Paper: Heat Rate Improvements and Limitations Based on EPA’s Block Strategies
The installation of additional AQCS such as that required by regulations including BART, ELG, MATS, etc. will also increase the heat rate of units compared to its heat rate prior to installation due to the use of auxiliary power. Continue reading
Paper: Conversion of Coal-Fired Electric Generating Units to Natural Gas-Fired Units
Historically, natural gas supply has been consistent in quality and heating value throughout the United States. Gas properties have also been consistent, with slight variations, making the risk of a significant error in engineering and design of gas-fired equipment quite low. Table 1offers a representative fuel analysis for natural gas. Continue reading
Article: Zero Liquid Discharge Effluent Compliance Strategies for FGD Wastewater
October 20, 2015 – The October 2015 issue of Industrial WaterWorld featured the article “Zero Liquid Discharge Strategies for Compliance with Proposed Effluent Guidelines for FGD Wastewater.” Read the article online. Additional details from the case study are available in the … Continue reading
Paper: Natural Gas Conversion of Existing Coal-Fired Boilers
ABSTRACT An increasingly stringent and uncertain regulatory environment and falling natural gas prices have made converting existing coal-fired steam-generating boilers to natural gas firing more and more attractive. This paper provides a general assessment from a sampling of projects that … Continue reading

Paper: Water Consumption of Cooling Towers in Different Climate Zones
ABSTRACT Cooling towers are widely used across a range of industries and represent the largest reuse of water in industrial and commercial applications. While continually recycling water, cooling towers loose significant inventory through evaporation and blowdown. The local climate strongly affects the efficiency of … Continue reading
Paper: Equivalent Mass, Stiffness, and Loading for Off-Centre Missile Impact Evaluations
ABSTRACT For evaluation of the structures against missile impact loads, including buildings located at nuclear power plants, it is usually desirable to idealize the structure with a single degree of freedom (SDOF) system. It is therefore convenient to introduce certain transformation … Continue reading
Paper: Comparison of Approaches for Evaluation of Accidental Load Drops
ABSTRACT An accidental load drop during load handling could impact the safety of the nuclear plant structures or safety-related equipment and cause inadvertent criticality, or loss of safe shutdown equipment. In this paper, available approaches for evaluation of the structural … Continue reading
Paper: Relative Movements for Design of Commodities Running Between Safety-Related Structures
ABSTRACT In nuclear power plants a large number of commodities such as piping, HVAC, conduits, and cable trays communicate between adjacent buildings. Such commodities supported by two adjacent buildings can be subjected to significant relative movements due to settlement … Continue reading
