Clean combustion

The low pressure hot water boiler Vitomax 200-LW (type M62A) is the successor to the popular Vitomax 200-LW (type M241) up to 6.6 MW. The three-pass boiler offers environmentally responsible clean combustion over its entire output range.

Defined and constant temperatures where the flame is produced support the stable formation of the flame and reduce the NOx formation. The straight-through flame tube enables the trouble-free deployment of a rotary atomiser, e.g. for the combustion of animal fat or heavy fuel oil. The boiler is approved for a safety temperature of 120 °C.

Wide water galleries ensure excellent natural circulation and a reliable heat transfer. No minimum water flow rate is required. There are water deflectors for an even distribution of the return water.

Numerous design features simplify the installation, commissioning and service:

• Reduced shipping dimensions compared to its predecessor
• Boiler cover that can be walked on
• Opening of boiler doors without removal of the flue supply lines or the burner
• Modular boiler platform which can be extended
• Large clean-out aperture at the end of the flame tube with inspection hose opening
• No lining required; the front reversing chamber is of a “dry” design; the rear reversing chamber is fully water-cooled
• 100 mm thick composite insulation

Specification

• Low pressure hot water boiler, 2.3 to 6.0 MW, 6/10/16 bar
• Dimensions (height x width x depth): 2 720 x 2 400 x 5 850 mm (6 MW)
• Weight: 12.1 t (6 MW, 10 bar)
