Abstract

A finned boiler is characterized in that at the part, in direct contact with flame, of a boiler body, fin ribs are welded to the outer surface or fin ribs are welded to the inner surface or fin ribs are welded to both the inner and outer surfaces, the fin ribs are radially annular, or axially bar-like, or both radially annular and axially bar-like, the fin ribs are equal or unequal in height, and the fin ribs are equal or unequal in thickness. The finned boiler is efficient, energy saving, environmentally friendly and longer in service life.

Description

Fin boiler

Technical field

The invention belongs to field of boilers.

Background technology

Prior art is to take the boiler that natural gas or liquefied gas or fuel oil or coal bed gas or coal or biogas etc. be fuel, boiler is in combustion heating process, the boiler body directly contacting with flame can produce the phenomenon of burning, melting pot furnace body, infringement boiler body, reduction of service life.

Summary of the invention

A kind of fin boiler, the position that boiler body directly contacts with flame, inside and outside surface soldered fin muscle sheet, strengthens boiler body rigidity, external heating surface upper rib increases heating surface area, improve boiler body regenerative capacity, reduce and reduce boiler body burning, fusing produces, prolonged boiler service life, inner surface upper rib increases heat transfer area, improve boiler heat storage capacity, improve heat transfer rate and heat transfer efficiency, energy-saving and emission-reduction.The scheme of specifically dealing with problems: a kind of fin boiler, the position that boiler body directly contacts with flame, outer surface welding fin muscle sheet or inner surface welding fin muscle sheet or surfaces externally and internally all weld fin muscle sheet, described fin muscle sheet is that annular radial or axial strip or annular radial and axial strip have, described fin muscle sheet is contour or not equal altitude, described fin muscle sheet be equal thickness or thickness not etc.Advantage of the present invention: efficient, energy-conservation, environmental protection.

Accompanying drawing explanation

Fig. 1 is the primary structure schematic diagram of fin boiler, the 1st, and boiler body, the 2nd, muscle sheet, the 3rd, heating burning things which may cause a fire disaster.

The specific embodiment

A kind of fin boiler, the position that boiler body directly contacts with flame, outer surface welding fin muscle sheet or inner surface welding fin muscle sheet or surfaces externally and internally all weld fin muscle sheet, described fin muscle sheet is that annular radial or axial strip or annular radial and axial strip have, described fin muscle sheet is contour or not equal altitude, described fin muscle sheet be equal thickness or thickness not etc.

Claims (3)

1. a fin boiler, is characterized in that: the position that boiler body directly contacts with flame, outer surface welding fin muscle sheet or inner surface welding fin muscle sheet or surfaces externally and internally all weld fin muscle sheet.

2. fin boiler according to claim 1, is characterized in that: described fin muscle sheet is that annular radial or axial strip or annular radial and axial strip have.

3. fin boiler according to claim 1, is characterized in that: described fin muscle sheet is contour or not equal altitude, described fin muscle sheet be equal thickness or thickness not etc.
