Fire-Side Corrosion: A Case Study of Failed Tubes of

The failures of superheater and reheater boiler tubes operating in a power plant utilizing natural gas or mazut as a fuel have been analysed and the fire-side corrosion has been suggested as the main reason for the failure in boiler tubes. The tubes have been provided by a fossil fuel power plant in Iran and optical and electron microscopy investigations have been performed on the tubes as

Fire Tube Boiler - Boiler and Mechanical Pow

What is a Fire tube boiler? The universal type of steam boilers is the smoke tube or fire tube boiler where the heat and gases of combustion (from furnace) pass through tubes that are enclosed by water. While in water tube boilers, water passes through tubes.Mostly used boiler in small and medium industries with different fuels and steam pressure requirements.

Steam Boiler Inspections Using Remote Field Testi

Fire Side Corrosion: Most fuel components can cause corrosion on boiler tubes. Due to incomplete combustion, deposits of combustion residue can change the heat transfer characteristics with

Boiler Fuels - AutomationWi

Boiler Fuels [] Introduction []. All boiler systems employ a fuel mechanism which basically comprises of the apparatus needed to supply fuel for heat generation. The design of the apparatus in use varies according to the kind of fuel employed in the system. Variety of fuels is available for application in boilers, each having different chemical properties.

Thermidaire Industrial Water Treatment Chemicals Boil

The purpose of an internal treatment programme is fourfold: (1) react with any feed-water hardness and prevent it from precipitating on the boiler metal as scale, (2) condition any suspended matter such as hardness sludge or iron oxide in the boiler and make it non-adherent to the boiler metal, (3) provide anti-foam protection to permit a

How to Destroy a Boiler -- Part

Fuel Explosions. One of the most dangerous situations in the operation of a boiler is that of a fuel explosion in the furnace. The photo above shows the complete devastation of a utility boiler. Conditions have to be just right for an explosion to occur and when a boiler is properly operated, it is not possible for such an event to take place.

Sulfur Recovery Unit Apply For Petrol-chemical And Natur

Waste Heat Boiler. As a necessary part of sulfur recovery unit, the waste heat boiler is a typical fire tube boiler. The multi-pipe mouth of the waste heat boiler is connected with the outlet of the heat reaction furnace, which is both the rear wall of the reactor and the end of the transition zone.
