35. What is the effect of changes in the inlet temperature of the compressor on the compressor?
An increase in temperature leads to higher exhaust and oil temperatures, affecting the exhaust volume and lubrication performance. It may also lead to a chain shutdown due to high temperatures. Without high-temperature protection, it is even possible for the lubricating oil to catch fire.
(1) An increase in inlet temperature leads to an increase in the amount of rich gas, thereby increasing the load on the compressor. (2) This causes the outlet temperature to rise; once it reaches a certain level, it exceeds the permissible limit, forcing a shutdown. (3) An excessively low inlet temperature not only reduces the amount of rich gas but also affects the gas composition; the low molecular weight of the gas leads to a decrease in the pressure at the compressor outlet.
(1) An increase in inlet temperature leads to an increase in the amount of rich gas, thereby increasing the load on the compressor； (2) An excessively low inlet temperature not only reduces the amount of rich gas but also affects the gas composition; the molecular weight of the gas becomes too low, which can cause surging in the unit in severe cases.
At higher temperatures, the gas richness will certainly increase, which in turn raises the load on the turbine. Meanwhile, the cooling load on the intercooler also increases accordingly; in severe cases, this can affect the subsequent operations related to absorption and stabilization.
