As a major solid waste in coalfired power plants, circulating fluidized bed fly ash (CFBFA) has a high content of SO 3 and fCaO, leading to a lack of avenues for its resource the characteristic of it, this study combined it with ground granulated blast furnace slag (GGBFS) to produce an ecofriendly cementitious material (CGL) without cement.
Coal based power generation. The energy conversion efficiency of the coalbased power generation process is represented by the following formula: (8) η U 1 = P G × ( 1 − A P R) / C C P × 100 % where PG is Power generation of coal (tce), APR is auxiliary power ratio (%), and CCP is coal Consumption for power (tce).
Pulverised coal injection (PCI) is used in ironmaking to replace expensive and energy intensive coke with coal, reducing overall costs and greenhouse gas emissions. As the coke making process removes some of the sulphur present in coal, the utilisation of PCI results in the admission of greater levels of sulphur into the blast furnace.

The utilization of coal nowadays requires both indepth research and extensive exploration, balanced with environmental concerns. An equally essential step before its utilization is the processing of coal. The heterogeneous composition of the complex organic structures and associated minerals of coal makes efficient separation a challenge ...

He assumed a "waterconscious" future in ...
Low energy efficiency and high emissions of coal utilization. As a highcarbon energy source, coal will inevitably bring about carbon emissions during the process of utilization. China's CO 2 emissions per unit of GDP are much higher than those of developed countries, and its total emissions now rank first in the world. The energy ...
