Overview of Steam Boilers A steam boiler is a vessel that contains water and a heat source powered by oil‚ coal or gas. The boiler transfers heat from the heat source to the water vessel‚ thereby turning the water into steam. This steam exits the vessel through a pipe and is transported to another location where it can be used for cleaning‚ to power equipment‚ to provide heat or for a number of other functions. A closed boiler system is one in which 100 percent of the steam is returned to the vessel

undoubtedly proven crucial to our modern lives‚ without the monumental discoveries of the 18th and 19th century‚ we may not have had the opportunities to generate those advancements. In particular‚ the progress and development of iron and eventually steel‚ steam power and it’s multitude of uses‚ and the railway systems has truly defined the technological advancements of recent centuries. Body: Prior to the 18th century‚ the methods in place for producing iron were relatively rudimentary and ultimately inefficient

Questions: 1. One mole of a compound A‚ with vapor pressure 400mmHg at 50oC‚ mixed with 3 moles of compound B‚ with vapor pressure 480mmHg at 50oC to form a homogeneous solution. What is the vapor pressure of mixture at 50oC? XA =moles of A\total No. of moles XA =1\4 XB=3\4 Ptotal=PAoXA+PBoXB =400*1\4 + 480*3\4 = 460mmHg 2. Why should a distilling flask be filled not less than 1\3 filled or more than 2\3 full? This is to allow the liquid being heated room to expand as it turns

Steam Locomotives were first made in the 18th century. William Murdoch first made a prototype in 1784. An early working model was built by a steam boat pioneer John Fitch. Richard Trevithick (13 April 1771 – 22 April 1833) was a British inventor and mining engineer from Cornwall. Born in the mining heartland of Cornwall‚ Trevithick was immersed in mining and engineering from a young age. The son of a mining captain‚ he performed poorly in school‚ but went on to be an early pioneer in steam-powered

8.2.1 (iv) Fractional Distillation of Crude Oil By Blake Turner – Year 11 Fractional Distillation of Crude Oil Introduction Crude oil is the term for "unprocessed" oil‚ the stuff that comes out of the ground. It is also known as petroleum. Crude oil is a fossil fuel‚ meaning that it was made naturally from decaying plants and animals living in ancient seas millions of years ago -- most places you can find crude oil were once sea beds. Crude oils vary in colour‚ from clear to tar-black‚

I. Introduction Fractional distillation is the separation of a mixture into its fractional parts that entails many concurrent vaporization-condensation cycles. This works because of different boiling points of individual substances. The temperature of the fractional distillation column decreases as its length increases. A higher boiling point component condenses on the column and returns to the solution whereas the lower boiling point component passes through the column and is collected in a receiver

and integration in CDU ’. The main report is divided into 4 sections. To start with‚ the first Section is a basic introduction to Crude distillation unit‚ its process and products. Heat exchange is among the most important activity for crude distillation units. The 2nd part of the report focuses on this heat exchange process occurring in the crude distillation unit of Guwahati refinery. Necessary data regarding all the heat exchangers has been provided in a tabular manner to make understanding
