On-line Monitoring System and Method for Heat Exchange Efficiency of Horizontal High Pressure Heater

Abstract

The invention discloses an on-line monitoring system and method for heat exchange efficiency of a horizontal high-pressure heater. A flow measuring device, a pressure measuring device and a temperature measuring device are installed on corresponding pipelines of the horizontal high-pressure heater, as well as data acquisition and control System, to obtain the corresponding flow, pressure and temperature, in order to calculate the heat transfer efficiency of the horizontal high pressure heater. Through the online monitoring system and method for the heat exchange efficiency of the horizontal high-pressure heater of the present invention, the heat exchange efficiency of the horizontal high-pressure heater can be understood in real time, which helps to adjust the operating state of the horizontal high-pressure heater in time, and is beneficial to energy saving, consumption reduction, and increase in energy consumption. The heat transfer efficiency of the horizontal high-pressure heater is monitored in real time. According to the change of the heat transfer efficiency, accidents can be found in time. Water entering the cylinder of the steam turbine caused further expansion of the accident.

Description

technical field [0001] The invention relates to the technical field of heaters, in particular to an on-line monitoring system and method for the heat exchange efficiency of a horizontal high-pressure heater. Background technique [0002] The thermal cycle of the steam turbine generator set uses steam extraction from the steam turbine cylinder to heat the boiler feed water, so as to improve the cycle thermal efficiency of the unit. The economy of the entire turbo-generator set. At present, there is a lack of heat exchange efficiency monitoring devices or systems for horizontal high-pressure heaters, which makes it impossible to grasp the heat exchange efficiency of horizontal high-pressure heaters in real time during operation. Uncertainty creates a lot of waste when high pressure heaters run inefficiently for extended periods of time. SUMMARY OF THE INVENTION [0003] In view of the above deficiencies, the present invention provides an on-line monitoring system and metho...
