| Resumen |
This standard, adopted as an American National Standard 28 July 1980, establishes minimum standards for the design, installation and operation of boiler-furnaces, their fuel burning, air supply and combustion products removal systems, which include induced-draught fans and related control equipment, to prevent furnace implosions. It offers 2 methods for minimising the risk of negative furnace draught in excess of furnace structural capability: design of the furnace and flue gas removal system so that the low gas flow maximum head capability of the induced-draught fan system with ambient air does not exceed the design pressure of furnace ducts and associated equipment; or provision of a furnace pressure control system, draught fan directional blocking, or run-backs. Contents: equipment requirements (furnace structural design; combustion products removal; furnace pressure control system); sequence of operations; functional and system requirements for interlock and alarm systems. |
