Introduction to maintenance engineering

Image
Book Information:  The book provides a good foundation for a new graduate to work as a maintenance engineer and to build a career by moving through the ranks of junior‐ and middle‐level management responsible for maintaining the various types of engineered objects. It can also be used as a  reference book by practicing maintenance engineers/managers to understand the modern knowledge‐based approach to maintenance. The book can also be used as a starting point for researchers in maintenance. Table of  Contents: 1). An Overview 2 ). Basics of Reliability Theory 3). System Degradation and Failure 4). Maintenance – Basic Concepts 5). Life Cycle of Engineered Objects 6). Technologies for Maintenance 7). Maintainability and Availability 8). Models and the Modeling Process  9). Collection and Analysis of Maintenance Data

Types of Boilers

Image
  Types of Boilers Boilers are divided in Two main Types Fire Tube Boilers Water Tube Boilers Fire Tube Boilers A steam boiler in which the products of combustion pass through the tubes, which are surrounded by water. Advantages Easy to Clean Relatively inexpensive Compact in size Well suited for industrial applications Operates with oil, gas or solid fuels Disadvantages   Not suitable for pressure higher than 30 bar Limitation for high-capacity steam generation (upto12,000 kg/hour) Water Tube Boilers A steam boiler in which the water passes through the tubes and products of combustion surround the tubes. Advantages   Available in larger capacities (4,500 – 120,000 kg/hour) Able to handle higher pressures Faster response to changing loads Provide an adequate furnace to ensure complete combustion. Disadvantages   High initial capital cost Cleaning is difficult due to design structure No commonality between tubes Bigger in physical size Lower tolerance for water quality and needs water t
