Waste heat boiler refers to the use of various industrial processes in the waste gas, waste or waste liquid in the waste heat and the heat generated by the combustion of combustible substances to heat water to a certain temperature of the boiler, by the drum, movable hood, furnace mouth section flue, oblique1Section flue, inclined2Section flue, end1Section flue, end2Section flue, feeding pipe (blanking slip) groove, oxygen muzzle, nitrogen sealing device and nitrogen sealing plug, inlet hole, differential pressure taking device, flue support and hanger, etc. Its working principle is to transfer high-temperature exhaust gas or waste liquid to water or steam through a heat exchanger, thereby increasing the temperature of the water or steam, and then used for power generation or heating. Waste heat boiler has the advantages of energy saving, emission reduction and energy efficiency improvement, and is considered to be the fifth largest regular energy source after coal, oil, gas and water power.

Shangpu Consulting believes that the main factors affecting the development of China's waste heat boiler industry are as follows:

One is the policy factor. In recent years, a series of policies and measures to promote energy conservation, environmental protection and carbon neutrality have been introduced at the national level, providing a favorable policy environment for the waste heat boiler industry. For example, the Industrial Energy Efficiency Improvement Action PlanProposed the implementation of key areas of energy-saving transformation projects, including the promotion of steel and other high-energy-consuming industries residual energy recycling projects; "National Industrial Energy-saving Technology and Equipment recommend Catalog (2020）》Clarify the recommend application of residual energy recycling technology and equipment; Notice on Cleaning up and Regulating Charges for Urban Water Supply, Power Supply, Gas Supply and Heating Industry to Promote High Quality Development of the IndustryThe policy of reducing the cost of waste heat system is stipulated, and the guidance on accelerating the ultra-low emission transformation of the iron and steel industry calls for accelerating the ultra-low emission transformation of waste heat boilers in the iron and steel industry. In addition, provinces and cities have also issued corresponding local policies according to their own conditions, such as "Beijing2023The "14th Five-Year Plan for Industrial Energy Conservation and Emission Reduction in Jiangsu Province" proposes measures such as eliminating coal-fired boilers and promoting electric boilers. The 14th Five-Year Plan for Industrial Energy Conservation and Emission Reduction in Jiangsu Province proposes to implement industrial surplus energy recovery and utilization projects and promote the transformation and upgrading of waste heat boilers. The 14th Five-Year Plan for Industrial Energy Conservation and Emission Reduction in Guangdong Province proposes tasks such as accelerating the recovery and utilization of surplus energy in steel, nonferrous metals and improving the efficiency of waste heat boilers. The introduction of these policies will undoubtedly provide strong support for the development of the waste heat boiler industry.

The second is market factors. With the development of China's economy and society, the demand for energy in industrial production and urbanization construction is increasing, and at the same time, it also brings a large number of emissions of waste gas, waste water, waste residue and other pollutants, which has brought serious impact on the environment and people's life. Therefore, the use of waste heat generated in industrial processes for water heating or power generation can not only save energy, but also reduce pollutant emissions, which has important economic and social benefits. It is estimated that the average value of total recoverable waste heat resources in China is about13100 million tons of standard coal, of which high-temperature flue gas waste heat accounted for the highest proportion, reaching50%. These waste heat resources can be used for power generation, driving machinery, heating or cooling, etc., thus reducing the consumption of primary energy and reducing environmental pollution. According to data from the Champ Consulting Group,2022The cumulative installed capacity of waste heat power generation in China is about6000Ten thousand kilowatts. With the implementation of carbon neutrality targets and the improvement of energy conservation and environmental protection requirements, the utilization rate of waste heat resources and the installed capacity of gas and electricity will be greatly improved in the future, thus driving the demand for waste heat boilers to grow.

Three are technical factors. Technological innovation is an important driving force to promote the development of waste heat boiler industry. With the continuous improvement of the level of science and technology and the continuous changes in user needs, waste heat boiler products are constantly undergoing technical optimization and upgrading to adapt to new market needs and environmental standards. For example, in terms of product structure, due to the problems of low efficiency, large investment and high operating cost of traditional single-pressure cycle waste heat boilers, multi-pressure cycle waste heat boilers such as double-pressure cycle and three-pressure cycle have gradually become mainstream products; in terms of product parameters, due to the continuous improvement of users' requirements for product performance and quality, waste heat management equipment and clean energy solutions led by high-end technical parameters such as large-scale, high-efficiency, and supercritical are favored by the market; in terms of product application, due to the different characteristics and utilization methods of waste heat in different industries, waste heat boiler products are also constantly expanding New application fields and scenarios, such as waste heat power generation, waste heat heating, waste heat refrigeration, etc. in cement, steel, non-ferrous metals, chemical, glass, ceramics and other industries. These technological innovations not only improve the efficiency and performance of waste heat boilers, but also expand the market space and competitive advantage of waste heat boilers.

Four are competitive factors. After years of development, China's waste heat boiler industry has formed a group of leading enterprises with strong technical strength and market influence, represented by China Energy Conservation, China Metallurgical South, China Metallurgical North, China Metallurgical Jingcheng, China Metallurgical CCID, etc. At the same time, some small and medium-sized enterprises have participated in market competition, forming a relatively fierce competition pattern. According to data from the Champ Consulting Group,2022The market share of the top five enterprises in China's waste heat boiler market in19.8%China Metallurgical South16.5%MCC North14.2%, MCC Jingcheng12.6%, MCC Saidi10.4%, in total, occupied the market's73.5%It shows a high degree of concentration. These companies are competing fiercely in terms of product quality, technical level, service capabilities, and pricing strategies. At the same time, they are constantly innovating and expanding their markets to adapt to market changes and customer needs.

To sum up,2023China's waste heat boiler industry is in a stage of steady development, benefiting from the promotion of carbon neutral targets and the support of energy conservation and environmental protection policies, is expected to maintain steady growth, but also faces overcapacity, lack of technological innovation, environmental standards and other challenges. Therefore, it is suggested that waste heat boiler enterprises should strengthen technological innovation and product upgrading, improve product quality and efficiency, reduce product costs and emissions, expand new application fields and market space, increase product diversity and differentiation, and meet the individual needs of customers. It is necessary to strengthen cooperation and coordination with upstream and downstream enterprises to form industrial chain synergy and improve the overall competitiveness of the industry.
