GENERAL INFORMATIONS
The "JHMG" gas burner series is a blown-air burner which can operate with natural gas, LPG, lean gas and gas with
low calorific power (on request). It was designed for the installation in all the process in which it is necessary to obtain
a deeply oxidizing combustion to limit working temperature.
The completely automatic working allows on-off regulations, high/low flame, air/gas modulating.
The last allows to obtain max.-min. regulation ratio until 15:1.
The maximum thermal potentiality is 1,569kW (1,350,000kcal/h) while the minimum potentiality can come up to
5.8kW (5,000kcal/h).
Combustion air temperature required for this burner can change from room temperature until 300 °C.
A particular care has been dedicated to CO and NOx emissions produced by combustion process, these elements are
lower than limits required by EN 676 regulations.
Burner structure is painting casting, the body is of iron, the bottom of aluminum, the parts in contact with flame of
refractory steel and Nickel Chrome alloys.
The burner has ignition and flame revelation electrodes, pressure switch to measure air and gas instantaneous flows,
flame indicating light.
FEATURES
+ Direct spark ignition, ionization flame detection electrode or U.V cell.
+ For natural gas or LPG, other gaseous fuel on request.
+ Max.-min. ratio 15:1
+ Available as complete version with gas ramp, according to EN 676 on right or left hand.
+ Easy to install, to start, to operate.
APPLICATIONS
+ All types of kilns, suitable for oxidative, stoichiometric or reducing combustion.
+ Ceramic, Bricks, Refractory:
- Roller kilns, Tunnel kilns, Intermittent kilns, Melting kilns.
- Continuous and Intermittent Dryers.
+ Iron metallurgic Industry.
+ Surfaces Treatment.
+ Glass : Hardening ovens.
+ Printing and Packing : Air Heaters for Rotogravures, Flexographic and Coupling and adhesivecoating Machines.
+ Food : Cereal Dryers, Roasters.
+ Drying Tobacco etc.
+ And furthemore, for any application which requires a wide regulation automatic gas burner,capable of operating
in a strong vacuum or with strong counter-pressure.
