Guide: Boiler manufacturing industry analysis report: The boiler is a kind of energy conversion equipment. The energy input to the boiler is in the form of chemical energy in the fuel, electric energy, and thermal energy of high-temperature flue gas. After the boiler is converted, it outputs steam with a certain amount of thermal energy. High temperature water or organic heat carrier. It is mostly used in thermal power stations, ships, locomotives and industrial and mining enterprises.
1. Basic overview analysis of the boiler industry: definition and working principle
The boiler is a kind of energy conversion equipment. The energy input to the boiler is in the form of chemical energy in the fuel, electric energy, and heat energy of high-temperature flue gas. After the boiler is converted, it outputs steam, high-temperature water or organic heat carrier with certain heat energy. . It is mostly used in thermal power stations, ships, locomotives and industrial and mining enterprises.
The main working principle of the boiler is a thermal equipment that uses the heat energy released after the combustion of fuel or waste heat from industrial production to transfer to the water in the container, so that the water reaches the required temperature or a certain pressure of steam.
The boiler is carried out in two parts of the "boiler" and "furnace" at the same time. After the water enters the boiler, the heating surface of the boiler in the steam-water system transfers the absorbed heat to the water, so that the water is heated to a certain temperature and pressure of hot water or steam, which is led out application.
In the combustion equipment part, the combustion of the fuel continuously releases heat, and the high-temperature flue gas generated by the combustion transfers the heat to the heating surface of the boiler through the heat transmission, and the temperature of itself is gradually reduced, and finally discharged by the chimney.
2. Subdivision of boiler products: various classification methods
In my country, there are many related classification methods for boiler products. The classification basis includes use, pressure, working fluid type and output state, body structure type, fuel or energy type, circulation method, etc. The more common one is to divide boiler products into four categories: power station boilers, industrial boilers, domestic boilers and special boilers according to their different uses.
3. Analysis of the industrial chain of the boiler industry: a wide range of downstream applications
The upstream of my country's boiler industry chain is related to the manufacturing of boiler equipment raw materials, mainly including steel and steel outsourcing parts, as well as accessories used for welding.
From the perspective of downstream applications, boilers are widely used in many industries in China. For example, power station boilers can be used for power generation in power plants; industrial boilers are mainly used for heating and hot water supply in various industrial production; domestic boilers can be used for various industries, mining, enterprises and institutions Units, hotels, service industries, etc. provide low-parameter steam or hot water;
There are also special boilers such as ship boilers and locomotive boilers that can be used to provide steam power for some transportation vehicles. On the whole, almost most important industries in the national economy are related to the boiler manufacturing industry.
4. Analysis of the development status of China's boiler industry: the output of industrial boilers is picking up, and the output of power station boilers continues to decline
Since 2015, my country's boiler environmental protection reform has continued to advance, the industrial boiler industry has entered a transition period, and my country's industrial boiler output has fluctuated and declined. In 2018, my country's industrial boiler output fell to 322,300 tons of evaporation, the lowest since 2011. Then in 2019, the industrial boiler industry gradually completed its transformation, and production began to gradually pick up.
According to the National Bureau of Statistics, my country’s industrial boiler output in 2019 was 393,900 tons of evaporative capacity. Although there is still a gap compared with the rapid growth period before 2015, it has shown signs of recovery, with a year-on-year increase of 22.22% compared to 2018.
Note: The production growth rate in 2013 was 19.43%.
From 2011 to 2019, my country's power station boiler output generally showed a downward trend. In 2019, my country's power station boiler output was 275,200 tons of evaporation, a year-on-year decrease of 19.74% compared with 2018. As of 2019, my country's power station boiler output has fallen by more than 10% for three consecutive years, and the overall performance is relatively sluggish.
5. Analysis of the development trend of China's boiler industry: environmental protection reform is imperative
With the increasing degree of environmental pollution, my country has increased its efforts to promote the green reform of the boiler manufacturing industry. During the special inspection of the national defense of the blue sky in 2018, coal-fired boilers were listed as the focus of inspection. During the inspection period from June 14th to July 7th, 2018, the inspection team inspected 300-500 coal-fired boiler companies that should be eliminated every day, and the inspection coverage was wide. Through environmental inspections, the replacement of small and medium-sized coal-fired boilers in my country has accelerated, and the future will focus on clean and efficient coal-fired boilers.
In addition to eliminating outdated and seriously polluting production capacity, my country has also implemented a number of policies to promote the new construction and environmental protection transformation of the boiler manufacturing industry. According to the "Clean Heating Plan for Northern Areas in Winter (2017-2021)", clean heating will replace 74 million tons of coal-fired boilers in 2019, and the northern clean heating rate will reach 70% in 2021, replacing 150 million tons of loose coal.
In addition, according to the 2018 "Opinions on Comprehensively Strengthening Ecological Environmental Protection and Resolutely Fighting Pollution Prevention and Control", it is clearly stated that we must vigorously promote the control of loose coal and the replacement of coal consumption reduction, and it is required that by 2020, 35 steam tons per hour in key areas should be basically eliminated. The following coal-fired boilers; promote clean and efficient coal-fired boilers.
