contains a drain‚ which removes contaminants and sediment from the water vessel‚ and a chimney‚ which allows heat to escape once it has passed through the water vessel. Boiler Configurations There are two main types of boilers: fire tubes and water tubes. In a fire tube boiler‚ heat is directed through metal rods that pass through the middle of the water vessel. The rods are arranged in banks so that the heat can pass through the vessel many times before escaping through the chimney.

Boiler systems are classified in a variety of ways. They can be classified according to the end use‚ such as foe heating‚ power generation or process requirements. Or they can be classified according to pressure‚ materials of construction‚ size tube contents (for example‚ waterside or fireside)‚ firing‚ heat source or circulation. Boilers are also distinguished by their method of fabrication. Accordingly‚ a boiler can be pack aged or field erected. Sometimes boilers are classified by their heat

Steam engines were the first engine type to see widespread use. They were first invented by Thomas Newcomen in 1705‚ and James Watt (who we remember each time we talk about "60-watt light bulbs" and the such) made big improvements to steam engines in 1769. Steam engines ¬powered all early locomotives‚ steam boats and factories‚ and therefore acted as the foundation of the Industrial Revolution. In this article‚ we’ll learn exactly how steam engines work.74 Steam Engine Operation The

ABSTRACT Television has been an excellent medium for entertainment and information ever since the invention of the electron scanning tube in 1923 by Vladimir Kosma Zworykin‚ who is considered the father of the modern television. With the conversion to digital format 1080i in 1998‚ there has been a boom in the production of different types and technologies for Televisions. A new generation of televisions has been developed‚ including liquid crystal display (LCD)‚ rear projection‚ and high definition
