Doomsday Bunker Upgrade

In the city police station shelter, in the room where the SWAT team installed the ground source heat pump, Chen Xin has taken off his power armor and is standing next to the ground source heat pump to check the equipment.

For the current SWAT team, the ground source heat pump is a very important piece of equipment. It is precisely because of the existence of the ground source heat pump that the SWAT team can still maintain a certain amount of heating and cooling in this extremely cold weather. Hot water supply allows some people suffering from hypothermia and frostbite to take a hot bath to relieve the damage caused by prolonged exposure to low temperature.

However, the heat supply of ground source heat pump equipment is limited. If the heating is maintained, the bathroom cannot be opened for a long time. Therefore, the bathroom of the SWAT team can only be opened at intervals, and only people with severe frostbite can go in to wash a hot water. Take a shower to relieve frostbite.

"Comrade Chen Xin, is there a way to improve the heat supply of the ground source heat pump?" The political commissar stood beside Chen Xin, watched him check the equipment, and asked him with a bit of anticipation: "Thank you for selling it in the first place. This set of equipment for us has really played a big role! Can you find a way to make the equipment produce more heat energy?

Now we really need more hot water! If you can do it, whatever you need, just speak up! Even if I throw my 200 jins into the boiler and burn me, I will jump in without you needing to do anything! "

Chen Xin heard what the political commissar said, smiled and shook his head and said, "It's not that exaggerated! If you really want to burn coal, burning corpses is a waste of fuel, and the flammable content of the human body is too low! Besides, what is needed to transform the equipment is the material, so what's the use? Gotta burn people?"

"Then, Comrade Chen Xin, what materials do you need? I'll have someone prepare it!" The political commissar saw from Chen Xin's attitude that he was well-informed, and hurriedly asked him what materials were needed for the transformation. Chen Xin came to transform the ground source heat pump.

"I need to add two compressors, the evaporation tank also needs to be enlarged, and new pipes need to be added..." Chen Xin casually said nonsense, counted a few times, and then said to the political commissar: "Get two air conditioner compressors, Then get some steel pipes and iron sheets, which should be enough."

As soon as Chen Xin finished speaking, the political commissar hurriedly wanted to turn around to prepare materials, but was suddenly stopped by Chen Xin.

He patted his head as if remembering something, and said to the political commissar: "Another person will be sent to the Polytechnic Institute to inform the people in the scientific research institution, tell them that I am here, and let them send someone over."

"Okay, I'll arrange it now!" The political commissar saw that Chen Xin finished speaking, and confirmed it before trotting all the way to arrange what Chen Xin said, while Chen Xin looked at the ground source heat pump in front of him and wondered if there was any A better way to improve heating.

When Chen Xin was thinking about the transformation of the ground source heat pump, Uncle Ding also reported to the director about the transformation of the boiler. After obtaining permission, he returned to the SWAT team and found Chen Xin.

"The director has already agreed to rebuild the boiler. Chen Xin, how do you plan to rebuild it? How long does it take to rebuild, and does the boiler need to be shut down?" thing.

Chen Xin thought about it and said, "I want to see the boiler first."

"Okay, I'll have someone take you to check the boiler." Uncle Ding nodded and agreed directly.

—————————————————————

Being led to the boiler room of the city police station shelter, Chen Xin walked to the working boiler, listening to the roar of the roaring flames in the boiler, and feeling the heat wave emanating from the boiler, he knew clearly. nodded.

"It can be changed, no need to stop." Chen Xin turned to look at Uncle Ding, who was with him, and answered his previous question: "But the transformation requires a lot of things, I will make a list later, and the relevant materials are ready. , you can start to transform.”

Hearing Chen Xin say this, Uncle Ding felt a sigh of relief.

How to improve the heating problem in the current extreme cold weather is a problem that plagues all the shelters in the urban area. If Chen Xin can solve this problem, even if it is only temporarily solved, it can save many people's lives and make people feel relieved. Great deeds from Dashi in my heart.

The relieved Uncle Ding also hurriedly urged Chen Xin to list the materials needed for the transformation.

Chen Xin agreed. He didn't take a closer look around the boiler. For the system, it was enough to just see the boiler.

The coal-fired boilers used in medium-sized shelters in urban areas are layer-fired boilers. The advantages of this boiler are that it has less auxiliary equipment, is simple to manufacture and install, and is easy to operate. It is suitable for small and medium-capacity boilers.

However, because its combustion form is to lay the coal blocks on the chain grate for layered combustion, there will be incomplete combustion, and the slag and fly ash have a large content of combustibles. Generally, the efficiency of the boiler can only reach 75- 85%, there is actually a lot of room for transformation.

Of course, this transformation room is for Chen Xin, who owns the system, because he can completely change the combustion method of the boiler equipment without shutting down and dismantling it, and transform it from an inefficient layer-fired type to a more efficient one. Chamber-fired or cyclone.

The difference between these two boilers and the layer-fired boiler is mainly in the combustion method, because both of them use the method of completely crushing the coal into pulverized coal and then fully burning the coal for combustion, so whether the combustion is sufficient The degree or boiler efficiency is much higher than that of the layer-fired type.

However, since the raw coal is screened, crushed and ground into most of the pulverized coal with a particle size of less than 0.1 mm, and then blown into the furnace through the burner for suspension combustion, the supporting equipment required is more than the layer-fired type. There are many more boilers, and the requirements for the level of automation are also very high.

Such boilers are obviously not suitable for use in small and medium-sized shelters, but because chamber-fired boilers can be very large, they are more suitable for use in large shelters.

Therefore, Chen Xin did not choose the chamber furnace as the transformation direction, but chose the cyclone furnace.

Some boilers of this type of combustion are between the layer-fired furnace and the chamber-fired furnace. The pre-cyclone cyclone burns the broken coal particles or coarse coal powder with a particle size of less than 10 mm first in a cyclone-like manner, and then generates high-temperature flue gas. Then enter the main furnace for radiant heat exchange, so that the coal is fully burned to release heat.

Compared with the chamber furnace, the cyclone furnace can also be made very small, so it is very suitable to be used as the transformation direction.

The only problem is that the applicable coal type of the cyclone furnace is limited by the melting point of ash and the viscosity of the slag; the load fluctuation range of the boiler is small, and it cannot be started and stopped quickly.

And because the temperature in the furnace can reach about 2000 ℃, the emission of harmful gas NOx is large, and the air pollution is serious.

But now it is the end of the extreme cold, the boilers are running non-stop, and now the sky is like this, the air pollution can only be a little later, let human beings get through this disaster first, and then survive.
