Home » Advanced Biotechnology: Wood-Burning Boiler
The HN-13, part of the Herlt line, is a boiler that uses wood as its fuel. It is designed for residential and small commercial applications. This gasifier has a refractory-lined gasification chamber, surrounded by a specially packed insulating layer. This keeps heat loss and oxygen levels very low, resulting in very few inert gases, and it burns at high efficiency, the company says. This gas is delivered immediately to the combustion chamber, which works in a catalytic mode, allowing a combustion process so clean it achieves emission values that comply with standards for natural gas heating, claims the company. The chimney has a double wall lined with mineral wool that reaches 212 degrees F (100 degrees C) during use, resulting in very minimal condensation and long life expectancy, the manufacturer states. The HN-13 can handle wood logs up to 24 inches (60 centimeters) long.
