Fire tube boiler designing Fire tube boilers operate by sending combustion/flue gas by using a combination of straight tubes flanked by trouble held in identical vessel. Often identified by the variety of passes used (say for example a 3-pass or 4-pass fire tube boiler)‚ this refers to the variety of times combustion gas flows the capacity of the pressure vessel mainly because it transfers heat on the water. A wet-back fire tube boiler utilizes a water cooled publish zone (end closure). A dry-back

Orsat Gas Analysis Experiment I. Objectives To analyze the dry exhaust gas (DEG) from a combustion system using the Orsat apparatus. II. Apparatus As shown in figure‚ the Orsat apparatus consists of a water-jacketed 100-m1 burette B connected at its top to a glass manifold M and at its bottom to a leveling bottle L. The glass manifold M is connected to three reagent bulbs called pipettes P1‚ P2 and P3 via three cocks C1‚ C2 and C3. Each tube is filed with its own absorbing chemical solution:

BIOL 140 Lab—The Chemical Composition of Cells Name ____________________________ I) Introduction All cells contain four major types of macromolecules: carbohydrates‚ lipids‚ nucleic acids‚ and proteins. In today’s lab‚ we will be studying three of the four-proteins‚ carbohydrates and lipids. Various chemical tests can be used to detect the presence of each of these molecules. Most of the tests involve a color change visible to the eye. If a color change is observed‚ the test is considered positive

Chemical Bonding Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms ... a chemical bond. The two extreme cases of chemical bonds are: Covalent Bonds Covalent chemical bonds involve the sharing of a pair of valence electrons by two atoms‚ in contrast to the transfer of electrons in ionic bonds. Such bonds lead
