由于测量的误差,锅炉常年在其试验效率下运行通常是不可能实现的。这往往是许多电力公司致力于提高仪表准确度,力图锅炉能在额定效率下连续运行的原因.大多数情况下,这些措施是和控制室内可控参数的屏幕显示相结合的(图1,略),后者告诉运行人员:关键的锅炉参数偏离标准工况有多远和由于热耗的增大使电厂费用增加,或每班资金的损失有多少. Due to the measurement error, it is usually impossible to run the boiler at its test efficiency all year long. This is often why many power companies are dedicated to improving the accuracy of their instruments and trying to keep their boilers running continuously at rated efficiency, most of the time they are combined with on-screen control of controllable indoor parameters (Figure 1 ), Which tells operators how far the critical boiler parameters deviate from the standard operating conditions and whether plant costs are increased due to increased heat consumption or how much money is lost per class.
