Chapter 26: The Basin of Fire
On July 16, he and his comrades were practicing the 4×100-meter relay in the playground of Anshan University of Science and Technology, which is the training subject of the fire army. At this time, Zhang Xiangzhong, chief of the combat training section, called and said that there was a fire in Dalian, and the leader sent you to arrive at the fire scene with the command vehicle in the first batch.
On the way back to the detachment by taxi, Zhang Chaoyang was still thinking: It takes 3 hours to drive the fire water tanker to Dalian, and the general fire has been saved in 3 hours, and it is estimated that there is nothing to do. Zhang Chaoyang served as an instructor of the special service squadron of the Anshan Fire Detachment, was born in 1977 and enlisted in the army in 1995. The special service is a trump card in any detachment, and it is inseparable from emergencies and dangers. Regarding the fire in Dalian, Zhang Chaoyang didn't think too deeply.
At 20 o'clock, Zhang Chaoyang boarded the command car and galloped to Dalian, and there were two situations that made him tighten the strings in his heart. First, the communication intercom transmitted an order from Liu Leguo, deputy director of the Liaoning Provincial Public Security Department, so that Yang Baoliang, chief of staff of the Anshan City Public Security Fire Detachment, immediately called back. Zhang Chaoyang participated in the fire-fighting battle, and the deputy director asked the chief of staff of the detachment to call back This is the first time, this fire is not small. The second is that on the Shenyang-Dalian Expressway, more and more cars are walking, all of them are public security fire vehicles, and the red police lights converge into an endless river, and the fire does not know how big it is.
When he arrived at the fire, Zhang Chaoyang was stunned at first glance, what kind of fire is this? Like the rising sun in the sea, the red is boundless, and there is no way to judge how large the area is. This fire can't be saved, this is Zhang Chaoyang's first feeling. The second feeling made Zhang Chaoyang very sad, that is, in such a big fire, the brother of the Dalian Public Security Fire Detachment held out for 7 hours? He faced the sea of fire in the red night sky and thought, are they still in there? Thinking about the fate of the comrades-in-arms of the Dalian detachment, tears welled up in my eyes.
Zhang Chaoyang didn't know that this was just the beginning, and it was this sea of fire that he wanted to devote himself to. I don't know what kind of test awaits him.
The position of the Anshan City Public Security Fire Detachment is in the Nanhai Tank Farm.
The key point of this position is the connecting box (valve group).
No. 1 connecting box is installed between No. 42 tank and No. 47 tank, and No. 2 connecting box is installed between No. 47 tank and No. 48 tank. Crude oil is fed in or out of tanks through connected tanks. The top and left and right directions of the connecting tank are connected to the oil pipeline, and the bottom is the sewage ditch. After the explosion of tank No. 103, the flowing fire carried crude oil into the sewage ditch and barbecued the box. Several pipes burst, spewing oil fires outward. If—and this is only if—the tank is burned and the oil fire is poured directly into the No. 37, No. 42, No. 47, No. 48, No. 49 and No. 50 crude oil tanks, the six crude oil tanks with a reserve of 100,000 tons will explode and catch fire. What does a 600,000-ton crude oil tank look like when it explodes and catches fire? No one has ever seen this situation, maybe it's not *** powerful, maybe it's better than ***. But one thing is predictable: the area of the fire will be 6 times larger than it is now. Only one No. 103 tank burst out and caught fire, forming a 60,000-square-meter burned area. Exploding 6 canisters is a 360,000-square-meter fire field, and the Dagushan Peninsula is submerged and burned to ashes. Therefore, extinguishing the fire in the box was a matter of life and death for the 130 officers and men of the Anshan City Public Security Fire Detachment. To paraphrase an old saying, it is called "swear to live and die with the box", but this is just a cliché. The belief in the hearts of every firefighter is to swear to survive with the company and not let the officers and soldiers suffer casualties.
The leader of the detachment conveyed the instructions of the superiors: The task of the Anshan City Public Security Fire Detachment is to protect the box and prevent a chain explosion from occurring in the Nanhai tank farm.
However, the No. 1 tank had already exploded, and this tank was next to the No. 42 crude oil tank, and because of the explosion of the tank, an oil pipeline was blown out of a hole with a diameter of one meter, and flames more than 30 meters high were sprayed outward, and the No. 42 tank was being scorched. Zhang Chaoyang calculated the time, and the No. 42 jar had been roasted for 6 hours. At present, the ditch is full of fire, and the box is being barbecued.
Zhang Chaoyang's position was set up between tanks 47 and 48, and the task was to extinguish all the fires in the sewage ditch 100 meters deep and relieve the No. 42 tank from heating.
Tank No. 42 was 100 meters away from Zhang Chaoyang's position, and it had to be pushed closer 100 meters if the No. 42 tank was to be relieved of the heat. Zhang Chaoyang looked at the No. 42 oil tank behind the fire and couldn't help but sigh, the big oil tank with a height of 22 meters and a diameter of 80 meters would have burst if it was filled with light oil, and it was because it was crude oil that it did not burst. But once burned, crude oil is much more entanglement than light oil such as gasoline. Light oil volatilizes quickly and burns rapidly, and crude oil burns like a mudslide, like a mountain collapse, and can submerge and bulldoze any steel and concrete objects.
They set up two foam guns and two mobile self-swinging guns in the position, and fiercely blocked the flowing fire in the ditch. The P016 foam gun could control the fire of 50 square meters, and the PQ200 vehicle-mounted cannon hit the flowing fire in the ditch under the No. 48 tank. The pressure of the foam cannon and the foam gun and the ability to isolate the air still can't suppress the oil fire, and it burns back immediately after pushing it over. The quality of the crude oil is quite heavy, and the design performance of the foam gun and foam cannon probably did not consider attacking the crude oil fire, and the designer probably did not see the crude oil fire.
At this time, there is a shortage of ammunition. Attack with insufficient foam and water supply, fight out in vain, and return to the original position after the fire. It didn't take much time to finish the foam and water they had brought with them. Now the first requirement is to find water, beg grandpa, sue grandma, and hate to kneel down in order to get enough water. The fire water source in the PetroChina reservoir area has become a waste because of the power outage. At the fire ground on July 16, it was not uncommon for officers and men of various detachments to have disputes over finding water. Zhang Chaoyang's position was fortunate that they found a water source within 20 minutes. They asked for two water supply lines from the remote water supply brigade of the Dalian Public Security Fire Detachment, one line connected to 10 water belt outlets, and connected the seawater to the fire truck. After that, 60 barrels of 209 kilograms of foam were unloaded from the foam truck of the Dalian detachment and all of them were injected into the car of the Anshan City Public Security Fire Detachment.
They continued to push forward, getting closer and closer to Tank 42, approaching Tank 1. To get close to tank No. 42, the only way to go is a small bridge, which is not wide, and the culvert under the bridge is blocked with cement. This is close to the No. 1 burst pipeline, from which more than 30 meters of flames are erupting, like a crater at the head of the bridge.
Zhang Chaoyang and the others rushed onto the bridge, but the people couldn't stand on the bridge at all. Professional combat boots seem to be just a layer of paper, and there is no place to put them on your feet. Aluminum foil insulating clothing, which was originally able to withstand high temperatures and flames, is like a single layer of clothing here. The trench fire is like two walls, burning on both sides of the bridge. Zhang Chaoyang and the others retreated, drove the car onto the bridge, and used the vehicle-mounted cannon to suppress the trench fire with maximum pressure. The vehicle-mounted cannon produces 60 liters of foaming water per second, which is equivalent to 10 water guns, and 20 tons of water are shot in 3 minutes, with a range of 50 square meters.
The ditch fire was a little more honest, and Zhang Chaoyang and four or five comrades-in-arms went to the bridge to set up mobile guns. When the pressure of the cannon was increased to the maximum, three or four people could not hold it. The driver pressed the accelerator all the way down, added 20 pressures, and the flow rate of 60 liters per second at this time was very powerful, and the cannon seemed to be crazy. People can't hold the cannon because the bridge deck is full of oil, and it is slippery when kneeling and squatting. When the pressure of the mobile gun was at its highest, the mouth of the water pipe collapsed and was changed several times. Later, they tied mobile guns to the cement piers of the small bridge and hit the large hole in the broken and burning box of the No. 1 company. White smoke rises when it hits, and you can't see the target clearly. Zhang Chaoyang stood on the side, using gestures to direct the foam flow to attack the target, up and down, left and right, hit the fire point, a total of more than an hour, the fire was extinguished, and the No. 42 tank was safe.
Zhang Chaoyang said this, stood up and repeated: "The No. 42 tank is safe." Security understood, understood? Tank No. 42 is safe. ”
Zhang Chaoyang deeply felt that the victory was not only safe, but also glad that he was not injured. He was particularly vulnerable to injuries when fighting fires, and he was injured in a fall, and he was unconscious when he was injured, but this time he was safe.
In April 2005, a large explosion occurred in the silicon steel workshop of Anshan Iron and Steel Corporation. Silicon steel requires gas, hydrogen, and oxygen to be mixed together to support the tower. As a result of the accident, a gas pipeline caught fire, which ignited hydrogen. Is hydrogen still available? The explosion is the most powerful. Zhang Chaoyang and the soldiers came to the fire site, and when they couldn't reach it, they climbed the 4-meter-high tower and used dry powder to extinguish the burning hydrogen and gas.
Zhang Chaoyang put on an air respirator on his back, rode the pipe to the front of the fire little by little, and beat the fire root with dry powder. While it was playing, the eye shield of the air breathing apparatus was blurred, and the root of the fire could not be seen clearly. He took off his air respirator, which broke down, and he breathed in a large amount of gas without noticing it. Extinguishing the fire, Zhang Chaoyang was top-heavy when he retreated, and he planted it from a 4-meter-high platform. At that time, his weight, including soaked clothes and air respirators, weighed more than 100 kilograms, and he passed out immediately after falling to the ground. His comrades-in-arms sent him to Tiedong Hospital for a week, his head was clear from the gas, but his legs could not stand up, and it took a while to recover.
In January 2007, a construction site in Anshan used a grappling hook machine to demolish an old residential building, scratching a gas pipeline, and exploding and catching fire. After the gas leak, it went down and gathered in the trenches. The gas on the ground burns, and the gas that is isolated from the air underground is lurking. Zhang Chaoyang led two soldiers to extinguish the fire and rescue, he pulled the broken bricks and tiles, looking for the leakage of the gas pipeline, and there was a big explosion with a "bang", which collapsed Zhang Chaoyang more than one meter high, and he didn't know anything at that time.
Saying that the No. 42 tank on the position of the Anshan detachment was safe and sound, Zhang Chaoyang had a pride on his face that could not be concealed. He said: "The fire in the burst pipe of the No. 1 box was 30 meters high, and the fire was only about 10 meters away from the No. 42 tank, the tank had turned from black to white, the moisturizing layer had been deformed, and the tank began to bulge outward. All crude oil tank explosions and fires start with tank deformation. A 100,000-ton crude oil tank was roasted on a 30-meter-high fire for 6 hours in a row, who is not afraid? Now that the tank has been deformed, maybe the next second crude oil will burst out of the weakest point of the deformed tank and flood this basin of fire......"
However, Zhang Chaoyang proudly said that we extinguished the fire of the broken pipe of the No. 1 box, and the No. 42 tank was unharmed.
After the fire was extinguished, Zhang Chaoyang learned from PetroChina employees that the No. 42 tank was full and contained 100,000 tons of crude oil.
