GenGaz - Lagunov
My name is Sergey Lagunov and I am a professional engineer, one of the best practitioners in the gas generator business.
During 10 years of my practical activity, I built about 10 industrial gas generators with my own hands (from the project to the turnkey material object) and God knows how many small ones, including wood-burning cars. It was I who came up with the idea in the distant 2013 to revive the technology of gas generation in our space. All that was then was a couple of dozen books in the network. I had to rephotograph about 600 books on gas generation with my own hands and read them on my last channel (which was destroyed by YouTube). During the activity, many followers appeared (there were 16,000 subscribers at the time of the channel's destruction) who picked up the idea and spread the knowledge. I tirelessly popularized this topic for 10 years. YouTube destroyed 500 videos.

⚙️ Genius Soviet Engineering: The "Smart" Furnace That Sorts Coal Automatically
I came across an interesting patent from Soviet engineers dating back to 1965. At first glance, it seems like a standard coal-processing furnace (gasifier), but inside lies an incredibly elegant solution to a problem that many designers have struggled with for decades.
What was the issue? 🤔 Usually, if you load a furnace with a mix of coal (both large chunks and fine dust), the results are poor: the fines burn away instantly, while the large stones remain "raw" inside. Traditionally, this required fuel to be crushed and sorted manually beforehand.
💡 How did the Soviet inventors solve this?
They designed an apparatus that handles everything itself, relying solely on gravity and physics.
Automatic Sorting 🏗️ Inclined grates are positioned at the furnace inlet. As the coal is poured in:
Large chunks roll further toward the center (into the heart of the heat).
Fines fall through the grates and land closer to the walls.
The result? The fuel arranges itself into perfect layers automatically!
Clever Airflow 🔥 Inside, the hot gas doesn't move from bottom to top as it usually does; instead, it moves crosswise:
➡️ First, it passes through the layer of large stones, which require maximum heat.
➡️ After transferring some heat, the gas (now slightly cooled) moves through the layer of fines, which need a lower temperature.
🏁 The Result Genius lies in simplicity! Without complex electronics or sensors—using only the strategic design of the grates—the furnace evenly "cooks" fuel of any size. The large stones are fully processed, and the fines are saved from burning to ash.

I'm launching a second Telegram channel (free for everyone to join). It will feature news about gasification technology from around the world (and everything related to gasifiers).
The channel will always remain free.
It's called Gasifier World.
The link to join is: t.me/gasifierworld
Join now. It will start filling up with content soon. It's empty for now, but not for long.

People from all over the world reach out to me for guidance on building a DIY gasifier. One of my students is a professor at a polytechnic institute in Fergana, Uzbekistan. Now, there's a demonstration unit there that attracts visitors from all over the country. If you’re in Uzbekistan, you’ll have a place to come and see it.

A 1-megawatt gasifier for drying sand in Germany. Seeking an investor. The investment is about 50,000 euros (1-megawatt gasifier + drum dryer). The first year's profit with taxes already paid is 0.344 million euros, the second year is 1 million euros, and the fifth year is 5 million euros. I am attaching the economic calculation. docs.google.com/spreadsheets/d/1KwTB_SK0iBONr0sXUg…

Hydrogen has fairly unusual and sometimes contradictory properties. For example, itsresearch octane rating (RON) is very high while its motor octane rating (MON) is low. This indicates that hydrogen has a very low resistance to knock, which can be explained by its lowignition energy and extremely high flame speed. In a mixture, however, hydrogen acts in theopposite way by increasing the overall knock resistance. This is explained by the trade-offthat the mixture’s ignitability is less improved by the hydrogen addition than are the flamespeed and thermal diffusivity. Improved flame speed limits the time for knock to occur, whilethe high thermal diffusivity of hydrogen limits the risk of high-temperature gas pockets in thecombustion chamber that could initiate knock or pre-ignition. The reduced risk of knock andpre-ignition means that the compression ratio of the engine can be increased, which increasesthermal efficiency.
The improved ignitability due to hydrogen addition is very beneficial as well, since thisenables very lean engine operation. Under these conditions, combustion temperatures can bedecreased, which results in extremely low NOx emissions.The combustion of hydrogen with oxygen produces water and forms no hazardous emissions.It should be remembered that variations of the hydrogen content of the producer gas exert asignificant influence on combustion phasing, meaning that the engine controls need to bedesigned to respond so as to avoid load changes, increased emissions, or even engine damage.
Furthermore, pure H2 has some challenging properties regarding, for example, diffusivity, thatneed to be addressed if in high concentrations. Hydrogen is thus incompatible with manysteels, nickel and its alloys, titanium alloys (pure titanium works well, though), and cobalt andits alloys, which can be susceptible to hydrogen brittleness or that are permeable to hydrogen,permitting it to diffuse (leak) through. Hydrogen’s extreme flammability makes it importantto avoid static spark discharges by properly grounding materials in contact with hydrogen. Inmixtures, such as producer gas, in which the hydrogen content seldom exceeds 30%, theproblems are not as extreme as in pure hydrogen

Artificial intelligence is helpful, but it recommends seeking the assistance of a specialist. Without professionals, it's difficult to make progress.

I produce small wood gas generators in Kyiv on order for generating electricity ranging from 1 to 8 kW. On request, I also provide sketches for those who want to build their own generator. I would be delighted to expand the production of these devices in Europe.
Links to videos about the devices.

I thank those who have subscribed to the channel and signed up for a sponsorship. Today we have a new sponsor! Thank you!
The topic I cover is not as popular as singers and movie stars, and it's very difficult to earn a living from it. It's also challenging to make videos that have very few views because few people are interested in it.
Those who have signed up for a sponsorship greatly help me continue to make new videos! Support is inspiring. Thank you for sponsoring the channel!
