General description:
We are introducing you the ecological wood gasification boiler of the output 18, 25, 40, 60,
80kW. The hot-water boiler is designed for heating of apartment, family house, guest house,
smaller industrial workshop and similar object
.
The boiler is designed for burning of wood only.
Any dry wood can be used for burning, mainly logs till 550-1000 mm length. Also wood of higher
humidity can be used but then the nominal output is reduced and burning time prolonged. Due to
its large feed hopper you can avoid the most demandable operation of preparation and cutting the
wood into smaller pieces. It’s recommended to feed fire with logs of approx. diameter 10-15 cm.
The ashes is only 1-2 % from amount of used wood (cleaning approx. once a week maximum) In
consideration of very low level harmfull pollutants production the operation of wood gasification
boiler is very ecological.
Wood gasification boilers are well-tested and easy to use. The boiler is produced from the special
boiler sheet steel of thickness – 6 mm inner part and 4mm outer part. Fireproof shaped pieces
inside the boiler are made from a special heatproof material, so the pieces are highly heat resistant,
high strength and provide long service life. The body of the boiler is made as weldment of steel
plates. It includes a feed hopper with a heatproof shaped piece that has an oblong opening (nozzle)
for transit of flue gas. Under the nozzle there is a combustion space formed with the ceramic
shaped pieces. In the rear part of the boiler there are vertical flue tubes which in the upper part go
to the collecting channel with a make fire flap. Rear part of the collecting channel is fitted with an
eduction pipe for connecting to the chimney. In the front of boiler is situated a
blowing ventilator
with regulation flap for air inlet. The boiler body is insulated by mineral wool Nobasil of
thickness 20mm which is located between the body and jacketing.
Primary and secondary air is preheated and in optimal ratio distributed into the combustion
chamber and nozzle.
Wood gasification boilers are completely different from the current solid fuel boilers. The priciple
of burning is based on the gasification at high temperature (approx. 1100 °C).
Wood burning gas is supported by a
blowing ventilator
which blows primary air into the
combustion chamber and secondary air injection into the nozzle. This combustion system is very
economical while saving approx. 40% of fuel. Boiler operation requires the minimum attendance
due to automatic operation of the boiler. Hopper contents is sufficient for about 8 to 12 hours
operation at medium power. At minimum output level the boiler is operational even up to 24
hours. All this provides the digital microprocessor control measures.
