1. Unit load size. It has an impact, but not absolutely. The greater the load, the more steam must be condensed for heat exchange. If the cooling effect is not very good, the exhaust pressure will increase and the temperature will rise.
2. The heat exchange effect of the condenser: If there is scale or the air in the water chamber on the cooling water side of the condenser is not exhausted, the cooling effect will be affected. Poor cooling effect --- high exhaust temperature.
3. The circulating water temperature is abnormal. Of course, if the temperature is high, the cooling effect is poor. The exhaust gas temperature will increase.
4. The air extractor is abnormal. When the condenser is operating, there is still non-condensable spent steam that must be continually pumped out. If the condenser operates abnormally, the spent steam cannot beextracted normally, the vacuum will not be maintained and the exhaust pressure and temperature will increase. Generally, as the exhaust gas pressure increases, the exhaust gas temperature also increases.
