Lazard does not explicitly define its ranges with and without CCS; thus, the high end of their pulverized coal and IGCC ranges and the low end of their IGCC-CCS range are assumed to be the middle of the full reported range. All sources have been normalized to the same dollar year. Costs vary due to differences in system design (e.g., coal rank), methodology, and plant cost definitions.
A coal-fired thermal power station is a power plant in which the prime mover is steam driven. Water is heated, turns into steam, and spins a steam turbine, which drives an electrical generator, as schematically shown in Fig. 1.9.After it passes through the turbine (one to three stage), the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnacefor the combustion of solid fuels. Coal is ground to the size of a fine grain into the boiler, mixed with air and bur
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.

Pulverized coal injection method. 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.

Coal transportation costs can be significant. Once coal is mined, it must be transported to consumers. Transportation costs add to the delivered price of coal. In some cases, such as in long-distance shipments of Wyoming coal to power plants in the East, transportation costs are more than the price of coal at the mine.
The second three inputs characterize the capture plant: • Incremental capital cost, in $/kg of CO 2 processed per hour; • Incremental cost of electricity due to operation and maintenance, in mills/kg of CO 2 processed; • Energy requirements of the capture process, in kWh/kg of CO 2 processed. The capture efficiency is usually about 90% in the studies reviewed.
The capital cost of the pulverized coal firing system is. considerably high as it requires many additional auxiliary. equipment. Its operation cost is also high compared to stoke firing.

A 2000 MW power station could be handling coal in the range of 1600 tons/hr or around 12 million tons of coal annually. A single 500 MW unit consumes in the range of 400 tons/hr of coal. The coal input to the boiler of the power plant passes through three different phases before combustion in the boiler.
Coal transportation costs can be significant. Once coal is mined, it must be transported to consumers. Transportation costs add to the delivered price of coal. In some cases, such as in long-distance shipments of Wyoming coal to power plants in the East, transportation costs are more than the price of coal at the mine.
Petra Nova’s post-combustion CO2 capture system began operations in January 2017. The 240-megawatt (MW) carbon capture system that was added to Unit 8 (654 MW capacity) of the existing W.A. Parish pulverized coal-fired generating plant receives about 37% of Unit 8’s emissions, which are diverted through a flue gas slipstream.
cycle is the same as for pulverized coal plants, efficiencies are in the same range as the pulverized coal plants. As with the pulverized coal plants, this configuration may be pressurized to increase efficiency, but the gains come at increased capital and operating costs. Figure 2.
