Boiler Components The main components in a boiler system are the boiler feedwater heaters, deaerator, boiler, feed pump, economizer, boiler, superheater, attemperator, steam system, condenser and the condensate pump. In addition there are sets of controls to monitor water and steam flow, fuel flow, airflow and chemical treatment additions. Water sample points may exist at a number of places. Most typically the condensate, deaerator outlet, feedwater (often the economizer inlet), boiler, saturated steam and superheated steam will have sample points.

  • Steam Locomotive Firebox Explosion on the Gettysburg Railroad Near Gardners, Pennsylvania
    Steam Locomotive Firebox Explosion on the Gettysburg Railroad near Gardners, Pennsylvania Leadership ViTS Meeting 6 September 2005 Bryan O’Connor, Chief Office of Safety and Mission Assurance Accident Timeline Place: Gettysburg Railroad near Gardners, PA Accident Date: June 16, 1995 Gettysburg 1278 @ Gettysburg Oct 1988 The Accident: • Steam locomotive 1278 with six passenger cars had completed two excursions and was preparing for a third and final excursion for the day. • During slow climb up moderate grade, the boiler exploded, seriously burning the engineer and two firemen. • . (2) Events Associated with Proximate Cause • Operators began climb with too little water in boiler • Water-level continued to drop and by the time the locomotive had crested the grade the crownsheet of boiler was not covered by water and failed due to thermal overstress. • Failure of crownsheet opened boiler to the firebox (atmosphere) and the water in boiler flashed into high pressure steam. • Steam exploded through firebox door into the locomotive cab, seriously burning the engineer (third degree burns over 65% of body) and two firemen. (3) Events Associated with Proximate Cause Approx. 175 psi This figure is exaggerated to show low water conditions, in locomotive 1278 the lowest gage cock was 3.25 inches above the highest point of the crownsheet and the water glass was 3.125 inches above the highest point of the crownsheet (4) Contributing Factors • Prior to operation the feed pump gauge had been removed. • Preparing to ascend grade first fireman shut off the feed pump to the boiler because a leaking check valve between the feed-pump and the boiler could potentially cause slippage on driving wheels.

  • Operating and Maintenance Manual for Boiler Water Or High Temperature Hot Water (Hthw) Powered Water Heater
    OPERATING AND MAINTENANCE MANUAL FOR BOILER WATER OR HIGH TEMPERATURE HOT WATER (HTHW) POWERED WATER HEATER ELECTRIC HEATER COMPANY BASE MODEL “ BW and BWH ” HUBBELL ELECTRIC HEATER COMPANY P.O. BOX 288 STRATFORD, CT 06615 PHONE: (203) 378-2659 FAX: (203) 378-3593 INTERNET: http://www.hubbellheaters.com/ -- IMPORTANT -- Always reference the full model number and serial number when calling the factory. WARNING / CAUTION 1. Tank is to be completely filled with water and all air is to be vented before energizing. 2. Due to the rigors of transportation, all connections should be checked for tightness before heater is placed in operation. 3. Safety relief valve must be installed in tapping provided. 4. KEEP AWAY FROM LIVE ELECTRICAL CIRCUITS. Do not perform any maintenance, make any adjustments, or replace any components inside the control panel with the high voltage power supply turned on. Under certain circumstances, dangerous potentials may exist even when the power supply is off. To avoid casualties, always turn the power supply safety switch to off, turn the charge or ground the circuit before performing any maintenance or adjustment procedure. 5. Generalized instructions and procedures cannot anticipate all situations. For this reason, only qualified installers should perform the installation. A qualified installer is a person who has licensed training and a working knowledge of the applicable codes regulation, tools, equipment, and methods necessary for safe installation of a steam fired water heater. If questions regarding installation arise, check with your local plumbing and electrical inspectors for proper procedures and codes. If you cannot obtain the required information, contact the company.

  • Steam Drum Water Level Measurement
    FOSSIL POWER SYSTEMS INC. STEAM DRUM WATER LEVEL MEASUREMENT A. Introduction. Boiler steam drum water level is one of the most important power plant parameters to both measure and control. Control of the proper water level in the boiler is critical for safe operation of the boiler. If the level is too low, boiler tubes will be damaged by overheating. If the level is too high, steam separators will not function properly, temperature control will be difficult, and the superheater tubes and turbine could be damaged by moisture or water treatment chemical carryover. In addition, poor level control will also adversely affect the drum pressure control. The sliding operating pressure of modern 3 drum Heat Recovery Steam Generators, along with frequent startup and shut down, has added to the challenge of selecting the proper mix of instruments and maintaining correct water levels under all conditions. Although instruments for drum water level measurement have been around for well over a hundred years, it is important to understand the operating principles, installation requirements, strengths and weaknesses of each technology. To ignore these considerations can lead to misapplication, increased maintenance, poor instrument performance, and unsafe operation. The ASME Boiler and Pressure Vessel Code Section I establishes the requirements for steam drum water level measurement in fired steam drums. The primary focus of these requirements is safe boiler operation. Maintenance, performance, and other specific application issues are not addressed. There are a dozen or more level technologies that could be considered for this application. The purpose of this paper is to review 5 of the proven technologies currently available for high pressure steam drum water level measurement.

  • Steam Locomotive Firebox Explosion on the Gettysburg Railroad Near Gardners, Pennsylvania June 16, 1995
    PB96-917008 NTSB/SIR-96/05 NATIONAL TRANSPORTATION SAFETY BOARD WASHINGTON, DC 20594 SPECIAL INVESTIGATION REPORT STEAM LOCOMOTIVE FIREBOX EXPLOSION ON THE GETTYSBURG RAILROAD NEAR GARDNERS, PENNSYLVANIA JUNE 16, 1995 . Illlr 6768 Abstract: On June 16, 1995, the firebox crownsheet of Gettysburg Passenger Services, Inc., steam locomotive 1278 failed while the locomotive was pulling a six-car excursion train about 15 mph near Gardners, Pennsylvania. The failure resulted in an instantaneous release (explosion) of steam through the firebox door and into the locomotive cab, seriously burning the engineer and the two firemen. This accident illustrates the hazards that are always present in the operation of steam locomotives. The Safety Board is concerned that these hazards may be becoming more significant because Federal regulatory controls are outdated and because expertise in operating and maintaining steam locomotives is diminishing steadily. As a result of its investigation, the National Transportation Safety Board issued safety recommendations to the Federal Railroad Administration, the National Board of Boiler and Pressure Vessel Inspectors, and the Tourist Railway Association, Inc. The National Transportation Safety Board is an independent Federal agency dedicated to promoting aviation, railroad, highway, marine, pipeline, and hazardous materials safety. Established in 1967, the agency is mandated by Congress through the Independent Safety Board Act of 1974 to investigate transportation accidents, determine the probable causes of the accidents, issue safety recommendations, study transportation safety issues, and evaluate the safety effectiveness of government agencies involved in transportation. The Safety Board makes public its actions and decisions through accident reports, safety studies, special investigation reports, safety recommendations, and statistical reviews.
