Abstract
The utility model relates to a boiler, in particular to a gas-fired boiler, comprising a furnace body and a hearth arranged in the furnace body, the hearth is communicated with an intake pipe, a combustion chamber is arranged on the outer side of the hearth, a gas through hole arranged at the lower end of the hearth is communicated with the lower end of the hearth, and the upper end of the combustion chamber is connected with an exhaust pipe; the intake pipe extends into the hearth from the lower end of the hearth, the top of the intake pipe is higher than the gas through hole and lower than the top of the hearth. The utility model has the advantages of low heat dissipation and high thermal efficiency; meanwhile the utility model avoids burning up the intake pipe and the hearth because of no open fire burning in the hearth, and extends the service life.
Description
Technical field
The utility model relates to a kind of boiler, is a kind of gas fired-boiler specifically.
Background technology
Gas fired-boiler is to utilize fuel gas and air mixing after-combustion, adds a kind of device of hot water.Common gas fired-boiler mostly makes fuel gas directly burn in burner hearth, gas undercompounding, the burning not thorough, the thermal efficiency is low, also burns out burner easily.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, thermal efficiency height, the gas fired-boiler of long service life.
For achieving the above object, the utility model adopts following technical scheme:
Gas fired-boiler described in the utility model comprises body of heater, is arranged on the burner hearth of body of heater inside, and burner hearth communicates with air inlet pipe, and the outside of burner hearth has the combustion chamber, and the lower end of combustion chamber has the combustion gas through hole to be communicated with the lower end of burner hearth, and the upper end of combustion chamber connects blast pipe; Air inlet pipe puts in the burner hearth from the lower end of burner hearth, and the top of air inlet pipe is higher than the combustion gas through hole and is lower than the top of burner hearth.
The outside of above-mentioned body of heater has heat-insulation layer.
After adopting technique scheme, fuel gas at first bumps with hearth wall after entering burner hearth, making gas carry out the first time mixes, mix later gas and enter the combustion chamber, bump with chamber wall again, carry out the second time and mix by the combustion gas through hole, burn in the combustion chamber through the fuel gas that mixes for twice, with the hearth wall heating, the gas that makes burner hearth further improves burning of gas efficient through giving heat simultaneously.The utility model gives the method that heat and secondary mix by gas and increases substantially efficiency of combustion, again owing in the arranged outside of body of heater heat-insulation layer, the heat radiation of body of heater self is reduced, the thermal efficiency is higher.Simultaneously,, can avoid air inlet pipe and hearth wall to be burnt out, increase the service life owing to there is not the naked light burning in the burner hearth.
Description of drawings
Accompanying drawing is the structural representation of an embodiment of the utility model.
The specific embodiment
As shown in drawings, gas fired-boiler described in the utility model comprises body of heater 1, is arranged on the burner hearth 2 of body of heater 1 inside, and the outside of body of heater 1 has heat-insulation layer 7; The outside of burner hearth 2 has combustion chamber 4, and the lower end of combustion chamber 4 has combustion gas through hole 6 to be communicated with the lower end of burner hearth 2, and the upper end of combustion chamber 4 connects blast pipe 5; Air inlet pipe 3 puts in the burner hearth 2 from the lower end of burner hearth 2 and is communicated with burner hearth 2, and the top of air inlet pipe 3 is higher than combustion gas through hole 6 and is lower than the top of burner hearth 2.The shape of body of heater 1, burner hearth 2 can be designed to drum shape, square or oval tubbiness as required.
During use, fuel gas enters burner hearth 2 by air inlet pipe 3, at first bump with hearth wall, making gas carry out the first time mixes, mix later gas and enter combustion chamber 4 by combustion gas through hole 6 along the arrow direction, bump with chamber wall again, carrying out the second time mixes, burn in the combustion chamber through the fuel gas that mixes for twice, in with the heating of the water in the body of heater 1, hearth wall is heated, the gas that makes 2 li in burner hearth further improves burning of gas efficient through giving heat.Heat-insulation layer 7 can reduce the heat radiation of body of heater 1, reaches the purpose of insulation.
Claims (2)
1, gas fired-boiler, comprise body of heater (1), be arranged on the inner burner hearth (2) of body of heater (1), burner hearth (2) communicates with air inlet pipe (3), it is characterized in that: the outside of burner hearth (2) has combustion chamber (4), the lower end of combustion chamber (4) has combustion gas through hole (6) to be communicated with the lower end of burner hearth (2), and the upper end of combustion chamber (4) connects blast pipe (5); Air inlet pipe (3) puts in the burner hearth (2) from the lower end of burner hearth (2), and the top of air inlet pipe (3) is higher than combustion gas through hole (6) and is lower than the top of burner hearth (2).
2, gas fired-boiler according to claim 1 is characterized in that: the outside of body of heater (1) has heat-insulation layer (7).
