Small-scale combined heat and power generator using steam injector

Abstract

The present invention relates to a small-scale combined heat and power generator using a steam injector with a small-scale heat source and, more particularly, to a small-scale combined heat and power generator in which, since reaction energy of a steam injection force from nozzles (106) of a rotatable disk-shaped steam injector, which has a plurality of nozzles configured to inject steam mounted thereon, is applied to the disk-shaped steam injector and then action energy of the injected steam which returns to a steam injection plate (107) adjacent thereto by performing a U-turn after colliding with a steam reflection inducing groove (108) installed to reflect the injected steam is also applied to the disk-shaped steam injector, a rotational force of the steam injector configured to generate power is doubled without a turbine.

1 . A small-scale combined heat and power generator ( 10 ) using a small-scale heat source, comprising:
 a steam introduction pipe ( 102 ) into which steam is introduced;   a disk-shaped steam injector body ( 104 ) rotatably installed on an end portion of the steam introduction pipe through a steam leakage prevention bearing assembly;   a steam injection nozzle ( 106 ) mounted on an end portion of a steam injection path ( 105 ) connected to an outer circumferential surface of the body;   a circular steam injection plate ( 107 ) mounted adjacent to the steam injection nozzle;   a steam reflection inducing groove ( 108 ) installed to reflect steam injected onto the steam injection plate;   a power generator ( 109 ) configured to generate power; and   a heat exchanger ( 110 ) configured to produce hot water,   wherein since reaction energy of a steam injection force from the nozzles ( 106 ) of a disk-shaped steam injector, which has a plurality of steam injection nozzles mounted thereon, is applied to the disk-shaped steam injector and then action energy of the injected steam which returns by performing a U-turn after colliding with the steam reflection inducing groove ( 108 ) of the steam injection plate ( 107 ) adjacent thereto is also applied to the disk-shaped steam injector, a rotational force of the steam injector is doubled in a power generating system without a separate turbine.   
     
     
         2 . The small-scale combined heat and power generator of  claim 1 , wherein at least one steam leakage prevention steel plate shield ( 103   e ) and at least one steam leakage prevention ring ( 103   f ) are each installed in plural in a steam leakage prevention bearing assembly ( 103 ) of the small-scale combined heat and power generator. 
     
     
         3 . The small-scale combined heat and power generator of  claim 1 , wherein the steam injection path ( 105 ) of the steam injector is elongated and a diameter of the steam injector increases to secure the rotational force. 
     
     
         4 . The small-scale combined heat and power generator of  claim 1 , wherein at least one disk-shaped steam injector is horizontally installed in the small-scale combined heat and power generator in plural. 
     
     
         5 . The small-scale combined heat and power generator of  claim 1 , wherein the steam injection path of the steam injector is streamlined to reduce air resistance.
