Answer to Question #293630 in Mechanical Engineering for king

Question

: What do you mean by Steam generators or Boilers? How do we classify them? Also write its applications in various industries.

Answer 1

A boiler (also known as a steam boiler) is a closed vessel in which fluid (typically water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, such as cooking, water or central heating, or boiler-based power generation. Boilers (or more specifically steam boilers) are an essential part of thermal power plants.

Types of Boiler

1. Fire Tube Boiler
2. Water Tube Boiler

Types of Fire Tube Boiler

External furnace boiler can be again categorized into three different types-

1. Horizontal Return Tubular Boiler.
2. Short Fire Box Boiler.
3. Compact Boiler.

Types of Water Tube Boilers

There are many types of water tube boilers, such as

1. Horizontal Straight Tube Boiler.
2. Bent Tube Boiler.
3. Cyclone Fired Boiler.

Horizontal Straight Tube Boiler again can be sub-divided into two different types,

1. Longitudinal Drum Water Tube Boiler.
2. Cross Drum Water Tube Boiler.

Bent Tube Boiler also can be subdivided into four different types,

1. Two Drum Bent Tube Boiler.
2. Three Drum Bent Tube Boiler.
3. Low Head Three Drum Bent Tube Boiler.
4. Four Drum Bent Tube Boiler.

Applications of Steam Boiler

1. The applications of this boiler include the following.
2. These are used to generate power in steam turbines or engines.
3. These are used for various processes in process industries
4. These are used in houses or buildings in cool weather for generating a hot water supply
