Fuel Gas Waste Heat Boiler

At very short notice, our client engaged DIALOG Fitzroy to provide a Fuel Gas Waste Heat Boiler.

The replacement unit included the economiser assembly, inlet, outlet, vent and drain piping, to replace the existing economiser assembly. All of this was required to be achieved in just 14 weeks to meet the planned shutdown timeframe.

Apart from the very tight delivery timeline, one of the primary challenges on this project was ensuring the new economiser would fit in the space after the existing economiser was removed. This was due to the fact that existing economiser was operating at 300°C, which had caused its outside body and flange faces to warp during operation, hence deviating from its cold position dimensions.

Project Requirements

Mechanical Design and Engineering
Procurement
Fabrication
Insulation
Installation

Services Provided

3D laser scanning of the assembly
Finite Element (FEA) and Computational Fluid Dynamics (CFD) analysis to determine what the dimensions would be when the economiser assembly is in its cold position.
Creation of Fabrication/Desing drawings of the existing economiser assembly which had contradictory information and were not “as-built” at the time of the existing economiser installation.
Short timeline procurement of components based on drawings and to meet short fabrication timeline
Fabrication painting, insulation and installation of the Fuel Gas Waste Heat Boiler economiser assembly, inlet, outlet, vent and drain piping, to replace the existing economiser assembly.
