Pressure distribution across the equipment clusters of plant TP1

Environmental remediation · United States · 2025–2026

Optimizing a dioxin soil treatment system — TP1

Several fans in series across branching ducts: pressures depend on each other, so fixing one cluster relocates the problem.

Full gas-path flow analysis of an HRSG

The diffuser duct, silencer and damper bend the flow right before the finned tube bank: part of the bank takes far too much flow while the rest works below capacity.

Diagnosing maldistribution in an overhead condenser

An uneven distribution header floods some tube rows and leaves the rest as dead zones; local corrosion there sets the retubing interval of the whole unit.

Optimizing an ozone DeNOx system in a wet scrubber

The cooling spray curtain and the ozone injection point constrain each other: mixing, residence time and the reaction temperature window pull the injector position in three different directions.

Thermal power · Vietnam · 2025

A burner evaluation tool for NH₃ co-firing

Ammonia co-firing cuts CO₂ but readily raises NOx and approaches combustion-safety limits; these three constraints surface only after installation, so simulation must resolve them first.

Cement · Vietnam · 2025

Choosing the alternative-fuel injection points for a cement calciner

27.5 t/h of alternative fuel must burn out inside the calciner; feeding it at the wrong point raises CO and lets fuel fall back into the kiln.

Ductwork and exhaust fan for a charcoal pyrolysis plant

Running a fourth furnace lengthens the batches; the gas balance shows the exhaust fan short of flow in every high-load case.

Diagnosing the cold-air flow in a blast freezer

The slowest tray takes 167 minutes, twice the fastest — most of the cold air goes around the trays straight back to the evaporator.

Condenser layout for a data-centre cooling system

Downward louvers trap the lower tiers' warm air, causing the condensers to draw back their own exhaust when it is already 41 °C outside.

Energy efficiency of a spray dryer & cyclone train

The spray dryer consumes most of the plant's thermal energy; the cyclone train suffered high pressure loss, poor separation and rapid, uneven erosion.

Settling the SNCR injection layout before installation

The SNCR reaction works only within a narrow temperature band, yet the injector positions must be fixed before installation, and a wrong choice means costly correction on site.

Wind Tunnel & Wind Ring — design optimization

A wind tunnel's output is the flow quality in its test section, which depends on dimensions fixed at the outset; correcting them afterwards means cutting and re-welding the tunnel body.
