Coal Flame database
This document describes the database of experiments performed using coal and methane combustion in the Cambridge Coal Burner (CCB). 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:
Operating conditions excel file. The co-flow outer rate is 240 slpm, the outer diameter 122.94 mm, inner diameter of 44.45 mm.
Air flow: alumina PIV: RF = reacting, NRF = non-reacting (CCB1)
High speed PIV: RF = reacting, NRF = non-reacting
OH PLIF and Mie: CCB1
