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.

A pressure-type alcohol stove includes a stove body, an upper cover, a pre-heating pipe, and an automatic liquid-feeding device, wherein the upper cover is arranged on the stove body and is matched with the stove body to form a vaporization cavity, the pre-heating pipe penetrates through the upper cover and has a bottom end located in the stove body and a top end partially stretching out of the upper cover, a pre-heating cavity is formed around the pre-heating pipe, spirally-distributed spray holes are formed through the upper cover, air jet holes used for air jetting and pre-mixing are formed through an upper part of in the pre-heating pipe.

A vehicle temperature control system, for electric motor-powered vehicles or hybrid vehicles, includes a heater (18), which can be operated electrically or/and with fuel, with a first heat exchanger device (16) for transferring heat provided in the heater (18) to a first heat carrier medium provided in a first heat carrier medium circuit (12). An operating material tank (20) holds a liquid operating material (24). A second heat exchanger device (26) provides heat transfer between the first heat carrier medium provided in the first heat carrier medium circuit (12) and energy storage material (36) contained in the operating material tank (20). A third heat exchanger device (38) provides heat transfer between the first heat carrier medium provided in the first heat carrier medium circuit (12) and a second heat carrier medium provided in a second heat carrier medium circuit (40).

Compared with traditional alcohol stoves, the alcohol stove of this invention has higher power and efficiency.

The disclosure relates to a burner having a container for storing liquid fuel, a fuel inlet for filling liquid fuel into the container, and a fire outlet for fire from burning liquid fuel to leave the burner. The fire outlet may function as fuel inlet or a separate fuel inlet is provided. The burner includes a stopping mechanism and an actuator for controlling the stopping mechanism. The stopping mechanism is displaced by the actuator towards a first position, when the temperature of the actuator is changed from a relatively high temperature to a relatively low temperature. The stopping mechanism is displaced by the actuator towards the second position, when the temperature of the actuator is changed from a relatively low temperature to a relatively high temperature. The disclosure also relates to a method of operating such a burner and a funnel for a burner.
