Loesche has signed a contract with Doosan Heavy Industries & Construction for the supply of two Loesche coal mills type LM 43.4D for the coal-based integrated gasification combined cycle (IGCC) power plant (1 x 300 MW, net) to be built in Taean/South Korea. The IGCC technology is an extremely advanced and high-efficiency process whereby a synthetic gas consisting primarily of hydrogen and carbon monoxide is extracted from coal and used as fuel to generate electricity.
The scope of supply comprises the complete equipment from the raw coal feeding system to the product bag filter, including the Loesche grinding mills and Loesche hot gas generators, flaps, fans, electrical drives, and Loesche automation system. The throughput of the Loesche four roller grinding mill type LM 43.4D amounts to 95 t/h coal with additives (dry-base) based on the fineness of 10 % residue on 90 µm sieve. In this case the Loesche coal mill type LM 43.4D simultaneously grinds, dries, and classifies a mixture of coal and additives with more than 25 % moisture. The mill main drive power rating amounts to 1600 kW. The required process heat is provided by Loesche hot gas generators type LF 36 with a maximum heat capacity of 25 MW per each mill. The hot gas generator is operated with synthesis gas and natural gas.
Complete delivery FOB North-sea port is scheduled for May 2013 and commissioning is scheduled for the first half of 2014.
