The utility model discloses a fire tube barrel, including firetube and staving, the firetube has four, and the firetube erects the top of installing at the staving, the inlet port support is installed to the bottom upper end of staving, the venthole support is installed to the bottom below of staving, and the firetube is the shape of four "N" intercommunications, four the second inlet port on the firetube is linked together, four with the first inlet port on the inlet port support four second ventholes on the venthole support are connected to first venthole on the firetube correspondence respectively. This fire tube bucket through four vertical firetubes of installation in the staving, because every firetube all is by the shape of four "N" intercommunications, compares the straight tube of installation in the staving in the past, makes firetube pipeline length extension, and heating area increases, has accelerated the rate of heating of staving and four firetube jacket normal water like this, has reduced the heat loss.

Description

Fire tube barrel

Technical Field

The utility model relates to a firetube bucket technical field specifically is a firetube bucket.

Background

Fire tube boilers are also known as shell boilers. The basic structure is that a small cylinder, a pipe (called as a fire tube) or a shell (called as a furnace pipe) in other shapes is arranged in a large cylinder (a boiler shell), the fire tube is isolated from the large cylinder and forms a jacket, water is contained in the jacket, the fire tube and the furnace pipe are used as a combustion chamber and a flue to contain flame or smoke, and heat generated by combustion or brought by the smoke is transferred to the water through the wall of the fire tube. The fire tubes in existing fire tube barrels are generally straight tubes, which causes the water to heat up slowly and the heat to be lost quickly. It is desirable to provide a fire tube barrel that solves the above problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a fire tube bucket to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a fire tube barrel, includes firetube and staving, the firetube has four, and the firetube erects and installs at the top of staving, the inlet port support is installed to the bottom upper end of staving, the venthole support is installed to the bottom below of staving, the firetube includes the fire pipeline, and the firetube is the shape of four "N" intercommunications, the firetube is close to inlet port support end and is equipped with the second inlet port, the firetube is close to venthole support end and is equipped with first venthole, the inlet port support is equipped with a first inlet port, it has four second ventholes to open on the venthole support, four second inlet port on the firetube is linked together with the first inlet port on the inlet port support, four first venthole on the firetube corresponds four second ventholes on the venthole support of connection respectively.

Preferably, waist-shaped mounting holes are formed in four angular positions of the air inlet hole support and the air outlet hole support.

Preferably, the diameters of the first air inlet hole, the second air inlet hole, the first air outlet hole and the second air outlet hole are the same.

Compared with the prior art, the beneficial effects of the utility model are that: this fire tube bucket through four vertical firetubes of installation in the staving, because every firetube all is by the shape of four "N" intercommunications, compares the straight tube of installation in the staving in the past, makes firetube pipeline length extension, and heating area increases for the heating rate of staving and four firetubes jacket normal water like this, has reduced the heat and has run off, is fit for using widely.
