A **coke oven battery** is an array of tall, narrow refractory-lined ovens in which coking coal is heated in the absence of air to produce metallurgical coke for the blast furnace. The process produces large quantities of by-product gas and tar, captured by the by-product plant.

## Cleaning targets

- **Coke-side pushing-emission baghouse (PEC)** — captures dust released when hot coke is pushed from the oven into the quench car
- **Charging emissions baghouse** — dust released during coal charging
- **By-product gas dust collection** — particulate in the raw coke-oven gas before processing
- **Stack-line cleaning** for waste-heat recovery boilers

## Sonic-horn duty

[Sonic horns](/glossary/sonic-horn) on PEC and charging baghouse hoppers prevent the sticky coal-and-coke-dust mix from bridging — a particularly hard duty because of the cohesive, partly-tarry deposit character.
