Understand the working principle of cremation furnace in high temperature weather.
After drinking four liters of water for a long time, the taste became heavier and I like salty food.
On the morning of July 14, the reporter came to babaoshan funeral home North Crematorium. Ten working cremators lined up and the machines rumbled. As soon as I entered the door, a heat wave hit. Although the indoor ventilation system is running at full capacity, I still feel bored. As the business of cremating remains is mainly concentrated in the morning, 1 1 is busy in the morning, and the cremation machine can't stop for a moment. The body is scheduled, scanned, put into the furnace, the furnace pressure is observed, the ashes are restrained, and the kang surface is cleaned ... After a trip, the gray work clothes are "switched" back and forth between "dry" and "wet" several times.
Jiang Yubin, the squad leader of the cremation room, told the reporter that the burning temperature in the cremation furnace is 1300 degrees Celsius, and the temperature of the freshly burned kang surface is so high, and the temperature of the cooled kang surface can reach hundreds of degrees Celsius. Although the cremation room is equipped with ventilation system, it is a drop in the bucket. "It's summer. When the outdoor temperature is 37.8 degrees Celsius, the indoor temperature must be at least 40 degrees Celsius. " Zhang Qi, a fireman who has just finished dusting and cleaning the kang surface, looks sweaty. His work clothes were soaked with sweat, and the front and back of his clothes were covered with layers of white salt. In the morning, he can't remember how many times his clothes were wet with sweat.
Sweating has become the norm here. "I drank nearly four liters of water in the morning, which was converted into a bottle of 550 ml mineral water, about seven bottles." Jiang Yubin said that a colleague brought a big cup that can hold two liters of water. When it is hot these two days, they can drink two large bottles in one morning. The normal daily water demand of an adult is about 2.5 liters. There are two small doors in the North Crematorium. Before installing the gate outside the cremation room, these two small doors were closed all the year round, and the room was closed, more like a big steamer. "Now, the gate was just installed last month, and these two small doors can be opened." Jiang Yubin said that during work breaks, most cremators are willing to stand by and blow air, or sit on the bench outside to enjoy the most natural coolness. "Every time we work, we are sweating. We don't want to blow air conditioners for fear of catching a cold. "
The more you sweat, the more salt you lose. In order to supplement salt, the cremator's diet has also become more "heavy". Jiang Yubin revealed, "Masters will deliberately eat a little salty when eating, put more salt when cooking at home, and take the initiative to eat more pickles to supplement salt when eating in the unit canteen."
I was burned when I collected the ashes, and the hair on my forearm was baked off.
At this moment, the prompt light of No.2 cremation furnace lit up, indicating that the body in the furnace had been cremated. After the worker's operation, the oven door is slowly opened, and it can be seen that the furnace is burning red, and the temperature inside is about 1300 degrees Celsius. The kang surface and the remains are slowly pushed out and lifted, and cooled by the rapid cooling system.
15 minutes later, the kang surface cooled, and the kang surface and the remains were pushed out. Jiang Yubin and his partner Plateau began to converge the ashes. Although it is already cold, the temperature on the kang surface is still several hundred degrees Celsius. The reporter put his hand ten centimeters away from the kang surface and still felt the scorching baking. Jiang Yubin constantly reminded reporters that the residual temperature on the kang surface is still very high, so don't touch any metal plates around the kang surface.
A minute later, all the bones on the kang surface converged, sweating all over his face. The reporter accompanied the two men to stand next to the kang surface, and their cheeks were red with high temperature. The reporter tried to put on the heat-insulating gloves that Jiang Yubin had just taken off. The gloves had been wet by Jiang Yubin's sweat and were still emitting hot air.
Convergent ashes should be pointed at the hot kang surface, and your hands will be thrown back and forth on the kang surface, and you will be burned if you are not careful. Plateau showed his right forearm to reporters, and the skin on it was wrinkled and rough as goose bumps due to long-term baking and lack of water. The two previously burned scars on the kang surface are clearly visible, and the hairs on the inner side of the forearm have been basically burned.
After the ashes converged, a special high-temperature vacuum cleaner was moved to the plateau and began to carefully clean the burning residue on the kang surface. "Many family members will put some funerary objects in the coffin, and these residues must be cleaned up, otherwise they will be sorry for the next deceased." After a while, the plateau's face was wet with sweat again.
In the process of burning the remains, the cremator should observe the burning flame in the furnace from time to time and master the air pressure data in the furnace through the control panel. On the operating surface of the cremator, each cremator has a small iron gate, which can open the hearth, where the combustion can be observed. Because it is close to the combustion chamber, the temperature here is higher than that in the cremation hall. "Every time I open the small iron gate of the stove, there will be a heat wave rushing out, and my face will suddenly sweat. If I wasn't careful, I burned my hair on my forehead. " Jiang Yubin said.
The second floor of the cremation room, such as a steamer, patrols for half an hour every day.
Subsequently, the reporter followed Jiang Yubin to the second floor of the cremation room, where the post-processing equipment of the cremation furnace and several staff offices were concentrated. Due to the rising heat, the reporter obviously felt that the air on the second floor was hotter than that on the first floor. In the computer room, iron gates, iron railings, iron stairs and iron equipment abound. Even the ground is hot, and the heat is gathered here, just like a big steamer. In order to ensure the normal operation of the equipment, Jiang Yubin, as the monitor, has to patrol the north-south crematorium twice a day, one machine 19, and one patrol takes 15 minutes, while the temperature on the second floor is even higher than the outdoor temperature. He smiled and made an analogy to the reporter: "When the road outside can spread eggs, it is definitely better to spread eggs here than outside.
Generally, the business of babaoshan funeral home crematorium will end at one or two in the afternoon, with an average daily business volume of about 75 pieces. Yesterday, the business volume was not too big, and 5 1 corpse was cremated. At 2 o'clock in the afternoon, all the other workers got off work, and Jiang Yubin, who was on duty these two days, had to clean the stove. "I have to wait until seven or eight o'clock in the evening to clean the inside of the stove. At that time, the temperature was still seventy or eighty degrees. " In order to prevent burns, Jiang Yubin will wear long-sleeved overalls in winter. "That would be even more boring. After sweeping the 10 stove for more than half an hour, the clothes were soaked again. "
Cremator is really hard, no matter winter or summer, year after year, day after day, give them a compliment!
