A, temperature and pressure reducing device according to the inlet pressure and temperature can be divided into:
1 medium temperature and medium temperature and medium temperature and pressure reducing device:
Primary steam parameters (inlet steam parameters): pressure P1=3.9MPa; temperature t1=450;
Two steam parameters (outlet steam parameters): pressure P2 determined by the user requirements; temperature t2= saturation temperature;
Flow: Q=2 ~ 360t/h (T / h)
2 high pressure and temperature reducing and pressure reducing device:
Primary steam parameters (inlet steam parameters): pressure P1=5.4MPa; temperature t1=485;
Two steam parameters (outlet steam parameters): pressure P2 determined by the user requirements; temperature t2= saturation temperature;
Flow: Q=20 ~ 200t/h (T / h)
3 high temperature and high pressure temperature and pressure reducing device:
Primary steam parameters (inlet steam parameters): pressure P1=10MPa; temperature t1=540;
Two steam parameters (outlet steam parameters): pressure P2 determined by the user requirements; temperature t2= saturation temperature;
Flow: Q=30 ~ 240t/h (T / h)
B, temperature and pressure reduction device of the main technical indicators
1 temperature and pressure reduction device outlet flow
The outlet steam flow rate of the temperature and pressure relief device is 30%Q~100%Q, and the special needs can be negotiated by the supply and demand sides.
2 temperature and pressure relief devices rated outlet steam pressure P2
The deviation range of the rated outlet steam pressure of the temperature and pressure reducing device is:
When the rated outlet steam pressure is less than P2, for 0.98MPa + 0.04MPa
When the rated outlet steam pressure is not more than 3.82MPa, for P2 + 0.06MPa
When the rated outlet steam pressure is greater than P2, for 3.82MPa + 0.15MPa
3 rated outlet steam temperature T2
Rated outlet steam temperature must be above saturation temperature (including saturation temperature)
The minimum deviation range of nominal outlet steam temperature is rated at outlet steam temperature T2 + 5
4 temperature and pressure reduction device problem noise
During the normal operation of the temperature and pressure relief device, the noise at the outlet of the temperature reducing and pressure reducing valve (1m) is measured at the same level of the outlet center line, and the overall noise level is less than 85dB (A). If users have special requirements, can be determined by the supply and demand sides negotiated settlement.
Reducing the pressure without loss of energy, and through the device can increase the amount of steam supply. Simple structure, no rotating parts, reliable operation. Easy to operate, easy to repair, can be automatically adjusted. Significant energy saving effect.
