CEA BG06 - De-Aerators And Hot Wells
This comprehensive guide deals with all aspects of feedwater provision for industrial steam boilers (shell boilers) and why it is necessary to carefully manage and control the water that is supplied to the boiler. We trust that by studying the contents and following this advice your boiler plant will operate safely and more efficiently, and provide you with a trouble-free system. INTRODUCTION Hot wells and De-aerators – Guidance for Industrial installations (Ref: BG06) is a guidance document intended to provide advice to designers, specifiers, manufacturers, installers and those responsible for the management and operation of steam plant as well as Competent Persons (CP). It is applicable to both new and existing installations of hot wells and de-aerators and addresses the following issues: The safe and correct provision of feed water for steam boilers; The safe use and operation of hot wells and de-aerators; Proper maintenance and inspection of hot wells and de-aerators ABOUT THIS GUIDE This comprehensive guide deals with all aspects of feedwater provision for industrial steam boilers (shell boilers) and why it is necessary to carefully manage and control the water that is supplied to the boiler. We trust that by studying the contents and following this advice your boiler plant will operate safely and more efficiently, and provide you with a trouble-free system. If in any doubt contact the supplier, the system designer or your boiler water treatment specialist for advice. It is aimed at the Owner, Operator, Engineer and Manager of the boiler plant to help them understand all aspects that affect the boilers and their water supply arrangements, both from a practical operational performance view and for the legal requirements. It covers who is responsible for the safe and efficient operation of steam boiler plant, and who is responsible for managing the safe operation of this type of equipment. Ultimately the responsibility lies with the most senior person on site. With other HSE guidance being withdrawn, and having taken all factors into consideration, The Combustion Engineering Association (CEA) agreed to write this guide with the help of its members. Within this Guide there are a significant number of legal requirements, regulations and standards highlighted; these regulations and standards are periodically reviewed and they can and do change, but they are as accurate as possible at the time of publication. CEA cannot accept any liability for the information provided herein; however, be assured that we have consulted widely with our member companies during the compilation of this guide. SCOPE This guidance applies to feed water arrangements using hot wells and de-aerators of various designs for supplying feed water to steam boilers in commercial and industrial installations. The primary purpose of a hot well or de-aerator is to manage and reduce the amount of dissolved gases in boiler feed water.
