Real-time control system and method for operation efficiency of horizontal high-pressure heater

Abstract

The invention discloses a real-time control system and method for the operation efficiency of a horizontal high-pressure heater. A flow measuring device, a pressure measuring device, a temperature measuring device and a valve and a data acquisition and control system are arranged on a corresponding pipeline of a horizontal high-pressure heater for acquiring corresponding flow, pressure and temperature so as to calculate the heat exchange efficiency of the horizontal high-pressure heater, and the heat exchange efficiency of the horizontal high-pressure heater is continuously adjusted by controlling the opening degree of the valve to adjust the liquid level so as to acquire proper heat exchange efficiency and realize the control on the operation efficiency of the horizontal high-pressure heater. The efficiency of the horizontal high-pressure heater can be adjusted and controlled 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.

Description

technical field [0001] The invention relates to the technical field of heaters, in particular to a real-time control system and method for operating efficiency of a horizontal high-pressure heater. Background technique [0002] The thermodynamic cycle of the steam turbine generator unit 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 turbine generator set. After the steam extracted from the steam turbine enters the horizontal high-pressure heater to condense, a certain water level must be maintained to prevent the exhausted steam from being fully condensed and directly flowing out of the drain pipe, resulting in insufficient recovery and utilization of the regenerative heat energy of the extracted steam. Efficiency has a direct impact. When the high-pressure heater operates in a low-efficiency state for a long time, it causes a lot of waste. Therefore, i...

After the steam extracted from the steam turbine enters the horizontal high-pressure heater to condense, a certain water level must be maintained to prevent the exhausted steam from being fully condensed and directly flowing out of the drain pipe, resulting in insufficient recovery and utilization of the regenerative heat energy of the extracted steam. Efficiency has a direct impact. When the high-pressure heater operates in a low-efficiency state for a long time, it causes a lot of waste. Therefore, it is necessary to control the operating efficiency of the high-pressure heater in real time to save energy and increase efficiency.
