fire tube boiler with superheater

Boiler Operation Training - from Start-up to Lay-up

Overheating of superheater tube element result in sagging and failure of tubes and may even trigger a hydrogen fire in the boiler. To protect the superheater from overheating during start-ups, the superheater is drained of any accumulated condensate and a vent provided in its outlet header is left partially open until the boiler is put on load.

Types of Superheater Boiler | Technology-Articles.com

Jan 10, 2018· 1. Radiant Superheater. Radiant superheater is a superheater positioned in the boilers combustion chamber, so the superheater pipes instantly absorb the radiant heat from the combustion inside the furnace. In modern water-tube boilers, these superheater radiant pipes are placed hanging over the top of the boiler furnace.

Superheater Tube Corrosion on Municipal Solid Waste Fired

On the 29th of July, 1975, a superheater tube failure occurred on the No. 2 boiler. It was located in the fourth section from the left side and in the seventh tube from the front. A closer examination found that much of the tubing in the section was very thin, consequently the entire section was replaced.
