Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to heating network heaters, in particular to an impact-proof heating network heater. Background Art
[0002] The heating network heater is a key device of the heating network system and one of the main auxiliary equipment of the thermal power plant. Its main function is to use the steam extraction from the steam turbine or the steam (heating medium) drawn from the boiler to heat the circulating water in the hot water supply system to meet the requirements of heating users.
[0003] During the use of the heating network heater, there is high-temperature steam outside the tube and cold water inside the tube. The temperature difference between the inside and outside of the tube is large, and the shell side is easily caused to operate under negative pressure. At this time, the steam density is small, the specific volume is large, and the volume flow rate of steam is too large. The steam inlet is prone to impact vibration, which causes the heating network heater to vibrate. In addition, during the use of the heating network heater, due to pressure fluctuations, thermal expansion force, reaction force and torque impact when the safety valve is opened, the heating network heater will become unstable, not safe and reliable, thus affecting the stability of the heating system.
