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

Abstract

The invention discloses a real-time control system and method for the operating efficiency of a horizontal high-pressure heater. A flow measuring device, a pressure measuring device, a temperature measuring device and a valve 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 exchange efficiency of the horizontal high pressure heater, and adjust the heat exchange efficiency of the horizontal high pressure heater by controlling the valve opening to adjust the liquid level to obtain a suitable The heat exchange efficiency and realize the operation efficiency control of the horizontal high pressure heater. The invention can adjust and control the efficiency of the horizontal high-pressure heater in real time, helps to adjust the operating state of the horizontal high-pressure heater in time, and has significant effects on energy saving, consumption reduction, efficiency increase and income creation.

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.
