Cotton, Arthur Freedman Associates, Inc. and Orin Hollander, Holland Technologies, Inc. This is part two of a three-part series on boilers. In part one, the authors discussed boiler design and classification. Part two will discuss boiler components, and part three will describe the various chemistries used in boiler water treatment. 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. -

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. -

Hampshire Area Garden Railway Group (incorporating the Hampshire area of the Association of 16mm Narrow Gauge Modellers, and the Southdown Railway Co.) Associate members of Fareham & District Model Railway Club May 2012 Welcome to this months newsletter. The rain seems to have been endless since Easter, I do hope some of you have managed some running! Lets begin with someone who’s been playing on bigger trains. Norman Tyler has been to Argentina, to the End of the World Railway. The Southern Fuegian Railway or the Train of the End of the World is a 500 mm (19 3⁄4 in) (nar- row-gauge) steam railway in Tierra del Fuego Province, Argentina. It was originally built as a freight line to serve the prison of Ushuaia, specific- ally to transport timber. It now operates as a heritage railway into the Tierra del Fuego National Park and is considered the southernmost functioning railway in the world. The pictures show Norman on board a Garratt from South Africa to a design from Beyers at Gorton Manchester and another of the Garratt running round at the distant terminal. Apparently they run champagne and dinner trains. No wonder Norman is smiling. No trouble with the weather there then! Moving on to some model news, an interesting (I thought) idea with my Leek and Manifold locomotive was to replicate the look of the original headlamp. According to the books, the lamp was supplied painted in livery colours but that paint did not remain intact for very long, peeling to reveal the copper underneath. To preserve the appearance of their engines, the drivers polished the copper regularly. -
