Optimized Tube Nest Layout For Compact Single Pass Steam Condenser

Abstract: The invention relates to a method of forming an optimized tube nest layout for compact single pass condenser to achieve uniform steam flow distribution and equalized pressure drop across different tube bundles from all directions around the tube nest; the steam condensor condenser comprising a steam inlet (9) through which steam is received; a gas extraction pipe (11); a condensate outlet (8) through which condensate condensed on the cooling tubes is discharged, and a vessel (10), the method comprising the steps of ;constructing the tube nest with at least four six types of tube bundles (12,12a,12b, 13, 13a, 7) with a plurality of cooling tubes forming a first type of tube bundles (12,12a,12b,13, 13a)to act as condensing zone and a second type of tube bundle (7) acting as an air cooling zone; and arranging two tube nests as mirror image to each other in a double section condenser, characterized in that the steam received from a steam inlet (9) is allowed to pass into the first type of tube bundles through a central lane (5), and a plurality of formed steam lanes (3,3a,3b) having two side gaps (14), a top gap (15), and a bottom gap (16), and in that the air cooling zone (7) comprising at least of 5-10% total number of said plurality of cooling tubes surrounded by at least two baffle plates (6,6a) to prevent direct entry of the steam into the air cooling zone (7). {FIGURE 1}
