Embodiment 1

[0057] Such as figure 1 Shown is the independent dual-power steam turbine and fuel engine schematic diagram of the present invention

[0058] The heat exchanger 2 is arranged outside the exhaust manifold 3 of the fuel engine 1 , and absorbing exhaust heat will heat the water 19 inside the heat exchanger 2 to generate high-pressure steam 20 . The steam outlet 4 of the heat exchanger is connected to the steam inlet 7 of the steam turbine, and the high-pressure steam 20 passes through the steam outlet 4 of the exchanger to input the high-pressure steam 20 to the steam turbine 8 to drive the steam turbine 8 to rotate. The exhaust port 5 of the fuel engine is connected to the tail gas inlet 6 of the steam turbine, and the exhaust gas of the fuel engine is input to the steam turbine 8 to drive the steam turbine 8 to rotate. The two gases simultaneously drive the steam turbine 8 to rotate to form a dual-power steam turbine. The two mixed gases are exhausted into the atmosphere throu...

Embodiment 2

[0061] Such as figure 2 Shown is a schematic diagram of a dual power steam turbine and fuel engine with water tank and air receiver

[0062] Embodiment 2 adds a water tank 12 and an air storage tank 13 on the basis of Embodiment 1. The water tank 12 and the heat exchanger 2 are communicated through the heat exchanger replenishment control valve 21 to replenish water for the heat exchanger to ensure that there is an appropriate amount of water inside the heat exchanger to generate enough steam. The filling valve is automatically controlled or manually controlled. The steam outlet 4 of the heat exchanger is connected to the gas storage tank 13, and the generated high-pressure steam is stored in the gas storage tank 13 through the gas outlet. The high-pressure steam is output to the steam inlet 7 of the steam turbine through the gas flow controller 14, and is controlled by the gas flow controller 14 to drive the turbine to rotate; the water tank 13 is provided with a water tan...

Embodiment 3

[0064] Such as image 3 Shown is a schematic diagram of a steam turbine as a turbocharger

[0065] Embodiment 3 is a fuel engine with a turbocharger. The steam and exhaust gas simultaneously drive the turbocharger through the exhaust gas inlet 6 and the steam inlet 7 of the turbine, which greatly increases the output flow and pressure of the supercharger. Provides more air to the engine for combustion. The mixed exhaust gas is mixed and discharged through the exhaust gas outlet 9. Effectively improve engine efficiency, save fuel and reduce emission pollution.

Abstract

The invention provides a dual-power steam turbine. The steam turbine is composed of a steam turbine body and a fuel engine; a heat exchanger is arranged at any part of a shell or a divided manifold orthe outside of a cylinder or a tail gas outlet of the fuel engine, and converts waste heat of the engine into high-pressure steam; an air inlet of the steam turbine body is connected with a high-pressure steam outlet of the heat exchanger and an air exhaust port of the fuel engine to form the dual-power steam turbine. The heat efficiency of the fuel engine is improved by 60% or above, fuel oil issaved by 20% or above, and the tail gas emission pollution is reduced by 60% or above. The dual-power steam turbine is applicable to both ground engines and sea and air engines; the problems that thefuel engine is low in efficiency and high in oil consumption and heavily pollutes the environment are solved fundamentally; the fuel engine saves energy and protects the environment.

Description

technical field [0001] The invention belongs to the technical field of fuel engines, in particular to a dual-power steam turbine. Background technique [0002] Existing fuel engines include fuel engines and gas engines, which can be divided into deflagration-driven and airflow-driven engines. Deflagration-driven engines are mainly piston engines and rotary engines. Airflow driven engines are mainly gas turbines and steam turbines. Existing steam turbines are driven by gas or steam single gas. [0003] Its weak point is: the deflagration-driven motor has only utilized the pressure of fuel deflagration to drive the motor. A large amount of heat is discharged without doing work, the efficiency is very low, waste and pollution are serious. [0004] Gas turbines only use the high-speed airflow generated by the combustion of fuel to drive the engine to rotate. The pressure and heat of fuel deflagration are underutilized. A large amount of heat is discharged without doing wor...
