Abstract

The invention relates to an on-line performance diagnostic system and method for a rotary air pre-heater. The system comprises a computer platform (1) and an operation and overhaul department control device (2). A data processing module (3) and a manual handling unit (4) are arranged in the computer platform (1). Information of the data processing module (3) and the manual handling unit (4) comes from a performance diagnostic technological theory module (5). The performance diagnostic technological theory module (5) comprises a diagnostic module (6) for diagnosing whether the cooling air amount reaches a designed value, a corrosive dust accumulation diagnostic module (7), a heat storage element damage diagnostic module (8) and a cold end air leakage diagnostic module (9) and is used for detecting the performance of the air pre-heater. In addition, the air pre-heater performance diagnostic technological theory module, all sub-modules and an operation and overhaul department control platform are connected through a closed-loop management module (10), so that performance abnormity of the air pre-heater is found and eliminated in time, it is ensured that the air pre-heater is always in an efficient running state, and the energy consumption level of a unit is effectively reduced.

Description

technical field [0001] The invention relates to a detection technology of a rotary air preheater in a thermal power plant, in particular to an online performance diagnosis system and method for a rotary air preheater. Background technique [0002] According to the investigation and analysis results of the operation of the rotary air preheater of large-capacity thermal power units, the performance of the air preheater of more than 80% of the units has deteriorated to varying degrees, but most units have not clearly analyzed the reasons for the low efficiency of the air preheater, so they have not taken remedial measures in time , leading to continuous deterioration of the performance of the air preheater, resulting in a decrease in boiler efficiency and an increase in the power consumption rate of the plant. forced down). [0003] For example, the Chinese utility model patent with the application number 201020264408.7 discloses an air sealing device for reducing the air leak...
