16、ventive Maintenance Schedule 39E References 43Index 44ivFOREWORDThe major perils in operating automatically fired boilers are loss of water (low water), furnaceexplosion, overpressure, and overtemperature. Principal causes of accidents to automatically firedboilers are lack of proper controls and sa
17、fety devices, lack of adequate maintenance, improperlytrained operators, failure to test controls and safety devices, and complacency on the part of theoperator due to long periods of trouble-free operation. It is believed that improved instrumenta-tion, controls and safety devices, proper operating
18、 procedures, and a clearer understanding ofinstallation requirements by the manufacturers, installers, and operators can greatly reduce thechances of personal injury, damage to property, and loss of equipment from accidents.It should be pointed out that any governmental jurisdiction has authority ov
19、er any particularinstallation. Inquiries dealing with problems of a local character should be directed to the properauthorities of such jurisdictions.Safety codes and standards are intended to enhance public health and safety. Revisions resultfrom the committees consideration of factors such as tech
20、nological advances, new data, andchanging environmental and industry needs. Revisions do not imply that previous editions wereinadequate.The first edition of this Standard, which was approved by The American Society of MechanicalEngineers Committee on Controls and Safety Devices for Automatically Fi

ASME Codes and Standards are developed and maintained with the intent to representthe consensus of concerned intere
35、sts. As such, users of this Standard may interact with theCommittee by requesting interpretations, proposing revisions, and attending Committee meet-ings. Correspondence should be addressed to:Secretary, CSDAFB Standards CommitteeThe American Society of Mechanical EngineersThree Park AvenueNew York,
36、 NY 10016-5990Proposing Revisions. Revisions are made periodically to the Standard to incorporate changesthat appear necessary or desirable, as demonstrated by the experience gained from the applicationof the Standard. Approved revisions will be published periodically.The committee welcomes proposal
37、s for revisions to this Standard. Such proposals should beas specific as possible, citing the paragraph number(s), the proposed wording, and a detaileddescription of the reasons for the proposal including any pertinent documentation.Interpretations. Upon request, the CSDAFB Committee will render an
38、interpretation of anyrequirement of the Standard.
