An Experimental and Numerical Investigation on the Thermal-Hydraulic Performance of Double Notched Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The double notched (DN) plate is commonly used in rotary air preheaters, but relevant investigations are rare. Thus, thermal-hydraulic performances of the DN plate are investigated in this paper. ...
Numerical Investigation of the Effects of Swirl-Vane Angle and Particle Size on Combustion and Flow Characteristics in a Vertical Cyclone Barrel
Publisher: ASCE
Abstract: The cyclone-fired boiler has become a very competitive boiler type for utilizing coal with a low ash melting point and high alkali. Because of the higher combustion intensity in the cyclone barrel, good flow and combustion ...
Effects of Lignite Predrying Degree on the Combustion and NO Generation in a 600-MW Lignite-Fired Boiler
Publisher: ASCE
Abstract: Previous studies have shown that predrying can improve lignite combustion performance and lignite-fired boiler efficiency. This paper numerically investigated the effect of the lignite predrying degree on the combustion ...
Effect of Volatile-Char Interaction on Nitrogen Oxide Emission during Combustion of Blended Coal
Publisher: American Society of Civil Engineers
Abstract: Utilization of blended coal has been a great issue due to the increasing off-specification coals received in power plants, while the reduction of nitrogen oxide is also attracting extensive attention in China. This study ...
Comparative Study of Three Modes of Flue Gas Treatment for Power Plants
Publisher: American Society of Civil Engineers
Abstract: Flue gas treatment systems have been widely installed in power plants to recover the remaining energy from the exhaust flue gas and to address pollutant emissions by heating the cleaned flue gas. In this study, three modes ...
Thermodynamic Analysis and Case Study of a New Lignite-Fired Power Plant Using Solar Energy as Drying Heat Source
Publisher: ASCE
Abstract: Lignite usually has a high moisture content and low calorific value, and should be predried before combustion to enhance power generation efficiency. Steam extracted from steam turbine and boiler exhaust gas are often ...
Numerical Investigation on Cofiring Characteristics of Biomass Syngas and Coal in a 660-MW Tower Boiler
Publisher: ASCE
Abstract: Cofiring biomass syngas (BS) with pulverized coal under the oxy-fuel condition is a promising technology, which could encourage the utilization of biomass energy and reduce the emission of greenhouse gases. To investigate ...
NOx Formation Characteristics for Cocombustion of Rice Husk and Coal at High Temperature
Publisher: ASCE
Abstract: The cocombustion of biomass and coal has the potential to reduce NOx emissions at high temperatures. In this study, an experimental investigation was conducted on a drop-tube furnace to investigate NOx formation characteristics ...
Oxyfuel Cofiring Characteristics of Biomass with Ultralow Volatile Carbon-Based Fuels
Publisher: American Society of Civil Engineers
Abstract: Biomass from agricultural production is a renewable energy source with a high-volatile content. Semicoke (SC) and gasification residual carbon, which are ultralow volatile carbon-based fuels (LVFs), are by-products of the ...
Numerical Study on Coal–Sludge Cocombustion Characteristics and NOx Emission Behaviors in a 330-MW Wall-Fired Boiler
Publisher: ASCE
Abstract: Cofiring sludge with coal based on existing power plants is a promising method to realize harmless recycling treatment for sludge disposal. However, the influences of sludge addition on NOx emission are still controversial. ...
