title: "Sinter plant"
description: "A sinter plant agglomerates iron-ore fines, coke breeze and flux on a moving sinter strand into porous sinter cake that can be charged to the blast furnace. Sinter is the primary iron-bearing feed at most integrated steelworks. The off-gas system carries dust loaded with iron oxides, alkali salts and unburned carbon, and is cleaned by ESP followed by baghouse on modern plants."

A **sinter plant** agglomerates iron-ore fines, coke breeze and flux on a moving sinter strand into porous sinter cake that can be charged to the blast furnace. Sinter is the primary iron-bearing feed at most integrated steelworks. The off-gas system carries dust loaded with iron oxides, alkali salts and unburned carbon, and is cleaned by [ESP](/glossary/electrostatic-precipitator) followed by [baghouse](/glossary/baghouse) on modern plants.

## Cleaning challenges

- **Sinter strand ESP** — heavy iron-oxide dust load, with episodic alkali-rich spikes
- **Main exhaust filter** — fine iron-oxide dust accumulates in hoppers
- **Cooler waste-heat boiler** — fouls when present, see [waste-heat boiler](/glossary/waste-heat-boiler)
- **Coke-side dust collection** — coke breeze and fines

## Sonic-horn fit

[Sonic horns](/glossary/sonic-horn) on sinter-plant ESP hoppers and baghouse compartments are routine specifications, particularly on European and East Asian steelworks where particulate-emission limits are tight.
