Problems solved by technology

[0003] However, the structural principle of the existing gas and oil-fired boilers is that the fuel is mixed with the air and burns at the moment when the fuel is sprayed from the nozzle. Due to the short mixing time and insufficient mixing, the fuel cannot be fully utilized and the thermal efficiency is not high.

Embodiment approach

[0025] In one embodiment of the present invention, a plurality of water tube fin combinations includes at least one first water tube fin group, and the water pipes 9 in the first water tube fin group are connected sequentially through fins 10, such as figure 2 Shown the water pipe 9 of even row.

[0026] In another embodiment of the present invention, the plurality of water tube fin combinations further includes at least one second water tube fin group, the water pipes 9 in the second water tube fin group are sequentially connected by fins 10, and the second water tube fin group One of the water pipes 9 in the sheet group is also connected with the inner wall of the liner 2 through fins 10, as figure 2 Shown the water pipe 9 of odd row.

[0027] For the balance of the arrangement of the water pipes 9 and the fins 10 in the liner 3, the water pipes 9 in the same water pipe fin combination are equally spaced, and the first water pipe fin group and the second water pipe fin gr...

Abstract

The invention discloses a gas-fired boiler. The gas-fired boiler comprises a boiler body, an inner container arranged in the boiler body and a burner, a fume discharging pipe is connected to the upperend of the inner container, a gas input pipe, a water inlet and a water outlet are connected to the outer wall of the boiler body, the gas input pipe is communicated with the burner, an interlayer which is communicated with the water inlet and the water outlet is arranged between the inner wall and the inner container of the boiler body, the inner container is internally provided with multiple passage tubes in the horizontal direction, the two ends of each passage tube penetrate through the side wall of the inner container separately to be communicated with the interlayer, and fins used for cooling are connected to one side or two sides of each passage tube. Accordingly, by increasing the flow path of water in the boiler body, increasing the path length of flue gas in the boiler body andadditionally arranging the fins to achieve guidance on run of the flue gas, sufficient burning is achieved, the heat utilization ratio is increased, and the heating efficiency of the boiler is improved.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a gas boiler. Background technique [0002] As the requirements for environmental protection become higher and higher, coal-fired boilers are gradually replaced by gas and oil-fired boilers. But whether it is a gas or oil-fired boiler, the more fully the fuel and air are mixed during combustion, the higher the thermal efficiency can be obtained, and at the same time reduce exhaust emissions and reduce environmental pollution. [0003] However, the structural principle of the existing gas and oil-fired boilers is that the fuel is mixed with the air and burns at the moment when the fuel is sprayed from the nozzle. Due to the short mixing time and insufficient mixing, the fuel cannot be fully utilized and the thermal efficiency is not high. . Contents of the invention [0004] The present invention proposes a gas boiler to solve the above technical problems. [0005] In order t...
