摘要
东方锅炉厂制造的600MW超临界机组锅炉二次风道的直管段较短,采用均速管流量计进行风量测量时,达不道精度要求。对此,提出了进行风量修正等解决方法。实际应用表明,经过整定后的测量精度可达2%以内。
The straight section of secondary air duct for boiler of 600 MW supercritical unit manufactured by Dongfang Boiler Factory is shorter, at the time the measurement of air flow is being carried out by adopting velocityequalizing tube flowmeter, the required precision can’t be reached. For this, solving methods such as correction etc. have been put forward. The prectical application shows that the measurement precision can reach within 2% after setting.
