Electric Boilers Flashcards
An immersion type of electric boiler:
Passes current through the water
Generates heat utilizing a bundle of heating elements
Does everything shown here
Depends on water level to regulate steam production
Generates heat utilizing a bundle of heating elements
In an electrode type of electric boiler:
Current decreases as pressure drops
Current increases as the generating zone level drops
More steam is generated when the generating zone level drops
Electrical current decreases as pressure goes up
Electrical current decreases as pressure goes up
Electrode type boilers: Self regulate steam pressure Require complex control systems Require microprocessor control Require electrodes to be totally immersed in water
Self regulate steam prest
Water level in the generating zone of an electrode type boiler:
Has no effect on pressure
Is maintained by means of a feedwater regulator
Is constant
Is governed by feedwater flow
Is governed by load fluctuations
Is governed by load fluctuations
