Steam TH Calculator

Steam TH help and math Final.docx

[koay9f]

Just hours/year for operating hours. Default = calculated value from settings

[koay9f]

Add dropdown near "Fuel Cost" Label = "Fuel Type" Options include: "Natural Gas" (Default), "Steam as Utility", "Other Fuel"

[koay9f]

UI Revamp. should take in to account the above comments. If fields are not organized like the other TH calcs (placement of OppHours and costs, etc) make more like the others Fuel type determines two things: Name & Units of Fuel/Steam Cost Type of utility in OppSheet (NG --> NG; "Other Fuel" --> Other Fuel; "Steam as Utility" --> Steam)

• Utility Type should be locked for the calculator, like Compressed Air. Choose once and then it is that for the other equipment and modification

• Pressure is not being converted to MPaa before being sent to suite

• Pressure default value should be 100 psig (which is 0.790801 MPaa, what the default value currently is...)

• Flow Rate units label should be lb/hr (imperial) and kg/hr (metric)

• Flow Meter Method -- Steam use result is not correct (also putting in Math issue, but the math in the suite looks okay so I'm not sure what the problem is) --- If use 1000 hrs/yr; NG; 10 $/MMBtu; 0.79 "psig" (actually 100psig or 0.79 MPaa); 100%; Flow Meter Method; 1000 "ft3/hr" (actually lb/hr); 1 unit --- result should be 1000 klb/yr (MEASUR is giving 1 klb/yr) and 881.1 MMBtu/yr (this is correct)

• Mass Flow of Air (Measured & Nameplate) -- label for Steam Flow Rate should be klb/yr and tonne/year (result looks correct) -- value in results section for "Steam Use" is reading zero (using default values), I think this is the same problem that Flow meter is having, it is dividing by 1,000 somewhere and the value is just really small

• Mass Flow of Water -- make the default water flow rate 2.5 gpm -- value in results section for "Steam Use" is reading 1(using default values), I think this is the same problem that Flow meter is having, it is dividing by 1,000 somewhere and the value is just really small

• Offsheet -- value in results section for "Steam Use" is reading 454 (using default values, should be 454,000), I think this is the same problem that Flow meter is having, it is dividing by 1,000 somewhere

Mass flow of Air Measured Steam Flow rate Also a problem in Modified. And "Nameplate" Looks okay in metric

Mass flow of Water - Something is screwy

Offsheet and Flow Meter look good. Other Issues look good also.
