A new development for briquette use is as a source of dried brown coal to produce pulverised, or micronised, coal as an industrial fuel. In this form briquettes can be used in boilers and other industrial applications to produce flames with a high radiant output and with the operating flexibility of oil or gas flames (Allardice et al., 1989).
