Description

The boiler type ZFR is a shell boiler in three-pass technology with two completely separate flame tubes and smoke gas passages. A reliable steam and heat supply in the high output range.

This double-flame/smoke tube boiler with separate gas passages is suitable for operation with just one burner. The three-pass principle with a rear flue gas reversing chamber positioned in the water chamber was patented in 1952. The economizer and superheater can be easily added according to the modular principle. The dimensions of the flame tubes, smoke tube bundles, water chamber and steam chamber have been optimised from the point of view of thermodynamics. Radiant and convection heating surfaces create a unique dynamism when used in single flame tube operation. The heat supplied by the fuel is converted into steam without causing any material stress thanks to flow fittings mounted on the water side.
