HBC made its first set of superhigh pressure parameter 670-680t/h boiler configured for 200MW turbine generator in 1960s, first case in China. After years of development and perfection, the boiler burning anthracite, meagre coal, bitumite, lignite, oil and gas is developed in succession, when the complete furnace series takes shape. It is exported to Pakistan. Ever since 1980s, under the guidance of design with high starting point and high standard, we properly absorbed the advanced points of the introduced technology, the design and manufacture of 670t/h boiler makes new progress. We have made 100-plus sets of superhigh pressure parameter 200MW boiler to date, who are in normal operation in 40-plus power plants home and abroad, receiving good remarks from the user.
