Description
Technical field
The utility model is related to heating equipment, especially a kind of soaking type large size crucible heater with heat recovery function.
Background technology
Natural gas was heated, but in large-scale heater for heater due to the characteristics of it is readily burned, quick heating, by
It is easy to diffusion in gaseous fuel and initial temperature is low, easily so that the temperature of nozzles adjacent domain reduces, how influences homogeneous heating degree
It solves, is a research direction.
Invention content
The utility model proposes a kind of soaking type large size crucible heaters with heat recovery function, can be using flammable gas
The temperature uniformity in heater is promoted when body is fuel.
The utility model uses following technical scheme.
A kind of soaking type large size crucible heater with heat recovery function, the bottom of the heater are equipped with crucible holder and fire
Mouth；Heater top is equipped with smokejack；Smoke exhaust pipe is equipped at heater outer wall；The smokejack connects with smoke exhaust pipe；The row
Heat exchanger is equipped at smoke pipe beginning；Economizer bank is connected on the heat exchanger；The outlet of economizer bank and nozzles phase
It connects；Extraneous air is preheated through economizer bank at heat exchanger, and the air after preheating enters nozzles and mixed with fuel.
The nozzles use gaseous fuel.
The gaseous fuel is natural gas.
The burning groove that spiral shape rises, when crucible is placed on crucible holder, the burning are equipped at the heater inner wall
Slot is adjacent with crucible outer wall.
The nozzles are communicated with the beginning of burning groove.
The heater outer wall from-inner-to-outer is equipped with insulating brick and heat-preservation cotton, and the vertical middle part of heater outer wall is inserted
There is tempilstick.
Thermal insulation material is covered at the smoke evacuation pipe outer wall.
In the utility model, since high-temperature flue gas is used for air preheat, and the air after preheating is helped for natural gas
Combustion so that the fuel at nozzles has higher initial temperature, so that the temperature at nozzles can be kept with heater other positions
Relative equilibrium is conducive to be evenly heated material in crucible.
In the utility model, the burning groove that spiral shape rises is equipped at the heater inner wall, when crucible is placed in crucible holder
When upper, the burning groove is adjacent with crucible outer wall；The design causes the restricted in flow of gaseous fuel, reduces the expansion of gaseous fuel
Speed is dissipated, natural gas can more fully be mixed with hot-air, improve fuel combustion supplies thermal uniformity.
In the utility model, the heater outer wall from-inner-to-outer is equipped with insulating brick and heat-preservation cotton, the smoke evacuation pipe outer wall
Place is covered with thermal insulation material；The design can promote the temperature of discharge flue gas so that flue gas acts on preheating of air more preferable.

Specific embodiment
As shown in Figs. 1-2, a kind of soaking type large size crucible heater with heat recovery function, the bottom of the heater is set
There are crucible holder and nozzles 5；Heater top is equipped with smokejack 1；Smoke exhaust pipe 8 is equipped at heater outer wall；The smokejack 1 and row
Smoke pipe 8 connects；Heat exchanger 6 is equipped at 8 beginning of smoke exhaust pipe；Economizer bank 9 is connected on the heat exchanger 6；Air
The outlet of economizer bank 9 connects with nozzles 5；Extraneous air is preheated through economizer bank 8 at heat exchanger, the air after preheating into
Enter nozzles 5 to mix with fuel.
The nozzles use gaseous fuel.
The gaseous fuel is natural gas.
The burning groove that spiral shape rises, when crucible 7 is placed on crucible holder, the burning are equipped at the heater inner wall
Slot is adjacent with 7 outer wall of crucible.
The nozzles 5 are communicated with the beginning of burning groove.
The heater outer wall from-inner-to-outer is equipped with insulating brick 3 and heat-preservation cotton 2, the vertical middle part of heater outer wall
It is inserted with tempilstick 4.
Thermal insulation material is covered at the smoke evacuation pipe outer wall.
Embodiment：
Heater is passed through nozzles before ignition, hot-air, and hot-air is made to mix to promote fuel gas with natural gas
Initial temperature, after heater is lighted a fire, the high-temperature flue gas in combustion chamber enters smoke exhaust pipe, and heat source, external cold sky are provided for heat exchanger
Gas first enters heat exchanger preheating through economizer bank, then is passed through nozzles and participates in burning, takes full advantage of fume afterheat to air
Preheating, without separately setting air preheat heat source again.
