Boiler with flat horizontal tubes

Abstract

The present invention relates to a boiler having horizontally arranged flat rectangular water tubes comprising: a water chamber; an inner water chamber to be connected with horizontal water tubes, said horizontally arranged water tubes forming multi-step water tube groups; induction plates provided in the inner water chamber blocking the water path of the horizontal water tubes alternatingly in such a manner as to bend the water path in a zigzag manner; an exhaust gas discharge conduit in straight lattice lines formed by narrow gaps between the horizontal water tubes; and an exhaust gas discharge chamber formed in an upper water chamber. The flat horizontally arranged rectangular water tubes are narrow in their width, making it possible to arrange them densely in the limited space of the combustion chamber, and with their increased heat receiving areas, the water tubes can heat the water in the boiler fast.

1 . A boiler with flat horizontal water tubes comprising:
 a water chamber ( 2 ) formed along the inside walls of the body ( 1 ) of the boiler;   an inner water chamber ( 2   a ) with partitions ( 4   a ) formed interior to the front and rear sides of said water chamber ( 2 ), said inner water chamber ( 2   a ) being separated from said water chamber ( 2 ) by inner walls ( 4 ) of the water chamber ( 2 ), said water chamber ( 2 ) and said inner water chamber ( 2   a ) communicating through holes ( 2   h ) with a lower water chamber ( 2   c ) formed around a combustion chamber ( 5 );   a multiplicity of flat horizontal water tubes ( 3 ) arranged densely left and right, top and bottom, said water tubes ( 3 ) forming multiple steps of water tube groups ( 3 A) top and bottom, both ends of said water tubes ( 3 ) being connected with partitions ( 4   a ) in such a manner as to communicate with an upper water chamber ( 2   b );   induction plates ( 4   c ) provided in the inner water chamber ( 2   a ) in such a manner as to block the water path ( 3   r ) of the water tube groups ( 3 A) alternately to induce the water path ( 3   r ) in a zigzag manner by providing the induction plates ( 4   c ) at both end portions of the water tube groups ( 3 A) with alternatingly different heights;   an exhaust gas discharge conduit ( 5   a ) formed by narrow gaps between the horizontal water tubes ( 3 ) arranged in the space of the combustion chamber ( 5 ) in such a manner as to communicate with an exhaust gas discharge chamber ( 5   c ) for the exhaust gas to be discharged through an exhaust gas outlet ( 5   b ) and a chimney ( 5   d ).   
   
   
       2 . A boiler with flat horizontal water tubes as in  claim 1 , in which the water tube groups ( 3 A) are arranged in such a manner that the horizontal water tubes ( 3 ) are densely arranged with the wider width (b) of the horizontal water tube at its side and the narrower width (a) of the horizontal water tube ( 3 ) at its top, and in which the water tube group ( 3 A n ) in the uppermost step is arranged with the wider width (b) of the horizontal water tube ( 3 ) at its top and the narrower width (a) of the horizontal water tube ( 3 ) at its side.
