Special equipment and facilities designed and manufactured for other special needs, etc. The boiler industry must adhere to a market-oriented strategy, rely heavily on technological progress and innovation. Guided by energy and environmental protection policies, it should adjust its corporate and product structures to produce and sell boilers that meet market demands, thereby securing a competitive position in the fierce market competition. In our country, the boiler industry is a sector in constant development, yet it faces various challenges as well as the companies operating within it. The boiler industry must adhere to a market-oriented strategy, rely heavily on technological progress and innovation. Guided by energy and environmental protection policies, it should adjust its corporate and product structures to produce and sell boilers that meet market demands, thereby securing a competitive position in the fierce market competition. 　　Recently, a boiler technology project carried out by the Zhuhai Testing Institute of the Guangdong Provincial Special Equipment Inspection Institute successfully passed the acceptance inspection by the **General Administration of Quality Supervision, Inspection and Quarantine. This project fills the technical gap in China regarding the rapid chemical testing of corrosion products in pressure-bearing special equipment. It is of great significance for guiding and assisting enterprises in adopting scientific and reasonable methods for equipment anti-corrosion and descaling, thereby enhancing the safety of pressure-bearing equipment and reducing corporate operating costs. 　　It is reported that this technology can effectively reduce equipment corrosion and the frequency of chemical cleaning of boilers, playing an important role in further enhancing equipment safety and saving business operating costs. Since the start of its research, Zhuhai Testing Institute has used this technology to assist three companies, both domestic and foreign, in carrying out equipment anti-corrosion and descaling tasks, helping them save nearly one million yuan in operating costs. 　　China’s boiler industry is neither an emerging nor a declining industry; it is an industry that will coexist with humanity forever. With the vigorous development of China’s national economy, the industrial boiler manufacturing industry has made significant progress in recent years. Its notable achievements include increasingly standardized industry standards, gradually improving technical levels, a growing variety of products, and a significant expansion in economic scale. Due to the growing market demand, the number of manufacturing enterprises has increased rapidly. By the end of 2008, there were 1,555 enterprises across the country that held boiler manufacturing licenses at various levels; of these, 1,205 had approvals from the General Administration of Quality Supervision, Inspection and Quarantine, while 350 had approvals from local provincial or municipal authorities. These enterprises are able to produce boilers of various pressure levels and capacities, thus meeting the needs of China’s current market. 　　From a long-term perspective, enterprises that are large power plants and thermal power station boilers with clear competitive advantages have better development prospects. At present, there are only a dozen or so manufacturers in the country specialized in boiler production, with their products mainly consisting of medium and high-pressure circulating fluidized bed boilers as well as chain grate boilers. From the perspective of demand, it is currently a good time to invest in power plant boiler products. The boiler industry is one of the major industries in China. Our country’s development in the field of boilers has also never ceased. Since the boiler industry is also a relatively popular sector worldwide, the improvement of boilers and the development of new types of boilers have become one of the key areas of research in various countries, and China is no exception. With the accession to the WTO, domestic power plant boiler products have developed rapidly, and competition in this sector is set to become increasingly fierce; competition among domestic companies is also inevitable. However, competitive market risks coexist with opportunities; companies that possess geographical advantages, technological advantages, and strong marketing networks will surely emerge victorious and take the lead in the subsequent market integration. 　　Considering the equipment and system conditions. If used in systems that operate continuously for long periods, a heat transfer oil boiler with high thermal stability must be selected ； When used in batch operation systems, the requirements regarding thermal stability can be relaxed somewhat; during periods when the equipment is not in use, it is possible to maintain the appropriate temperature by heating ； If used in equipment systems related to food processing, it is advisable to choose products that are non-toxic or have low toxicity and high safety, such as silicones and fluorine compounds ； If the same heat transfer oil boiler is used for heating and cooling processes, a heat transfer oil with a wide operating temperature range should be selected. 　　(II) Considering the usage conditions. When used in a liquid-phase system, it is generally advisable to choose a heat transfer oil boiler with a boiling point higher than the operating temperature, as a higher boiling point results in a lower vapor pressure during operation, which facilitates use ； If it is to be used under gas-phase conditions, it is necessary to choose a heat transfer oil with a vapor pressure within the range of 0.098~0.294 MPa (1~3 kgf/cm) at an appropriate operating temperature, such as a low-melting mixed heat transfer oil made of biphenyl and biphenyl ether. (III) Considerations from an economic perspective. It is necessary to have both good quality and low prices, to be cost-effective in order to reduce expenses. 　　(IV) Consideration from the perspective of operating temperature. Select an appropriate heat transfer oil furnace based on the operating temperature. When the operating temperature is between 350 and 400°C, a low-melting mixed heat transfer oil containing biphenyl and biphenyl ether should be used ； When the operating temperature is between 300 and 350°C, it is advisable to consider using alkylbenzene-type, dibenzyltoluene-type, or hydrogenated triphenyl-type heat transfer oils ； When the operating temperature is between 250 and 300°C, alkynyl naphthenes, benzyl toluene, and alkylbenzene-type heat transfer oils can be considered for selection ； If it is to be used at temperatures below 250°C, a mineral-based heat transfer oil boiler with a relatively lower price should be chosen. (V) Consider the conditions and requirements of the area where it will be used. If used in cold regions in the north, a heat transfer oil boiler with good flow properties at low temperatures should be chosen to facilitate the startup of the equipment ； In locations where strict regulations apply to hazardous materials, it is advisable to choose fluorine-based products that are safe and non-flammable. Pressure-bearing equipment such as boilers, containers, and pressure pipelines tends to develop scale deposits during operation; these deposits not only affect the efficiency of the equipment but also cause corrosion, creating safety hazards. In response to this phenomenon, the Zhuhai Testing Institute obtained approval from the General Administration of Quality Supervision, Inspection and Quarantine in October 2010 to launch a technical research project titled \"Study on the Application of Real-time Complexometric Colorimetry in the Corrosion Detection of Pressure Equipment.\" After more than 3 years of repeated experiments, a comprehensive database was established, and scientific and reasonable methods for equipment corrosion prevention, scale removal, and cleaning were found. 　　At the same time, **energy-saving boilers represent another opportunity for the development of this industry. In recent years, as there is an increasing call for low-carbon and environmentally friendly practices, people are paying more attention to the carbon emissions generated by their social activities. An economic model based on low energy consumption, low pollution, and low emissions represents another major advancement for human society, following agricultural and industrial civilizations. Therefore, concepts such as low-carbon lifestyles, low-carbon products and services have emerged one after another in various fields. Undoubtedly, this gave rise to the concept of energy-saving boilers in the boiler industry. Energy-saving boiler products are required to have a compact structure and small size for easy on-site installation, high efficiency and long service life, good sealing performance, and the ability to operate under positive pressure.
