Selection of boiler evaporation capacity
Thread Content
Help: There are two autoclaves, 2.68m×38m; the approximate volume is 428 cubic meters. It is now required to fill both autoclaves with saturated steam at 1.2 MPa within 1 hour. May I ask: what size of boiler with evaporation capacity should be chosen? How to calculate it? Thank you!
The gauge pressure is 1.2 MPa and the absolute pressure is 1.3 MPa. According to the saturated steam property table, the specific volume of saturated steam at this pressure is 0.15112 m³/Kg. Therefore, 428 cubic meters of saturated steam corresponds to approximately 2.8 tons, which is a suitable amount for a 3-ton boiler.
