Not a bland powerplant Prototype Schuyler Otis Bland

摘要

SCHUYLER OTIS BLAND IS CONSIDERED THE PROGENITOR IN the use of high-pressure and high-temperature steam in merchant dry cargo ships. Even astute researchers will find very few unique exceptions before the Bland. The machinery on her had mass-production capability with highest reliability; setting a new standard for compact efficiency. There was nothing bland about the machinery on the ship. Naval engineers determined that 12,500 hp would give 18.5 knots on transit, well above the preceding emergency ships. IN A DECADE, STEAM PRESSURE CONDITIONS DOUBLED THE STANDARD 440 psi/740~0 power plant used on major Maritime Commission World War Ⅱ cargo ships. One hundred years before the first C2 ship, the most powerful ship on the Atlantic, Great Western, went to sea with a mere five psi boiler pressure. She became the first ship to cross the Atlantic at 10 knots. A professional trumpet player can generate approximately 2 psi. In 1843, the warship Princeton achieved an impressive 14-knot trial with 11-psi boilers.
