This standard sets out requirements for the design, construction, and control functions of automatic burners which are-(a) for use on equipment that is generally industrial or commercial in nature, i.e. boilers, ovens, furnaces, or the like; (b) for use with gas or liquid fuels, being either single fuel burners, or burners in which differing fuels may be burned either simultaneously or alternatively; (c) designed so that some or all of the air for combustion is provided by mechanical means, i.e. natural draught burners such as atmospheric gas burners or vaporizing oil burners are excluded; and (d) for use either as single burners or as part of a multiple burner installation.NOTES:1. Application standards such as AS 1375 set particular conditions for burners used in multiple sets.2. Although this standard is written on the basis of conventional oil and gas fuels, it is recognized that applications exist in which less common combustible materials need to be used as a fuel. This standard is intended to cover these applications, but it is necessary to pay particular attention to the individual properties of any such fuel, specially its effect on materials or personnel.
