Do we need this much protection? There are some heat transfer and pumping viscocity penalties for using glycol.Glycol Supply Temp200 FMaximizing supply tempGlycol Return Temp160 FPuts us comfortably with in a 6" pipie size with plenty of room for growth.Glycol dT40 FA 60FdT would get us down to 240 GPM, but 3X the pumping energy and poor control at HX's.Maximum Heating Demand6400000 mmBTUFrom 6/8/12 Meeting w/ Dahlson. Typically the envelope heat loss in this climate is appox. 50 BTU/ft2/hr. This does not include DHW demand.Fluid Flowrate356.3 GPMFlow = Heat/dT*CpFluid Velocity3.8 FPSRough based on pipe size and flow rate.Fluid Pressure Drop0.9 Ft wgBased on pipe size and flow rate.Operating Pressure50.6 PSIGAssume 1 mile of distribution piping, additional 50% for fittings and valves, 10' for HX, 10' for balancing valve, 20' for boiler.Maximum Allowable Pressure150 PSIGBased on piping, valves, and HX'sMaximum Allowable Temp210 FDon't want Glycol to boil.Supply Size6 INCHESReturn Size6 INCHESPiping MaterialASTM A53 Grade B SteelStandard Carbon Steel, recommended preinsulated piping manufacturers; Permapipe, Rovanco, ThermacorInsulation Typeed Cell Polyisocyanurate or Polyeurethane Foam 2lb/ft3 densityEither prefabbed polyisocyanurate or field installed polyeurethaneInsulation Thickness3 INCHESHeatloss Approx. 20 BTU/ft/hr @ min 4' depth, 12 Btu/h.ft2.F/ft soil conductivity, 50F soil temp.Jacketing Material125mil HDPE ASTM D1248/D3350Thermal Expansion Controlpre-fabricated/insulated expansion elbows, Z-bends, loops, and anchors.Per Manufacturer's recommendations, avoid mechanical expansion joints if possible as they cannot be direct burried and are a maintenance issue.Notes:1. Installed minimum separation distance 2' CTC. 2. Trench bedding and pipe cover: A 4” layer of sand or fine gravel tamped in the bottom of the trench, evenlybackfilled with the same material in 6” compacted lifts to a minimum height of 6”above the top of the piping system. 3. Piping welded per ASME 31.1 Power piping code.4. Based on the above information we would use a 356.3 GPM pump at 50.6 PSIG of pressure loss. This would be equivelant to a B&G 80 3X3X7B with a 15 HP motor.P:\2012\12082AN Tok Biomass Study\Tok Biomass Calcs.xlsPage 1 of 1 Project: Tok BiomassProject #: 12082ANTitle: Yearly O&M Costs Per Customer ConnectionEngineer NEK/DTRInput Date: 8/4/2012Building Name Item QTY Units Cost Customer Cost Utility CostTypical BuildingExpansion Tank 1EA $20 $20 -Air Separator 1EA $20 $20 -Brazed Plate Heat Exchanger 1EA $82 - $82Circulation Pump 1EA $20 $20 -Pressure Guages 7EA $14 $14 $14Double Check Valve 1EA $20 $20 -Pressure Reducing Valve 1EA $20 $20 -Check Valve 1EA $10 $10 -Isolation Valve 9EA $10 $10 -Auto Air Vent & Isolation Valve 1EA $12 $12 -Drain Valve w/ Hose Connection 5EA $10 $10 -Balance Valve 1EA $12 $12 -2-Way Control Valve (w/ Actuator) 1EA $15 - $15Thermostat 1EA $10 - $10Thermometer 4EA $5 $5 -Piping Insulation 60LF $5 $5 -1-1/2" Black Steel Fittings 1BATCH $20 - $201-1/2" Black Steel Pipe 200LF $75 - $751-1/2" Copper Fittings 1BATCH $20 $20 -1-1/2" Copper Pipe 40LF $65 $65 -Total Cost/Yr$465 $263 $216Notes / Assumptions:Use "RSMeans Facilities Maintenance & Repair Cost Data" - 2012 edition Sections include: Maintenance and Repair / Preventive Maintenance / General Maintenance (cleaning)Dollar Values Given are for "Total Costs, Including Overhead&Profit"City Multiplier = Fairbanks, AK, Weighted Avg = 119.1 = will use 150 for Tok.All cost values will be $/yrAssume contract HVAC service at $100/hrP:\2012\12082AN\Tok Biomass OM costs.xlsxPage 1 of 1
