Abstract
The utility model provides a gas-fired boiler. The shell inner cavity has a furnace chamber; the heat exchange exhaust smoke device is connected above the furnace cavity. The upper part of the inner cavity of the shell is provided with a fire collecting box; the upper part of the fire collecting box is arranged with a chimney extended out of the top end of the shell; a plurality of fire pipes are communicated with the lower part of the fire collecting box and the top end of the furnace chamber wall. The wall of the furnace chamber and the heat exchange exhaust smoke device are formed into a heated hot water sandwich which are communicated with the hot pipes are positioned in the inner wall of the furnace. The lower part of the furnace chamber is provided with a gas combustion apparatus which is evenly arranged with two circles of gas nozzles along the circumference on the plane of the annular gas disk; the internal and external circles of the gas nozzles are arranged into a divergent angle on the circumference. The two ends of the transversal connecting pipe are communicated with the inner cavity of the air disc, and one end of the air supply pipe is communicated with the central part of the connecting pipe; the other end of the air supply pipe is extended out of the shell. The gas-fired boiler has the advantages of low cost, convenient operation, safety and durability, large heating area, high efficiency, energy-saving and complete functions. The utility model is suitable to supply heating, install a bath or boil the water, etc.
Description
Technical field:
The utility model relates to a kind of boiler that acts as a fuel with fuel gas.
Background technology:
At present, the existing gas fired-boiler of China, complex structure, the manufacturing cost height, air consumption is big, and the thermal efficiency is low, is not suitable for large tracts of land popularization and utilization.
Summary of the invention:
The purpose of this utility model provides a kind of gas fired-boiler, and is simple in structure, thermal efficiency height.
The purpose of this utility model realizes as follows: in the shell inner chamber burner hearth is arranged, the burner hearth top connects the heat exchange fume extractor, form the interlayer that is heated water between hearth wall and heat exchange fume extractor and the shell, the air feed burner is housed below burner hearth, this device is the valve that circumference uniform distribution is arranged on annular gas dish, have horizontal tube connector two ends to be communicated with the inner chamber of gas dish, also have an air supply pipe one end to be communicated with at the tube connector middle part, the air supply pipe other end stretches out outside the shell.
Valve above the annular gas dish divides inside and outside two circles to distribute, and the valve of inside and outside two circles upwards diverges to angular distribution in week.
The heat exchange fume extractor is on the top of shell inner chamber fire box to be arranged, and fire box upper end has chimney to stretch out the shell top, is communicated with some fire tubes between pushing up on fire box lower end and the hearth wall.Can certainly take other mode, just can as long as can realize conducting heat and discharge flue gas.
In order to strengthen the heat exchange effect, in burner hearth, there are some hot-water line two ends that are subjected to be communicated with the boiler interlayer.
During burning, flame is above valve, and flame passes the space between the hot-water line of being subjected to of upper furnace, and the fire tube by upper furnace enters fire box, and flue gas is discharged from the chimney on top then.
This gas fired-boiler is cheap for manufacturing cost, and is easy to operate, safety durable, and heating surface area is big, and is energy-efficient, multiple functional; Being applicable to heat supply heating, founding bathing pool or boil water etc., is the desirable stove and accessory of office, school, factories and miness, enterprises and institutions' use.
Description of drawings:
Fig. 1 is the structural representation of the utility model gas fired-boiler.
Fig. 2 is that K among Fig. 1 is to view.
The specific embodiment:
With reference to Fig. 1, Fig. 2, in shell 10 inner chambers burner hearth is arranged, the burner hearth top connects the heat exchange fume extractor, and the heat exchange fume extractor is on the top of shell 10 inner chambers fire box 2 to be arranged, fire box 2 upper ends have chimney 1 to stretch out shell 10 tops, are communicated with some fire tubes 3 between the top on fire box 2 lower ends and the hearth wall 13.Form the interlayer be heated water between hearth wall 13 and heat exchange fume extractor and the shell 10, in burner hearth, have some hot-water line 12 two ends that are subjected to be communicated with the boiler interlayers, pass the lighting door 5 that interlayer is communicated with burner hearth being on the shell 10 to be subjected to have below the hot-water line 12.The air feed burner is housed below burner hearth, and it is the valve 15 that the plane has two circles to be uniformly distributed along the circumference on annular gas dish 16, and the valve 15 of inside and outside two circles diverges to angular distribution on circumference.Have horizontal tube connector two ends to be communicated with the inner chamber of gas dish 16, also have an air supply pipe 17 1 ends to be communicated with at the tube connector middle part, air supply pipe 17 other ends stretch out outside the shell 10.Shell 10 bottoms be in annular gas dish 16 below have some ventilating openings 7 that combustion air is provided.Water in the interlayer that shell 10 and hearth outer wall 13 forms is connected with heat pipe 12 and has constituted water circuit system, and fire tube 3, fire box 2 and stack extension 1 have constituted the quirk system, and gas dish 16, valve 15 and air supply pipe 17 have constituted the air feed burner.Have be communicated with the boiler interlayer various to advance the mouths of pipe such as draining gas on shell 10 with other boiler is the same: blast pipe 8 is arranged at the top, blow-off pipe 6, return pipe 14 are arranged in the bottom, there is the water pipe 4 of relieving at the middle part, advances cool water pipe 11, and feed pipe 9 is arranged on top.Return pipe 14 and feed pipe 9 are used for this stove as the external heat supply heating circulatory system of thermal source.
