Energy saving natural gas burner for Rotary kiln drying
Application:
Burning System for Rotary kiln on industry fields like Power,
Chemical, Metallurgy, Building material etc.
Refer to different kiln type, different fuel gas characters and
different technical condition, the burner will design and produce
accordingly.
Gas Burner is research and developing for rotary kiln that burning
with single or various gas fuel, which not only ensure all the
advantages and specificity of four-channel burner, but also enhance
the application of burning. The burner have special structure and
reasonable technical parameters, guarantee the gas fuel fully
mixing with air, primary air and secondary air, which to ensure
stronger heating intensity, higher burning efficiency, easier
adjustment. Burner can be applicable for various metallurgy and
chemical rotary kiln.
Gas Burner is mainly composed with Pipe, Nozzle, Ignition device,
Metal corrugated compensator, Butterfly valve, Pressure measurement
and Protection layer etc. The mainly features are:
1. Pipeline
From outside to inside respectively, the pipeline has consist of
Axial wind channel, Swirling wind channel, Gas wind channel,
central wind channel and ignition channel. And the ignition is just
for igniting, so called four-channel burner.
2. Nozzle
Nozzle made by special material, spray mouth sectional area of
axial wind channel, swirling wind channel and gas wind channel are
adjustable, so that can adjust the spray speed of each channel. The
nozzle is the key part to ensure flame shape.
3.Ignition Device
Located in the central wind channel, used for automatic igniting.
4.Metal Corrugated Compensator
Which is the key part to connect each channel, sealing and adjust
flame shape, and allowed process axial movement with connected
channel.
5.Butterfly Valve
Used for adjust air volume. Among in 5 valves, 3 used for adjusting
flow rate of central wind, swirling wind and axial wind; another 2
manual valves used for adjusting flow rate of ignite gas and main
gas.
6.Pressure Measurement
Used for indirectly indicate spray speed of burner wind mouth.
7.Protection Layer
Fireproof casting layer, which casting by the owner.
