    Steam Purging Target Plate Seat, Target Plate Holder, Target Plate Axis, Target Plate Device


    When purging, adopt the method of alternate blowing and segmented blowing, and the blowing coefficient is not less than 1 (blowing coefficient = blowing pipe steam flow square number × specific volume of steam when blowing pipe / rated load steam flow square number × rated load ratio of steam volume). Under the condition that the discharge pipe diameter is greater than or equal to the diameter of the purge pipeline and the control valve is fully opened, the purge load reaches 60-70% of the operating load, and when the outlet pressure of the superheater is controlled to exceed 1.0mpa, the blowpipe coefficient can be guaranteed to be greater than 1. 4.8 Eligibility criteria for target shooting: The particle size of the spot on the target board is less than 1mm in diameter, and the trace ≯ 3/cm2, and it is qualified twice in a row. The purge results are classified and recorded, and each target board is kept for inspection.


    According to regulations, the blowing coefficient of each section of the superheater, reheater and its pipeline should be greater than 1, and the blowing system = (steam flow during blowing) 2×(steam specific volume during blowing)/(rated load steam flow) 2×(rated Steam specific volume under load), so you can calculate the blowpipe coefficient. There are two basic methods for steam blowing: constant pressure blowing and decompression blowing. It is not advisable to blow more than 4 times per hour. The main scope of blowpipe: boiler superheater, reheater and their systems; main steam pipe, reheated steam cold section pipe and hot section pipe; high-pressure bypass system; steam-driven feed water pump steam source pipe. The control door should be fully opened during purging; when used for heat storage and pressure reduction method, the opening time of the control door should generally be less than 1 min. Before the formal purge, perform 2 to 3 pre-purges lower than the selected purge pressure to check the condition of the purge temporary equipment and familiarize yourself with the control operation. Generally, the pre-purging pressure can be selected according to 30%-40%, 50%-60%, 70%-80% of the selected blowpipe pressure.




    Acceptance criteria for boiler steam blowing pipe
    (1) Use aluminum as the material of the target plate for the flushing pipe, its length is not less than the inner diameter of the temporary pipe, and the width is 8% of the inner diameter of the temporary pipe.
    (2) The purge coefficient of each section of the flushing system is greater than 1.0.
    (3) Spot particle size: no spot larger than 0.8mm, no larger than 8 spots of 0.5-0.8mm (including 0.8mm), uniform distribution of spots of 0.2-0.5mm, and spots of less than 0.2mm are not counted.
