Abstract

The invention discloses an online monitoring system and an online monitoring method for heat exchange efficiency of a horizontal high-pressure heater. A flow measuring device, a pressure measuring device, a temperature measuring device and a data acquisition and control system are mounted on corresponding pipelines of the horizontal high-pressure heater to acquire corresponding flow, pressure andtemperature, so that the heat exchange efficiency of the horizontal high-pressure heater is calculated. By means of the online monitoring system and the online monitoring method for the heat exchangeefficiency of the horizontal high-pressure heater, the heat exchange efficiency of the horizontal high-pressure heater can be known in real time, the operation state of the horizontal high-pressure heater can be adjusted in time, and the remarkable effects of saving energy, reducing consumption, improving efficiency and creating income are achieved; and the heat exchange efficiency of the horizontal high-pressure heater is monitored in real time, accidents such as heat exchange tube leakage and water supply partition leakage can be found in time according to the change of the heat exchange efficiency, and further expansion of the accidents caused by possible water inflow of a steam turbine cylinder is prevented in advance.

Description

technical field [0001] The invention relates to the technical field of heaters, in particular to an online monitoring system and method for heat exchange efficiency of a horizontal high-pressure heater. Background technique [0002] The thermodynamic cycle of the steam turbine generator set uses steam extraction from the cylinder of the steam turbine to heat the boiler feed water, so as to improve the thermal efficiency of the unit cycle. The economy of the whole turbogenerator set. At present, there is a lack of heat transfer efficiency monitoring devices or systems for horizontal high-pressure heaters, which makes it impossible to grasp the heat transfer efficiency of horizontal high-pressure heaters in real time during operation. The uncertainty of heat transfer efficiency has caused economical problems for the entire turbogenerator set Uncertainty, when the high pressure heater is operated in a low efficiency state for a long time, it causes a lot of waste.
