HARBIN - China's first 350-megawatt double-rotor thermoelectric generator has completed 168 hours of test operations in northeast China. The generator was produced by Harbin Turbine Company, a branch of Harbin Electric Corporation, one of the largest manufacturers of power plant equipment in China, company sources said Sunday. It features stronger heating supply capacity and more efficient energy use for its double-rotor design, said Guo Pengfei, a researcher at Harbin Turbine. After being put into operation, it will be able to replace more than 200 coal-burning boilers. rubber wristbands in bulkcheap wristbandsrubber wristbandsblack rubber braceletsbat fidget spinnerhow to make rubber bracelets
SHIJIAZHUANG - The smog-prone northern Chinese province of Hebei has reported fairly good air quality for 66 percent of days since Oct. 1, the best record in five years, authorities said Tuesday.Hebei, which neighbors Beijing, is home to six of China's 10 most polluted cities, including the provincial capital Shijiazhuang, according to a Ministry of Environmental Protection report analyzing air quality in the first 10 months of this year.Levels of PM2.5, a type of airborne particle smaller than 2.5 microns in diameter, in Hebei have fallen almost 40 percent so far compared with the same period in 2013 to an average density of 64 micrograms per cubic meter, outstripping the 25-percent smog control target set in 2013, said Wang Xiaoli, a provincial environmental protection bureau official.Shijiazhuang has had only five days of heavy pollution since Oct. 1, down 38.6 percent year on year, and the city's hourly PM 2.5 density exceeded 300 per cubic meter only once, said Wang.In November, periods of heavy pollution in Hebei decreased by 1,278 hours, and its hourly peak PM2.5 density plunged 38.3 percent compared with the same period last year, said Wang.Under Chinese air quality standards, an air quality index (AQI) below 100 is defined as a good air quality day. An average daily AQI above 200 indicates heavy air pollution.Hebei recorded the worst air quality in 2013, with only 33 percent percent of days with good air quality, according to Wang.Overhauling polluting companies, dismantling coal-fired boilers, and controlling inferior coal have contributed to the decrease.Winter months are known to have the worst smog in north China with Hebei hit hard as the wind slows and residents turn on coal-fired furnaces for heating.
