Boiler - Wikipedia

Fire-tube boiler: Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point.

Blast Furnace Gas Fired Boilers - Boiler Design & …

The boilers are sometimes required to fire blast furnace gas [BFG] (a low Calorific Value [CV] waste stream from the process), along with other fuels such as pulverised coal and coke oven gas. The combustion of these fuel sources can impose conflicting design objectives on the boiler designer which can be difficult to achieve.

7. CONCLUSION: The energy contained in the Blast furnace Gas (CO majority) having a calorific value 670 Kcal/Kg can be utilized by burning it in a dual fuel fired boiler to produce steam for Power generation as well as process heating purpose. Proper operation of the boiler increases the efficiency of the steam generation system. As the CO gas contain some fly ash after filtration, so it is very much necessary to maintain the boiler …
