Through testing

the energy consumption indicators of supercritical circulating fluidized bed(CFB) boiler units

the heat losses of the boiler and the structure distribution of the service power rate for the supercritical CFB units were analyzed

and the optimization direction for energy saving of supercritical CFB boilers was proposed. Combined with the applications and operation practices of the low energy consumption technology for large scale CFB boilers in service

the technical measures of the low energy consumption technology for supercritical CFB boilers were researched and proposed

from the aspects of improving the boiler efficiency

reducing the energy consumption of air fan

and low-energy-consuming pollutants control. Moreover

related technical transformation was carried out on a supercritical CFB boiler

and the changes in energy consumption indicators before and after the transformation were analyzed. The result shows that

after the transformation

the energy saving effect was obviously better than before. This provides a certain reference value for supercritical and ultra-supercritical CFB boilers to achieve the target of lower energy consumption.
