HBC, in 2004, introduced the design and making technology for Japan Mitsubishi ultra-supercritical 600MW-1000MW boiler, and the first unit of 1000MW is in operation in 2006. the operation of such boiler marks the technical level for thermal power BTG has reached the most advance level in the world. HBC designed and made the first 600MW ultra supercritical boiler in China in the afterward. We, in 2004, introduced the design and making technology for Japan Mitsubishi ultra-supercritical 600MW-1000MW boiler. HBC has signed the supply contract for over 50 such boilers at present, among which 15 sets are in commercial operation. HBC first ultra-supercritical boiler used in Yuhuan Power Plant 1000MW ultra supercritical unit (first ultra-supercritical boiler in China as well) was awarded Top Prize for National Science Progress in 2007.
