Pulverized Coal Injection in a Blast Furnace IspatGuru

10/05/2013 Pulverized coal injection (PCI) is a process which involves injecting large volumes of fine coal particles into the raceway of the blast furnace (BF). Pulverized coal is an important auxiliary fuel used in the BF ironmaking. PCI provides auxiliary fuel for partial coke replacement and has proven both economically and environmentally favourable.

Pulverized coal injection method Wikipedia

Pulverized coal injection was developed in the 19th century, but was not implemented industrially until the 1970s. Rises in the cost of coke due to increased global demand and thus more competition for the resource have made this method attractive to the iron-producing industries and increased its value. The PCI method is based on the simple concept of primary air (termed the "conveying gas") carrying pulverized coal which injected through a lance to the tuyere(mid-bottom inlet of a blast furnace), then mi

AND PULVERIZED COAL FURNACE

Pulverized coal furnaces are usually convertible to firing with oil or gas. Units near oil refineries may utilize fluid coke. Pulverized coal firing removes a limitation on the amount of fuel that can reburned in a boiler (with stoker firing there is a definite limit).

Basic Co-Firing Characteristics of Ammonia with Pulverized

14/12/2018 In this study, basic co-firing characteristics of pulverized coal and ammonia were investigated using a bench-scale single burner test furnace. A schematic diagram of the single burner test furnace is shown in Fig. 1. The rated thermal input of the furnace is 760 kW, which corresponds to approximately 100 kg/h of coal for common bituminous coals.

Pulverized Coal Combustion of Nitrogen Free Blast Furnace

The influence of low x o /x c on coal combustion performance under nitrogen free blast furnace condition was researched through the self-developed pulverized coal burning device. The results show that the coal combustion rate reduces with x o /x c decreasing, and the combustion rate of bituminous coal is higher than that of anthracite. The coal combustion rate ascends with the rise of volatile
