Wood pyrolysis boiler
Wood pyrolysis boiler -- build it yourself!
Man is created in such a way that he is attracted by the new and unknown. With time we gain experience and knowledge. Our dreams and ideas take on a pragmatic nature. We raise a family, take on certain obligations and seek to create comfort, while minimizing the costs when possible. It is our God-given lot in life to live in a country in which many need to do things for themselves. We delve and explore specialized industry to learn and we are lucky if we feel rewarded in the process. I am one of those. I am interested in the process of creating things that seem unrealistic for the common man who lacks specialized equipment and conditions. I like to gather information, crumb by crumb, experiment, reflect on the situation and ultimately get results. One of my work experiences has been to build a 50 kilowatt pyrolysis boiler at home.https://kotel50.narod.ru/ Since then many have repeated the design and I think that many will do so in the future. The wood pyrolysis boiler is an alternative to the gas boiler. Many people in Ukraine live in smaller homes, and I have often been asked if it is possible to build a smaller boiler. I decided to build a 30 kilowatt boiler, with operating time from one fueling of not less than 10 hours. I redesigned the construction of the burner. In contrast to the 50 kW boiler, in this one the fuel combustion does not occur in the grate. Instead, a vertical steel slit burner is used. This is a more advanced technology. There are also ceramic burners, but clay that isn't affected by temperatures around 1,300 degrees C isn’t available locally. Therefore I used heat-resistant steel. All work was carried out at home, and anyone who knows how to weld and use an angled grinder could replicate the process. It takes me about 70 man-hours to produce one boiler. Ahead of the heating season, it would be interesting to observe the boiler in action. However, it is already clear that the boiler is worth the effort. During the test run, the boiler worked very well, the flame was clean and smooth and there was no smoke from the exhaust pipe!
For those of you who are considering whether or not you want to have a pyrolysis boiler in your home, I can say that in my opinion, it’s a no-brainer. This boiler is highly useful in the present circumstances. It is easy to use, reliable and economical. Moreover, if you build it yourself, it will not be expensive. If you, the entrepreneur, have the necessary ability and want to set up the production of such boilers, I would be happy to help you.
