Why use wood for heating?
Three good reasons for heating with wood
1. ecological combustion
amount of CO2 received = amount of CO2 released
wood does not contain sulfur compounds and heavy metals; the absolute amount of CO2 released by burning wood is 40 to 50 times less than when burning other types of fuel
2. economical heating
1m3 of dry wood = 200 m3 of gas or 200 l of light fuel oil
3. perfect combustion in a PYROGAS boiler
minimum amount of ash, which consists exclusively of 100% mineral substances
The development of the use of individual fuel media indicates a return of users to heating with solid fuels, especially wood. Our company, recording this trend, offers the PYROGAS wood gasification boiler with a modern design and top-notch performance.
Wood as an organic substance consists of 80-90 weight percent volatile substances (CO, H, hydrocarbons) with a high energy value. These gases are released from the wood mass at temperatures around 200 °C. In order to burn with maximum benefit, it is necessary to heat the wood to high temperatures and keep it in the high temperature range for as long as possible, so that the released gases are sufficiently mixed with the combustion air and thus their perfect temperature conversion occurs.
In conventionally designed wood-burning boilers, the flue gases are blown directly through heat exchangers. A significant part of the gases is not burned out and is released into the atmosphere in the form of unwanted emissions, which causes insufficient use of the wood energy, i.e. lower efficiency. Wood gasification boilers are designed so that the flue gases are directed from the firebox into the refractory concrete combustion chamber, where they have enough time to burn out completely. Therefore, these boilers achieve an efficiency of 89% and more and low emissions of harmful substances.
TREE - A PURE NATURAL PRODUCT
Plants are able to absorb solar energy and store it. During photosynthesis, carbon dioxide CO2 and water are converted into organic matter and are stored in the wood as energy. During combustion, this energy is released again and used as heat. The amount of CO2 absorbed during wood growth is the same as the amount of CO2 released during combustion, i.e. wood as a material is neutral in terms of CO2 content and therefore does not burden the environment, unlike fossil fuels.
