The optimal soot blower occasion and the soot blower period were determined based on the accumulation degree of ash and slag on the heated surfaces of boiler,the sonic soot blower system was designed and the program was compiled.

During steam blowing process,steam blowing quality is being ensured,steam blowing period is being shortened and generating unit commissioning course is being quickened,through establishing effective measure of storing and draining water,engaging exhaustive work and optimizing.

Experiments are carried out on influences of critical parameters of dust removal cycle,filtration speed and medium dimension on filtration and classification efficiency and dust diameter distributions after filtration are obtained which is taken as a standard for judging influential extent of filtration parameters.

Experiments were carried out on influences of critical parameters of dust removal cycle,filtration speed,and medium dimension on filtration classification efficiency.

The velocity time sequence at different vertical and longitudinal locations in a turbulent boundary layer with periodic blow-suction disturbance is finely measured by IFA-300 constant-temperature anemometer with resolution higher than the frequency that corresponds to Kolmogorov dissipative scale.

In this paper, the technique of constant temperature anemometry, together with double-hot-wire-sensor probe, is used to carry out experimental study on the turbulent boundary layer, which is controlled by periodic blow-suction disturbance in the low turbulent level wind channel.
