Proven for decades and still pioneering
The double-flame smoke tube boiler with separate smoke gas passages is also suitable for operation with only single firing. The three-pass principle with a rear smoke gas reversing chamber lying in the water chamber was patented in 1952. The economizer and superheater can be upgraded in simple modular construction. The dimensions of the flame tubes, smoke tube bundles, water chamber and steam chamber have optimum thermodynamics. Radiant and convection heating surfaces generate a special dynamic in conjunction with the possibility of single-flame tube operation. The fed fuel heat is transferred evenly by means of flow components mounted on the water side, and it is then converted into steam without material stress.
