Abstract

The utility model relates to a vapor and water two purpose boiler. The utility model has the essential structure that a boiler furnace is arranged on the top part of a combustion chamber, and is abutted on the combustion chamber; the bottom of the boiler furnace is in a hemisphere shape; a smoke channel is formed by the outer wall of the boiler furnace and the inner wall of an annular water jacket; the boiler furnace and the annular water jacket are mutually separated; the annular water jacket is directly communicated with an annular water tank on the upper side wall of the combustion chamber, and water in the annular water jacket is directly contacted with the wall of the combustion chamber. The utility model has the advantages of simple structure, low cost, quick ignition, and high heat efficiency. The utility model not only can be used for heating and supplying drinking water, and can also generate the steam. The utility model is suitable for being used in bakeries and small-size breweries.

Description

A kind of vapour, water boiler for dual purpose

The utility model belongs to a kind of vapour, water boiler for dual purpose, and this boiler has the combustion chamber, the combustion chamber have air vent and and the inwall of boiler body between form ventilating duct, this ventilating duct lower end communicates with air door.

Existing vapour, water boiler for dual purpose are segmentation to carry out, its basic structure is to have a combustion chamber that has air vent, form ventilating duct between the inwall of this combustion chamber and boiler body, the top of combustion chamber has some transverse tubes or vertical tube, and the boiler hypomere is used for heating, and the stage casing produces steam, epimere produces waste heat, isolate mutually between each section, the vapour of this structure, water boiler for dual purpose, complex structure, poor thermal efficiency, coal consumption are big, and the instability of steaming and manipulation strength are big.

The purpose of this utility model is to avoid the vapour that weak point provides a kind of simple in structure, with low cost, the thermal efficiency is high, the water boiler for dual purpose of above-mentioned prior art, and this boiler economizes coal, saves time, laborsaving, easy to operate and free from environmental pollution.

The purpose of this utility model can reach by following measure; Upper side wall in the combustion chamber has annular water tank, this annular water tank directly connects with ring-shaped water jacket, makes that water directly contacts with chamber wall in the ring-shaped water jacket, and one side has improved the thermal efficiency, reduce the temperature of combustion chamber on the other hand, improved the service life of combustion chamber.

The purpose of this utility model also can be expressed by following measure; Top in the combustion chamber has flue, and said flue hangs in the boiler, is separated near combustion chamber and boiler ring-shaped water jacket.The outer wall of flue and the inwall of ring-shaped water jacket are formed flue, have increased the heating surface area of flue and ring-shaped water jacket.

Said combustion chamber is made by the metallic plate welding.

The utility model compared with prior art has fast, advantage such as aerogenesis is fast simple in structure, with low cost, on fire, particularly because flue places top of combustion chamber near the combustion chamber, and the inwall of furnace outer wall and ring-shaped water jacket is formed flue, increased the heating surface area of flue, and, the upper, annular tank of ring-shaped water jacket and outer wall of combustion chamber connects, the interior water of chamber wall and water jacket is directly contacted, effectively raise the thermal efficiency, reduce the temperature of chamber wall simultaneously, improved the service life of combustion chamber.

Accompanying drawing and drawing are described as follows:

Accompanying drawing is a structural profile schematic diagram of the present utility model:

Below in conjunction with accompanying drawing the utility model is further described:

With reference to accompanying drawing, combustion chamber (15) is got some air vents (16) in advance, be welded into cylindric by metallic plate, has ventilating duct (18) between combustion chamber and boiler body inwall, this ventilating duct lower end communicates with air door (19), the top welding of top and combustion chamber is fixing, the upper side wall of (15) has annular water tank (22) in the combustion chamber, this annular water tank directly and ring-shaped water jacket (20) connect, water in the ring-shaped water jacket (20) is directly contacted with chamber wall, flue (8) structurally is separated from each other with boiler body, with the direct-connected blowdown flange of flue (8) (9), water level silk head (12), hot water silk head (7), wireway (4) directly passes boiler ring-shaped water jacket (20) respectively, make flue (8) not connected with the water route of body of heater, simultaneously, also make flue (8) be fixed in center in the body of heater, flue (8) bottom design becomes hemispherical, the top that places combustion chamber (15) is near the combustion chamber, the inwall of its outer wall and boiler body (6) has been formed flue (13), increased the heating surface area of flue (8) and ring-shaped water jacket (20), hot water in the flue (8) can be discharged by hot water silk head (7), the water level meter is installed on the water level silk head (12), be used to observe the flue water level, when lack of water, can add water by adding water silk head (21), the steam of output is discharged by wireway (4) organizine head (3).

The inwall of boiler (6) is formed ring-shaped water jacket (20) with outer wall (5), boiler top impact tube (2) welds and fixes with chimney flange (1) with boiler inner wall (6), outer wall (5), the heating water is discharged by water outlet silk head (11), enter in the water jacket (20) by backwater silk head (14), has blowdown flange (10) at boiler bottom, when not needing to warm oneself, can flue (8) and ring-shaped water jacket (20) be interconnected, be used to produce steam jointly by being communicated with silk head (17).

The utility model also can remove flue (8).The top of (15) changes transverse tube or vertical tube structure into and connects with ring-shaped water jacket (20) in the combustion chamber, forms single heating boiler.
