TO THE OIL MEN OF THE DOMINION OF CANADA WHO MADE THE FIRST OFFER TO S0PPLY COLONIAL OIL FUEL TO THE BRITISH NAVY ^ £IQUID fuel is already substituted for coal in many steam- ships. When sufficient quantities can ,be obtained it has many obvious advantages over coal. At present it does not appear that adequate supplies are available. Competent authori- ties, here and abroad, are giving attention to this question, and to the development of supplies. If the want can be met at prices justifying the use of liquid fuel there will undoubtedly be a movement in that direction." Sir William H. White, Chief Constructor at the Admiralty, in 1899. Thomas Gibson Bowles, in a lively letter to Tke Times, mR.in 1900, hit the Admiralty hard for reducing " a fleet-in- being to a fleet in building," and denounced " the persis- tent refusal seriously to entertain or examine the matter of oil fuel." In July, 1904, Mr. Bowles asked whether the oil fuel experi- ments in warships had been satisfactory. Oil, he added, would carry a ship twice the distance coal would, but he doubted whether we could get a sufficient supply. -

INTRODUCTION If boilers water doesn’t receive proper treatment, the boiler will suffer from carryover, sludging, scale and corrosion, leading to weak and dangerous machinery. Long before the boiler fails, water-related problems will cause: ● Growing safety hazard ● Increased maintenance cost ● Additional fuel required - higher energy costs ● Lower boiler efficiency Correct boiler water treatment and follow-up of the water and steam condition, are of utmost importance for keeping the heat generation systems in good condition. By implementing a rigorous program of boiler water treatment, a vessel can greatly extend equipment life, reduce maintenance and enable thermal efficiency to be maintained at the designed level. The present report characterizes a ship heat generation system, its water treatment procedures and maintenance required. The main objective is to document the system and to establish optimal and standard operation processes. It is also an important piece of digital information, part of the ship information system, shareable and available for present and future crews, and a helpful tool to support company management. -
PREFERRED INSTRUMENTS a Division of Preferred Utilities Manufacturing Corporation SYSTEM OVERVIEW
• Control VFDs to Save Electricity • Communicate Important Plant Information • Improve Water Quality and Extend Boiler Life PREFERRED INSTRUMENTS A Division of Preferred Utilities Manufacturing Corporation SYSTEM OVERVIEW The Preferred Feedwater Center Control System Boiler feedwater control systems are often the most archaic controls in the steam plant. Poor boiler waterside control contributes to scaling, corrosion, and eventually hot spots and tube failures. The Preferred Feedwater Center is designed to improve the control of boiler feedwater by modulating up to four feedwater pumps and three transfer pumps. Deaerator temperature, level, and chemical pumps are controlled to improve boiler feedwater quality. Local feedwater monitoring is available by LCD keypad, or optional 10” color touch screen. Remote monitoring is available by RS232 Modbus, or Modbus over Ethernet if the touch screen is purchased. “Combustion Technology Since 1920” Preferred Instruments has been in business continuously since 1920. Located in Danbury Connecticut, our products are proudly made and supported in the United States of America. Our staff of service engineers, field service technicians, and service trained sales engineers are dedicated to making all of your projects a major success. FEEDWATER CENTER BENEFITS ENSURE CONSISTENT FEEDWATER TEMPERATURE AND PRESSURE MAINTAIN PROPER OXYGEN REMOVAL AT ALL FIRING RATES INTEGRATED MODEM FOR OFF-SITE MONITORING FIELD ADJUSTABLE PARAMETERS PLUG-IN OPTION BOARDS AVAILABLE FOR INSTANT FIELD UPGRADES Deaerator Control • Ensures a steady flow of properly treated boiler feedwater by precisely controlling deaerator temperature, pressure, and level. • Secure a continuous supply of make up water to the deaerator by controlling surge tank level. • Deaerator control allows the user to minimize deaerator venting and boiler blowdown and improve plant efficiency. -

Steam Turbine Performance Improvements Through R&M
Steam Turbine Performance Improvements Through R&M EEC WORKSHOP 16.09.2013-17.09.2013 PERFORMANCE ENHANCEMENT THROUGH TECHNOLOGY UPGRADATION On average Coal fired units have a life term of 25-30 years. Units which are older than 30 years are in the capacity range of 60 -110 MW and mostly are being phased out. A good number of 200 MW units would have completed 30 years & operate at efficiency levels less than 30%. Performance of these units can be improved by retrofitting improved technologies. General Comments Utilities must upgrade old plants to improve efficiencies to reduce (O&M) costs. Overall efficiency of a Thermal power plant strongly depends on the turbine’s performance. For some aging steam-turbine power plants, it may be more cost-effective to upgrade existing steam turbines rather than replace them. Turbine Cycle Improvements. Turbine Performance degrades with time. Machines with a higher VWO Capability are operated at nominal loads under degraded conditions. Deterioration in efficiency would be known only from specific assessment tests. Many a Capital Overhauls scheduled for Turbine refurbishment go unused due to non availability of spares for recovery of Heat rate loss. Scope of Improvements in Boiler Island Coal transport, conveying and grinding Boiler operation. Overhaul with new heat transfer surface Neural network (NN) control system Intelligent soot blower (ISB) system Air heaters Variable-frequency drive (VFD) motors on all major rotating equipment (usually improves efficiencies at lower than full load). Scope of Improvements Turbine Island Turbine Feed water heater Condenser Turbine drive/motor-driven feed pump. Water treatment system Boiler water treatment Cooling tower Boiler Furnace Modifications The furnace of a power plant boiler is the most significant component of a power plant affecting the thermal performance, apart from the steam turbine generator.
