Description

火力发电厂中挡板开度确定方法及装置Method and device for determining baffle opening in thermal power plant

技术领域Technical field

本发明涉及火力发电厂中挡板控制技术领域,尤指一种火力发电厂中挡板开度确定方法及装置。The invention relates to the technical field of baffle control in thermal power plants, and in particular to a method and device for determining the opening of baffles in thermal power plants.

背景技术Background technique

在火力发电厂中,挡板(风门)是必不可少的部件,其中应用最多的为水平挡板和竖直挡板。在安装、调试现场或机组运行中,均要求挡板开度与电脑端机组运行画面中显示相一致。但机组运行一段时间后,一些挡板难免会因为热胀冷缩、介质的冲刷腐蚀等原因造成挡板开度与电脑端机组运行画面中显示不一致,因此需要定期校核检修。校核的方法通常为运行人员在机组运行画面前,另一名人员在现场,通过二者配合来调节叶片实际角度与画面显示相一致,挡板叶片角度通常由现场人员目测得出。但与水平挡板不同的是,一些竖直挡板所在的流通截面很狭窄,眼睛看不清楚,测量工具又无法接触到,这就不可避免的造成竖直挡板开度无法在电脑上准确显示,导致机组调节特性不良,甚至引发严重后果。In thermal power plants, baffles (dampers) are essential components, among which horizontal baffles and vertical baffles are the most commonly used. At the installation and commissioning site or during unit operation, the baffle opening is required to be consistent with the display on the computer unit operating screen. However, after the unit has been running for a period of time, some baffles will inevitably cause the baffle opening to be inconsistent with the display on the computer unit operating screen due to thermal expansion and contraction, erosion and corrosion of the medium, etc. Therefore, regular calibration and maintenance are required. The method of verification is usually that the operator is in front of the unit operating screen and another person is on site, and the two work together to adjust the actual blade angle to be consistent with the screen display. The baffle blade angle is usually visually determined by the on-site personnel. However, unlike horizontal baffles, some vertical baffles have very narrow circulation sections that are difficult to see clearly with the eyes and cannot be accessed by measuring tools. This inevitably results in the inability to accurately measure the opening of the vertical baffles on the computer. display, leading to poor regulation characteristics of the unit and even serious consequences.

现有技术可以计算煤气混烧锅炉每层风门挡板应达到的开度,不能确定需要达到的开度和挡板实际开度是否吻合。存在竖直挡板开度校核过程中,叶片实际角度目测不准,测量工具又无法接触到,而造成竖直挡板开度无法定量测量等问题。The existing technology can calculate the opening that the air door baffle of each layer of the gas mixed-firing boiler should reach, but it cannot determine whether the required opening matches the actual opening of the baffle. During the verification process of the vertical baffle opening, the actual angle of the blade is not accurately visually measured, and the measuring tools are inaccessible, resulting in the inability to quantitatively measure the vertical baffle opening.
