* - burning heavy fuel oil or other kind of fuel with high sulfur content, boiler’s efficiency will not exceed 90 %.
Advantages:
-
Boilers are completed with a wide and dedicated range of economizers (bare or finned tubes type) to ensure the highest boiler performance (94÷95% efficiency on Low Heating Value) even with different available fuels.
-
Quick reaction to the load fluctuations.
-
Fuels: Natural gas, Diesel oil, Refinery gas, Lean gas, Reach gas, Coke Oven Gas, Process gas, Heavy Fuel Oil with sulfur content up to 5 %
-
The combustion is fully automated (boiler control system SCADA);
-
Boilers are fitted with Venturi type, high efficiency, axial flow type burner, able to work with low air excess.
-
Low NOx burners are usually mounted (in accordance with EU Norms)
-
Ultra-low NOx burners can be installed upon request (25 ppm NOx at 3% O2) with double or triple air register.
-
Fuel oil automation is obtained by means of compressed air, low pressure steam (wide modulation range) or by mechanical automation.
-
The boilers come in a package mode they are built entirely in factory’s plants and are fully tested before delivery. They are equipped with thermal insulation as well as combustion and automation systems, which saves the customer the complex and often expensive practice of assembling the unit on the spot and also make shorter installation period.
