| 摘要 |
The invention provides a steam manufacturing device and an operation method thereof, which enable the moisture of the steam flowed into a compressor to be constant. The steam manufacturing device comprises a heat exchanger (30) enabling the supplied water to be evaporated by transmitting the heat of a heat exchange medium, the compressor (40) compressing the steam, a flow adjusting valve (21) and a control device (50). The control device (50) obtains the necessary heat (Q2) by multiplying the sensible heat from a supplying temperature to a vaporization temperature of the supplied water by the water supplying quantity of the supplied water and a predetermined dryness threshold value, and compares the necessary heat (Q2) with the loss heat (Q1) lost by the heat exchange of the heat exchange medium, and when the necessary heat (Q2) excesses the loss heat (Q1), uses the flow adjusting valve (21) to throttle to thereby reduce the water supplying quantity of the supplied water; and when the necessary heat (Q2) is lower than the loss heat (Q1), increases the degree of opening of the flow adjusting valve (21) to thereby increase the water supplying quantity of the supplied water. |
