The combustion system simplified

Laminar Combustion

One of the main reasons why boaters and campers choose a Wallas diesel heater is safety, as the heat is generated by laminar combustion without any exposed flame. The surface temperature of the case stay low, comfortable to the touch, keeping everyone safe. The aerosols of diesel are burnt in a safe enclosed chamber and the heat generated by the forced air-fuel combustion is circulated into the indoor air. Fully enclosed burning process doesn’t leak fumes or uncomfortable odours and minimal exhaust gas is vented outside keeping the indoor air always fresh. In Wallas products, the coaxial pipe connects to a common through-hull fitting that allows both inlet air and exhaust to pass separately. This process improves efficiency, wind resistance, and lowers the power level while cooling the exhaust system.

  1. The air required for combustion is drawn into the diesel heater via inlet pipes with a 12 V fan.
  2. Then air-diesel mixture ignites and creates combustion, which takes place in a closed chamber with no exposed flame.
  3. Since diesel turns into vapor, there is only gaseous fuel.
  4. Dry heat from the combustion is blown into the indoor space through outlet pipes.
  5. Exhaust gas is safely vented outside keeping the indoor air fresh.
  6. The vapor inside the chamber burns cleanly making this technology one of the most environmentally friendly options for off-grid heating.

Wallas-Marin has done extensive testing with Neste to optimize the Wallas Greenboost burner technology for the use of fossil-free fuels and to minimise fuel consumption. The fuel pump regulates the fuel feed and the system electronics control both the fuel and air mixture to maintain an ideal clean burning process with as little fuel as possible.
