【Commentary】Gao Xicheng, 36, is a boiler worker in the power boiler area of the second public engineering department of Lanzhou Petrochemical Company, and has been engaged in boiler device operation for 13 years. Recently, the reporter walked into Lanzhou Petrochemical Company, Gao Xicheng was observing the combustion state of the boiler by looking at the color of the furnace. According to Gao Xicheng, coal-fired boilers undertake the important responsibility of ensuring the supply of power steam and process steam in the chemical zone. Looking at the color of the furnace fire every day, watching the shape of the slag, listening to the sound of the operation of various equipment of the fan and coal mill, and ensuring the normal operation of the boiler device has become Gao Xicheng's daily work. Now he seems to be very comfortable with this job, but it was actually difficult at first.

After graduating from school, I heard that I was assigned to this boiler device, because I had never seen such a large boiler before, and what I thought was similar to a boiling water boiler, which was nothing more than making a fire and boiling water. But really to the boiler site to see this is not the case, our boiler is very large, we have never seen such a large before, the real operation is still quite difficult. For example, when our boiler burns, we must observe the flame, observe the shape of the slag, adjust the air distribution, and adjust the boiler load according to the needs of users.

【Explanation】The maximum temperature of the boiler device can reach more than 1,000 degrees when running, but Gao Xicheng still insists on observing the color of the furnace fire from the fire hole every day to see the shape of the slag to ensure that the boiler burns to the best. Over time, Gao Xicheng also summed up his own set of experiences.

Just came in is to follow the master to watch the fire, through slowly looking at the fire found that when the flame color is golden yellow, this time is the best burning, fuel combustion is sufficient, flame temperature is also high. When the flame color is white, it is peroxygenation, and peroxygen is equivalent to a large amount of cold air going in, and more air will also reduce our thermal efficiency. Another is that the flame is not fully burned when it is dark, that is, part of the fuel is not fully burned, which is also reducing our thermal efficiency. In order to improve thermal efficiency, we found by observing the flame that the flame is the best to burn when it is golden yellow, and the thermal efficiency is also the highest.

【Explanation】In order to ensure the normal operation of the boiler device, Gao Xicheng also practiced the ability to judge whether the equipment was abnormal by listening to the sound of the operation of various equipment of fans and coal mills.

When I first entered the factory, I was not familiar with the site, and I felt that the noise on the site was particularly loud, but I got used to it. After getting used to it, I suddenly heard a different voice, which may be a problem on the spot. When you hear all kinds of strange sounds in the back, you can accurately determine where it is, and you can basically find the cause.

【Commentary】When he first joined the work, Gao Xicheng followed the master to the scene every day, learning crafts, learning processes, and learning equipment. Over the years, with his efforts, he grew into the youngest squad leader and the youngest special technician in the factory, and participated in solving more than 10 technical problems of power boiler devices. He has successively won the honorary titles of Top Ten Outstanding Young Persons of Lanzhou Petrochemical Company and "Technical Expert" in Gansu Province.

The boiler unit is characterized by high temperature, high pressure and noise, and large dust on site. But each device has the characteristics of each device. I thought that since I came to this position, I had to do this job well and do the best boiler worker.
