1. Introduction. Cement production contributes to around 18% and 5% of CO 2 emission in the industry sector and the globe, respectively [1].In the past two decades, there has been an increased interest in the cement industry toward substitution of fossil fuels with waste derived fuels, especially in cement calciners where around 3560% of the total fuel of the factory is fired [2].

Switching from China to India, the ten gasification reactors at the Reliance refineries at Jamnagar are designed to run on petcoke and for flexibility can also operate on a mixture of 35% coal and 65% petcoke. They are fed by five of the world's largest ASUs, each rated at a staggering 5250 tpd of oxygen.

Coal mining produces significant amounts of solid waste. The reason for large discrepancies between boilers and cement plants the lack of data on solid waste produced in hard coal mining. Hard coal is used in cement plants along with petcoke, whereas the boiler uses generic coal for which solid waste data are available.

Petcoke becomes a key raw material with a fewer substitutes especially for clinker production. Thus petcoke is proving to be economical for the industry, followed by coal is the preferred source of fuel for power plants. Coal on the other hand is used as fuel for power plants by the captive power producers in the cement industry.

Energy Consumption. The average energy demand for producing 1 ton of cement is around GJ of thermal energy, which equates to 120 kg of coal with a calorific value of MJ/kg and roughly 110 kW hr/t of electrical energy [10, 22, 23].Burning operations employ the majority of the thermal energy, whereas cement grinding utilizes the electrical energy [24, 25].

Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...

Grinding of clinker consumes power in the range of kWh/ton of clinker produced. These and other pyroprocessing parameters make cement production costly. The pyroprocessing process in kilns and the grinding technologies therefore have to be optimized for best processing. This paper discusses the cement manufacturing and grinding processes.
