Balance of Plant
Published in S. Can Gülen, Gas Turbine Combined Cycle Power Plants, 2019
Tanks and pressure vessels in the GTCC power plant are designed to have sufficient storage capacity to meet the requirements of the particular system application. They are fabricated from materials suited to the particular service. For demineralized water, raw/fire water and reclaimed water, bolted, field-erected storage tanks from carbon steel are specified. (Atmospheric tanks may be of bolted or welded construction.) Hydrous ammonia tanks are made from stainless steel. The fire–water storage tank should be designed in accordance with NFPA 22. A corrosion allowance should be incorporated into the design such that the tanks have a specified design life (e.g., 25 years or the warranty period). A typical minimum corrosion allowance is 1/16 in.
Occupational Health and Safety

All sites must have on-site firewater systems consisting of fire hydrants, supply mains, and a dedicated water supply capable of providing water at a flow and pressure adequate for the site’s automatic sprinkler and fire hose requirements. This system should be sized based on a credible fire scenario considering the occupancy, construction, and design of the sprinkler systems, as well as the anticipated hose flow required by firefighters. The firewater flow duration must be considered during the design process. The insurance industry and NFPA provide recommended firewater flow duration periods for administration, manufacturing, and storage occupancies. Typically, a flow duration of 90–120 min is used within the pharmaceutical industry.
Offshore Production
Published in Sukumar Laik, Offshore Petroleum Drilling and Production, 2018
The fire water system primarily consists of equipment to pump and distribute water for firefighting purposes. The water for this system is salt water taken from the sea. The pump takes suction from the sea and starts automatically upon the command of the FSD from the fire and gas panel. Firewater sprinkler/deluge loops located all over the open areas spray water over the equipment and vessels. Foam water hose reels are located at various locations throughout the platform so that all areas can be reached from at least two hoses. These hose reels deliver an aqueous film forming foam (AFFF or light water) with seawater to assist in extinguishing spill fires.
Stormwater harvested from a permeable pavement for use in the fire extinguishing system and non-potable uses of a building: a case study
Published in Urban Water Journal, 2022
Lucas Niehuns Antunes, Enedir Ghisi, João Carlos Souza
Figure 3 shows a schematic drawing of the permeable pavement and stormwater tank proposed for the building. The stormwater tank is divided into a lower and an upper tank; the upper tank stores the fire water and the stormwater for consumption (non-potable uses). The capacities of the lower and upper tanks are calculated according to Equations 1 and 2, presented in section 2.3.
