How to put a temperature and pressure reducer into use
Thread Content
The 3.5 MPa steam is reduced to 2.2 MPa using a temperature and pressure regulator; the specific steps are not detailed enough in the operating procedures
Deoxygenated water is injected into the temperature and pressure reducer via a control valve to regulate the flow, thereby reducing the pressure and temperature after the temperature and pressure reducer.
—Check that all components are in good condition; complete the construction work, and ensure the site is clean with no debris. Connect the thermal instruments and protections, as well as the steam and desuperheating water control valves. Once everything is functioning properly, close them. Check the positions of the valves that regulate steam flow into the system, and ensure the flow path is unobstructed. In a cold state, first open the drain valve located before the outlet valve of the desuperheating regulator, and allow some steam to flow through to warm the pipes; this will enable the drain valve to discharge condensate. When the exhaust steam temperature rises above 290°C, start using desuperheating water to keep the exhaust steam temperature between 260°C and 290°C. Once everything is working properly, activate the automatic control for the exhaust steam temperature, and close all the drain valves； Manually control the main steam inlet control valve of the temperature reduction regulator to ensure that the main steam pressure and temperature in the preheating furnace rise simultaneously to the specified parameters
If saturated steam is delivered, can it be converted into superheated steam using a pressure reduction device? ? In other words, the pressure is reduced without the temperature being lowered.
