Device for on-line monitoring residue calendar life of high-temperature pressure-containing member outside furnace and method thereof

Abstract

The invention discloses a device for on-line monitoring the residue calendar life of a high-temperature pressure-containing member outside a furnace and a method thereof. The device is characterized by comprising a computing server of the residue calendar life of the high-temperature pressure-containing member outside the furnace, wherein the compute server of the residue calendar life is connected with a decentralized control device of the power station boiler through a supervisory information monitoring device. The method of the invention comprises the following step: reading on-line measure point data of the power station boiler; determining the least safe allowance of the residue calendar life; and controlling the residue calendar life of the high-temperature pressure-containing member outside the furnace according to the least safe allowance of the residue calendar life. The invention provides the device for on-line monitoring the residue calendar life of the high-temperature pressure-containing member outside the furnace and realizes the on-line calculation and control of the residue calendar life of the low-temperature pressure-containing member outside the furnace.

Description

technical field [0001] The invention relates to an online monitoring method for the remaining calendar life of a high-temperature pressure-bearing component outside a power station boiler, and belongs to the technical field of power station boilers. Background technique [0002] The high-temperature pressure-bearing components outside the furnace, such as high-temperature headers, high-temperature pipes, and desuperheaters of power plant boilers, are characterized by high working temperature, large size, and high cost. They are key components of power plant boilers. During the load operation process of the power plant boiler, the creep life loss occurs in the high temperature pressure-bearing parts outside the high-temperature furnace of the power plant boiler; Unevenness produces relatively large thermal stress and low-cycle fatigue life loss. Improper use and operation will shorten the remaining calendar life of the high-temperature pressure-bearing components outside the ...

Problems solved by technology

During the load operation process of the power plant boiler, the creep life loss occurs in the high temperature pressure-bearing parts outside the high-temperature furnace of the power plant boiler; Unevenness produces relatively large thermal stress and low-cycle fatigue life loss. Improper use and operation will shorten the remaining calendar life of the high-temperature pressure-bearing parts outside the power plant boiler. It is necessary to monitor the remaining calendar life of the high-temperature pressure-bearing parts outside the power plant boiler on-line
