- Biomass Co Burner For Cement Plant
Cement manufacturing is a hard-to-abate industrial sector that accounts for 5–8% of global anthropogenic emissions.Approximately 80–90% of these emissions occur during limestone calcination and fuel combustion processes.Decarbonising these two emission and energy-intensive processes requires a sustained and regenerative supply …

the kilns of our cement plants using secondary fuels. Until 2030, we aim to increase the share of alternative fuels to 43% of the fuel mix (2020: 25.7%), and to double the biomass rate from roughly 9% to 19%. This is one of the key levers to achieve our over-arching goal – to reduce our CO 2 emissions to under 500 kg per tonne of cementitious

Coal and coke, which were once the dominant fuels, have dropped from 74% to 57%. Waste fuel use was increased slightly from 5.5% to 6.8%, but alternative fuel use was increased from 2% to 8.3% in US cement plants. The alternative fuel use in 1996 represented just 2% of the energy consumption in cement plants, but by 2016, it was …

Biomass can also be co-fired, or burned with a fossil fuel. Biomass is most often co-fired in coal plants. Co-firing eliminates the need for new factories for processing biomass. Co-firing also eases the demand for coal. This reduces the amount of carbon dioxide and other greenhouse gases released by burning fossil fuels.
