How this would fit with any kiln electrification plans is unknown. However, one attraction of moving to an electrical kiln, for all of the projects above, is to cut out the 40 – 50% of a cement plant's CO 2 emissions that arise from the fuel that is burnt. Taking a kiln electric also makes CO 2 capture easier.

Mexico: Holcim Mexico has concluded a deal to set up a trial of hydrogen injection in kilns at one or more of its seven cement plants in Mexico. The producer says that the technology will optimise combustion processes and facilitate the increased substitution of alternative fuel.
The NSP is suited for medium- or large-scale cement plants that are being either expanded or rebuilt. Smaller cement plants have traditionally used the earthen vertical kiln, but this method should be replaced. For this measure, the energy saving and emission reduction have been documented to be 2.4 GJ/t and 62 kgCO 2 /t. 4. Cement …

In early February 2021 the Mexico-based producer said it was spending US$15m to restart a 1Mt/yr kiln at its CPN cement plant in Hermosillo, Sonora. The unit is over 250km from the US border but Cemex said it was making the investment to cope with cement shortages and project delays in California, Arizona and Nevada.
Once operational, the recommissioned kiln is expected to provide nearly 800,000 additional metric tons of cement for customers across Arizona, California and Nevada. CEMEX will invest US$29 million to bring on the second kiln in its Sonora, …
CEMEX is optimizing its supply chain to meet shortages experienced throughout the western United States. The plan includes investing around $15 million to …
This example shows the resultant savings for only one relatively small kiln. There have been reports where up to a million dollars annually have been saved on larger kilns after extensive modifications were made on existing systems.Naturally, in such plants energy conservation was a high priority item and a well-defined conservation program must …
By injecting hydrogen into its cement kilns as a catalyst, CEMEX may optimize the combustion process and increase its use of alternative fuels, decreasing its …

However, some cement plants in the past have suffered fires or explosions in cement kiln air pollution control devices (APCDs). Dobson (1974), with Factory Mutual Research, stated that between 1971 and the date of the article (1974) damage had been reported to nine ESPs in cement plants insured by Factory Mutual.
Its U.S. network includes 10 cement plants, close to 50 strategically located cement terminals, nearly 50 aggregate quarries and more than 280 ready-mix concrete plants. CEMEX USA has been repeatedly recognized for its efforts in sustainability and energy management, including earning U.S. EPA ENERGY STAR ® Partner of the Year in …
Just as a heart must never stop beating, so a rotary kiln must never stop turning. Which is why our kilns – whether the two-pier Pyrorapid ® or a classic three-pier kiln – are engineered to keep rotating, even in the …
Cement production has been one of the most energy intensive industries in the world. In order to produce clinker, rotary kilns are widely used in cement plants. This paper deals with the energy audit analysis of a dry type rotary kiln system working in a cement plant in Turkey. The kiln has a capacity of 600 ton-clinker per day.

TXI's cement capacity will increase by a further 1.4Mt/yr to approximately 7.1Mt/yr in the early part of 2013, when the company commissions kiln 2 at its Hunter cement plant. "We remain on track to complete the construction on the expansion of our central Texas cement plant this fall," said company CEO Mel Brekhus.
The energy efficiency of cement plants strongly depends on the type of kiln used for clinkerisation [49]. Cement kilns have evolved from long wet kilns to state-of-the-art dry kilns with a calciner, a 6-stage preheater and a high-efficiency cooler. Biomass can be utilised as a fuel in both old wet kilns and modern dry kilns.
