INTRODUCTION 1-1. PURPOSE The purpose of this manual is to provide information and guidance on the installation operation and maintenance of . Army Central Boiler Plant equipment. Efficient plant operation becomes more important with each increase in the cost of fuel and equipment. The Central Plant operator has an important job in achieving and maintaining maximum efficiency of plant operation. The information and guidance in this manual should be reviewed as a first step toward achieving efficient plant operation. 1-2. CENTRAL BOILER PLANTS The primary purpose of a Central Boiler Plant is to economically produce energy for distribution. This energy may be in the form of steam hot water or occasionally compressed air or electric power. A distribution system is necessary to carry this energy to buildings hospitals kitchens and laundries where it is used for heating coding process sterilization and production of domestic hot water. Condensate or hot water is returned to the Central Boiler Plant where it is reheated in a boiler and returned to the distribution system for recycle. a. Types of Central Boiler Plants. Energy for heating or process use is generally produced in one of five forms Low Temperature Water LTW up to 250 E less than 160 psig MTW 251 E to 350 F HTW 351 Fto450 F LPS up to 15 psig HPS above 15 psig Medium Temperature Water High Temperature Water Low Pressure Steam High Pressure Steam The type of Central Boiler Plant built depends upon the requirements of the specific installation. For applications involving only space heating and domestic water a low temperature water plant is generally sufficient. If steam is required for large process loads or electric generation a steam plant must be constructed. For most other installations an economic evaluation must be performed to compare the costs of a high temperature water system to those of a steam system. Such an evaluation usually shows the high .
