Coal Flame database
This document describes the database of experiments performed using coal and methane combustion in the Cambridge Coal Burner (CCB). The permanent database has been moved to: https://doi.org/10.17863/CAM.96660.
Two series of experiments were produced:
- CCB1: no bluff body
- CCB2: with bluff body
Both cases have the same outer geometry, but series CCB2 is outfitted with a central bluff body to enhance flame stabilization and coal burnout.Cases with reacting flows are denoted RF, and non-reacting flow, by NRF.
The burner consists of a tube carrying the mixture of coal, methane, oxidizer and diluent (conditions listed below), surrounded by a swirling pilot of methane gas. Geometry files can be downloaded:
- Base geometry. For the CCB1 case, no bluff body is present.
- Extraction unit
