    In the shelter of the city police station, in the room where the SWAT team installed the ground source heat pump, Chen Xin had taken off his power armor and was standing next to the ground source heat pump checking the condition of 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 heating in the current extremely cold weather.  The hot water supply allows some people suffering from hypothermia and frostbite to take a hot bath to relieve the damage caused by being in a low temperature environment for a long time.

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

    "Comrade Chen Xin, is there any way to improve the heating power of the ground source heat pump?" The political commissar stood next to Chen Xin, watching him inspect the equipment, and asked him with some expectation: "Thanks to you for selling the  The equipment given to us has really helped! Can you think of a way to make the equipment produce more heat energy?

    We really need more hot water now!  If you can do it, whatever you need, just ask!  Even if you throw my two hundred pounds into the boiler and burn it, I'll jump in on my own without you having to do anything!  "

    When Chen Xin heard what the political commissar said, he smiled and shook his head and said: "It's not that exaggerated! If you really want to burn it, you will still be burning coal. Burning corpses is a waste of fuel. The flammable content of the human body is too low! Besides, what is needed to transform the equipment is materials. Where to use them?"  Do you have to burn people?”

    "Comrade Chen Xin, what materials do you need? I'll ask someone to prepare it right now!" The political commissar saw from Chen Xin's attitude that he was already confident, and hurriedly asked him what materials were needed for the transformation. It seemed that he couldn't wait to get it done.  Chen Xin came to transform the ground source heat pump.

    "I need to add two more compressors, the evaporation tank also needs to be enlarged, and new pipes need to be added" Chen Xin muttered casually, and after counting, he said to the political commissar: "Get two air-conditioning compressors.  Then get some steel pipes and iron sheets, these should be enough."

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

    He patted his head as if he remembered something, and said to the political commissar: "Send someone to go to the Polytechnic to inform the people in the scientific research institution, tell them that I am here, and ask them to send someone over."

    "Okay, I'll make arrangements right away!" The political commissar saw Chen Xin finished speaking, confirmed it, and then trotted all the way to arrange what Chen Xin said, while Chen Xin looked at the ground source heat pump in front of him, thinking about whether there was any  A better way to improve heating.

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

    "The director has agreed to renovate the boiler. Chen Xin, how do you plan to renovate it? How long will it take to renovate it? Does the boiler need to be shut down?" Uncle Ding came to Chen Xin, and without being polite to him, he directly asked Chen Xin what he was most concerned about.  things.

    Chen Xin thought for a while and said, "I want to see the boiler first."

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

    After being led to the boiler room of the city police station shelter, Chen Xin walked to the working boiler, listened to the roar of the burning flames in the boiler, and felt the heat waves emitted by the boiler.  nodded.

    "It can be modified, and there is no need to shut down the machine." Chen Xin turned to look at Uncle Ding who was coming with him, and answered his previous question: "But the modification requires a lot of things. I will make a list later and have all the relevant materials ready.  , we can start the transformation.”

    Hearing what Chen Xin said, Uncle Ding suddenly felt relieved.

    How to improve heating in the current extremely cold weather is a problem that plagues all shelters in urban areas. If Chen Xin can solve this problem, even if it is only temporary, it will be able to save many people's lives, which is disappointing.  A great thing for a big stone in my heart.

    And Uncle Ding, who was relieved, quickly urged Chen Xin to list the materials needed for the transformation.

    Chen Xin agreed, but he did not look around the boiler. For the system, it was enough to see the boiler.

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

    ? ?However, because the combustion method is to lay the coal flat on the chain grate for layered combustion, it will have the disadvantages of incomplete combustion and high combustible content in slag and fly ash. The efficiency of the boiler can generally only reach  75-85%, there is actually a lot of room for improvement.

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

    The difference between these two types of boilers and the layer-fired boiler mainly lies in the combustion method, because both of them use the method of completely breaking the coal into pulverized coal and then fully burning it to burn coal. Therefore, whether it is fully burned  The degree and efficiency of the boiler are much higher than those of the layer-fired type.

    However, because the chamber combustion furnace needs to screen, crush and grind the raw coal into pulverized coal with a particle size less than 0.1 mm, and then blow it into the furnace through the burner for suspended combustion, it requires more supporting equipment than the layer combustion type.  There are many more boilers, and the requirements for automation level are also very high.

    Such a boiler is obviously not suitable for use in small and medium-sized shelters, but because the chamber furnace boiler can be made very large, it is more suitable for use in large shelters.

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

    Some boilers with this combustion method are between layer furnaces and chamber furnaces. Crushed coal particles or coarse coal powder with a particle size less than 10 mm are first burned in a cyclone through a front-mounted cyclone to produce high-temperature flue gas.  Then it enters the main furnace for radiation heat exchange, so that the coal can be fully burned to release heat.

    Compared with chamber furnaces, cyclone furnaces can be made very small, so they are very suitable as a modification direction.

    The only problem is that the applicable coal types of the cyclone furnace are limited by the ash melting point and the viscosity of the slag; the boiler load changes within a small range and cannot be started and stopped quickly.

    And because the temperature in the furnace can reach about 2000C, the harmful gas NOx emissions are large, causing serious air pollution.

    But now we are in the extremely cold apocalypse, the boilers are running non-stop, and the sky is like this, the air pollution can only be postponed for a while, so that humans can survive this disaster first.  (Remember the website address: www.hlnovel.com
