An Investigation of Iron Formation on the Furnace Floor

This report is consisted of three parts: the study of chemical reactions of iron compounds in the coal combustion, solutions for the reduction of iron accumulation on the furnace floor and instruments for the detection of the problem. It is found that most iron compounds remain in their original form without taking chemical reactions. Two possible ways can be used to solve the problem. One way is to burn pyrites so that they will become flying ashes. Another way is to melt the slag completely. Details of the methods are given in the report. In the study of instruments, an infrared gas analyzer is proposed for the detection of gas composition, a tungsten-tungsten rhenium thermocouple for the temperature measurement and a modified transformer for the detection of iron accumulation

DISCOVERY OF LAGRANGIAN EQUATION FOR FLUID MECHANICS

<p>ABSTRACT This paper is intended to build a connection between dynamics and fluid mechanics. Since Lagrangian equations are very useful tools in dynamics now it is discovered that it can be also used in fluid mechanics, so connection can be built through this equation... Here, the lagrangian equation is derived from the momentum equation in fluid mechanics, and then the equation is applied to three different coordinates, Cartesian, cylindrical and spherical. Certainly the application of the equation is not limited to these three different coordinates. This is just for illustration. Many applications are expected.</p
