This document is prepared for the guidance of those charged with the design, construction, operation, and protection of fossil fueled (., coal, gas, or oil) or alternative fueled (., municipal solid waste, refuse derived fuel, biomass, rubber tires, and other bustibles) steam electric generating plants, bustion turbine and internal bustion engine electric generating plants, and high voltage direct current converter stations. This document provides fire prevention and fire protection remendations for the safety of construction and operating personnel, the physical integrity of plant ponents, and the continuity of plant operations. Nothing in this document is intended to restrict new technologies or alternative arrangements. 13 Application. This document is intended for use by persons knowledgeable in the application of fire protection for electric generating plants and high voltage direct current converter stations. 中國(guó)最龐大的資料庫下載 Copyright NFPA 中國(guó)最龐大的資料庫下載 The remendations contained in this document are intended for new installations, as the application to existing installations might not be practicable. However, the remendations contained in this document represent good industry practice and should be considered for existing installations. It should be recognized that rigid uniformity of generating station design and operating procedures does not exist and that each facility will have its own special conditions that impact on the nature of the installation. Many of the specific remendations herein might require modification after due consideration of all local factors involved. 14 Definitions. Alternative Fuels. Solid fuels such as municipal solid waste (MSW), refuse derived fuel (RDF), biomass, rubber tires, and other bustibles that are used instead of fossil fuels (gas, oil, or coal) in a boiler to produce steam for the generation of electrical energy. * Approved. Acceptable to the authority having jurisdiction. * Authority Having Jurisdiction. The anization, office, or individual responsible for approving equipment, materials, an installation, or a procedure. Barrier, Fire. A continuous membrane, either vertical or horizontal, such as a wall or floor assembly, that is designed and constructed with a specified fire resistance rating to limit the spread of fire and that will also restrict the movement of smoke. Such barriers can have protected openings. Biomass. A boiler fuel manufactured by means of a process that includes storing, shredding, classifying, and conveying of forest and agricultural byproducts (., woodchips, rice hulls, sugar cane). Combustible. Any material that does not ply with the definition of either nonbustible or limited bustible. Combustible Liquid. A liquid having a flash point at or above 100176。C). High Voltage Direct Current (HVDC) Converter Station. A facility that functions as an electrical rectifier (acdc) or an inventor (dcac) to control and transmit power in a high voltage work. There are two types of HVDC valves — the mercury arc valve and the presentday technology solid state thyristor valve. Both types of valves present a fire risk due to high voltage equipment that consists of oilfilled converter transformers, wall bushings, and capacitors in addition to various polymeric ponents. Interior Finish. The exposed interior surfaces of buildings including, but not limited to, fixed or movable walls and partitions, columns, and ceilings. Interior finish materials are grouped as Class A Interior Finish and Class B Interior Finish. Interior Finish, Clas
