Steam curing of concrete is the method of curing the concrete elements in water vapor. This curing is performed either under atmospheric pressure or high-pressure steam. The steam curing method is preferred where there is a need for accelerated strength gain and the concrete requires additional heat to perform hydration. This is especially performed in […]
The cement clinker is ground with about 5% gypsum. Other materials like slag, fly ash, ash of coal etc may also be added in required proportion to get the final cement powder. The main fuel used for firing preheater cyclone and rotary kiln is coal. Therefore, coal plays an important role in the manufacturing process of cement. Based on the

Primarily for cement grinding plants in India, coal (generally of bituminous grade) is used in the slag-dryer. The wet slag arrives at the stack on wagons from some nearby steel plant, or it may be brought via a trolley-system (primitive mode). Bu...
(a) Variation in process heat for cement production with coal consumption and (b) variable steam turbine isentropic efficiency with the size. Fig. 4 shows the influence of cement plant capacity (5000–9000 TPD) and steam pressure (12–48 bar) on power cycle thermal efficiency, net power output, plant EUF and steam generation capacity.
Mar 01, 2016· According to the IEA, coal exports grew by 0.7% year-on-year to 1.38Bnt in 2014, including 1.05Bnt of steam coal and 322Mt of coking coal (Table 4). Coal exports have more than doubled since 2000. Steam coal exports fell by 1.72% to 1.05Bnt, while coking coal .
A method of manufacture of Portland cement clinker is described in a dry process that captures the carbon dioxide emitted from the calcination of carbonate minerals, principally limestone. The process uses an indirectly heated, counter-flow reactor to pre-heat and calcine the cement meal to produce a separate calcined meal and carbon dioxide gas stream, with external heat being provided by the ...
Steam coal - also known as thermal coal - is mainly used in power generation. Coking coal - also known as metallurgical coal - is mainly used in steel production. The biggest market for coal is Asia, which currently accounts for over 65% of global coal consumption; although China is responsible for a significant proportion of this.
Petroleum coke, also known as 'petcoke' is a by-product of the oil refining process. After fuel products and lubricating oils have been processed from crude oil, the excess is superheated through a process called 'coking'. This produces a stable, carbonaceous solid fuel that is often used in coal-fired power plants and cement kilns.
In 2019, about 539 million short tons (MMst) of coal were consumed in the United States. On an energy content basis, this amount was equal to about 11.3 quadrillion British thermal units (Btu) and to about 11% of total U.S. energy consumption.
Pulverised Coal Injection (PCI) technology involves injecting coal directly into the blast furnace to provide the carbon for iron-making – displacing some of the coke required for the process. A wider range of coals can be used in PCI, including steam coal which has a lower carbon content than coking coal.
