was one of the frrsl of these high tem perature installations, having a rated capacity of 50,000 kw and a capability of 67,000 kw. The throttle steam con ditiona were 1450 pel and 1000 F with reheating to 1000 F. System growth re quired an increase in the unit sits and It was found that the reheat unit could be installed in approximately the game building volume aa the first unit. A comparison of size end performance of the first two units is shown In the
paper. The overall operating efficiency of the
plant ia shown in Fig. 2. Tho plant performance reaches a net plant heat rata for No. 2 Unit of 9750 Btu per net kwh at 56,000 kw. For the year 1951 the average heat rata was 9935 and for 1952 it was 9990 Rtu per net kwh. The higher rate in 1952 probably resulted from difficulties with the high pressure heater. A tube leak developed and, in the process of correcting the trouble, three high pressure heaters were out of service several weeks. Operating effi ciency during the interval was 4Vk per cent below normal.' The normal expec tation Is an annual heat rate oi 9950 Btu per net kwh. During early opera tion some difficulty was experienced in the regulation of throttle and reheat temperatures nesr maximum load oper ation. The source of the spray water had insufficient pressure to provide adequate desuperheating. A source of higher pressure was provided and spray nosxlea enlarged to correct the difficulty.

Design Considerations In Kedok Park's Powor System. By II A Decker, East
man Kodak Co. This paper presents the design con
siderations for the power plant equip ment In a highly specialized chemical plant producing photographic film and paper products. High pressure trailers and turbines are used to produce the steam required by the manufacturing plant and generate electrical power on a by-produet bails. The nature of the manufacturing processes requires that special attention be given to continuity of operation and plant cleanliness.
The installation of any tteam-generating equipment for a manufacturing plant is made primarily on basis of need (or additional steam and lor the re placement ol obsolete or worn out boil er*. The first eomideration is to get steam to the various buildings in the quantities ond at the pressures oeeded. This constitutes a problem in diatribu-

DREW STEAM LINE CORROSION CONTROL TREATMENTS ELIMINATE STEAM AND CONDENSATE LINE REPLACEMENTS
[' A leading food plant was constantly replacing condensate return lines that had failed. Drew Engineers determined the cause offailures to be carbon dioxide in the condensate.
For treatment, Drew SLCC waa recommended. This ; is a non-toxic material which does not taint the food
being processed in.the plant. A volatile alkali, Drew ^ SLCC corrected the condition quickly, by neutralizing " the carbon dioxide. In this plant, Drew treatment put
an abrupt end to costly maintenance.
In ether instances of steam and condensate line cor rosion, Drew Products such as SLCC-Q and SLCC-A are used, depending upon conditions. To prevent or eliminate water problems in your plant, you'll get results faster and more economically with tho Drew 5-point program
