      <title>EXPERIENCE WITH INSTALLATION OF STEAM PROPULSION PLANTS</title>
      <link>https://trid.trb.org/View/153391</link>
      <description><![CDATA[Experience of past and present operating steam turbine plants can provide valuable guidelines for future designs. With this paper it is the author's intention to add a shipbuilder's experience with installation of steam plants. The experience gained on the above subject is divided into design, commissioning, tests and initial costs.  The design section deals with the boiler configuration of the 1 1/2-boiler system and gives some experience for drain problems which must be considered when deciding the layout. As the main boiler is the heart of the steam propulsion plant most consideration is paid to criteria to be considered for water level control and burner arrangement. Necessary space for the installation as well as the advantages of using a scale 1:15 engine room model are included.  From the commissioning of plants the yard has learned that cleanliness of systems and careful planning of activities are very important.  A very careful commissioning of boilers is absolutely necessary to minimize the risk of furnace explosion.  Tests and trials have to be continued until everything is functioning as intended and a careful and good adjustment of the burners and the combustion control is of vital importance, in fact this period should be given the time necessary to reach a satisfactory result.  The initial costs are mentioned briefly, which are in themselves only one of more parameters to be considered when diciding a ship's type of propulsion plant.]]></description>

      <title>IMPROVED MARINE BOILED RELIABILITY--PHASE II</title>
      <link>https://trid.trb.org/View/143023</link>
      <description><![CDATA[Presented in this paper are the results of a Maritime Administration-funded shipboard and laboratory test program the second phase of a project to identify and investigate design and operational parameters which have a significant impact on the performance, availability, and reliability of oil-fired marine boilers.  The research test results and engineering analyses are discussed as they pertain to the following task areas which affect marine boiler reliability: superheater corrosion rates; economizer corrosion rates; steam-side distribution in superheaters; stack gas analysis; thermocouple modernization and shipboard use; and boiler water and feedwater quality maintenance.  Recommendations based upon both phases of the program are presented which will enable the boiler purchaser or designer to specify certain materials, design features, and operating guidelines which should assist in establishing a predetermined level of boiler reliability for specific anticipated operating modes and environment.]]></description>

      <title>EXAMINATION BY NON-DESTRUCTIVE TESTING METHODS OF WATER-TUBE BOILERS IN H.M. SHIPS</title>
      <link>https://trid.trb.org/View/18371</link>
      <description><![CDATA[Nondestructive testing techniques have been developed by the Ship Department of the Ministry of Defence for the examination of the pressure parts of water-tube boilers in Her Majesty's ships.  The paper discuses the suitability of the equipment and methods employed for the pattern of deterioration of boiler parts normally encountered and observed over many years.  The use of ultrasonic viewing, measuring, and photographic devices to permit realistic assessment of present condition, and how these methods lead to accurate prediction of remaining service life or repair requirements are considered.  Details are given regarding the application of these methods in the fleet, including the training of operators and documentation; also of on-board trials, which resulted in the establishment of a central boiler inspection unit.]]></description>

      <title>SELF-REGULATING STEAM GENERATOR: A PROGRESS REPORT</title>
      <link>https://trid.trb.org/View/1223</link>
      <description><![CDATA[The self-regulating steam generator is a device designed to help achieve single-lever controllability of a marine steam power plant.  This paper presents an abbreviated history of the SRSG development, defines the scope of control provided by the new system and describes at some length the purpose, procedures and results of actual boiler testing during the period from initial boiler light-off to completion of the preliminary test operation.]]></description>

      <title>A MATHEMATICAL MODEL FOR DYNAMIC ANALYSIS OF A BOILER</title>
      <link>https://trid.trb.org/View/11145</link>
      <description><![CDATA[The paper outlines a mathematical model of an oil fired boiler for a steam production of about 95 t/h which comprehends the whole boiler system from the inlet of fuel oil, air and water to the outlet of superheated steam. Special attention is paid to the calculation of water circulation and two-phase flow of water and steam in the risers.  This makes it possible to calculate variations of the drum water level due to swell and shrink.  The differential equation system, which is of the 12th order, is solved by a digital computer, Univac 1108, the computation time being about 1/10th of the real time for the process.  The model is primarily adjusted to a Foster Wheeler boiler type ESD 11.  To verify the results obtained from the calculation comprehensive tests have been carried out by Det Norske Veritas on the same type of boiler on board a ship, the T/T OCTAVIAN, Hilmar Reksten Shipping Co.  The results obtained from the calculation and from the tests are given in the paper.]]></description>

      <title>A MATHEMATICAL MODEL OF A MAIN BOILER FOR 60,000 KW CONTAINER SHIP</title>
      <link>https://trid.trb.org/View/11146</link>
      <description><![CDATA[The paper describes how mathematical models of dynamic characteristics were formulated for one of two main boilers installed in SS "KAMAKURA MARU" an 80,000 hp high speed container ship, analysed by computer simulation technique and checked against the results of actual measurements made in October 1971 before the ship was handed over to the owner in November.  The discrete-space continuous-time finite difference method was used and the water circulation loops, i.e. furnace waterwalls, downcomers etc. were divided into eleven space lumps and, similarly, the superheater and control desuperheater were divided into eight and two space lumps respectively.  The mathematical models feature the use of non-linear equations to analyze the boiler dynamic responses to drastic load change peculiar to the ship's boilers, and were found highly practical for use in the analysis of dynamics of large capacity boilers.]]></description>

      <title>CONSIDERATION AND EXPERIMENTAL STUDIES ON SUPERCHARGED ONCE-THROUGH BOILERS</title>
      <link>https://trid.trb.org/View/5391</link>
      <description><![CDATA[Experimental studies and consideration on the two supercharged test boilers developed at the Ship Research Institute are described in this paper. With these boilers, many new concepts such as adoption of the combined supercharged and once-through boiler type, the adoption of a supercharger set which is originally designed for Diesel engines, the adoption of a swirl-flow heating surface, and the use of a booster fan system for starting, etc., are successfully tested. By these experimental results, it becomes clear that this study is very helpful in design of modern, compact, simple, efficient, inexpensive, easily controlled and reliable supercharged boilers.]]></description>

      <title>THERMAL PROBLEMS IN QUICK START AND RAPID LOAD INCREASE OF MARINE STEAM TURBINES AND BOILERS</title>
      <link>https://trid.trb.org/View/5390</link>
      <description><![CDATA[Some series of tests of quick start and rapid load increase were carried out on naval steam turbines and boilers in their sea trials to improve their operational flexibilities. In the tests, the turbines were accelerated from 12 Knots speed to the maximum speed within 25 to 14 minutes, while the boilers were started up to their working pressure in 100 to 50 minutes. Thermal stresses at the horizontal flanges and the flange bolts of the turbine casings, relative expansion between the rotors and the casings were mainly measured on the turbines, and the superheater tube wall temperature, distortion of the water drum and the stress caused by the distortion on the boilers. In this paper, the results of the tests and the consideration of the authors derived from them are mentioned, including the method to minimize the thermal stress in turbine casings and the similarity of the thermal stress when the scale is changed.]]></description>
