Alternative Fuel Use in Cement Manufacturing 6 1.2 Emissions from cement production More than 50% of the total CO2 from cement production results from the chemical reaction that converts limestone into clinker, the active ingredient in cement.
Plastic Waste. Plastic waste is considered as one of the most available alternative fuel resources in cement industry due to their worldwide production and high calorific value, which ranges from 29 to 40 MJ/kg.
In recent years, the cement industry has been successful in reducing its operating costs and improving its carbon footprint (emissions per unit of output) by improving energy efficiency, increasing the use of alternative fuels,
Production of ordinary Portland cement — the most common type of cement — begins with the calcination of limestone, ... and most of the rest from burnt fuel. In total, ...
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 …
Thus, this review explores the potential of biomass as an alternative resource for clinker and fuel substitution, its role in Bioenergy Carbon Capture Utilisation or Storage, key aspects of the circular bioeconomy business model and identifies policy interventions for facilitating a sustainable transition from a fossil-fuel dominated cement ...
To varying degrees, cement substitutes work in two ways: • First, they hydrate and cure like portland cement. • Second they are "pozzolans," providing silica that reacts with hydrated lime, an unwanted by-product of concrete curing. Pulverised Fuel Ash (PFA), aka 'Fly ash' as a cement substitute.
2. Alternative fuel options for the cement industry Coal is the primary fuel burned in cement kiln s, however, the use alternative fuels in cement kilns is now common and increasi ng. The range of alternative fu els is extremely wide. They are usually available as gas, liquid and solid as shown in Table 1.
Historically, the primary fuel used in cement industry is coal. Recent increases of coal prices in the Indian market again made the cement industry vulnerable to fuel cost. Since then, petroleum coke has been successfully used as fuel and the use alternative fuels in cement kilns is now common and increasing.
With increased awareness of the large-scale CO 2 emissions from the cement industry, there has been growing focus on greenhouse gas reduction strategies. Among all these strategies, fuel substitution using biomass fuel is extensively used to achieve CO 2 zero-emission in cement production. Due to the avoidable high …
