Design

Its suitability for the unrestricted parallel or single bending stresses are avoided. The integrated rear flue
operation of its firing units is not only due to the stable gas chamber thus offers the advantages of the fully
separation on the flue gas side. The special design wetback cooling while significantly reducing its
measures for neutralising the tension forces in single- mechanical stress.
flame tube operation are crucial for permanent stabil-
ity. The flame tubes are pushed through in the front The unrestricted single operation provides high load
and rear floors and welded tightly all around. In con- flexibility. The modulation range is doubled, unneces-
trast to boiler designs with stud bolts, inadmissible sary energy losses can be reduced.
