Abstract

The economiser has a horizontal cylindrical shell (6) which is divided into upper and lower parts by partitions (7, 8, 9) with openings through which water can circulate between the upper and lower parts. Cold water enters (1) the upper part and heated water leaves (2) the lower part. Flue gases flow through a central smoke tube (3) through the lower part into a header space (5) from which smaller tubes (4) surrounding the central tube form a second pass to the smoke outlet (15). An auxiliary water chamber (10) is attached to the outside of the smoke header (5). It is connected by pipes (11, 12) with the upper water space and natural convection flow is set up through these. A single hairpin coil (18) runs from it through the central smoke tube (3).
