Application:

Ashoka provides industrial steam generation boilers that are used for steam process applications in industries such as sugar plants, pulp & paper, rice mills, chemical and food industries etc. These industrial boilers are designed keeping number of factors in mind, like steam generation capacity, exit pressure of steam, type of construction, fuel type, and others. These can be classified in various types such as:

• AFBC Boilers
• Multi Drum Boilers
• Single Drum Boilers OR Bi-drum Boilers
• Dumping Grate Boilers / Travelling Grate Boilers
  
  

Supply Range:


Ashoka supplies industrial boilers in following ranges:

• Capacity of Steam production, from 5 MT to 175 MT
• Pressure, from 10 Kg/cm2 to 110 Kg/cm2
  
  

Type of Fuels Used:

Different types of fuels can be utilized for firing of the boilers, and the use depends upon the availability as well as economic feasibility of the fuel. Cane Bagasse, Paddy Husks, Wood Chips, Goundnut Shell, Saw Dust, Cocoa Shell, Coal, Lignite etc. are some of the normally used fuels.
