          New IEEE Standard - Inactive-Withdrawn.<br />\n
          Withdrawn Standard. Withdrawn Date: Feb 06, 2006. Recommendations on hopper heating system performance and equipment requirements necessary to provide an economical and effective hopper heating system are presented. System characteristics are described, and heat transfer analysis is covered. Heating module design considerations are presented. Control, monitoring, and alarm systems are discussed. Insulation, installation, operation, and maintenance are addressed.<br />\n
          \t\t\t\t<br />\n
          Precipitators and baghouses are two systems designed to remove fly ash from boiler flue gas. Air pollution control regulations require that these precipitators and baghouses operate efficiently and reliably. Malfunctions or equipment failures could lead to boiler de-rating or complete shutdown, which increase the operation and maintenance expenses for the operating company. Problems related to fly ash collection in the hoppers, such as fly ash agglomeration and fly ash solidification, can lead to precipitator and baghouse shutdowns. The proper design and installation of hopper heating systems can significantly reduce the maintenance problems associated with fly ash plugging in hoppers.<br />\n
          This recommended practice is intended to define the system performance and equipment requirements to provide an economical and effective hopper heating system.

          This guide supplements other IEEE documents related to sound levels of power transformers. IEEE Std C57.12.00™ defines sound levels and IEEE Std C57.12.90™ describes factory test procedures. The purpose of this guide is to provide practical information about sound level and reduction techniques to assist users and manufacturers in the proper specification, design, manufacturing, testing, and application of liquid-immersed power transformers. This guide does not cover shunt reactors, dry-type, or distribution transformers. This is due to the many different issues related to sound level determination. It is up to the reader to determine applicability of the material in this guide to such equipment.
