An advertisement for James Howden & Co, marine and general engineers of Scotland Street in Tradeston. It appeared in the Commercial year book of the Glasgow Chamber of Commerce & Manufactures in 1915. The 25,000 HP Howden Zoelly impulse steam turbine illustrated was the largest of many supplied to local authorities in Britain.
James Howden & Co was established in 1862, initially to manufacture marine engines and boilers. The firm's success owed much to the inventiveness of founder James Howden (1832-1913), who registered a vast number of patents in many fields of engineering. The best known was the forced draught system, introduced in the 1880s, which used waste gases to heat the air in a boiler's combustion chamber and which was adopted by shipbuilders around the world.
Howden's range of activities was extended in the early 20th century to high-speed engines and turbines for land use, chiefly for the supply of electrical power. The firm supplied the boring machines used to excavate the Channel Tunnel, which opened in 1994. The Howden Group continues to manufacture a wide range of industrial machinery.
