A type of boiler that passes water-filled tubes through a heated firebox
Fire tube boiler
A type of boiler that passes hot gasses through tubes to heat and vaporize
What Is a stem-trap
a device used to separate condensate from steam and return it to the boiler to be converted to steam.
Thermostatic steam trap
a type of steam trap that is controlled by temperature changes.
float steam trap
a steam trap that operates with a float that opens a valve as the condensate level rises.
Define: Boiler load
Plant demand for steam.
Gas-filled sections in a boiler-fuel gas burner
What is a down comber?
The inlet tubes from the upper to lower drum of a water-tube boiler; these tubes contain hot water.
Steam generating drum
a large upper drum partially filled with feedwater.
This drum is the central component of a boiler, it is connected to the lower mud drum by the downcomer and riser tubes and receives steam from the steam-generating tubes
Define: Mud drum
The lower drum of a water-tube boiler.
A section of a fired boiler used to heat feedwater before it enters the steam drums.
Why do boilers have fans,
Fans provide airflow through the furnace creating a slight draft or negative pressure.
Steam pressure and temperature.
For every temperature of water, a corresponding pressure of steam exsist.
Super high pressure steam (super heating)
Removes the steam from the upper steam water drum and heats it up at essentially the same pressure.
What is the shortest discharge line from the lower (mud) drum?
1. Water tube. or down comer or riser.
Why is condensate recovered?
It can cause many serious problems.
Water flow in a water tube boiler, from where to where and how?
Bucket steam trap
During operation the steam enters the bottom of the trap via the inlet and filled the inverted bucket, An air vent is located on the top of the bucket gases escape throught this hole and into the outlet line.
