Specification for liquid-fuels and
gaseous-fuels burners of boilers
1 Scope
This standard specifies the technical requirements for the classification and
model preparation, composition and basic configuration, basic requirements,
performance requirements, design and manufacture, inspection, testing and
detection, technical documentation and identification, packaging, transportation
and storage, installation, commissioning, use of liquid-fuels and gaseous-fuels
burners of boilers.
This standard applies to forced draught burners and natural ventilation burners
which use the liquid-fuels and gaseous-fuels for boilers. Power plant boiler’s
startup burners, various industrial furnaces, industrial heating furnaces, burners
for other purposes may make reference to this standard.

Gaseous-fuel
A gaseous combustible substance that generates heat when burned.
Note. The gaseous-fuels referred to in this standard include natural gas,
liquefied petroleum gas, coke-oven gas, mixed city gas, bio-gas, low-
calorific-value gas, combustible industrial tail-gas, hydrogen gas, methane.
3.6
Biomass pyrolysis gas
A low-calorific-value combustible gas produced by a pyrolysis process of a
biomass solid fuel.
3.7
Dual fuel burner
A burner capable of burning liquid and/or gaseous-fuel simultaneously or
separately.
3.8
Surface burner
A fully-premixed burner in which fuel is burned on the surface of a porous
medium.
3.9
Heat output
The amount of heat as released by the burner per unit time.
Note. The heat output referred to in this standard is based on the net calorific
value of the fuel, in the unit of kilowatt (kW).
3.10
Nominal heat output
The heat as released by the burner during continuous combustion per unit
time under rated conditions.
Note. The nominal heat output is expressed in QF, in kilowatts (kW).
3.11
Maximum heat output
Flame detector device
A device for monitoring the presence of a flame.
3.19
Main flame
A flame that burns on the main combustion nozzle.
3.20
Ignition flame
The flame that is first ignited to ignite the main flame.
3.21
Controlled shutdown
When the burner does not need to supply heat, the process of shut-down by
automatically cutting off the fuel supply.
3.22
Safety shutdown
After the safety device responds or the automatic control system fails, the
process of shut-down by automatically cutting off the fuel supply.
3.23
Pre-ignition time
The time interval between the startup of discharge of the ignition electrode
and the opening of the fuel valve.
Note. The pre-ignition time is expressed in ty, in seconds (s).
3.24
Ignition safety time
The safe time for the burner’s ignition flame to ignite, that is, when the
ignition flame is not formed, the interval between the time when the ignition
fuel control valve gets the opening signal and the time when it gets the
closing signal.
