Abstract

An alcohol-burning fire includes a novel design of burner (12) for the combustion of a liquid fuel such as bioethanol. The burner comprises a longitudinally extending burner tray (38) with a lower region (44) and upper region (46). The lower region (44) has a V-shaped cross-section, which shape improves the accuracy with which the rate of fuel consumption can be controlled through regulation of the level of fuel contained within this lower region. The upper region (46) includes upper side walls that extend upwardly and outwardly away from the lower region (44). This shape increases residency time of gaseous alcohol in the burner, allowing more time for a combustion reaction to run to completion.

IPC Classes  ?

• F23D 5/02 - Burners in which liquid fuel evaporates in the combustion space, with or without chemical conversion of evaporated fuel the liquid forming a pool, e.g. bowl-type evaporators, dish-type evaporators
• F23D 5/14 - Maintaining predetermined amount of fuel in evaporator
• F23D 5/18 - Preheating devices
