Recvery Ratings - Selecting A Prperly Sized Steam Heating Cil Nte: If the heating cil is a wrapped, baffled, and frce-circulated type please cnsult factry fr sizing. Determining The Ttal Square eet f Heating Surface Step 1 Determine The llwing Variables: Steam Supply Pressure: Recvery Rating: Incming Cld Water: Desired Ht Water: Steam Cnsumptin: Lbs./Hr. Step 2 Determine if the strage tank is t include a builtin Intra-Tank circulatr, r if it is t rely n natural cnvectin fr circulatin within the tank. Nte: If the Recvery Rating is greater than three times the strage capacity f the vessel, then the heating cil may be wrapped and baffled t allw fr an integral pump t frce circulate water ver the heating cil. The pump must be sized fr the maximum GPM recvery rating. Step 3 Use Chart #1 t determine the cnversin factr f heated per square ft f heating cil at the given steam supply pressure, temperature rise, and methd f tank circulatin. Selecting The Steam Cil Step 5 Determine the length f the heating cil. Nte: A cil in a vertical tank shuld be as clse as pssible t but nt exceed the diameter f the vessel. A cil in a hrizntal tank is typically apprximately 2 3 the length f the vessel " Apprximate Cil Length desired Step 6 rm Chart #2 (see fllwing page) starting with the smallest diameter cil, cntinue dwn the Cil Ttal Sq. t. clumn until the desired Sq. t. as determined in Step 4 is within the range. Then multiply the desired Sq. t. f heating surface by the length multiplier. This will yield the ttal length f the cil. If the resulting length is lnger than the required length as determined in Step 5, then cntinue t the next cil range until a suitable length can be selected. Step 7 rmulate the cil mdel number by using the mdel number cnfiguratr n page 8. Step 4 Slve fr the required square ftage f heating surface by dividing the ttal recvery by the cnversin factr slved fr in Chart #1 n the fllwing page. Cnversin actr = Ttal Square t. f Heating Surface Example: A 1000 galln 48" diameter vertical strage tank requires a cil rated t heat 1200 40-140 when supplied with 35 steam A. Because 1200 recvery is less than 3x the 1000 galln strage capacity, n intra-tank circulatr is required. B. rm Chart #1, we see that 35 g steam supply equates t 20 g steam in the tubes. Mving dwn t the 40-140 rw fr uncirculated tanks, we see that the cnversin factr is 35.0. This tells us that 35 will be heated frm 40-140 fr each square ft f cil heating surface. C. Slve r The Ttal Sq. t. Heating Surface 1200 35 = 34.2 Ttal Sq. t. D. Using Chart #2 the Mdel cil is selected because its length is suitable fr a 48" diameter vertical tank. Mdel Sq.t.
