Cement plant adds coal heat backup in Arkansas

Ideal Cement in Arkansas will store coal as a standby heat source to replace natural gas during winter shortages. Plant manager Byron Thompson says gas use averages seven to eight million cubic feet daily, costing over a million dollars yearly, and the coal system, costing over two million, will enable steadier production and scheduling amid cold weather and gas cuts. A three year contract backs the move, with full transition planned by December or January.

Cement making process described with limestone slurry and kiln

The article explains cement production from limestone and limechalk ground with water to form a slurry. The slurry is balanced for calcium oxide aluminum oxide silicon and a touch of iron ore before feeding into a long rotating inclined kiln where it travels downward as heat from burning gas acts on it.

Cement production with lime slurry reduces sulfur emissions

At 2800 degrees Fahrenheit the slurry chemically converts and mixes natural gas and coal in a kiln. Gypsum is ground to a fine cement powder, then lime in the slurry absorbs sulfur from coal smoke. Thompson notes pollution controls and low sulfur coal will limit sulfur issues. By Jim Harris.
