Compared with the traditional pulverized coal (PC) boiler, the circulating fluidized bed (CFB) boiler has many advantages such as high desulfurization efficiency when limestone powder is simply injected into the furnace, low NOx emission because of low combustion temperature, wide fuel adaptability, and excellent load adjustment ability (Huang et al., 2020; Yu Gu, 2020).

Figure 2. Schematic layout of a coalfired electrical generating station (Sear 2001). In the production of fly ash, coal is first pulverized in grinding mills before being blown with air into the burning zone of the boiler. In this zone the coal combusts producing heat with tempertures reaching approximately 1500°C (2700°F).

Abstract The share of coal generation in the global electricity production remains stable and prevails over other primary energy sources. A decrease in the coalfired power generation in some EU countries and the United States is balanced by its stable growth in Asia (China, India, Indonesia, South Korea) and Africa (South Africa). In 2021, global coal generation increased by 9% to a new all ...
