Product Review Cameron Abney and Associates Formulas and Conversion Charts

A.            Boiler Formulas

Boiler Horse Power (HP):

BHP = (Lb/hr) * FE / 34.5

where Lb/hr is pounds of steam per hour and FE is the factor of evaporation.

Steam:

S=HP * 34.5 * t

where HP is boiler horsepower and t is time (h).

Cycle of Concentration of Boiler Water:

CYC=Bch / FCh

where  Bch  is  ppm  water  chlorides  and FCh is ppm feedwater chlorides.

Differential Setting (lb):

Delta S = P1 - P2

where P1 is the cutout pressure and P2 is the cut in pressure

Factor of Evaporation:

FE = SH + LH / 970.3

where SH is the sensible heat and LH is the latent heat.

Force (lb):

F=P / A

where P is pressure (psi) and A is area (in^2).

Horsepower (HP):

HP=(d * t) / (t * 33000)

where d is distance, F is force, and t is time.

Inches of Mercury (in):

InHG=P / 0.491

where P is pressure

Percent of Blowdown:

%BD=(PP - RP) / PP

where PR is popping pressure and RP is reseat pressure

Rate of Combustion (Btu/hr) RC=H / (Vf * t)

where H is heat released (BTU), Vf is volume of furnace (ft^3), and t is time (hr).

Return Condensate Percentage in Feedwater RC%=(MC – FC) / (MC – CC)

where MC is the makeup conductivity (μohms), FC is the feedwater conductivity (μohms), and CC is the condensate conductivity (μohms).

Static Head Pressure (lb)

SHP= Bpr * 2.31

where Bpr = boiler pressure (psi)

Temperature Conversions:

F to C

C = (F – 32) / 1.8

C to F

F = (1.8 * C) + 32

Total Force (lb)

TF = P*A

where P is pressure (psi) and A is the area of valve disc exposed to steam (sq. in.)

Water Column (in)

WC = P / 0.03061   where P is pressure (psi).
