Abstract

The utility model relates to a top-fired steam and boiling water boiler, comprising a boiler shell, an upper and a lower boiler chambers, a smoke chamber provided with a transverse water pipe and a dust cleaning hand hole, a water cavity and a smoke pipe set composed of 25 to 35 smoke pipes. The utility model overcomes the defects that the prior art uses a pipe with large diameter and is provided with the smoke pipe set with the number less than ten, and the smoke chamber is not provided with the dust cleaning hand whole causing small heat-exchange surface and hard cleanness of the dust in the smoke chamber, and has the advantages that the heat-exchange area of the smoke pipe is increased doubly, the heat efficiency is high, the dust is cleaned easily from the smoke chamber, etc.

Description

Counter-burning type steam, boiling water boiler for dual purpose

The utility model belongs to a kind of counter-burning type boiler, particularly a kind ofly both can provide steam, and the normal pressure counter-burning type boiler of boiling water can be provided again.This boiler can be little brewery steam usefulness is provided, and also can be used as boiler for domestic and uses.

At application number is that the inventor discloses a kind of steam, boiling water boiler for dual purpose in 99232592.7 the patent documentation, it comprises the upper and lower burner hearth of furnace shell, band fire door and is positioned between the two water-cooled grate tube, the smoke chamber of band horizontal water tube and the built-in fume pipe group that this smoke chamber is communicated with lower hearth, water cavity between furnace shell and upper and lower burner hearth and smoke chamber is located at the hawk of lower hearth bottom and is located at the chimney at boiler top.Though this boiler has overcome the defective of traditional external high-temperature flue counter-burning type boiler, but because the fume pipe that is adopted is the major diameter fume pipe and generally only is provided with below 10, thereby there is postpone in the fume pipe again, entering the smoke chamber temperature reduces, in smoke chamber, be difficult to form second-time burning, and because fume pipe is provided with less, its heat-transfer surface is corresponding less under the condition of same airflow sectional area, heat exchanger effectiveness is also just lower, thereby has influenced the defectives such as further raising of boiler efficiency and air demand.

The purpose of this utility model is at the existing defective of background technology, design a kind of counter-burning type steam, boiling water boiler for dual purpose that adopts the small-bore built-in fume pipe of multitube, to reach the heat exchange area that increases fume pipe, improve purposes such as the thermal efficiency and smoke chamber deashing convenience.

Solution of the present utility model is the diameter that reduces fume pipe, and the amount of setting of the fume pipe that is multiplied simultaneously is to increase the heat exchange area of fume pipe; Set up a hand hole so that remove the cigarette ash that deposits in the smoke chamber at smoke chamber.Thereby realize its purpose.Therefore, the utility model comprises furnace shell, the upper and lower burner hearth of band fire door and be positioned between the two water-cooled grate tube, the smoke chamber of band horizontal water tube and the built-in fume pipe group that this smoke chamber is communicated with lower hearth, water cavity between furnace shell and upper and lower burner hearth and smoke chamber, be located at the hawk and the air intlet of burner hearth bottom, be positioned at the chimney at boiler top; Key is that it is the fume pipe of Φ 60～75mm that the fume pipe group that smoke chamber is communicated with lower hearth adopts two row's diameters, and its quantity is generally 25～35; Each fume pipe divides upper and lower two rows to be spaced, and strikes up partnership with lower hearth and smoke chamber weldering respectively.For the ease of the smoke chamber deashing, on smoke chamber, also offer a deashing hand hole.

The utility model is owing to adopt the diameter that reduces the high-temperature flue gas pipe, and the amount of setting that is multiplied is to increase its heat exchange area, and its heat exchange area doubles above than background technology; And on smoke chamber, set up the deashing hand hole, to make things convenient for the smoke chamber deashing.Characteristics such as therefore, it is big to the utlity model has fume pipe group heat exchange area, and the thermal efficiency is higher, and the smoke chamber deashing is convenient.
