Understanding Performance through CFD Modeling – Boilers with Dual Lower Arches

When examining boiler performance deficiencies, problems can often be traced to factors outside of the furnace, such as fuel quality. But sometimes the issue is the furnace itself. Jansen uses computational fluid dynamics (CFD) modeling to investigate performance improvements that can be realized through air system upgrades, furnace modifications, or both. A furnace design concept […]

Don’t Heat the Sky! Maximizing Heat Capture In Boiler Systems.

New, larger economizer ready to be installed in Plymouth, NC. Old economizer in the foreground. Combustion efficiency and heat capture efficiency are two important factors to consider when analyzing a boiler’s overall operating efficiency. Combustion efficiency relates to how effectively a boiler furnace and combustion system is able to combust the fuel it is firing.
