“…In the process of pulverized coal combustion, fuel-bound nitrogen accounts for 75 to 95% of the total NO x generated, while thermal-NO x and prompt-NO x account for the balance [15]. For coal, it is assumed that fuel-bound nitrogen is distributed between the volatiles and the char during coal combustion.…”

“…Table 2.1 summarizes the basic characteristics of the various types of stokers. Spreader stokers are the most commonly used type of stokers, because they can burn a wide range of coals, from bituminous to lignite, and they can accommodate a wide range of boiler sizes [21]. In these stokers, the coal is thrown and spread over the entire grate surface, by mechanical feeders (Figure 2.1a).…”

“…Efficient combustion, with no significant loss of unburned carbon, demands some care in matching burner configurations and furnace dimensions, as well as longer residence time than in a fuel-bed, since combustion of the char occurs in an atmosphere of decreasing oxygen concentration. The residence time in the furnace is typically 1-2 s, while the combustion temperature is 1300-1700 C. A large portion of the ash leaves the furnace as fly-ash, some of which deposits on the tubes, causing slagging and fouling, and the remaining falls to the bottom of the furnace and is removed [21,22,26].…”

“…Above this size, an uneconomically large furnace cross section would be needed for the required burners to be placed in the roof. Although downward firing is inherently stable, it has several disadvantages, such as a tendency toward burner overheating damage from slag falls and the difficulty of purging combustibles from the top of the furnace [3,21].…”

“…With higher ash contents, the losses caused by fusion and sensible heat of the slag generally outweigh any gains and a net decrease in efficiency results. Other disadvantages, compared with dry-bottom firing, are less flexibility of fuel selection, higher incidence of fouling and corrosion, higher levels of NO x formation, and lower average steam generator availability [3,21].…”

Energy drives human life and is crucial for continued human development. It is the convertible currency of technology. Without energy the whole fabric of society would crumble. Global demand for energy is rapidly increasing with increasing human population, urbanization, and modernization. This growth is projected to rise sharply over the coming years in developing countries. The world heavily relies on fossil fuels to meet its energy requirements -oil, gas, and coal are providing almost 80% of the global energy demands. Oil and natural gas prices are continuously rising, due to the rapid worldwide increase in their consumption. Coals, covering about 65% of the proven fossil fuel reserves and being widely distributed throughout the world, provide stability in price and availability and will therefore play a major role in the global energy system in the coming decades. Furthermore, given the energy crisis, the development and use of renewable energy sources is one of the key challenges in the shorter and medium term to substitute fossil fuels, to provide commercially attractive options for meeting specific energy service needs, and to mitigate greenhouse gas emissions. Biomass, including all kinds of materials that were directly or indirectly derived not too long ago from contemporary photosynthesis reactions, such as vegetable matter and its derivatives, is a widely dispersed, naturally occurring carbon resource with great energy potential. It is also considered as a CO 2 -neutral energy source. The simple act of burning biomass to obtain heat and often light is one of the oldest biomass conversion processes known to mankind.Thus, the study of coal and biomass combustion for power generation or heating processes is of extreme importance, if we are to conserve our sources of energy, while achieving the required environmental goal efficiently and reliably in a world of increasing population and energy needs. This chapter provides a survey of the technologies that are either available or are being developed to enable all solid fuels to be used cleanly and with greater amenity.

As the world is committed to reach carbon peak by 2030 and net zero by 2050, the use of coal as an energy source is facing unprecedented challenges. According to the International Energy Agency (IEA), global annual coal demand is estimated to drop from more than 5640 million tonnes of coal equivalent (Mtce) in 2021 to 540 Mtce in 2050 under the net zero emission scenario, mostly being replaced by renewable energy such as solar and wind. Therefore, the coal industry is vigorously seeking alternative applications to keep it thriving, and nanotechnology can be one of the contributors. Herein, the challenges to coal-based carbon nanomaterials syntheses are outlined, along with a path toward commercialization. Coal-based carbon nanomaterials can be promising contributors to the concept of clean coal conversion, initiating its migration from an energy source to a high-value-added carbon source.
