Pulverized coal

Amec Foster Wheeler’s pulverized coal (PC) steam generators have a long history and reputation for high quality and a long reliable life. Since 1948, we have supplied 340 PC steam generators producing an equivalent of 111 GWe in electric power and co-generation plants, district heating plants and industrial facilities worldwide. Our utility steam generators have proven themselves with over 50 million hours of operation, up to 1,100 MWe in size, and have the capability of burning a wide range of coals from anthracite to subbituminous coals as well as petroleum coke.

Over our history, we have delivered 25 GWe of supercritical once-thru units (OTU) utilizing multi-pass, spiral and advanced BENSON Vertical Tube (BVT) technology. We were the first to offer BVT OTU technology and brings its high efficiency and safety feature to our utility clients. Similar to our subcritical drum units, BVT OTU features a natural circulation characteristic to cool overheated tubes under normal or upset scenarios, without relying on pumps, back-up systems or mechanical equipment.

Our unit’s feature many other time tested advanced design features like low NOx firing systems, MBF and ball mills, SCR systems, split and series back pass resulting in improved reliability, low emissions and peak plant performance.
