Abstract
The utility model discloses a gas type water boiler, which comprises an upper inner container and a lower inner container, a flue is disposed between the upper inner container and the lower inner container, a first fire tube is arranged inside the lower inner container, a second fire tube is arranged inside the upper inner container, the upper end of the first fire tube is communicated with the flue, and the lower end of the second fire tube is communicated with the flue. After hot gas from the first fire tube is mixed in the flue, the hot gas enters a second flue to preheat water inside the upper inner container. Therefore, the gas type water boiler has the advantages of improving heat utilization ratio and reducing flue gas temperature.
Description
Technical field
The utility model relates to a kind of gas burning water heater.
Background technology
Gas heater is to utilize combustion gas fast water to be heated boiled equipment, is widely used in fields such as hotel, office building, kitchen.Gas heater comprises support, inner bag, heater, fire tube, and inner bag is arranged in the support, and the support of inner bag bottom is provided with heater, is provided with fire tube in the inner bag, and fire tube is brought the heat of heater in the inner bag into.
Present gas heater all is divided into inner bag upper inner-liner and bottom inner container, isolate by flue between the last bottom inner container, be equipped with fire tube in upper inner-liner and the bottom inner container, present fire tube is different in size, the fire tube layout from bottom to top, again by last around down, or fire tube carries out the levels coiling, be unfavorable for the convection current of water, every fire tube exhaust gas temperature differs, and upper strata fire tube exhaust gas temperature is higher.
The utility model content
The purpose of this utility model is to provide a kind of gas burning water heater, and it is higher effectively to solve present upper strata fire tube exhaust gas temperature, the problem that heat utilization efficiency is lower.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of gas burning water heater, comprise upper inner-liner and bottom inner container, be provided with flue between described upper inner-liner and the bottom inner container, be provided with first fire tube in the described bottom inner container, be provided with second fire tube in the described upper inner-liner, the upper end of described first fire tube communicates with flue, and the lower end of described second fire tube communicates with flue.
Preferably, described first fire tube is a S shape pipeline; Increase contact area.
Preferably, described first fire tube is formed at least two end to end S shape pipelines; Need plural S shape pipeline to form to jumbo bottom inner container, the water in the bottom inner container is fully heated.
Preferably, described second fire tube is a straight tube.
Preferably, described second fire tube comprises at least two straight tubes, and the lower end of above-mentioned straight tube communicates with flue, and upper inner-liner is passed in the upper end of above-mentioned straight tube.
Preferably, the cross section of described first fire tube, second fire tube is circle; Further increase contact area with water.
Compared with prior art, the utility model has the advantages that: enter second flue after the hot gas that first fire tube is come out mixes in flue the water in the upper inner-liner is carried out preheating, improved heat utilization efficiency, reduced exhaust gas temperature.
Description of drawings
Fig. 1 is the structural representation of a kind of gas burning water heater of the utility model.
The specific embodiment
Consult the embodiment of Fig. 1 for a kind of gas burning water heater of the utility model, a kind of gas burning water heater, comprise upper inner-liner 1 and bottom inner container 2, be provided with flue 3 between described upper inner-liner 1 and the bottom inner container 2, be provided with first fire tube 4 in the described bottom inner container 2, be provided with second fire tube 5 in the described upper inner-liner 1, the upper end of described first fire tube 4 communicates with flue 3, the lower end of described second fire tube 5 communicates with flue 3, described first fire tube 4 is that S shape pipeline or at least two end to end S shape pipelines are formed, described second fire tube 5 is straight tube or at least two straight tubes, the lower end of above-mentioned straight tube communicates with flue 3, upper inner-liner 1 is passed in the upper end of above-mentioned straight tube, described first fire tube 4, the cross section of second fire tube 5 is circle.
Can adopt the first parallel fire tube 4 of many rows in the bottom inner container 2, the water of bottom inner container 2 and first fire tube, 4 contacts area are big, water to bottom inner container 2 evenly heats, the hot-air that flows out from first fire tube 4 enters flue 3 and enters second fire tube 5 then, make the tail heat in second fire tube, 5 collecting flues 3 carry out preheating to the water of upper inner-liner 1, final exhaust gas temperature reduces greatly, has higher heat utilization efficiency.
The above only is a specific embodiment of the utility model, but technical characterictic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the claim of the present utility model.
