Otaku Engineer in Great Tang Dynasty

"Hmm~! This mutton is delicious to eat! How can there be good wine without good meat? Xiaoxuan, let people get the wine! My father, your grandfather and I have a good drink~!"

Others said that Cheng Yaojin was killed halfway through, but Li Zexuan was half eating hot pot today, and he had Cheng Yaojin!

The old fairy came here to see how the vegetables in the Li family's greenhouses look like, because his family's Zhuangzi and Qin Qiong's family's Zhuangzi have recently introduced greenhouse vegetable cultivation techniques.

The results of it! The old vegetable in the greenhouse didn't even look at it. As soon as he entered the house, his eyes were fixed on the lamb, fish and dipping sauce on the table.

With Cheng Yaojin for so long, how could Li Zexuan not understand this old guy's mind? So he didn't say anything, and directly invited Cheng Yaojin to have hot pot with him! Anyway, as this old guy, there is no need to worry about Wuhou arresting him because of the curfew when it gets dark for a while!

Cheng Yaojin gave Li Zexuan an approving look, then sat down unceremoniously and ate together.

As the saying goes, eating large pieces of meat, drinking from a large bowl, and eating for a while, Cheng Yaojin felt a little uncomfortable, so he yelled for Li Zexuan to get the wine!

Li Zexuan had no choice but to let Sambo go to the wine cellar to hold a jar of gods drunk.

After the wine came on the court, the atmosphere became more lively. Cheng Yaojin has a refreshing nature, and he has been familiar with Daddy Li for a long time. Ye Guozhong has been in a high position for a long time, and he is also well-informed. The three of them still have common topics. For a while, the coveting is staggered, so lively!

Li Zexuan felt that Cheng Yaojin’s wines were not good, and he only wanted to eat hot pot, he didn’t want to drink too much, so he didn’t mix with them, and he didn’t eat well with Lan Er, Madam Li and Old Lady Ye. Happy!

After drinking and eating, Cheng Yaojin returned home with a burp and drunken satisfaction. When he left, the old guy swayed and did not forget to confess to Li Zexuan: "Hiccup~! Xiaoxuan~ you! This hot pot at home, hiccup~, it's so... so delicious! I will send my cook over here, hiccup~, you...you have to be taught...teach him! I have not eaten it for a long time. So full, hiccup~, drinking so much!"

The old guy had forgotten his original intention of coming to Li's house, but he only remembered the hot pot. I have to say that in the absence of war, appetite is Lao Cheng's greatest pursuit now!

……………………………

On the second day, near noon, Li Mansion.

"Feiji, you send these drawings to the workshop, give them to Fu Bo, let him make them in two days!"

Li Zexuan called Pang Feiji, took out two drawings, handed them over, and ordered.

"Yes! Lord Hou~!"

Pang Feiji led the way.

On the other hand, Li Zexuan had a coal stove and a basket of briquettes carried on the carriage. Coal was still burning in the stove. Then he rode the carriage towards the palace and he was going to see Li Er.

As for the drawings just given to Pang Feiji, they are the radiator and heating pipe drawings he just drew in the morning. The structure is quite simple. He has already measured the size in the morning. The drawings of the other courtyard were all made by him, so naturally there is no need to measure them.

Li Zexuan plans to install self-made heating for the mansion and Yunshan Courtyard.

Anyway, now there are briquettes and coal stoves. Just set up a pot and drain some pipes. It's basically OK!

This is what he modeled on some homemade heating in the countryside in his previous life, and the principle is also very simple:

A large water-heating boiler, the furnace is double-layered, the top and bottom are closed, the top is connected with steel pipes and the water layer is connected from the flue to the heating water supply. This point is the lowest point of the water supply pipe, and the heating end is the highest point. Exhaust valve, gradient of one percent;

The bottom is flat to connect the heating return water, and then the return water pipe is connected to the water supply pipe next to the furnace, and the height exceeds the highest point of the water supply pipe, and then a water supply tank is installed. The return pipe next to the furnace is the lowest point and the highest point of the heating section is one-hundredth of the slope;

The water in the furnace tank becomes steam rising after being heated, and becomes a mixture of hot water and steam through the water supply pipe to the highest point. After the hot water enters the radiator, the temperature decreases, the density increases, and the volume becomes smaller. Thereby forming a circulation loop.

The **** of the water pipe for self-made heating is very important. Falling slopes will cause no heat. The boiler water layer should be thin, 1-3 mm. Because the water layer is thicker, coal will be charged. The high point exhaust valve must be open, otherwise the whole system will be closed. , There will be an explosion!

The reason why Li Zexuan has only started heating up now is mainly because there was no briquette or coal stove before. It is very inconvenient to boil water, because the continuous burning ability of charcoal is far inferior to that of briquette! Now that he has made briquettes and coal stoves, of course he must quickly install the heating at home!

.……………………………………

In the imperial palace, Li Er returned to the Xiyuan Lizheng Hall just after the morning, because there are charcoal basins and heaters here!

Although he is the emperor of horses, he also has martial arts, but he is still far from the point where the martial arts master can not invade the heat~www.ltnovel.com~ This kind of weather, he will also feel cold!

Li Er had just spoken with the Empress Changsun in Lizhengdian for a short while, when the Huangmen servant came to report

"Your Majesty, see you Yonganhou!"

Li Eryi was taken aback, and then laughed out, "Oh? When will this kid take the initiative to come to me? Does he say why?"

Since Li Zexuan entered the officialdom, most of them were brought into the palace by Li Er summoning him. It is still extremely rare to take the initiative to enter the palace like today!

"Back to your Majesty, Yonganhou said that he is here to offer treasures!"

The waiter replied cautiously.

"Presenting treasures? Ha~! This new thing is really one after another today! Let him wait at the Temple of Ganlu first, and I will come right away!"

Li Er was very curious, and he didn't care that it was freezing outside, so he put on a fox fur coat and prepared to meet Li Zexuan at Ganlu Hall.

After all, this is the harem, and Li Zexuan is a normal man who has grown up and is married. Of course he cannot be allowed to come here! If Li Zexuan was not married at the beginning of the year, Li Er might meet him in the harem, but now it is absolutely impossible.

"Your Majesty, my concubine also wants to see what kind of treasure Yong'an Hou is offering. I wonder if I can go with your Majesty?"

But Empress Changsun was also interested, she begged Li Er.

"Haha! Since the maidservant Guanyin is interested, then go with it! But it's very cold outside. You can add another piece of clothing for the maidservant Guanyin!"

Li Er laughed and agreed very readily.

"Thank your majesty for caring, and concubine saves herself!"

Empress Changsun felt warm, and the maid put on a mink fur coat for her, and the couple went out!
