FOREWORD

The major perils in operating automatically fired boilers are loss of water (low water), furnace explosion, overpressure, and overtemperature. Principal causes of accidents to automatically fired boilers are lack of proper controls and safety devices, lack of adequate maintenance, improperly trained operators, failure to test controls and safety devices, and complacency on the part of the operator due to long periods of trouble-free operation. It is believed that improved instrumenta- tion, controls and safety devices, proper operating procedures, and a clearer understanding of installation requirements by the manufacturers, installers, and operators can greatly reduce the chances of personal injury, damage to property, and loss of equipment from accidents.

It should be pointed out that any governmental jurisdiction has authority over any particular installation. Inquiries dealing with problems of a local character should be directed to the proper authorities of such jurisdictions.

Safety codes and standards are intended to enhance public health and safety. Revisions result from the committee’s consideration of factors such as technological advances, new data, and changing environmental and industry needs. Revisions do not imply that previous editions were inadequate.

   CORRESPONDENCE WITH THE CSDAFB COMMITTEE

   
   

   General. ASME Standards are developed and maintained with the intent to represent the consensus of concerned interests. As such, users of this Standard may interact with the Committee by requesting interpretations, proposing revisions or a Case, and attending Committee meetings. Correspondence should be addressed to:

   Secretary, CSDAFB Standards Committee

   The American Society of Mechanical Engineers Two Park Avenue

   New York, NY 10016-5990

   https://go.asme.org/Inquiry

   
   

   Proposing Revisions. Revisions are made periodically to the Standard to incorporate changes that appear necessary or desirable, as demonstrated by the experience gained from the application of the Standard. Approved revisions will be published periodically.

   The Committee welcomes proposals for revisions to this Standard. Such proposals should be as specific as possible, citing the paragraph number(s), the proposed wording, and a detailed description of the reasons for the proposal, including any pertinent documentation.

   Proposing a Case. Cases may be issued for the purpose of providing alternative rules when justified, to permit early implementation of an approved revision when the need is urgent, or to provide rules not covered by existing provisions. Cases are effective immediately upon ASME approval and shall be posted on the ASME Committee Web page.

   Requests for Cases shall provide a Statement of Need and Background Information. The request should identify the Standard and the paragraph, figure, or table number(s), and be written as a Question and Reply in the same format as existing Cases. Requests for Cases should also indicate the applicable edition(s) of the Standard to which the proposed Case applies.

   Interpretations. Upon request, the CSDAFB Standards Committee will render an interpretation of any requirement of the Standard. Interpretations can only be rendered in response to a written request sent to the Secretary of the CSDAFB Standards Committee at go.asme.org/Inquiry.

   The request for an interpretation should be clear and unambiguous. It is further recommended that the inquirer submit his/her request in the following format:

   
   

   Subject: Cite the applicable paragraph number(s) and the topic of the inquiry.

   Edition: Cite the applicable edition of the Standard for which the interpretation is being requested.

   Question: Phrase the question as a request for an interpretation of a specific requirement suitable for general understanding and use, not as a request for an approval of a proprietary design or situation. The inquirer may also include any plans or drawings that are necessary to explain the question; however, they should not contain proprietary names or information.

   
   

   Requests that are not in this format may be rewritten in the appropriate format by the Committee prior to being answered, which may inadvertently change the intent of the original request.

   ASME procedures provide for reconsideration of any interpretation when or if additional information that might affect an interpretation is available. Further, persons aggrieved by an interpretation may appeal to the cognizant ASME Committee or Subcommittee. ASME does not “approve,” “certify,” “rate,” or “endorse” any item, construction, proprietary device, or activity. Attending Committee Meetings. The CSDAFB Standards Committee regularly holds meetings and/or telephone conferences that are open to the public. Persons wishing to attend any meeting and/or telephone conference should contact the Secretary of the CSDAFB Standards Committee.

   
   

   IN MEMORIAM

   Jules “Red” A. Wagner

   
   

   The CSDAFB Standards Committee wishes to acknowledge one of the founding members who passed away during the production of this Edition. He was a major contributor to CSD-1, a member of ASME since 1955, and an active member of the Standards Committee for over 35 years. Jules “Red” A. Wagner passed away on August 16, 2013.

   “Red” was a major contributor to the development of this document. In addition, he supported the CSDAFB Standards Committee as a tireless contributor and founding member. “Red” was well liked; someone you could rely on and trust. He lived by the United States Merchant Marine Academy motto: Acta non Verba (“Deeds not Words”), the officer’s creed and the honor code.

   His presence and friendship, as well as his continual guidance to the Committee in the mainte- nance of the CSD-1 standard and straightforward attitude, will be truly missed.
