Fire Tube Boiler - thehsfoundation.org

Fire-tube boiler - Wikipedia. The earliest form of fire-tube boiler was Richard Trevithick's "high-pressure" Cornish boiler. This is a long horizontal cylinder with a single large flue containing the fire. The fire itself was on an iron grating placed across this flue, with a shallow ashpan beneath to collect the non-combustible residue. Get a

Failure investigation of super heater tubes of coal

Failure of super heater tube of boiler is the major concern of forced outages at coal fired thermal power plant. Flue gas passes over super heater tubes leading to damage over the time of operation and termed as fireside damage/corrosion. Again the extent of damage is dependent on quality of coal, materials used, operation and maintenance.
