This Part of BS 5885 specifies minimum requirements for automatic gas burners employing forced or mechanically induced draught and having a heat input rating of 60 kW and above. such burners may be of packaged or non-packaged types, and may be designed for use with 1st, 2nd or 3rd family gases. BS 5885 applies to burners intended for use in industrial processes. rt does not cover burners intended for use in heating appliances, e.g. boilers, which are covered by BS EN 616, AutomatiC forced draught burners for gaseous fuels. It covers single burners and dual fuel burners when operating only on gas. It does not cover multi-burners. Guidance on dual fuel burners is given in Appendix A. This Part of BS 5885 specifies requirements primarily for the safety aspects of automatic control and operation. It does not constitute a complete specification for automatic burners and their ancillary equipment. NOTE 1 The use of gases which are dirty, wet, of variable composition or high dewpoint may cause difficulties which are not covered in detail by this Part of BS 5885. In such cases, suppliers and users of equipment will need to take additional measures to comply with the requirements of this standard. NOTE 2 Burners complying with this Part of BS 5885 meet the statutory requirements for the protection against flow of air into piped gas supplies in the following circumstances: where the maximum combustion air pressure is not greater than 50 mbar1); where the maximum combustion air pressure is not greater than 15 mbar, and where the start-gas and main gas supplies are each under the control of at least one class 1 safety shut-off valve of size not greater than 50 mm; where the start-gas and main gas supplies are each under the control of at least one safety shut-off valve with a proved capability of withstanding a reverse flow pressure differential of at least twice the maximum combustion air pressure. In other circumstances burners complying with this Part of BS 5885 may require additional protection, e.g. non-return valves, and in such cases reference should be made to the fuel supplier. NOTE 3 The titles of the publications referred to in this standard are listed on pages 23, 24 and on the inside back cover.
