market is good, and the products are running stably.

Four, the national policy for coal-fired boilers

At present, the vast majority of North China haze is serious, persistent, to the local people's lives and health bring great danger. Relevant experts pointed out that "coal to electricity" and "coal to gas" are only stopgap measures, the complete implementation of new energy alternatives is the ultimate solution to the problem. The government has issued a relevant policy, outlawed 10 tons of coal-fired, oil-fired boilers, to encourage and enforce the use of new energy policies, to the solar energy industry to bring benefits of high-temperature thermal utilization.

Comparison of ordinary electric boilers and solar boilers:

Fifth, the advantages of the solar boiler system:

1, a wide range of temperature regulation: solar collectors and heat accumulators *** with the role of the temperature of the oil can be freely adjusted between 80-320 ℃.

2, a wide range of applications: widely used in heating, air conditioning, building materials, textiles, printing and dyeing, papermaking, rubber, chemicals, food processing, pharmaceuticals, medical and other needs of the production of hot oil and steam and living areas.

3, high efficiency of heat collection: high-temperature heat collection equipment components using the international leading mirror glass made of concentrated light reflection device, stronger heat collection performance, more cost-effective. The collector efficiency is about 4 times of the common solar water heater.

4, short payback period: a one-time investment, long-term benefit, service life of up to 20 years or more; the shortest year can recover investment costs.

5, environmental protection and energy saving: no harm, no pollution, is the first choice of green environmental protection and energy saving.

6, the installation of a wide range: to minimize the occupation of land, equipment installation to support the use of the owner of the building roof space.

7, dual-energy security: 24 hours of solar energy can be used to continue to work, the external heat output, but also available gas, fuel oil as a supplementary energy to provide heat.

8, boiler heat transfer efficiency: steam generator unique heat transfer tube design, exothermic coefficient is large, is nearly 8 times that of the ordinary light tube, the effective heat transfer area is greater than the ordinary tube more than 50%.

9, high degree of automation: can automatically realize the temperature, pressure and flow rate of the precise adjustment and safety interlock control, so that the operation is more reliable.
