The pressure reducing desuperheating system consists of pressure reducing system, temperature reducing system, safety protection device and automatic control device.
According to the primary steam pressure P1, temperature T1 can be divided into high temperature and high pressure temperature reducing and pressure reducing device, medium temperature and medium pressure temperature reducing and pressure reducing device, low pressure temperature reducing and pressure reducing device. According to the use can be divided into temperature reducing device, pressure reducing device, temperature reducing and pressure reducing device. According to the use of different power can be divided into pneumatic/ hydraulic/ electric temperature and pressure reduction device
1. Adopts the structure of temperature reducing and pressure reducing valve, so that the length of the whole device is greatly shortened, the area of occupation is reduced, and the project investment is reduced.
2. Protect the valve seat and valve body, prolong the service life of the valve, and also reduce the noise of the device.Double - seat valve unbalance force small, wide range of regulation, smooth action, must not appear stuck phenomenon.
3. Reduce the leakage of the valve and reasonably distribute the pressure difference on the water supply system. The same caliber, different flow coefficient Cv value can be selected, which greatly improves the sensitivity and accuracy of the temperature regulating system.
4. Further improves the sensitivity and accuracy of the regulating system.
The pressure reducing desuperheating system is composed of a control system, a pressure reducer system, a water-jet temperature reducer system and a safety protection system.Its characteristics are as follows:
Temperature reduction and pressure reduction device is the conversion device of steam energy, steam in the high-pressure superheated state of the minimum energy loss, temperature reduction and pressure reduction device is mainly to power stations, boilers, thermal power plants and other transmission of high temperature and high pressure superheated steam for pressure and temperature regulation, in order to reach the downstream users need thermal energy and dynamic parameters.Thus rational use of heat energy, to ensure the safety of pipe network and equipment.The working process of desuperature is to spray desuperative water directly into a steam through the nozzle of desuperative water line for mixing desuperature
The equipment shall be transported to the buyer's site by our party, and the engineering and technical personnel from both parties shall be responsible for supervising the delivery one by one according to the list of supply scope. During the installation and commissioning of the equipment, we will send engineering and technical personnel to the site for free debugging and assist the trial operation of the equipment.
During the warranty period - in case of failure or abnormal operation, after receiving information feedback, we will send engineering and technical personnel to the site in time for maintenance and service. After the normal operation of the equipment, we will analyze the causes. If it is our responsibility, all expenses shall be borne by us; if it is your responsibility, we will only charge the cost.
After the warranty period of the equipment - we only charge the cost for the spare parts we provide. In the process of equipment operation, as long as the demander requires, we will send engineering and technical personnel to the site for technical services at any time.
