Typically, RDF can replace up to 15-20% of primary fossil fuels used in cement plants. However, the current thermal substitution rate (TSR) or the rate of co-processing wastes in India rangesConsidering the overall fuel consumption for heating kilns, the cement industry primarily relies on coal, which results in large amounts of carbon dioxide (CO 2), sulfur dioxide (SO2), and nitrogen dioxide (NO2) emissions. Carbon emissions from cement industries of Pakistan has increased 17 % from 2015 to 2020 (Rasheed et al., 2022).Circular economy and its implementation in cement industry:

Deep Decarbonization of the Cement Sector: A Prospective Environmental

One of the top carbon dioxide (CO 2) sources is the production of cement, an important binding material around the world.Within this hard-to-abate sector, CO 2 is mainly released by the reactions involved in clinker production, whereas fuel combustion, generally coal, petcoke, and natural gas, entails the remnant CO 2 direct Coal use in the cement industry. Coal is used as an energy source in cement production, which is a critical commodity for the construction industry. Over 3.3 billion tonnes of cement were consumed globally in 2010. Cement is made from a mixture of calcium carbonate, silica, iron oxide and alumina in a high-temperature kiln that is often Industrial uses of coal ScienceDirect

Control of Precalciner Temperature in the Cement Industry:

As the most critical equipment in the pre-calcination process of dry cement production, the temperature of the precalciner is an essential factor affecting the quality of cement. However, the cement calcination system is time-delayed, nonlinear, and multi-disturbance, which makes it difficult to predict and control the precalciner temperature. In The cement price increase, in turn, is driven by internal abatement costs, i.e., investments in BAT and CCS kiln systems (C1–C3), and the purchasing of emissions allowances at 40 €/tCO2 (a–c(PDF) Managing the costs of CO 2 abatement in the cement industry

Coal and its application in the cement production process

A kiln for cement production typically uses coal as a fuel to heat a mixture of raw materials at 1450°C, transforming the chemical and physical components to form a new substance called a clinker a gray pebble-like material consisting of special compounds that give cement its characteristic binding properties.2. Alternative fuel options for the cement industry. Coal is the primary fuel burned in cement kilns, however, the use alternative fuels in cement kilns is now common and increasing. The range of alternative fuels is extremely wide. They are usually available as gas, liquid and solid as shown in Table 1.Alternative Fuels in Cement Manufacturing IntechOpen

A critical review on energy use and savings in the cement industries

Grinding is a highly energy intensive process in the cement industry. Approximately 60–70% of the total electrical energy used in a cement plant is utilized for the grinding of raw materials, coal and clinker [63]. The electrical energy consumed in cement production is approximately 110 kWh/tonne.Technology for alternative fuel firing. Use of low-grade alternative fuels such as waste coal, tyres, sewage sludge, and biomass fuels (such as wood products, agricultural waste, etc.) in pre-calciners is a feasible option since combustion in pre-calciner takes place at a lower temperature. India is the second largest cement producer in theTechnology for alternative fuel firing Indian Cement Review

Energy and Economic Comparison of Different Fuels in Cement

Energy cost contributes to about 40–50% of cement production cost in Nigeria depending on the production process and type of cement with 1 tonne of cement requiring 60–130 kg of fuel or its equivalent and about 105 kWh of electricity [ 3 ]. Fossil fuels like coal, pet coke, fuel oil, and gas are the primary fuels used in the cement kilns.Coal India Limited (CIL) and Singareni Collieries Company Limited (SCCL) are the prime suppliers of domestic coal. While almost 65% of the total domestic coal is sourced from CIL, the remaining 35% is Cement Industry: Energy Requirements CMA India

Fuels in the cement industry INFINITY FOR CEMENT EQUIPMENT

Coal used in the cement industry should comply with the following requirements: LHV 6500- 7000 kcal/kg. Ash: 12-15%. Volatile matter: 18-22 0/o Moisture up to 12 0/o, as delivered. In some East European countries brown coal for clinker burning is frequently employed. This coal has the following properties: LHV = 4800 kcal/kgFor Indian cement industries, coal fulfils ninety-four per cent of the thermal energy demand. In contrast, the remaining need is fulfilled by fuel oil and high-speed diesel oil. The cement industry in India does not have sufficient natural gas available for fulfilling the thermal energy requirement (Karwa et al., 1998).Review on energy conservation and emission reduction
