BACKGROUND OF THE INVENTION 1. Field of the Invention
Using multiple steam from boiler steam accumulator
It relates to a method for supplying steam to equipment.
[0002]
2. Description of the Related Art Converter gas generated during hot metal blowing in a converter
Is high temperature, so there is no way to recover this heat.
Various proposals have been made. For example, a filter covering the top of the converter
A heat recovery device is installed on the card to recover heat as steam,
The collected steam is passed through a steam pipe to form a molten steel vacuum processing unit or
It supplies steam-using equipment such as other general factory equipment.
However, steam is generated intermittently because the converter operates intermittently.
Therefore, the generated steam is stored in a steam accumulator and
At a constant pressure to supply steam to the steam pipe,
When the data pressure falls below the required pressure, the steam supply is stopped.
I was
[0003] This will be specifically described with reference to FIG.
You. The steam generated by the converter boiler 1 is a steam accumulator
And supplied to the steam accumulator 2.
The steam is passed through the steam pipe, and the steam use equipment 6 with different required pressures,
7 (for example, if the required pressure of the steam
Higher than the required pressure of the equipment 7). Further
The pressure gauge 3 is provided on the steam accumulator 2 and
Pressure control valves 4 and 5 are provided in the trachea. And control equipment
The device 8 inputs the steam pressure measured by the pressure gauge 3, and

The pressure control valves 4 and 5 are adjusted so that Only
And the steam in the steam accumulator 2 measured by the pressure gauge 3
The pressure becomes less than the required pressure of the high-pressure side steam use equipment 6
And the control device 8 closes both the pressure control valves 4 and 5 and
This is to stop the supply of steam to the steam use facilities 6 and 7.
You.
[0004]
SUMMARY OF THE INVENTION However, the conventional
The law requires that the steam accumulating equipment 7
Despite being able to supply steam from Data 2
Since the supply of steam to the steam using equipment 7 is stopped, the steam
A lot of steam is stored in the gas accumulator 2
Thus, steam is introduced from the converter boiler 1. this
Therefore, the converter operation rate fluctuates and the steam from the converter boiler 1
When the amount of generated gas increases, or when the steam
When the air volume decreases, the steam accumulator 2
Exceeds the steam storage capacity of the steam accumulator 2.
There was a problem that air had to be dissipated into the atmosphere. The present invention
Was made in view of these circumstances, and
Disperse steam into the atmosphere without increasing the size and cost of the muller
Provides a steam supply method using a suppressed steam accumulator
The purpose is to do.
[0005]
According to the present invention, there is provided the present invention having the above-mentioned object.
The method of supplying steam by such a steam accumulator is as follows.
From the steam accumulator of the boiler where the production volume fluctuates,
Steam to multiple steam facilities that require steam at different pressures
In the method for supplying, a steam in the steam accumulator is provided.
The gas pressure is measured and the measured pressure value
While the pressure is higher than the required steam pressure of the equipment, the steam
Steam from the steam accumulator according to the required air pressure
Supply is continued and the measured pressure value is equal to or less than the required steam pressure.
The steam supply to that steam-using facility is stopped.
You.

Steam supply method using the steam accumulator according to the embodiment
The description will be made with reference to FIG. In FIG. 1, 2 is a converter boiler
Steam generated by the boiler 1 and storing steam
6 and 7 are steam-using facilities.
Equipment 6 has a higher required steam pressure than equipment 7 using steam
Shall be. 4 and 5 are on the upstream side of each steam use equipment 6 and 7
The pressure regulating valve 8 provided is a control device, and is a steam accumulator.
The inside of the steam accumulator 2 by the pressure gauge 3 provided in the
The steam pressure of the sample is measured and the measured pressure value P3 is inputted.
Measured pressure value P3 and the previously set steam input facility 6
Required steam P6, and also required
The measured pressure P7 is compared, and the input measured pressure value P3 is
If the pressure falls below the required steam pressure P6, the target steam falls below
Closing the pressure regulating valve 4 provided on the upstream side of the equipment 6 used,
Further, the pressure in the steam accumulator 2 decreases,
The measured pressure value P3 of the total 3 is the required steam pressure of the steam-using equipment 7.
When the pressure falls below P7, the control for closing the pressure regulating valve 5 is performed.
Is going.
Thus, the measurement in the steam accumulator 2
On the basis of the steam pressure, the controller 8 controls the steam use facility 6
Then, the steam of the steam use equipment 7 is stopped.
Until the required steam pressure of the low-pressure steam-using equipment 7
Supply of steam from the accumulator 2 to the steam-using equipment 7
I can do it. Therefore, the amount of steam remaining in the steam accumulator 2
Of the steam accumulator 2 can be reduced.
The steam storage capacity can be expanded. For this reason, the converter
Operating rate fluctuates and steam generation from converter boiler 1 increases
And the amount of steam used by steam-using equipment 6 and 7 is reduced
Can suppress the release of steam
It is assumed that.
[0008]
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIG.
You. Supply from converter boiler 1 to steam accumulator 2
