Time " certain element ", the present invention does not limit the quantity of this element as one, it is also possible to include multiple.
The system schematic of one embodiment of Fig. 1 exhaust gas turbo generator group.The exhaust gas turbo generator group of Fig. 1 is general
Including turbine 12, reduction box 14, magneto 16 and inverter 18.
Turbine 12 is in order to receive waste gas to be rotated by described exhaust gas driven from exhaust gas source 10.Exhaust gas source 10 for example, piston is sent out
The tail gas that motivation 10 produces.In the case of the unequipped supercharger of electromotor 10, the tail gas that turbine 12 receives can be from starting
The exhaust valve of machine 10 directly obtains；In the case of electromotor 10 is equipped with supercharger, turbine 12 receive tail gas can be from
The air vent of supercharger obtains.
The rotation function of turbine 12 passes through the rear drive magneto 16 of reduction box 14 to generate electricity.Inverter 18 with
Magneto 16 electrically connects the electric power that magneto 16 sends is converted into required electric power.Such as, inverter 18
The electric power that the electric power that magneto 16 sends is converted into constant frequency and constant voltage is grid-connected to carry out.
By using inverter 18 to carry out electric power conversion, the turbine power generation unit of the present invention can be in engine power
Run in larger scope.As long as electromotor runs in theory, no matter full working scope or Part load, turbine power generation unit is the most permissible
Automatically sense and automatically run.The valve group equipment that will no longer be required to arrange complexity in the upstream of turbine 12 controls to pass through turbine
