http://www.coalpowermag.com COAL POWER en-us 2012 Sat, 4 Feb 2012 18:48:22 EST The hazards of coal dust accumulation in power plants are familiar to coal-fired plant operators. Operators of plants that burn Powder River Basin coal are particularly aware of necessary housekeeping and fuel-handling practices, but any plant that allows excessive amounts of coal dust to accumulate is playing Russian Roulette with its staff and equipment.... http://www.coalpowermag.com/ops_and_maintenance/373.html Wed, 1 Feb 2012 0:00:00 EST Creating a landfill to hold dry boiler ash is a challenging proposition these days. There's more to the project than you might imagine, as you'll learn from this article about the development of a typical new ash landfill.... http://www.coalpowermag.com/ops_and_maintenance/374.html Wed, 1 Feb 2012 0:00:00 EST Rules requiring removal of combustible dust from the workplace will undoubtedly improve worker safety and health. A survey of equipment suppliers finds a variety of dust collection systems are available to meet just about every dust collection need in the power house.... http://www.coalpowermag.com/ops_and_maintenance/378.html Wed, 1 Feb 2012 0:00:00 EST A Romanian lignite-fired power station wanted to minimize the operating cost of the flue gas desulfurization (FGD) system by placing the booster fans in the "wet position," between the wet FGD scrubber and the wet stack, where they would consume significantly less power. A number of combined environmental effects must be considered in this design.... http://www.coalpowermag.com/ops_and_maintenance/360.html Thu, 1 Dec 2011 0:00:00 EST Pulverizers prepare raw fuel for burning by grinding it to a desired fineness and mixing it with the just the right amount of air before sending the mixture to boiler burners for combustion. Part I of this three-part report examined the essentials of pulverizer design and performance; Part II discussed the importance of fuel fineness. This final article discusses the importance of air and fuel measurement.... http://www.coalpowermag.com/ops_and_maintenance/361.html Thu, 1 Dec 2011 0:00:00 EST When sootblower operation frequency is too high, a plant risks losing power generation from tube leaks; but when sootblower frequency is too low, there is a risk of boiler pluggage. Intelligent sootblowing finds the right balance between tube erosion and plant economic operation.... http://www.coalpowermag.com/ops_and_maintenance/364.html Thu, 1 Dec 2011 0:00:00 EST Several states have already instituted mercury emission limits in expectation of tightening mercury emission rules that will require reductions of up to 91%. Coal-fired plants searching for an economical way to meet the new limits may need to look no further than replacing their baghouse filter elements.... http://www.coalpowermag.com/ops_and_maintenance/340.html Sat, 1 Oct 2011 0:00:00 EDT Pulverizers prepare the raw fuel by grinding it to a desired fineness and mixing it with the just the right amount of air before sending the mixture to boiler burners for combustion. In Part I of this three-part report, we examined the essentials of pulverizer design and performance.  In the second part, we discuss the importance of fuel fineness. In the final article, we will discuss the importance of air and fuel measurement.... http://www.coalpowermag.com/ops_and_maintenance/349.html Sat, 1 Oct 2011 0:00:00 EDT Utilizing engineering ingenuity and today’s developing computational fluid dynamics tools, a new classifier design is now available that significantly improves fineness from pulverizers without the heavy costs associated with dynamic classification or any downsides on pulverizer capacities, maintenance, and parasitic power.  Instead, operational flexibility and improved emission control options are enhanced.... http://www.coalpowermag.com/ops_and_maintenance/350.html Sat, 1 Oct 2011 0:00:00 EDT Pulverizers prepare raw fuel by grinding it to a desired fineness and mixing it with the just the right amount of air before sending the mixture to boiler burners for combustion. In Part I of three parts, we'll examine the essentials of pulverizer capacity, what should be done after a coal pulverizer fire or other incident, and how to tune up pulverizer performance. In future articles we'll discuss measuring pulverizer performance and performance optimization.... http://www.coalpowermag.com/ops_and_maintenance/329.html Mon, 1 Aug 2011 0:00:00 EDT
