Abstract

The economy part (14) of the composite arrangement is formed by horizontal distribution and collection boxes (19, 20) with transversal horizontal tubes (21, 22). Between each pair of upper and lower tubes, are welded several tubes (23) with external surface enlarging components. The top side of the economy part is located immediately below the water level (16) in the steam boiler (10), and by virtue of short connecting pipes (25, 26) between the two main parts of the composite boiler, and a multiplicity of vertical tubes it is possible to achieve automatic circulation in the system. USE/ADVANTAGE - To produce steam, using a composite arrangement including a flue gas-heated economy part. (Dwq.No.1) (Previously notified week 9029, reissued week 9049)
