Coal gives way to tech­nol­ogy

China Daily - - CHINA -

In a bid to make its air cleaner, Beijing has been elim­i­nat­ing coal-fired boil­ers and up­grad­ing gas­fired boil­ers to make use of ni­tro­gen com­bus­tion tech­nol­ogy. The city has elim­i­nated 4,453 coal-fired boil­ers for heat­ing 13,259 met­ric tons of wa­ter per hour this year, the city’s en­vi­ron­men­tal pro­tec­tion bu­reau said. At the same time, im­prove­ments have been made to 7,000 gas boil­ers heat­ing 23,000 T/h, so less ni­tro­gen ox­ide will be pro­duced. As a re­sult, the city has man­aged to cut more than 10,000 tons of ni­tro­gen ox­ide, 3 mil­lion tons of coal, 5,500 tons of smoke and 6,600 tons of sul­fur diox­ide this year.
