Abstract:

This document is a profile for the project titled 'Advanced Near Burner Flame Diagnostics For Ignition And Stability Studies On Full Scale Pulverised Coal Flames'.

The overall aim of the project is to improve the simulation of the near burner region of flames by CFD models, and to devise techniques whereby ignition processes in the vicinity of the flame holder and the flame structure immediately downstream can be assessed for individual flames in large pulverised coal fired furnaces. Specific project objectives are:

To establish a technique whereby the near burner region, and in particular the ignition regions of the flame, can be observed and recorded by means of a high-speed video probe.

To demonstrate this technique in plant trials, using existing test activities to assess factors such as the impact of local operating conditions and coal quality on burner stability and near-burner flame structures.

To assess the capability of existing CFD codes to simulate the observed processes occurring in the near burner region (with specialised laboratory coal testing at ICSTM to assess coal properties).

To investigate the potential differences between single burner and multi-burner furnace performance.

To increase the level of confidence in the use of CFD modelling for the simulation of burners and furnaces.

To develop the equipment and processing methods for industrial use as a specialised diagnostic technique to assist in plant optimisation of individual burners in a multi-burner furnace or in recording the localised flame structures in the near burner region to aid in the development of improved burner designs.
