ABSTRACT This experiment was carried out to determine the relationship between the pressure and the temperature of saturated steam in equilibrium. Besides that this experiment was also done to demonstrate the vapor pressure curve. The marcet Boiler was used for this experiment. When the pressure increases‚ the temperature also increases. Therefore‚ the relationship of pressure and temperature is directly proportional. The derived formulae and the data were used to calculate the slope. The dT/dP

BOILER OPERATION. Description of boiler operation SOFTENER: Function of softener is softening the hard water. This is because water supplied is hard water since it contains a lot of calcium‚ magnesium or other minerals. Water hardness Mg/L Soft water ≤ 17.1 mg/L Grey zone between soft and slightly hard water 17.1-60 mg/L Moderately hard 60-120 mg/L hard water 120 - 180 mg/L Very hard water ≥180 mg/L Hard water causes two problems such as 1.

Aim: To study the construction and working of various boiler mountings and accessories. Theory: A boiler is defined as a closed vessel in which steam is produced from water by combustion of fuel. Also defined as “A combination of apparatus for producing‚ furnishing‚ or recovering heat together with the apparatus for transporting the heat so made available to the fluid being heated and vaporized.” Classification of Boilers : The boilers may be classified according to following criteria: 1.
