Step 1: the controller (2) is obtained in Boiler Steam supply line part in real time by the first steam pressure sensor
Steam pressure signal, the steam pressure in gas utilization unit connecting line part is obtained by the second steam pressure sensor in real time
Signal obtains the steam flow signal in gas utilization unit connecting line part by flowmeter in real time；
Step 2: when the controller (2) detect that steam flow rate of change is less than preset standard value by the flowmeter
When, the steam pressure in Boiler Steam supply line part that the controller (2) is detected based on the first steam pressure sensor
Signal controls the aperture of the boiler pressure control valve (V1), and being set with vapour based on second steam pressure sensor detection
The steam pressure signal control aperture with vapour pressure force control valve (V2) in standby connecting line part；
Step 3: when the controller (2) detect that steam flow rate of change is more than or equal to pre- bidding by the flowmeter
When quasi- value, the controller (2) generates the adjustment signal for being proportional to steam flow variable quantity and rate of change, and is based on the tune
The superposed signal of section signal and the steam pressure signal of the first steam pressure sensor detection controls to control the boiler pressure
The aperture of valve (V1), while the superposition of the steam pressure signal detected based on the adjustment signal and the second steam pressure sensor
Signal controls the aperture with vapour pressure force control valve (V2).
10. FAST RESPONSE according to claim 9, which is characterized in that
Wherein in step 2, preset when the controller (2) detects that steam flow rate of change is less than by the flowmeter
When standard value, further when the controller (2) detects that Boiler Steam is supplied by first steam pressure sensor
When vapour pressure force value in pipeline portions is greater than preset value, the aperture of controller control boiler pressure control valve (V1) is with just
Than increasing in the mode of vapour pressure force value in Boiler Steam supply line part, further when the controller (2) passes through institute
It is described when stating the second steam pressure sensor and detecting that vapour pressure force value in gas utilization unit connecting line part is less than preset value
Controller control is with the aperture of vapour pressure force control valve (V2) to be inversely proportional to vapour pressure force value in gas utilization unit connecting line part
Mode increases；
Wherein in step 3, when the controller (2) detects that steam flow rate of change is more than or equal to by the flowmeter
When preset standard value, the controller (2) generates the adjustment signal value for being proportional to steam flow variable quantity and rate of change, goes forward side by side
One step is detected in Boiler Steam supply line part when the controller (2) by first steam pressure sensor
When vapour pressure force value is greater than preset value, the aperture of controller control boiler pressure control valve (V1) is to be proportional to Boiler Steam
The mode of the superposition value of vapour pressure force value and the adjustment signal value increases in supply line part, further when the control
Device (2) detects that the vapour pressure force value in gas utilization unit connecting line part is less than in advance by second steam pressure sensor
If when value, the controller control is steamed with the aperture of vapour pressure force control valve (V2) with being inversely proportional in gas utilization unit connecting line part
The mode of the difference of vapour pressure force value and the adjustment signal value increases.
