The Wood Pellets Boiler of the future

 

Types TPK 12 and
TPK 22

  - Pantented -

 

The complete unit consists of fuel tank with airtight lid for burning of wood pellets as well as a hot-water boiler.

The fuel is feeding by a worm into the combustion retort. The specially developed retort automatically regulates primary and secondary air. The is possible thanks to the oxygen control, which ensures an optimum combustion.

The fact that the unit is easy to maintain and of a sturdy, simple and robust construction maximises its durability and lowers the operating costs.

NOTE! These units is tested by the Danish Technological Institute in Aarhus.

Environmentally correct combustion with a efficiency of 92 to 93 %.

CO-emission 0,0005 vol. % at 10 % O2. Construction pressure 2,5 bar. Maximum temperature 100oC.

Control box (1x240 volt + N + E with 10 A pre-fuses) incl. of oxygen control.

The fuel box must always be closed after filling to prevent return flames.

On dimensioning the boiler room do not forget to allow for space behind the tank for filling and ample space in front of the boiler for cleaning the boiler and removing the ashes.

NOTE! The boiler can be fitted with other stoker systems and thus allow connecting of larger silos or detached fuel storages.

The photos show the combustion in the fire box according to the retort principle with underfeeding and surface combustion.

The right photo shows the fire box without extra light added which gives a better picture of the combustion principle.

NOTE: 2,2 kg wood pellets replace approx. 1 l fuel oil.
