I Need A Space Heating System Let’s Look At A Central Steam Plant Option

There Are A Lot Of Components Let’s Break The System Down

Boiler Steam Accumulator The Boiler Is An ASME Pressure Vessel:Requires Annual Inspection Special Risk Insurance Regular Maintenance

Boiler Steam Accumulator Stack 20% Fuel Loss

Boiler Steam Accumulator Stack 20% Fuel Loss Blow down To Maintain Steady Water Level & The Surface Clean From Froth & Debris Note: Blow down Tank May Need To Be An ASME Pressure Vessel 1% To 3% Steam Loss

Blower Motor Burner Electrical Cost Fuel In Fuel Cost

Cold Water In Water Softener To Control The Ph Resin & Salt Costs

Chemical Storage Chemical Feed Pump Chemical Costs To Control Water Quality

Water Softener Chemical Storage Chemical Feed Pump Deaerator Vented To Atmosphere To Remove Oxygen From Water Note: The Deaerator Is An ASME Pressure Vessel

Deaerator Vented To Atmosphere 3% to 8% Steam Loss Boiler Feed Pump Electrical Cost

Main Steam Header Transmission Losses Torn/Wet Insulation 3% to 10% Radiated Heat Loss

Main Steam Header Engineers often over-size coils based on the fins per inch and subsequent “fouling” factor The size of the coil may then be as much as 150% the size of one without “fouling” factor consideration! Each coil requires a steam trap to assure liquid does not enter the steam line Both the steam traps and coils require maintenance, at least annually.

The hot liquid from the leaving side of the coils (steam returning to liquid) accumulates in the condensate return tank

Condensate Return Pump Electrical Running Costs

Let’s Look At Some Costs 100 HP Steam Boiler Heating System Capital Costs Boiler:$34,000 D/A:$8,500 Softener$4,200 Chem. Feed$3,300 Chimney$3,000 Blow Down System$3,950 Cond. Return Tank$2,800 Return Pump$1,500 Traps$1,600 Heating Coils (4)$12, $75,750 Installation$50,269 Total$126,019

At 70% Load 289 GPH. 832,320 Gallons Per 2,880 Run Hours. Base Cost $9.00 Per 1,000 Gallons. ** The Steam System Has A 2 HP Boiler Feed Pump, 1 HP Burner Motor And 1.5 HP Condensate Return Pump. At KW Per HP. We Have Connected 4.5 HP Or KW 100% Efficient). Most Motors Are 75% Efficient So We Now use 4.476KW. Add 2 KW More For Controls And Valves And We Have A Connected Load Of 6.5 KWH, Prox. Electrical Cost Is $0.12 Per KWH. *** Based On Natural 1,000 BTU Per Cubic Foot. Max. Input For A 100 HP Boiler Is 3,347,500 BTUH. At A 70% Load Max. Input Is 2,343,259 BTUH. 1 Therm Is 100,000 BTU And Costs $1.35. The Figure Above Is Based On Therms Per Hour. 100 HP Steam Boiler Heating System Owning Costs (Annual)

Steam Heat System Capital Equipment:$75,750 Installation:$50, Total:$126,019 Annual Owning Costs:$118,173 First Year Investment:$244,192 Heatco Solution Capital Equipment:$46,900 Installation:$23, Total:$69,900 Annual Owning Costs:$49,868 First Year Investment:$119,768 First Year Savings: 51% Subsequent Years Savings: 58% Notes Regarding The Heatco Solution Each “fired” coil has its’ own independent control system. A component failure effects only that unit. A burner failure in the steam system results in no available heat. Each Heatco unit can modulate to maintain a set temperature, even with variable load conditions, resulting in additional fuel savings. No “fouling” of the Heatco coil as it does not have fins. Efficiency is maintained throughout the life of the system. Heatco has a 10-year warranty on the exchanger. Most steam coils have a one year warranty as does the boiler and burner. Heatco coils have much lower air side pressure drops than finned coils, often reducing the size of the connected fan/drive and subsequently reducing electrical costs.
