Chapter 705 Overheating (continued)
In the palace, the boiler room, a workbench next to a boiler under maintenance, heating technician Zhang Jinbao explained a device sweating profusely. The reason why he was so nervous was because there were two listeners in front of him, one was the emperor and the other was the prince.
Zhang Jinbao is a technical school graduate. He is very honest and devotes himself to technology. Because he is willing to endure hardships, study hard, has a flexible mind, and has strong hands-on ability, he performs well. He is highly valued by the owner of the "Welcome Spring" trading company and goes to the palace to be on duty and is responsible for solving various heating problems.
Now, the emperor and the prince are discussing technical issues with him.
This kind of thing is so incredible that Zhang Jinbao was a little overwhelmed. When he first explained, he stuttered and his thoughts were confused, so he was a little incoherent.
Fortunately, a few days ago, he was fortunate to have the emperor praised him in person and reported his work situation to the emperor. He knew that the emperor was approachable, so he quickly calmed down and introduced to the emperor and the prince a technology he had just obtained a patent:
Use a set of devices to process the "saturated steam" generated in the boiler and convert it into "superheated steam" with higher temperatures.
"Superheated steam" and "saturated steam" can tell the difference just by listening to the names.
In the boiler, steam mixed with water reaches saturation in a confined space, which is saturated steam.
However, superheated steam is different. It is to remove the "saturated steam" from water, obtain "dry steam" and then heat it up, which is "superheated steam".
This "superheated steam" is a new term in the field of steam technology and is considered to be Zhang Jinbao's first creation.
The cause of the incident is related to the heating principle: the boiler supplies hot water to the radiator in the room through heating pipes to heat the indoor air and make the room warm.
If hot water is turned into saturated steam, the heating effect will theoretically be better.
However, the saturated steam will easily cool down by less than 100 degrees, and then condense into water, and the heat will be lost in vain. This requires a high level of insulation effect of the pipeline and is too difficult to handle.
The heating pipes from the boiler room to the radiator in the palace are very long, so steam cooling is inevitable. The technicians need to find a way to keep the steam as close to the "use terminal" as possible.
Even if the temperature will condense into water due to the cooling, more (relative) steam will enter the radiators of each hall.
To this end, technicians from various heating companies are trying to solve this problem, from the simplest thickening of pipe insulation layer to various insulation measures, I have thought of all the ways I can think of over the years.
In the end, everyone found that the most economical way was to use pipes to supply high-temperature hot water, which was too difficult to handle when the cooldown was cooled.
Zhang Jinbao didn't believe in evil, so he took the time to think about it. After thinking about it, he found another way and found a new solution.
That is "gas-liquid separation", separating saturated steam mixed with water, allowing the steam to separate it, obtaining "dry steam", and then using equipment to pressurize and heat the "dry steam".
In this way, the temperature of dry steam increases significantly. When moving in the insulation pipe, even if it drops slightly, it is still far from one hundred degrees, and will not condense into water and will not lose a lot of heat.
Such dry steam can enter the radiator in a gaseous state, releasing more heat in the radiator to heat the indoor air.
Because the temperature of this "dry steam" after reheating is significantly higher than that of saturated steam, Zhang Jinbao calls it "superheated steam".
He has been struggling for several years and has created two devices that can turn the saturated steam in an ordinary boiler into "superheated steam".
These two devices, one is a "gas-liquid separator" and the other is a "superheater". They can be directly installed in the pipes outside the boiler to play a role. They can be said to be a very convenient "modification kit".
The modified boiler has changed from a saturated steam boiler to a superheated steam boiler. The heating effect has been significantly improved without increasing much fuel consumption.
However, after practice, Zhang Jinbao found that the original heating pipes also need to be modified because the pressure of superheated steam is very strong, and the elbows and connections of the original pipes need to be reinforced, otherwise problems will occur.
Zhang Jinbao applied for a patent for this technology and was approved not long ago. When the imperial palace manager heard about this, he specially applied for a bonus for him.
The palace's employment system encourages palace maids and errands to invent and create, and there will be bonuses for this. Although Zhang Jinbao is a "labor dispatcher", he is also qualified to enjoy such treatment.
The matter was reported and reviewed step by step. After the queen accidentally learned about it, she saw that it was a very profound steam technology, so she mentioned it to Yuwen Wen.
Yuwen Wen was in a good mood that day. When he was walking, he specially turned to the "boiler class" and praised Zhang Jinbao (Xiao Zhang), so Yuwen Wen had some impression of the terms "saturated steam" and "superheated steam".
Previously, on the train back to Luoyang from Mengjin, when he heard the prince talk about "saturated steam", he felt something was wrong. Later, he remembered that this "Xiao Zhang" discovered "superheated steam" that was different from "saturated steam".
After listening to Zhang Jinbao's introduction, Yuwen Weicheng murmured: "The temperature is significantly higher than saturated steam?"
Then he looked at Zhang Jinbao and asked, "How high is the steam temperature like this?"
Zhang Jinbao replied: "When you go back to your highness, it is currently around 200 degrees, but it needs to heat up under pressure."
"How many more?" Yuwen Weicheng was stunned when he heard this, thinking that he had auditory hallucinations.
Zhang Jinbao replied again: "When you go back to your highness, the steam temperature can reach about 200 degrees."
"About 200 degrees..." Yuwen Weicheng looked at Zhang Jinbao, his head blank.
How many technicians have worked hard and spent many years raising the steam temperature by thirty degrees to more than one hundred and thirty degrees.
As a result, the steam temperature here is easily up to 200?
"Have you taken the steam engine after the boiler is renovated? How much has the output increased?" Yuwen Weicheng grabbed Zhang Jinbao's shoulder and kept shaking: "Have you measured the expansion force of superheated steam?"
"Ah... Caomin never thought about picking up the steam engine..." Zhang Jinbao was shaken and a little confused.
Yuwen Wen looked at her son, Zhang Jinbao, and then looked at the device made by Zhang Jinbao. He was not clear and thought to himself: It seems that something is amazing...
However, he didn't understand very much, but his son immediately understood.
He specializes in his profession. His son has been specializing in steam engine technology over the years and can be said to be a steam engine expert. He does not need to pay attention to the process, but only needs to know the results. Faced with the emergence of new technologies, it is natural to not keep up.
However, Yuwen Wen looked at his son who was happy and constantly asked about technical details and thought of himself back then.
At that time, everything was blank. He relied on the knowledge in his memory to guide confused technicians to explore various new technologies and inventions. Whenever there was a breakthrough, he would discuss technical details with the technicians and cheer for technological progress.
That feeling is really nostalgic. Now when I think about it, decades have passed.
He no longer has the ability to guide technicians to overcome various technical difficulties. He is like a candle, illuminating the correct direction of scientific and technological development, but he is getting shorter and shorter.
In a blink of an eye, it has been 26 years of Mingde...
