  • Modern Steam Generators
    4 MODERN STEAM GENERATORS 4.1 Introduction Boiler is a container into which water is fed, and by the application of heat, it is evaporated into steam. In early designs, the boiler was a simple shell with a feed pipe and steam outlet, mounted on a brick setting. Fuel was burnt on a grate within the setting and the heat so released was directed over the lower shell surface before most of it went out. Soon the designers realized that heating a single shell is inefficient and it was necessary to bring more of water into close contact with heat. One way, is to direct flue gases through tubes in the boiler shell. Such a '“fire-tube design’ not only increases the heating surface but also distributes area of steam formation more uniformly. Second way is water-tube design. It consists of one or more relatively small drums with number of tubes in which water-steam mixture circulates. Heat flows from flue gases outside tubes to the mixture. Thus sub-division of pressure parts make possible construction of large capacity and high pressure boilers. Fire-tube boilers and simple water-tube boilers are described in detail in chapter-8 of volume-l. Fire-tube boilers are limited to a maximum design working pressure of 25 bar and steam generating capacity of 25 tonnes per hour. Conventional water-tubes boilers work upto steam pressures of about 70 bar and 250°C superheat with a steam generating capacity of 40 tonnes per hour. Shell or fire-tube boilers are cheaper than water-tube boilers but they are suitable for low pressures and low output.

  • Unit 1 a Steam Boiler Or Steam Generator Is a Closed Vessel In
    Unit 1 A steam boiler or steam generator is a closed vessel in which water is heated, vaporised and converted into steam at a pressure higher than the atmospheric pressure. The heat energy required for steam generation is produced by burning fuel in the furnace. INDIAN BOILER REGULATION (IBR, Act 1923): Steam boiler means any closed vessel exceeding 22.75 litres (other pressure vessel) in capacity and which is used expressively for generating steam under pressure. It includes any mountings or other fittings attached to such a vessel, which is wholly or partly under pressure when steam is shut off. Functions The function of a steam boiler or generator is to convert chemical energy of a fuel by combustion into heat and transfer this heat to water and thus to produce the steam. 1.2 Applications of Steam Generated The steam thus generated is used for: i. Power Generation: Mechanical work or electric power may be generated by expanding steam in the steam engine or steam turbine. ii. Heating: The steam is utilized for heating the residential and industrial buildings in cold weather and for producing hot water for hot water supply. iii. Utilisation of Steam: For industrial processes such as for sizing and bleaching etc. in textile industries. Steam is also used in many other industries like Sugar Mills and Chemical Industries. Boilers Classification: There are a large number of boiler designs, but boilers can be classified according to the following criteria: 1. According to Relative Passage of water and hot gases: 1. Water Tube Boiler: A boiler in which the water flows through some small tubes which are surrounded by hot combustion gases, e.g., Babcock and Wilcox, Stirling, Benson boilers, etc.

    APPLIED THERMAL ENGINEEING 15ME52T UNIT-II STEAM BOILERS Steam generators are used to produce high pressure superheated steam. A steam generator is complex combination of economizer, boiler, super heater, reheater and air preheater. Boiler is a portion of the steam generator but it is used to mean the whole steam generator. DEFINITION OF BOILER A steam generator or a boiler is a closed steel vessel which generates the steam by transferring heat, produced by burning of fuel, to water. FUNCTION OF BOILER Following are the functions of steam boiler: 1. To transfer the heat produced by combustion of the fuel to water to generate the steam. 2. To supply the steam at the required constant pressure either dry or superheated. APPLICATION OR USES OF STEAM BOILERS (APPLICATION OR USES OF STEAM) Applications Steam boilers are as follows: (1) POWER GENERATION: Mechanical power can be generated by expanding steam either in a steam engine or in a steam turbine. If the engine/turbine is coupled to a generator, electric power can be generated. (2) HEATING: Steam is used in winter air conditioning of residential and industrial buildings. It is also used to heat water for hot water supply. (3) INDUSTRIAL PROCESSES: Steam is used for certain industrial processes such as sizing, bleaching etc., in textile mills, sugar factories, breweries etc., CLASSIFICATION OF BOILERS (1) BASED ON FLOW OF WATER AND HOT GASES (A) Fire tube boilers (B) Water tube boilers (2) BASED ON USE (A) Stationary boiler (B) Mobile boiler (3).
