Description

一种锅炉潜在故障识别方法以及装置A boiler potential fault identification method and device

技术领域technical field

本发明涉及智能识别技术领域,更具体地说涉及一种锅炉潜在故障识别方法以及装置。The invention relates to the technical field of intelligent identification, and more specifically relates to a method and a device for identifying a potential failure of a boiler.

背景技术Background technique

锅炉是一种日常生活中常见的能量转换装置,其适用于生活中的方方面面,例如供暖、发电等。锅炉是一种利用燃料燃烧后释放的热能或工业生产中的余热传递给容器内的水,使水达到所需要的温度或一定压力蒸汽的热力设备。锅炉在“锅”与“炉”两部分同时进行,水进入锅炉以后,在汽水系统中锅炉受热面将吸收的热量传递给水,使水加热成一定温度和压力的热水或生成蒸汽,被引出应用。在燃烧设备部分,燃料燃烧不断放出热量,燃烧产生的高温烟气通过热的传播,将热量传递给锅炉受热面,而本身温度逐渐降低,最后由烟囱排出。A boiler is a common energy conversion device in daily life, which is applicable to all aspects of life, such as heating, power generation, etc. A boiler is a thermal device that uses the heat energy released after fuel combustion or the waste heat in industrial production to transfer to the water in the container to make the water reach the required temperature or steam at a certain pressure. The boiler is operated in two parts of the "pot" and "furnace" at the same time. After the water enters the boiler, the heating surface of the boiler in the steam-water system transfers the absorbed heat to the water, so that the water is heated into hot water at a certain temperature and pressure or steam is drawn out. application. In the part of the combustion equipment, the combustion of the fuel continuously releases heat. The high-temperature flue gas generated by the combustion transfers the heat to the heating surface of the boiler through heat transmission, and the temperature itself gradually decreases, and finally it is discharged from the chimney.

现有的锅炉装置普遍通过多个安装在锅炉不同位置上的传感器以及检测锅炉的实时运行参数,并通过锅炉的运行参数实时地检测锅炉是否出现故障,虽然这种检测方案尽管能够及时地检测出故障,但是故障被检测出来时也就意味着故障已经发生了,因此或多或少都会造成设备的损坏,从而造成经济损失。即现有的锅炉装置并没有配置相应的,对其潜在故障进行识别预测的功能,导致现有的锅炉装置出现故障风险较高。Existing boiler devices generally use multiple sensors installed in different positions of the boiler to detect the real-time operating parameters of the boiler, and detect whether the boiler is faulty in real time through the operating parameters of the boiler, although this detection scheme can detect in time Fault, but when the fault is detected, it means that the fault has occurred, so more or less it will cause damage to the equipment, resulting in economic losses. That is, the existing boiler equipment is not equipped with the corresponding function of identifying and predicting potential failures, resulting in a high risk of failure of the existing boiler equipment.
