Hot water boiler with incline type firebox

Abstract

A hot-water boiler with an incline type firebox is proposed. In the hot-water boiler, a fire tube connector of the firebox is inclined to be deeper from an end of a firebox side to a central portion thereof, thus reducing vortices that may be generated by hot air and flames supplied from a burner.

What is claimed is: 
     
         1 . A hot-water storage type boiler with an inclined firebox, the boiler comprising:
 a housing including a housing body that defines a space therein and is open at both sides thereof, and a housing bottom part that is provided on a first side thereof and has a plurality of coupling holes;   a water tank provided in the space of the housing and supplied with direct water to store the water;   a plurality of fire tubes traversing the water tank, and coupled at first ends thereof to coupling holes of the housing bottom part;   a heating unit including a furnace provided on a second side of both sides of the housing and having on a first side of both sides of the water tank provided in the space a fire tube connector to which second ends of the fire tubes are connected, thus defining a firebox, and a burner provided to face the fire tube connector to inject air and flames into the firebox; and   an exhaust unit provided on a second side of both sides of the water tank having the heating unit, and exhausting combustion gas fed from the firebox through the fire tubes and the coupling holes of the housing bottom part and exhaust air that has undergone a heat exchange process in the fire tubes,   wherein the fire tube connector is inclined to be deeper from an outside to a central portion.   
     
     
         2 . The hot-water storage type boiler of  claim 1 , wherein the housing bottom part is inclined to be deeper from an outside to a central portion so as to correspond to the fire tube connector. 
     
     
         3 . The hot-water storage type boiler of  claim 2 , wherein the fire tubes are formed such that lengths thereof are reduced from the outside to the central portion depending on an inclination of the fire tube connector. 
     
     
         4 . The hot-water storage type boiler of  claim 2 , wherein the central portion of the fire tube connector is formed to be horizontal in a predetermined area. 
     
     
         5 . The hot-water storage type boiler of  claim 2 , wherein the fire tube connector is formed to have any one of a circular shape, a square shape, a hexagonal shape, and an octagonal shape, depending on a shape of the housing, and
 the central portion is of any shape to maintain the inclination.   
     
     
         6 . The hot-water storage type boiler of  claim 2 , wherein the housing is opened at upper and lower portions thereof,
 the furnace is provided on the upper portion of the housing so that the firebox faces upwards, and   the burner is provided on an upper portion of the furnace to spray the flames and the air towards the fire tube connector of the furnace.
