CORRUGATED PIPE FURNANCE
FIRE TUBE BOILERS ARE DESIGNED WITH A USEFUL LIFE OF MORE THAN 20 YEARS.
This long useful life is expected when the boiler is operated in accordance with the information provided in the operating manual and only if its pressure vessel design includes a hot corrugated furnace.
All Powermaster boilers with design pressures of 149 PSI or more, from 80 to 1500 HP, are manufactured with hot corrugated furnaces.
The most difficult part of fire tube boiler manufacturing process is undoubtedly the construction of the corrugated furnace; this process is also the most expensive, having the greatest impact on the final price of the boiler but also ensuring the boiler’s long useful life. A boiler with a hot corrugated furnace will be about 30-35% more expensive than a boiler with a smooth furnace.
While more expensive, the useful life of a boiler with a hot corrugated furnace is much longer than its smooth furnace boiler counterpart
ADDITIONAL ADVANTAGES OF A CORRUGATED FURNACE
The larger the boiler, the larger the furnace diameter necessary to house an efficient flame. Increasing the furnace diameter increases the required thickness of the furnace to withstand the desired pressures. If the boiler does not have any way to absorb the expansions and contractions of the material when the boiler is cycled, the tubesheets will be subjected to very large stresses that shorten the useful life of the boiler.
A corrugated furnace absorbs the expansions and contractions of the steel, avoiding ruptures in the tubesheets of the boiler caused by excessive stresses.
