Incineration boiler

The customer

• Size: Medium-large company
• Sector: Conversion operator
• Country: United Kingdom

The Project

• Size: 100-120 man-hours
• Duration: 3-4 weeks

The Problem

• Uneven thermal performance on the boiler
• Potential thermal stress issues
• Fatigue analysis required according to industry Standards

Proposed solution

• Model combustion and fluid flow for different operation scenarios and fuels
• Assess thermal expansion for boiler tubes and tubesheets

The simulations

• Steady-state CFD thermal simulation for the waste combustion (CFD analysis)
• Stress calculation for thermally induced loads on mechanical elements (FE analysis)
• Fatigue post-processing for useful life estimation (FE analysis)

Project overall results

• Optimised tubesheets geometry for minimised stresses.
• Savings over £28,000 for the customer in prototyping and testing (estimate).
• Savings of more than 14 weeks in development time (estimate).
