THE SUPERHEATER COMPANY, LIMITED, of London and Manchester, is devoted exclusively to the design and manufa6ture of Superheaters for Marine, Locomotive and

Stationary plants, and to the development of the use of High-Pressure High-Temperature Steam. It co-ordinates through its associated companies the technical resources and practical experience of a world organisation of a highly specialised character.

The design and construction of Superheaters have always presented problems demanding specialised treatment and, now that Superheaters have to withstand conditions which are far more severe than those to which any other parts of steam-generating plants are subjected, it is more than ever necessary that they should be designed and manufactured by those who, having devoted special study to the problems involved, can embody their extensive experience.

Special machines are employed for manufacturing Marine, Locomotive and Stationary Boiler Elements with "M.L.S." integrally forged return bends.

There are three complete forging plants used for the production of these bends from different sizes of tubing. Each plant comprises two forging machines, a rotary hammer, a swaging machine and a flattening and cutting-off machine. An oil-flood furnace is alongside each machine.

The forging machines are also used for upsetting the metal at tube ends to provide extra thickness for machining to spherical shape. Most of the machines are of novel patented construction specially designed for the particular class of work performed.

Other work of note done by the plant is the manufacture of bifurcated tubes for furnace water- cooled walls, and the shop is equipped with modern tools for the machining of Marine, Locomotive and Stationary Superheater headers.

In the case of stationary superheaters, it is interesting to note that the large size of modern water-tube boilers necessitates elements of such bulk and weight that special jib cranes and tackle have to be employed for handling during the various forging operations. The shape and formation of Stationary elements vary greatly, and arc determined by the typo of boiler to which they arc fitted and the location of the superheater. A large amount of space is necessary for bending, handling, laying-out and setting to shape. The elements arc ball-ended and built up in a similar manner to marine and locomotive types. As an example, the high-pressure boilers for Synthetic Ammonia and Nitrates, Ltd., each evaporating 269,000 pounds of Steam per hour, at a pressure of too pounds per square inch, arc fitted with "M.L.S." Superheaters to give a final temperature of 840 degrees Fahrenheit each element contains zoo feet of tubing and weighs 6 cwts.

The Designing, Engineering and Service Staffs of The Superheater Company, Limited, and its Associated Companies in the United States of America, Australia, Canada, France and Germany are at the disposal of all requiring advice and information regarding superheating. In addition to the Agents which represent The Superheater Company, Limited, in many countries, Service Engineers arc maintained in Great Britain and various parts of the world. These Service Engineers are fully trained in the operation of 'Marine, Locomotive and Stationary Boilers and Superheaters, and are at the disposal of all clients using "M.L.S." apparatus, and those desiring advice regarding installation of plant.
