Estimation of gross calorific value based on coal analysis using regression and artificial neural networks. The multivariable regression studies have shown that the model (c) is the most suitable estimator of GCV. Running of the best arranged ANNs structures for the models (a) to (c) and assessment of errors have shown that...

cement industry. They found that the use of blended fuel is a key costeffective strategy for energy efficiency improvement and CO 2 emission reductions. Xiang Guo et al., [6] have performed experiment on combustion of waste tyre, high ash coal and tyrecoal blends with 10, 30 and 50% waste tyre
The difference between NCV and GCV is the latent heat of vaporisation of the water produced during combustion of the fuel: for coal and oil, the NCV is about 5 % less than the GCV for most natural and manufactured gas, the NCV is about 10 % less

India is the second largest producer of cement in the world. No wonder, India's cement industry is a vital part of its economy, providing employment to more than a million people, directly or indirectly. Ever since it was deregulated in 1982, the Indian cement industry has attracted huge investments, both from Indian as well as foreign investors.
A GCV margin 100–250 kcal/kg is normally provided in the power plant boiler design to take care of coal supply fluctuation. In India, the GCV margin used to be 400–750 kcal/kg, because all the existing plants were designed for a wider energy range to cater for the large proportion of unwashed coal and higher overall ash content value typical of Indian domestic coal.
