Abstract
The present invention relates to a burner system for providing thermal energy comprising an evaporator device for evaporating a liquid alcohol fuel, a burner air supply means, a burner device for burning a fuel mixture comprising vaporized fuel and burner air to provide an exhaust gas stream, a functions device for controlling the thermal energy of the exhaust gas flow, wherein the burner device provides the thermal energy for evaporation in the evaporator device during operation.
Claims14
A burner system for providing thermal energy, the burner system comprising:
- an evaporator device for vaporizing a liquid fuel and providing vaporized fuel,
- a burner air supply device for providing burner air,
- a surface burner for burning a fuel mixture comprising the vaporized fuel and burner air to provide an exhaust gas stream,
- a shielding plate with openings for passing and controlling the thermal energy of the exhaust gas flow of the surface burner, wherein
- the surface burner is coupled to the evaporator device via the shielding plate in such a way that, in operation, the exhaust gas flow of the surface burner provides the thermal energy and the evaporation temperature required for complete evaporation of the fuel in the evaporator device, and
- a tertiary air supply means for supplying tertiary air to the exhaust gas stream to adjust a temperature of the exhaust gas stream by mixing with the tertiary air to form a hot gas stream.
A method of providing thermal energy, the method comprising the following steps:
- heating an evaporator device with an electrical heating device during a start-up phase,
- complete evaporation of a liquid fuel in the evaporator device,
- feeding the fully vaporized fuel to a surface burner, and
- burning the vaporized fuel in the burner device to provide thermal energy in the form of an exhaust gas stream,
- using a portion of the thermal energy to vaporize the fuel in the evaporator device during operation so that the energy for vaporization in the evaporator is provided solely by the burner device.
