ganization, thus not only 
relieving the customer of 
the necessity of himself 
harmonizing any differences 
between two separate con- 
tractors, but also saving 
in initial cost because of 
dealing with one concern 
for one unit rather than 
with two concerns. The 
Ladd engineers and the 
Combustion Engineering 
Corporation engineers have 
in the short time since the 
consolidation of the two 
companies demonstrated 
the logic and advantage of 
boiler experts and com- 
bustion experts coming to- 
gether. 
One of the outstanding results of this combination is a 
new unit with a number of interesting new features installed 
at the Fordson Plant of the Ford Motor Company at River 
Rouge. This is the largest steam boiler in the world, develop- 
ing approximately 17,000 HP. and operating at extremely 
high efficiency. Not the least interesting feature of this 
installation is the fact that there is no brickwork in the fur- 
nace, the furnace walls being made of boiler tubes with 
fins or steel flanges welded to them. Thus the side walls 
of the furnace become boiler heating surface instead of a 
ronstant source of expense because of burned-out brickwork. 
In the Kips Bay Station of the New York Steam Corpora- 
tion, there are in operation three large Ladd Water Tube 
Boiler Units—each designed for a steam production of 
825,000 lbs. per hour. These boilers are also equipped with 
Combustion Engineering Corporation water walls, water 
screens and air heaters. The coming together of the Ladd 
Company and Combustion Engineering Corporation marks 
a new step in power plant design, for it is the first time in the 
history of the country that a prominent boiler concern has
