Heat Rate Audit & Analysis of Thermal Power Plants

Introduction

The availability of Fuels required for Power Plants is reducing and their costs increasing rapidly. This gives rise to increase in the Cost of Generation of Electricity. But Electricity Regulators have to control the price of Electricity so that consumers are not stressed with High Costs. In addition, environmental considerations are forcing Power Plants to reduce CO2 emissions.

Under these circumstances, Power Plants are constantly under pressure to improve the efficiency of operating plants, and to reduce fuel consumption. In order to progress in this direction, it is important that Power Plants regularly audit their energy use in terms of the operating Plant Heat Rate and Auxiliary Power Consumption.

Energy Audit of Thermal Power, Combined Cycle, and Cogeneration Plants attempts to refresh the Fundamentals of the Science and Engineering of Thermal Power Plants and establishes its link with the Real Power Plant performance data through case studies, and further developing techno-economic of the Energy Efficiency improvement measures. This Course will rekindle interest in Energy Audits and Analysis of the data for designing and implementation of energy conservation measures on a continuous basis.

By maintaining the Heat Rate of a Generating unit or Desalination as a combined cycle at its optimal level, one is assured of the proper functioning of the unit. Furthermore, knowledge of the Heat Rate allows for the overall economic operation of the entire Power and Water System. The main goal of this course is to make Power and Desalination Plant more reliable, efficient and environmentally compliant. This requires personnel training on Operation Optimization of advanced equipment, condition monitoring and testing that are directed toward plant and personnel performance enhancement.

Objectives

By the end of the training, participants will be able to:

• Understand the major Aspects in GT, Boiler and Desalination Plant
