Steam temperature

Hehe, I guess one is overheated and the other is saturated; they can’t be compared. If both are saturated steam, then the pressure at high temperature will definitely be higher than that at low temperature.

The saturation steam temperature at 2.8 MPa is 232℃； The saturation steam temperature at 1.3 MPa is 192°C. If the temperature of your 2.8 MPa steam exceeds 232°C, then it’s more or less as mentioned above.

Based on pressure and temperature, various types of steam are classified as saturated steam and superheated steam. A liquid in a saturated state is called a saturated liquid, and its vapor is called dry saturated vapor (also known as saturated vapor). If saturated steam is continued to be heated, its temperature will rise and exceed the saturation temperature at that pressure. Steam that exceeds the saturation temperature is called superheated steam. The temperature of saturated steam at 2.80 MPa is 230.04℃ ； The temperature of saturated steam at 1.30 MPa is 191.6℃ ； Your company’s high-pressure steam pressure is 2.8 MP, while the low-pressure steam pressure is 1.3 MP; however, the temperature of the high-pressure steam is lower than that of the low-pressure steam. So when it’s at 1.3MP, it must be superheated steam ； 2.8MP could be saturated steam or superheated steam ； However, the overheating degree at 2.8MP is higher, which is why the temperature of the high-pressure steam is lower than that of the low-pressure steam.

Reply to 4#: Goldfish is fine, but the 1.3MP version overheats more, which is why the temperature of the high-pressure steam is lower than that of the low-pressure steam. This was typed by mistake

Reply to 1# 229800197: The low-pressure steam is likely superheated steam, so its temperature is higher than that of high-pressure steam.
