The device has an injector (2) supplying a combustible gaseous mixture e.g. air and natural gas mixture, to a cylindrical chamber, where the chamber has an outer peripheral heat surface (10). An injector (4) supplies a combustible gaseous mixture to a hollow and cylindrical chamber that is placed inside the cylindrical chamber, where the hollow and cylindrical chamber has an internal heat surface (30). The injectors supply the gaseous mixture to the chambers, where the chambers are separated and independent from one another. |
