Do you know what a temperature reducer does? Join us as we explore its functions below!!!

(1) Adjust the steam temperature to ensure the steam output from the boiler falls within the specified range. Steam turbines have strict requirements for steam temperature, generally requiring it to be within ±5℃ of the rated temperature, allowing only a fluctuation of 10℃. Exceeding the specified temperature can reduce the lifespan of equipment such as superheaters, steam pipes, turbines, and valves, and in severe cases, can damage them. A temperature below the specified value can decrease the economic efficiency of the unit. A 10℃ decrease in steam temperature can reduce the unit's economic efficiency by 0.6% to 0.8%. Due to the numerous factors affecting steam temperature, adjustments are made to maintain it within the designated range. There are many methods to adjust steam temperature, with the use of desuperheaters being a widely adopted approach.

Protect the superheater, steam turbine, and the corresponding steam pipes and valves. When the steam temperature exceeds 460°C, the high-pressure parts of the steam turbine and the pipeline valves are made of alloy steel. Although alloy steel has a high allowable temperature but is expensive, it is typically operated at the upper limit of its permissible use temperature to reduce costs, with a margin for safety. As long as the steam temperature remains within the specified range, the equipment can operate safely.
