Boiler Basics Design and operation A boiler is an enclosed vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or steam. The hot water or steam under pressure is then usable for transferring the heat for the steam requirements of process industries or for power generation. Combustion boilers are designed to use the chemical energy in fuel to raise the energy content of water so that it can be used for heating and power applications. Many fossil

EXPERIMENT 3 MARCET BOILER 1.0. OBJECTIVE • To obtain a relationship between the pressure and temperature of saturated steam‚ in equilibrium with water‚ at all pressure between atmospheric and 10 bar (150 lb/in2). • To compare between calculated values from experiment data to the data obtained from steam table for vfg and hfg . 2.0. THEORY Thermodynamics is defined as a study related to the transfer of heat and work between a system and the surrounding‚ undergoing

circulation boiler was first introduced by La-Mont in the year 1925 which is used in Europe and America. This is a modern high pressure boiler (water tube type steam boilers) working on forced circulation system. Working principle of La Mont Boiler The image shows the flow circuit of La Mont Boiler. I will explain working of each and every part in La Mont boiler one by one. Steam separator drum The la Mont boiler consists of a steam separator drum which is placed wholly outside the boiler setting

The Kinetic Theory of ideal gases - It is employed to express quantitatively the ideal gas model. Postulates: 1- A gas consists of molecules of mass (m) and diameter (d). 2- Molecules move continuously and randomly. 3- Molecules are treated as points‚ having no volume 4- Molecules collide with each other‚ changing direction and velocity. 5- Collisions are elastic (no loss of translational energy) no potential energy of interaction between them. Derivation of the ideal gas equation
