Abstract
The utility model discloses a kind of novel boiler coal gas burner blow devices, including blast furnace gas burner nozzle, burner swirl vane is arranged in the end of coal gas burner, set is filled with a circular ring shape scavenging conduit on coal gas burner tube body of the burner swirl vane rear apart from 30 centimeters of coal gas burner end, uniformly 8 purge holes are arranged in interval on towards the scavenging conduit side surface circumference wall of swirl vane, the diameter of purge hole is 10mm, the back side of scavenging conduit is connected to the low-pressure steam pipeline that a diameter is 32mm, and the internal diameter of circular ring shape scavenging conduit is 200mm.The utility model can reduce the boiler burner blocking frequency, improves the economy of boiler, reduces boiler shutdown maintenance frequency.
Description
Technical field
The utility model relates to a kind of novel boiler coal gas burner blow devices.
Background technique
Xinjiang Bayi Iron & Steel Co., Ltd. of Baosteel Group Corporation's 240t/h gas fired-boiler mainly uses newly-built OY producer gas, in coal gas
Dust content is high, and for boiler burner after using 2-3 months, blocked area is more than 50%, and boiler load is limited, be only capable of maintenance 100 ~
130t/h, it is necessary to which blowing out is cleared up.Problem analysis: powder cabin content is high in OY producer gas, is easily collected on blast furnace gas burner nozzle
Place.It, can not Hand scarf burner during boiler operatiopn.
Summary of the invention
The purpose of this utility model is to provide a kind of novel boiler coal gas burner blow devices, can reduce burning in boiler
Mouth blocks the frequency, improves the economy of boiler, reduces boiler shutdown maintenance frequency.
The purpose of this utility model is achieved in that a kind of novel boiler coal gas burner blow device, including blast furnace
Burner swirl vane is arranged in coal gas burner, the end of coal gas burner, at burner swirl vane rear apart from coal gas burner end
Set is filled with a circular ring shape scavenging conduit on the coal gas burner tube body of 30 centimeters, towards the scavenging conduit side surface circumference wall of swirl vane
8 purge holes are arranged in upper uniformly distributed interval, and the diameter of purge hole is 10mm, and the back side of scavenging conduit is connected to a diameter and is
The low-pressure steam pipeline of 32mm, the internal diameter of circular ring shape scavenging conduit are 200mm.
In the case that in coal gas source, problem cannot solve in time, the starting point for reducing the blocking frequency of boiler burner is main
It is the frequency for reducing blast furnace gas burner nozzle blocking.Boiler service life is improved, the power output of boiler is improved.Therefore we introduce together
The low-pressure steam pipeline of 0.6MPa, φ 32, the pipeline section after blast furnace gas angle valve between burner installs blow device, due to burning
Mouth is that high, burnt gas shares, and has the coke oven gas pipe of a φ 80, in blast furnace gas pipeline in order to guarantee that annular burner is comprehensive
Purging, is arranged as annular for sweeping head.Burner steam blowing equipment is installed, the steam of high temperature can melt and remove on burner
Dust stratification, thus boiler load caused by effective solution burner dust stratification declines, and improves the economy of boiler, reduces simultaneously
The maintenance frequency of boiler.After this device, the time between overhauls(TBO) of boiler can be improved from pervious 3 months to 1 year.It is very big
Degree reduces the cost of overhaul；The stable operation that more importantly ensure that boiler, the production served as theme provide safe guarantor
Barrier.
Detailed description of the invention
The utility model is described in further detail below in conjunction with attached drawing.
Fig. 1 is the schematic perspective view of the utility model.
Specific embodiment
A kind of novel boiler coal gas burner blow device, as shown in Figure 1, including blast furnace gas burner nozzle 4, coal gas burner 4
End burner swirl vane 3 is set, in coal gas of 3 rear of burner swirl vane apart from 4 end of coal gas burner, 30 centimeters
On burner tube body set be filled with a circular ring shape scavenging conduit 2, towards the scavenging conduit side surface circumference wall of swirl vane on uniformly interval set
8 purge holes 5 are set, the diameter of purge hole 5 is 10mm, and the back side of scavenging conduit 2 is connected to the low pressure that a diameter is 32mm
Jet chimney 1, the internal diameter of circular ring shape scavenging conduit 2 are 200mm.
