At present, the traditional coal-fired, oil-fired, gas-fired, electricity-fired, biogas and other energy boilers have high operating costs and pollute the environment, which has gradually failed to meet the needs of most enterprises using boilers. Therefore, solar boilers are highly praised by people for their great social and economic benefits of energy saving and environmental protection.
Compared with civil solar water heaters, solar boilers utilize solar energy at medium and high temperatures. According to the research data of the United Nations Energy Agency, "more than 50% of the fossil energy consumed by human beings is to obtain industrial steam". If the traditional industrial boilers (electric furnace, oil furnace, steam furnace, etc. ) replaced by "solar thermal energy", traditional energy will save 50%. Therefore, the medium and high temperature utilization of solar energy (100-300 degrees) is called "solar industrial boiler" or "solar boiler". Cooking, baking, drying, heating, heat preservation and fermentation are the basic functions of industrial steam. The temperature of industrial steam is mostly between 100-250 degrees, and the temperature of ordinary dehydration and drying is about 80 degrees. Such a temperature can be successfully achieved by using a "solar thermal industrial boiler" and is easy to be commercialized.

Second, the solar boiler application field:
The boiler of solar medium-high temperature heat utilization system can generate high-temperature hot water, steam or hot air with the temperature of 100-300 degrees, which can be widely used in daily drinking water, steam, heating, air conditioning, power generation, textile, printing and dyeing, paper making, rubber, seawater desalination, animal husbandry, food processing and other production and life fields requiring hot water and hot steam. In addition, the trough solar medium-high temperature boiler can also be combined with biogas, electricity, oil and other thermal technologies, which is the focus of the combination of conventional energy and new energy.
Third, technical barriers (collector tubes)
Solar high-temperature collector tube is a strategic emerging product with low carbon, energy saving and environmental protection. It has high heat collection efficiency and rapid temperature rise, and the highest heat collection temperature can reach 400℃. It is an efficient solar heat collection element. CITIC Energy has independently researched and developed metal coating, antireflection coating and glass-metal sealing technology, and has core independent intellectual property rights. It is estimated that 16 will produce 20,000 pieces. At present, it has more than 20 specifications in three series. This technology was first mastered by Schott, Siemens and the United States. There are only a handful of domestic manufacturers with the production technology of collector tubes, let alone mass production.
CITIC Energy Company has passed ISO900 1 quality system certification and EU CE certification. High-temperature collector tubes and trough collectors have been exported to Holland, Turkey, India, France, the Middle East and other countries, with good feedback from foreign markets and stable product operation.
Four, the national policy on coal-fired boilers
At present, the vast majority of smog in North China is serious and persistent, which brings great hidden dangers to the lives and health of local people. Relevant experts pointed out that "coal to electricity" and "coal to gas" are only expedient measures, and the complete implementation of new energy substitution is the ultimate way to solve the problem. The government has issued relevant policies to ban coal-fired and oil-fired boilers with a tonnage of less than 10, and to encourage and force the use of new energy, which will bring benefits to the solar energy high-temperature heat utilization industry.
Comparison between ordinary electric boiler and solar boiler;
Advantages of solar boiler system:
1, wide temperature adjustment range: solar collector and heat accumulator work together, and the oil temperature can be adjusted freely between 80-320℃.
2. Wide application range: widely used in heating, air conditioning, building materials, textiles, printing and dyeing, paper-making, rubber, chemical industry, food processing, pharmacy, medical treatment and other production and life fields that need hot oil and steam.
3. High heat collection efficiency: the parts of the medium and high temperature heat collection equipment adopt internationally advanced mirror glass, which has stronger heat collection performance and higher cost performance. The heat collection efficiency is about 4 times that of ordinary solar water heaters.
4. Short payback period: one-time investment, long-term benefit, and service life of more than 20 years; The shortest recoverable investment cost in the current year.
5, environmental protection and energy saving: pollution-free, pollution-free, is the first choice for environmental protection and energy saving.
6. Wide installation scope: minimize the land occupation and support the use of the roof space of the owner's building for equipment installation.
7. Double energy guarantee: solar energy can work continuously for 24 hours, and heat energy can be output. Natural gas and fuel oil can also be used as supplementary energy to provide heat.
8. High heat exchange efficiency of the boiler: the unique heat exchange tube design of the steam generator has a large heat release coefficient, which is nearly 8 times that of ordinary smooth tubes, and the effective heat exchange area is more than 50% of that of ordinary tubes.
9. High degree of automation: automatic accurate adjustment of temperature, pressure and flow and safety interlock control, and more reliable operation.
