or assembly process not recommended or authorized.
3. Safety Guide
Only those who were trained and qualified person can follow the manual to operate or
adjust the combustion system. The fire was prohibited within a radius of 5 meters of the
combustion system. Flame, non–covered light sources or heat sources shall not be brought
to the combustion area unless it is related to the process. Welding in combustion control
area shall be approved to ensure the safety in the area and also preventive measures
should be taken into consideration.
Before starting, the operator must confirm whether the burner and gas pipeline are in
normal working condition, and there is no flammable substance around the burner. The
burner must be operated with fuel and oxygen or air. The ignition and operation of the
burner must be performed at the specified position. The burner has been correctly and
safely installed before ignition. The ignition of the burner needs to be performed after the
combustion chamber is purged. If it is ignited at a low temperature, it needs to be replaced
with 5 times the volume of the combustion chamber to avoid explosion.
However, it is not necessary to purge when the temperature is higher than 750°C. Air pipe
or gas pipe connected with burner should be tight enough with no leakage, also the
periodically check air or fuel nozzles of the burners to prevent to be blocked by dust, slag
or other materials.

ATTENTION：DANGER OF BEEN BURNT
When burner in operation, combustion is severe, so the burner must be fixed. Hoses or
cables in area of the combustion system must be suitable for high temperature, to prevent
high temperature failure or cause safety accidents. Burners should be periodically
inspected and cleaned. Copper wire brush may be used, if necessary, to clean burner head.
The burner system should be checked twice a year for safety operation.
Burner commissioning shall take care of ignition position, minimum and maximum output
position. Following interlocks will cause emergency stop, including gas low pressure, high
pressure or low combustion air pressure, as well as emergency stop is trigged, the main
power is out, UV signal failure or kiln safety conditions (such as high temperature limit, flue
system opening, etc.) will cause the burner lockout. Users need to know the maintenance
interval recommended by the manufacturer and the interval specified by national laws,
whichever is shorter.
4. Description
SRB series burner is suitable for air and natural gas combustion heating in radiant tube.
The burner is composed of rear cover and burner body. The rear cover is equipped with
accessories such as a gas orifice, a pressure measuring taps, a peep sight.
Spark plug is fixed on rear cover and flame rod or UV scanner to be used for flame
monitoring.
The burner body has combustion air inlet and exhaust gas connection. The material for
burner body is die-casting aluminum alloy and adopts a double-layer structure to reduce
the temperature. Burner nozzle and recuperator are installed on the burner body, and the
burner is connected to the furnace wall or the radiant tube through the installation flange
on the burner body. The air inlet is equipped with an air hole plate, and the flue gas channel
is equipped with a thermal insulation fiber.
Recuperator is used to recover the waste heat of the flue gas and preheat the combustion
air. According to different working conditions, there are two materials available: metal and
silicon carbide. A large number of fins are arranged on the inner and outer surfaces of the
recuperator, and protrusions are arranged on the inner and outer surfaces of the ceramic
recuperator to enhance the heat exchange efficiency. Burner structure refer to Fig 1.

Flame inner tube
The flame inner tube is made of silicon carbide, which can withstand higher temperatures;
the standard segment spherical coupling method is used for splicing, which has a certain
degree of flexibility and allows slight bending and deformation of the radiant tube. Refer
to Fig 2.

Attention!
–When the power outage is more than 10 minutes,
remove the burner from furnace, to prevent the burner
from being damaged.
–The exhaust tube is extremely hot, please do not
touch by hand.
–Do not remove the metal gas hose or locking device
when the gas is not completely shut down

1. Preparation before burner installation
Before install burner into radiant tube, make sure all burner parts are in good condition, no
cracks on SiC recuperator and inner tube.
Check burner mounting bracket is solid and strong to support burner and radiant tube
Before the pipe is connected to the burner, it must be purged in advance to prevent welding
slag or other debris from entering the burner and affecting the normal operation of the
burner. If you need to perform pipeline welding after installation, make sure that no welding
slag or molten material falls into the pipeline or burner during the welding process.
2. Burner installation
Burner orientation can be adjustable.
Once the exhaust gas outlet direction is decided, then the combustion air inlet can be installed
at any horizontal or vertical position, refer to Fig 4.

In order to ensure the accuracy of the orifice plate measurement, the burner air and gas
inlet positions must ensure that there is a straight pipe section of 5 times the pipe
diameter and no other resistance components;
The burner is equipped with a spark plug with cooling air, and the cooling air interface
is a Ø8 connection. It is recommended to use a metal tubing to take the combustion air
from the upstream of the air shut-off valve.
3. Burner operation requirement
The excess air coefficient of this series of burners must be ensured to be above 1.05,
and cannot be running at gas rich mode;
According to the actual situation on site, regularly maintain the burner, check and clean
the burner, recuperator and spark plug;
Regularly check the burning status of the burner, and track the flue gas data of the
burner to avoid damage to the burner due to abnormal combustion
The burner can run at pulse control, with turn down ratio 2:1; while running at
modulation control, the turn down ratio is 3:1.
