Abstract:

The operation and control of Central Heating Plants CHPs are important factors in maintaining the readiness of U.S. Army installations. Aging CHPs often experience increased interruptions, maintenance difficulties, and inefficient operation. As fuel costs increase, there is a growing need to take advantage of new, emerging control technologies. Microprocessor-based controls can provide opportunities for increased reliability, enhanced safety, better performance monitoring, and cost reduction. However, upgraded control systems cannot compensate for a boiler in poor mechanical condition. Any proposed control systems upgrade must be preceded by a mechanical assessment of the boiler. These CHP control guidelines can help installation personnel develop budgetary-cost proposals to upgrade gasoil-fired boiler controls for gasoil-fired steam or high temperature hot water HTHW systems. These general guidelines provide basic information to evaluate the feasibility of upgrading boiler control systems, and a methodology for developing budget proposals. Judgement is required to develop designs for specific unit and site characteristics, boiler safety codes, and local regulatory requirements. These guidelines do not eliminate the need for competent professional engineers to finalize assessments of existing conditions, to develop a plant control system design that meets existing and new requirements, and to evaluate alternative contractor proposals.
