However, improvements can still be made to further increase the thermal efficiency of some kilns converting the preheater to precalciner kilns and recovering heat from the cooler, thus generating up to 20 % of electricity needs for the cement plant [4]. CEMBUREAU is targeting a 4 % improvement in thermal efficiency by 2030, moving to 14 % in 2050.

Oxy-fuel combustion technology for cement production – State of …

In cement kilns heat transfer is mainly dominated by radiation. Moreover, radiation heat transfer is determined by particle and gas radiation. In oxy-fuel combustion, higher concentrations of CO 2 and H 2 O in combustion gases are expected. In comparison to N 2, these gases are not transparent to radiation. This difference has a high impact on ...

Mercury Pollution from Cement Kilns Double Previous Estimates

Just over 150 cement kilns operate in the United States and, each year, they "cook" thousands of tons of rock — primarily limestone — at more than 2,600 degrees Fahrenheit. To fuel this cooking process, cement kilns burn primarily coal. Both the rock and the coal contain mercury, a highly volatile metal that evaporates at room temperature.
