K30 long time burning wooden boiler

K40 long time wooden boiler

• Power 30 kW
• Size: D 695mm x H 1750mm
• Eff. 86%
• Boiler water 70C
• Boiler water 36l
• Firewood 64 kg, Firewood lenght max 55cm.
• With one load of wood, peat and sawdust briquettes the boiler burns 6 - 30 hours 
  Exceptional characteristics of the manufactured products, which prolong the burning time of the solid fuel boiler, are the distribution of air from the top and the solid fraction burning in the candle principle. 
  The boiler is a steel cylinder covered by a steel cylinder of a bigger diameter, boiler is insulated. Heated water is between the cylinders. The boiler has doors for loading of solid fuel, ash removal and smoke extraction flue. There are also connections for water supply, thermometer and pressure safety valve. Air heating compartment for the improvement of combustion quality and heating transmission is mounted on the upper part of a combustion compartment.
• Unceasing combustion you will not have to spend more time in the boilery than necessary;
• Economical efficiency 86 %;
• The boiler operates safely.
• Boiler is self-regulated without electric device. If boiler temperature is more than setting - boiler just cuts off the air in the combustion chamber.
• Any type of wood is suitable for the fuel: firewood, sawdust briquettes, scrap of the furniture production, as well as peat briquettes and coal; 
  The firewood, timber waste, sawdust briquettes, peat turf briquettes and coal burn in the cylinder shaped mouth of the boiler. The mouth is on top; therefore not the entire loaded firewood burns intensively, but the upper part of the mouth. The firewood located in the bottom part of the boiler does not heat up and “waits for its turn” to heat up and burn. The air is distributed in such way, that the fuel would not burn up too deep. When a layer of firewood burns out, the distributor is continuously going down and always stays on the burning firewood – precisely in the combustion zone.
