Description

A kind of combustion gas steam stove

Technical field:

The utility model relates to a kind of gas furnace.

Background technology:

Existing combustion gas steam stove is by water dish, be arranged on the combustion product gases pipeline in the water dish, the air exhauster that is connected with the combustion product gases pipeline, combustion gas fire row constitutes, the combustion product gases pipeline forms with the square tube manufacturing, its shape is flexuose two stratiforms up and down, the high-temp combustion flue gas that combustion gas fire row is produced imports the combustion product gases pipeline, carry out heat exchange by the water in combustion product gases pipeline and the water dish, convert steam to after making the water heat absorption, steam carries out boiling to the food in the food steamer above the water dish.This kind combustion gas steam stove, because the combustion product gases pipeline adopts the square tube manufacturing to form, in order to promote heat exchange area, often need to adopt bigger square tube, and the shape of combustion product gases pipeline is flexuose two stratiforms up and down, like this, gap between adjacent square tube is just little, the water that is held is just few, makes the flowability in the gap of water between adjacent square tube poor, in case after the water heat absorption becomes steam, under the buffer action of steam, the heat energy of combustion product gases pipeline just is not easy to be delivered to waterborne, from having influenced heat exchanger effectiveness, and, make the combustion product gases pipeline with square tube, the suffered stress of square tube temperature distortion focuses on certain binding site place of square tube easily, this binding site is broken easily, and cause the combustion gas steam stove not work.

Summary of the invention:

Goal of the invention of the present utility model is to provide that a kind of heat exchanger effectiveness is high, well-set combustion gas steam stove.

The utility model is to realize like this, comprise the water dish that has water-level control apparatus, be arranged on the combustion product gases pipeline in the water dish, the air exhauster that is connected with the combustion product gases pipeline, combustion gas fire row, its special feature is that the combustion product gases pipeline adopts the pipe manufacturing, convex is presented at the water dish middle part, in the space of combustion gas fire ranking below last convex, the combustion product gases pipeline is connected with space below the last convex, the combustion product gases pipeline is by greatly, little two combustion product gases piping units constitute, greatly, little combustion product gases piping unit is made of two-layer or two-layer above circular flue respectively, circular up and down flue is communicated with successively, the circular flue of the superiors is connected with space below the last convex, the circular flue of orlop is connected with air exhauster, and little combustion product gases piping unit is positioned at the annulus of large-scale combustion flue unit.

Because the combustion product gases pipeline adopts the pipe manufacturing, and the combustion product gases pipeline is circular, like this, guaranteeing under the prerequisite that combustion product gases passes through smoothly, can promote the heat exchange area of combustion product gases pipeline to greatest extent, and, be not easy to form that stress is concentrated and the appearance that causes the phenomenon of the local cracking of combustion product gases pipeline.

Smooth and easy in order to connect, the both sides, middle part of convex are connected with the arc flue on the water dish, and two arc flues are connected by a flue gas straight tube with the superiors of large and small two combustion product gases piping units circular flues.Adopt the arc flue, both can increase heat exchange area, simultaneously, make the connection of combustion product gases pipeline smooth and easy.

Big in order to make, the exhanst gas outlet of little two combustion product gases piping units is in the same side, wherein the circular flue of the orlop of a combustion product gases piping unit is the annulus that has breach, the circular flue outlet in upper strata links to each other with a wherein end of annulus breach, the other end of annulus breach links to each other with air exhauster, the circular flue of the orlop of another combustion product gases piping unit is complete annulus, the circular flue outlet in upper strata links to each other with a wherein side of annulus, the opposite side of annulus links to each other with air exhauster, like this, greatly, the exhanst gas outlet of little two combustion product gases piping units is in the same side, has reduced the resistance of flow of flue gas.

The utility model compared with the prior art owing to adopt pipe to make the combustion product gases pipeline, and the combustion product gases piping unit that constitutes the combustion product gases pipeline is made of circular flue, therefore, has that heat exchanger effectiveness is high, well-set advantage.
