Some of these pollutants are specific to the type of fuel or is part of the combustion process or related to the design and configuration of the plant. This article highlights the major pollutants discharged from the power plant. Carbon Dioxide (CO2) CO 2 was thought of as a pro...http://www.brighthub.com/engineering/mechanical/articles/25424.aspxSun, 08 Feb 2009 13:59:04 GMTb133e95a-c263-4882-8f2a-b24547eff78e:25424johnzactrubaGas Turbines are one of the most efficient equipment for converting fuel energy to mechanical energy.

Edison. 20 % of all the electricity we use is for lighting. Energy savings in lighting will go a lo...http://www.brighthub.com/engineering/mechanical/articles/23879.aspxTue, 27 Jan 2009 22:36:52 GMTb133e95a-c263-4882-8f2a-b24547eff78e:23879johnzactrubaThe boiler generates high pressure steam by transfering the heat of Combustion in various heat transfer sections. This part of the article series briefly describes the flow and arrangement of the heat transfer sections in a boiler. In line diagrams help make the concept clear. The Basics. Volume of one unit mass of steam is thousand times that of w...http://www.brighthub.com/engineering/mechanical/articles/24054.aspxThu, 29 Jan 2009 00:42:56 GMTb133e95a-c263-4882-8f2a-b24547eff78e:24054johnzactrubaBoilers burn coal to produce steam. Burning coal involves fuel preparation, providing the necessary combustion air and removal of the flue gases and ash. What are the main elements of the Combustion system in a large power plant boiler? Read this article to find the answers. Coal System Coal received from the mines is stored in the coal yard ad...http://www.brighthub.com/engineering/mechanical/articles/54252.aspxFri, 30 Oct 2009 15:09:47 GMTb133e95a-c263-4882-8f2a-b24547eff78e:54252johnzactrubaA practical and simple method for calculating the efficiency of coal fired boilers is given in this article. Practical assumptions are used to simplify the otherwise elaborate calculations of the Boiler test codes. The ASME method for Boiler Efficiency Calculation PTC 4 is elaborate and requires many input data points, measurements, and samples.
