Furnace Exit Gas Temperature Control (FEGT) Monitoring.

Boilers operating with high furnace exit gas temperatures, which are often a direct function of water wall cleanliness, are particularly prone to coal ash corrosion from ash constituents. Limiting FEGT to a minimum approx 30-40 degree C below the ash softening temperature can substantially improve the convective pass fouling problem, because the dry ash leaving the furnace will not stick to the steam

Superheated Steam Water Tube Marine Boilers

Water and steam circulate through the vertical banks of tubes; the inner ones supplying the top drum and the outer ones dropping steam and water back to the water drum. The water tubes are heated by heavy fuel oil, which is swirled into furnace by the oil burners combusting with 25% excess air supplied by the forced draught fans via an air heater.

How to Destroy a Boiler -- Part 1

Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.
