2. Install the grate and put a circle of vertical bricks (24 cm high) along the bottom of the inner wall of the iron drum, then put horizontal bars with appropriate length on the bricks every 1 cm and fix them with mud or cement. Spread two layers of vertical bricks around the iron drum above the grate, and then put mud on the furnace. It is best to plaster the furnace into a slightly pot bottom shape, so that the fuel can be concentrated in the middle of the nozzle, and the inner diameter of the furnace is about 35 cm. Don't light the fire until the stove is dry. )
3. Installation of Nozzle Nozzle is the key component of gasifier. Because of the high temperature in the furnace, the nozzle is easy to be damaged, so it is required to use a special nozzle. The nozzle can be fixed with flange (easy to replace) or directly welded on the iron drum (it can be welded and cut again if necessary). 4. Installation of the water collecting bottle The function of the water collecting bottle is to collect the accumulated water in the pipeline and remove tar, and at the same time, it has the function of safe pressure limitation.
5. Indoor cookware Installation After the gasifier cookware is normally ignited, the flame should be blue-red, and the room is smokeless, dust-free and tasteless. The cooker should be placed by the window, and a row of fans should be added to the window above the cooker to exhaust the oil smoke in the kitchen when cooking.
[Secret of Gasifier Scam] Circuit diagram of Gasifier Scam "Magic" Environmental protection Gasifier is seriously polluted.
A few days ago, our column reported the scam of gasifier. Many unscrupulous dealers advertise gasifiers with high-tech concepts and signboards of universities and research institutes, and tens of thousands of consumers are fooled. In the market, there are still a large number of gasifier manufacturers still misleading consumers under the banner of energy saving and environmental protection. What is even more frightening is that the gasifiers on the market are not only environmentally friendly, but also emit carcinogenic tar. In order to further remind consumers and avoid being fooled, our reporter continued to conduct an in-depth investigation.
Gasifier manufacturers promote gasifiers as energy-saving and environmentally-friendly new products, and all gasifiers they sell are labeled with tar-free labels. Is that really the case? Fan of Xibi Village, Xingtang County, Hebei Province, was lured by Guanggao to buy five magical tar-free gasifiers at a time and tried them at home, but the results were quite different.
Fan, a villager in Xiqiao Village, Xingtang County, Hebei Province, said: "Like Fan's experience, users who bought a gasifier encountered similar troubles as soon as they used it. Some farmers who have cooked in the gasifier in Yangquan, Shanxi, even dare not go out. "
Li Chi of Shanxi Wang Jiajia Science and Trade Company said, "This smell is particularly unpleasant. After the housewife has finished eating at home, people will smell it from far away. You can know the taste after using the gasifier, which is particularly stinging. In view of this situation, people didn't use it later. "
Jia Zhenhang, secretary general of china association of rural energy industry Energy-saving Stove Professional Committee, said that the waste generated by gasification and combustion of straw and other materials is extremely harmful.
Jia Zhenhang, secretary general of China Energy-saving Stove Professional Committee, said: "As far as the gasifier is concerned, the straw gas it produces is mainly carbon monoxide gas, which is not suitable for civil use. In other words, we can't send carbon monoxide-based gas to thousands of households of ordinary people. The most terrible thing is that when the gas stove is used, the room is full of tar vapor, not just a pungent smell, because tar vapor is a strong carcinogen. "
Zhang Yuxin, a stove manufacturer in Tengzhou, Shandong, said: "This tar is mainly a carcinogen, which is harmful to people's health. If it is sprinkled on the ground, for example, in the field, crops will never grow."
Gasifier scam 2 The big secret of gasifier promotion has been unsuccessful.
Experts say that using straw as fuel gas has extremely low calorific value, and its content is mainly carbon monoxide, which is about 18% to 2 1%. This content of carbon monoxide is just at the explosion limit and at the same time at the poisoning limit. A few years ago, many scientific research enthusiasts studied the gasifier as a good project that could be popularized. Gasifiers have been popularized in many areas of China. What was the result? Continue to watch the reporter's investigation.
Ma is the general manager of Chongqing Science and Technology Co., Ltd. He is optimistic about the prospect of gasifier. In 2006, it invested heavily in the introduction of gasifier projects, invested in the construction of 500,000 gasifier production lines, and sold nearly 10,000 gasifier products nationwide. Results Due to the inherent defects of the product, the problems exposed in use were not solved, and the company lost nearly 20 million yuan. .
General manager of Ma Chongqing Technology Co., Ltd.: "People will become scrap iron in a short time. At that time, we saw that ordinary people earned a little money, which was very difficult in our southwest. "
It is not only those investors who have suffered losses, but also the promotion and use in some places, and most of them have hastily withdrawn their troops. Wang Tianshou is a staff member of the Energy Office in Bijie District, Guizhou Province. In 200 1 year, in order to make use of the waste such as straw in rural areas, they began to promote the gasifier project in Bijie area, and began to try it out among 200 villagers.
Wang Tianshou, Energy Office of Bijie District, Guizhou Province: "As a result of spot checks, only 5 of these 200 households have stoves with fire, and the others are useless. Using a gasifier is to find gas, find gas by yourself, and take gas by yourself. "
The magical gasifier has no magical effect. In less than a month, 200 gasifiers in the village soon became "furnishings". In fact, gasifier technology was locked in the laboratory as early as 20 years ago because of technical defects and congenital deficiencies.
Hao, director of the china association of rural energy industry Energy-saving Stove Professional Committee, said: "If we want to trace back to the source, it was the national gas stove project undertaken by China Agricultural Mechanization Research Institute in the early 1990s. From the demonstration effect, it was not bad, but there were many structural defects when it was put into practical use, so this product was shelved, and it was not widely promoted later, and then it slowly flowed to the society."
Gasifier technology looks beautiful
A technology with structural defects, a melting pot with congenital defects, has attracted many people into it. At first glance, using straw, wheat straw, corn straw, branches and sawdust as fuel, directly put into the furnace, gas can be generated in a few minutes, which can be used for cooking, cooking, bathing and heating. Today, with more and more attention paid to energy conservation, it is considered by many people to be a project with broad market prospects. Because it looks beautiful.
We don't seem to see any flaws in the advertisement of gasifier, and it feels like a new technology of energy saving and environmental protection.
Jia Zhenhang, Secretary General of China Energy-saving Stove Professional Committee: "Why can straw gasifier be popularized? Because the straw gasifier has good camouflage and strong performance. "
Next, let's take a look at the pictures of our reporter's unannounced visit to Changping, Beijing. Gasifier manufacturers lead reporters directly. Next to the burning gasification, the blue flame is burning, but the reporter is not allowed to see the raw material bucket where the straw is put.
After reading it for less than two minutes, the manufacturer quickly urged the reporter to leave. Why?
Su, general manager of Dafeng Biotechnology Co., Ltd.: "Generally speaking, he wants to show you and show you that the general effect is better;" However, the duration is short, usually 4 or 5 minutes, 10 minutes. If adjusted well, it can last for about half an hour. So if you want to test this product, you must test it for a long time. Generally speaking, as long as you insist on one thing, it will not be fooled, because it is turned off, it just appears. "
Insiders told reporters that these gasifier enterprises are very consistent in deception in the market, and they are willing to spend money on advertising and put a lot of advertisements in the media, which is very tempting. Most consumers only buy gasifiers after watching advertisements.
Join-I lied to you, no discussion.
After advertising in the media, if you want to buy a gasifier for your own use, it is absolutely impossible. The users chosen by these gasifier manufacturers are very picky-that is, entrepreneurs who want to make a fortune, and their main way is to join.
When the reporter made an unannounced visit to Qingda Lianke gasifier manufacturer in Beijing, he proposed to buy a gasifier. The marketing manager said he would definitely not buy it, but urged us to engage in franchise sales. All advertisements issued by gasifier enterprises are "welcome interested parties to join our sales network and sell gasifiers." And talked about the benefits of joining chain sales.
But when consumers actually sign the franchise contract, they find that there are traps everywhere. Not only can it not be returned, but it is also impossible to get back the deposit.
In the franchise contract of gasifier sales, the phenomenon of collecting deposit is the most. Many manufacturers charge deposits ranging from 8,000 yuan to 1000 yuan to 10,000 yuan under the pretext of exclusive agency in the region, technology transfer and technology confidentiality, and promise to deliver goods free of charge.
General Manager of Lu Bao Biotechnology Company in Dafeng City, Jiangsu Province: "For example, if you pay 10,000 yuan, I will give you 30,000 shops. Generally speaking, at first glance, alas, I can buy 30 thousand goods for 10 thousand. Didn't I earn 20 thousand yuan back? But on the whole, it deceives amateurs. If you carefully calculate an account, its cost of 30,000 yuan will be several thousand dollars. "
Fraud roadmap
A crude product with technical defects, which seriously pollutes the environment and human safety, has been put on the coat of high-tech and environmental protection, and thousands of farmers have suffered greatly. Finally, let's summarize the tricks of scammers and look at their fraud roadmap.
First of all, these fraudulent companies will promote their products under the banner of universities such as Tsinghua and Peking University. Renting office buildings near universities such as Tsinghua, with high-grade decoration, makes people feel that the company does have contact with Tsinghua. In the product introduction, they will also claim that their gasifier products are the research products of a professor in Tsinghua, and have obtained patent certificates and so on.
Next, fraudulent companies will spend a lot of money to advertise in various media. Advertisements generally claim that gasifier is a good project with high technology and environmental protection. There are raw materials everywhere, which can burn for hours, without tar and pollution.
Then, when consumers are attracted by false advertisements and come to the door for consultation, the liar company will demonstrate the use of the gasifier. Although it is advertised in their advertisements that the gasifier can burn for several hours, when consumers watch on the spot, the staff of these companies only let them watch for a while, and then eagerly ask consumers to sign a franchise contract. Finally, they use advertising fees and transportation fees as bait to attract consumers. For example, some gasifier companies promise to reward advertising expenses of 40,000 yuan for selling 500 units.
It is worth noting that these fraudulent companies generally only accept foreign consumers. This is because foreign consumers can only admit that they are unlucky after being cheated because of their long distance and weak strength. When consumers spend seven or eight thousand yuan to join the company and get back a few stoves, they find it is just a pile of garbage. After demanding something in return, these swindlers began to play hide-and-seek to cheat money.
