Maintenance and Overhaul of Steam Turbines WGP42 05

IMIA – WGP 42 (05) 5 1. Introduction Steam turbines are utilized in numerous industries to drive boiler fans, boiler feed and water pumps, process and chiller compressors, blast furnace blowers, paper mill line shafts, sugar mill grinders, and generators in a variety

Combined Cycle Power Plant - an overview | ScienceDirect Topics

Combined-cycle power plants ( Fig. 2.3) are compound gas turbine–steam turbine systems wherein the extreme hot exhaust from a gas turbine is employed to run a boiler, and the steam thus produced is fed into a steam turbine to generate power. These plants can deliver high power output at efficiencies as high as 50%–60% with low emissions and

DRAFT BOILER/FEEDWATER GUIDELINES - The National Board of Boiler and Pressure Vessel Inspectors

2.2.1 A steam boiler's hydrological cycle (steam generation) is similar to that of the earth's hydrological cycle. In a steam boiler system, there are three potentially destructive elements: oxygen, carbon dioxide, and solids. 2.2.2 As the boiler water is heated

Reducing Boiler Tube Failures | Inspectioneering

2012/7/1 · Therefore, Furnace Tube inspection and maintenance are essential activities for effective Boiler and heat recovery steam generator (HRSG) tube failures have been the primary availability problem for operators of conventional fossil-fueled and combined-cycle power plants for as long as reliable statistics have been kept for each generating source.

Guidance on Safe Operation of Steam Boilers

Guidance on the Safe Operation of Steam Boilers (Ref: BG01) is a guidance document intended to assist the designers, managers, operators, maintenance personnel and Competent Persons (CP) of new and existing steam boiler systems in addressing the

Water Handbook - Boiler System Failures | SUEZ

In some steam drum designs, water level is extremely critical because the baffling may isolate a generating section of the boiler when the steam drum water level falls below a certain point. Thin-lipped bursts also occur in superheater tubes when steam flow is insufficient, when deposits restrict flow, or when tubes are blocked by water due to a rapid firing rate during boiler start-up.
