33,475 Btu's=
1 Boiler HP
What is the total force being exerted on an 8 " x 24 " area of boiler plate that has 30 psi
acting upon it?
, TF= Area x Psi
8x24x30= 5,760 lbs.
What is the psi of 24 inches Hg.?
24x.491= 11.78 psi
When do you need a high pressure license for a hot water system?
Over 160 psi, greater than 250°F
The formula for Frequency
F=N x RPM/120
If your plant is burning # 6 oil with a high sulfur content, what impact do sulfur oxides
have when combustion temperatures are low?
, Give this one a try later!
There will be an increase in corrosion
A boiler produces 400 psi steam at 500°F. Normal saturated steam conditions are
444.6°F. What is the degree of superheat?
500-444.6= 55.4 degrees
1 Btu=
778 ft. lbs
What is the formula for finding Boiler Horsepower?
BHP= Ws/34.5
