Temperature control issue of steam pipes
Thread Content
The temperature required in our oven now is 200 degrees. The superheated steam supplied by the thermal power plant has a pressure of 25 kilograms and a temperature of 255 degrees. After passing through the pressure and temperature control valve, the gauge on that valve indicated 230 degrees and 15 kilograms of pressure. But once we reached the oven section, the temperature in the oven never reached 200 degrees. What could be the reason? My idea is that after pressure and temperature adjustment, the superheated steam at 230 degrees and 15 kilograms reaches the working section of the oven; due to the energy consumption in that section, the temperature of the steam gradually drops, and it turns into saturated steam. The temperature of saturated steam at 15 kilograms is 200 degrees, which is why the desired oven temperature of 200 degrees cannot be achieved. Do any experts have any solutions?
It is true that the saturation temperature of 1.5 MPA steam is 200°C, but the steam temperature is not equivalent to the oven temperature.
