Mejillones is located on the Pacific coast in the northern Chilean Atacama Desert. This is one of the driest places in the world, which hasn’t seen a drop of rain since hundreds of years. Therefore, all the water for E-CL’s (former EDELNOR) coal-fired power plant comes from a costly sea water desalination plant.
When Babcock & Wilcox Espanola, responsible for the boiler design of Unit #1 at Mejillones power plant, was informed about the availability of the well-proven dry MAC® (Magaldi Ash Cooler) technology, they changed the original decision for a submerged chain conveyor and adopted the MAC® system for the bottom ash handling.



Established in 1867, Babcock & Wilcox is a global leader in energy and environmental technologies and services for the power and industrial markets, with operations, subsidiaries and joint ventures worldwide, with approximately 6,000 employees, in addition to 2,500 joint venture employees all around the world. In 2004 Babcock & Wilcox was contracted by E-CL for the turn key Mejillones power plant project. E-CL is a Chilean utility company based in Santiago and formerly known as Edelnor.
E-CL is the main electric generator of the Northern Interconnected System (it represents around 50% of the interests of SING) and is the fourth at a national level for installed capacity, with 2.129 of gross power. The company's activities include the production, transportation and distribution of electric energy and natural gas; the purchase, sale and transportation of liquid, solid and gaseous fuels; and the provision of engineering consulting services. The company's products and services are mainly oriented towards the mining companies and other industries operating in the north of Chile. The company is a subsidiary of the French company ENGIE (former GDF Suez).



In the MAC® system the bottom ash is collected in a dry hopper, fitted with hydraulic bottom doors, and is continuously conveyed outwards by the MAC® extractor. The bottom ash is discharged from the MAC® extractor into a crushing process to reduce its size and then mechanically conveyed to a storage silo.
When after two years a second 150 MW class boiler was constructed by Ansaldo Caldaie, the order for a MAC® system was replicated, mainly for the following reasons:

Since 1998 the 2 MAC® systems have been working side by side and their performance has resulted in full Client satisfaction.
