With the development of economy and the expansion of city scale, the shortcomings of these traditional heating methods are more and more prominent, which can not meet the requirements of sustainable development. According to statistics, coal-fired heating has become the main culprit of air pollution in northern cities in winter. For example, in 1999, the terminal energy consumption of Beijing was 38.28 million tons of standard coal, including 2011 million tons of coal consumption, accounting for 53% of the terminal energy consumption, which is the main source of air pollution [1]. In order to avoid the low temperature corrosion of the rear heating surface, the exhaust gas temperature of the traditional coal-fired heating boiler is usually higher than 150 ℃, the steam boiler is even higher than 200 ℃, and the exhaust gas temperature of most gas-fired hot water boilers is between 140 ℃ - 200 ℃. High exhaust gas temperature not only consumes a lot of energy, but also increases the operating cost of the boiler [2,3]. Therefore, it is very practical and important to explore some clean, energy-saving and efficient heating technology for these areas, and gradually become a hot issue in engineering and academic circles.
