Main Features of Kyu Won Tech's[Hybrid Fuel Wood Boiler]

Two combustors in one boiler Both wood and waste wood can be used with oil. Since two separate combustors lie in one boiler, there is no worry about the declination of heat exchange capability due to soot. It has 3 functions to work : wood, wood/oil and oil

Convenient automated control Since it is automatically controlled on overheating, freezing and low level of fuel, it is safer than other boilers. In addition, automatic raptor controls air volume through water temperature sensor in the boiler, so that firewood placed in the boiler combusts slowly and thus saves fuel. It is very convenient because it doesn't require man guarding around it.

Highly efficient boiler It adopts 3-round combustion system into heat exchanger, so there is little of heat that leaks through fuel tank. Therefore, it is more thermally efficient than other wood-fueled boilers.

Wide inlet of fuel wood and combusting room Since it has wide opening for fuel wood and combusting room, it can avoid hassle of placing fuel often.

Reduction of fuel-cost by the use of various fuels It can use various kinds of fuels including general wood. Therefore, it is the most suitable for farming facilities.
