A housing for a fan for supplying a fuel/oxidizer mixture to a burner, comprising:
- a housing structure having a supply opening therein;
- a fluid supply space attached to the housing and providing a fluid connection to the supply opening;
- a first supply means of a fluid-like fuel in fluid connection with the fluid supply space;
- a second supply means of an oxidizing fluid in fluid connection with the fluid supply space;
- wherein the fluid supply space comprises a mixing means for mixing the fluid-like fuel with the oxidizing fluid;
- and
- wherein the supply opening is positioned in the housing structure at an angle relative to the supply direction of the fluid in the fluid supply space.
A supply device for supplying fluid to a fan housing, comprising
- a closing part which covers a supply side of a fan housing;
- a fluid supply space attached to the closing part and providing a fluid connection to a supply opening;
- a first supply means for supplying a fluid-like fuel;
- a second supply means for supplying an oxidizing fluid;
- wherein the fluid supply space comprises a mixing means for mixing the fluid-like fuel with the oxidizing fluid;
- and
- wherein the supply opening is positioned at an angle relative to the supply direction of the fluid in the fluid supply space.
A method of supplying a fluid-like fuel with an oxidizing fluid to a fan, comprising the steps of:
- guiding the fluid-like fuel through a venturi;
- providing the oxidizing fluid flow in proximity to the venturi, whereby the oxidizing fluid is drawn in by the venturi effect and mixed with the fluid-like fuel;
- supplying the mixture of the fuel and the oxidizing fluid at an angle to a fan, which fan blows the mixture into a burner space.
A housing for a fan for supplying a fuel/oxidizer mixture to a burner, comprising:
- a housing structure having a supply opening therein;
- a fluid supply space attached to the housing and providing a fluid connection to the supply opening;
- a first supply means of a fluid-like fuel in fluid connection with the fluid supply space;
- a second supply means of an oxidizing fluid in fluid connection with the fluid supply space;
- wherein the fluid supply space comprises a mixing means for mixing the fluid-like fuel with the oxidizing fluid;
- and
- wherein at a mouth of the second supply means an obstruction extends over a part of a peripheral wall of the second supply means, the obstruction being configured to extend in a downstream direction of flow from the second supply means to the supply opening, the obstruction configured in a manner so as to impede fluid flow transversely of the first supply means and second supply means.
