Outline Of Boiler Design Why we need to design?
• Safety
• Mathematical Modeling can be done.
• Predicting response of system to input and surrounding.
• Save cost of trial and error.
History:
• Development of Boilers: from small unreliable boilers to today’s mega boilers.
• The important milestones in designing and how they improved safety and efficiency of boilers.
Pre-requisites in a Boiler Design:
• Input needed to design a boiler
• Output desired
• Safety considerations
• Constraints (mechanically)
• Cost Restrictions
General Design Procedure of Boiler
• Type of Boiler to be designed (fire tube, water tube etc) according to available resources and desired output.
• Calculations associated with boiler design.
• Software available to calculate the necessary parameters.
• AutoCAD/Pro-V or other designing software for Boilers.
• Types of Grates and Furnaces used according to fuel used and cost (IMP: mention biomass as fuel and also requirements of boiler when
fuel is biomass)
Manufacturing Techniques:
• Materials used according to safety and cost constrains
• Types of Joining (welding, riveting etc) used for different applications (high pressure areas, areas exposed to steam etc)
• Insulation used for piping and storage drum.
Types of boiler accessories and mountings (provide links)
