Jun 02, 2020 · Two main types of steam boilers are fire-tube and water-tube boilers. In general, water is heated to its boiling point via the combustion of fuel blown through multiple tubes submerged in water. The heat produced during this process is then injected into the system as steam. Steam will then flow through pipes to the equipment being heated.Learn More
6. After the boil-out period, allow a small amount of water to enter the boiler to create a slight overflow condition. Continue to boil and overflow until the water clears. 7. Shut the burner down. 8. Allow the boiler to cool to 120 degrees F. Drain the boiler using caution to insure that the water is discharged safely and in accordance with Learn More
