Hearth observation device

Abstract

The invention relates to the field of thermal power generation and discloses a hearth observation device. The hearth observation device comprises a camera body and a camera electrically connected to the camera body. The camera body is connected to a hose capable of being bent and shaped, and the camera is fixed to the hose. The hearth observation device can observe flames in a hearth in multiple angles and multiple directions and record observation results, is convenient to carry and can be used for observing the flames in the hearth and observing positions where the shooting environment is poor and the human hand cannot directly arrive.

Description

technical field [0001] The invention relates to the field of thermal power generation, in particular to a furnace observation device. Background technique [0002] In the field of thermal power generation, boilers are the main equipment for thermal power generation and the main device for energy conversion. The combustion status of the boiler can be judged by many combustion data, such as the furnace temperature, the content of incomplete combustion substances in the combustion products, etc., and the direct observation of the furnace flame is an important way to judge the combustion status of the furnace. [0003] At present, there are mainly two ways to directly observe the furnace flame. One is to watch directly with the naked eye through the furnace fire viewing hole or manually watch it with a fire viewing glass. The second is to watch through the furnace flame TV. [0004] Direct viewing with the naked eye through the furnace viewing hole is the basic method to observ...

Problems solved by technology

[0004] Direct viewing with the naked eye through the furnace viewing hole is the basic method to observe the furnace flame without observation equipment, and this method has the following disadvantages: First, it is very dangerous to directly observe the furnace flame. The high-temperature flue gas will produce direct radiation to the face and eyes of people, and the high-temperature radiation may cause serious damage to human skin and eyes, and the high-temperature flue gas in the furnace may be ejected from the fire viewing hole without precaution, causing serious harm to human beings. Severe scalds and burns on the skin and eyes of the human body, causing great harm; second, manual fire viewing cannot record the actual combustion of the flame, which is unfavorable for recording and analyzing data; Manual viewing can only see a small part of the flame, but cannot see the whole picture of the flame

[0005] For the way of viewing the furnace flame through the furnace flame TV, it is usually to shoot the furnace flame through the camera of the flame TV and watch the basic situation of the burning flame in the remote monitoring room, but an inherent disadvantage of this method is that the camera of the flame TV is fixed If it is not moving, it is generally arranged at a certain elevation in the middle of the furnace to shoot the flame in a fixed direction. The position and shooting angle have been fixed after installation. Small

In particular, general power plant boilers and other large boilers use multi-layer combustion to organize combustion. There may be differences in the flame combustion conditions between different layers and in different directions on the same layer. It is obviously impossible to understand the flame only from a fixed position and a fixed angle. The whole picture of combustion, so the flame TV can not really meet the requirements of furnace flame observation and recording

[0006] In addition, the current ordinary cameras are obviously unable to shoot the furnace flame from any angle. First, because the furnace fire observation hole is generally small, the camera body of the ordinary camera is connected with the camera, so it cannot go deep into the furnace. It is impossible to shoot the flame in the furnace from any angle. Second, the temperature of the fire viewing hole is very high under the radiation of the high-temperature flame in the furnace. Ordinary cameras cannot shoot in such a high-temperature environment.
