The advantages of the multi-duct dense-thin swirl pulverized coal burner are: First, the coal can be used instead of oil, then fuel cost is saved and operating cost is reduced greatly. Second, due to the special structure and reasonable air duct layout in the chamber, the pulverized coal can be stably and fully burned, and no ash residue is accumulated.

A schematic flow diagram is given in Fig II.19.4. Combustion of pulverised coal takes place at temperatures of about 1600 °C under a total pressure of about 15 bar. The produced flue gas is routed through a column of ceramic balls as a liquid-slag separation unit at an average temperature of 1450 °C.
Pulverized coal consists mostly of particles capable of passing through a 200-mesh screen, which corresponds to diameters of 74 microns and lower. For coals of high volatility and low ash content, the combustion characteristics are comparable to those of liquid fuel sprays discussed on page 320 .
The thermal cycle of a 750-MW size pulverized-coal—fired reference power plant is shown in the heat balance diagram of Figure 2-1. The pulverized-coal—fired steam generator provides main steam of 4133 psia/1112°F (285 bar/600°C) and reheat steam of 870 psia/1112°F (60 bar/600°C).

2019-1-1 Figure 1 is the schematic diagram of the New Experimental Equipment for Combustion of Pulverized Coal in Blast Furnace. As shown in the figure, the main device consists of high-pressure part and low-pressure part. Generally, the pressure of the high-pressure part was set as 5 atmospheres and the low-pressure part was 2 atmospheres.
2017-9-13 Pulverized Coal Injection. Pulverized Coal Injection (PCI) is a process that involves blowing large volumes of fine coal granules into the BF. This provides a supplemental carbon source to speed up the production of metallic iron, reducing the need for coke production. As a result energy use and emissions can be reduced.

Coal type determines the composition of coal and it reflects the degree of oxidation during coalification. Based on the van Krevelen diagram (van Krevelen, 1993), coal consists of three key material groups including vitrinite, liptinite and inertinite, which are composed of distinct constituents called macerals. Table 14.2 compares the key characteristics of coal macerals (van Krevelen, 1993).

Pulverised coal (PC) combustion is the most widely used technology for utility-scale power generation in the world. In PC boilers, coal is ground into fine particles (∼100 μm) and then injected with heated combustion air through a number of burners into the lower part of the furnace. Particles burn in suspension and release heat which is transferred into the steam cycle.
