WebAn exhaust hood is a key component of the local exhaust ventilation system, which is mainly composed of an exhaust hood, duct, fan, and dust removal and purification equipment, as shown in Fig. 2.4. Figure 2.4. Components of an exhaust ventilation system. WebIn order to provide temperature control for the exhaust hood region of low pressure turbines, the exhaust hood sprays are activated in response to measured load and steam exhaust pressure. During start-up of the generator, the sprays always are turned on. During normal operation, the status of the sprays depends on the relative amounts of load ...
WebExhaust spray nozzles help to ensure safe steam turbine operation by protecting the exhaust casing and downstream components from heat damage. Steam turbines can be retrofitted with exhaust spray nozzles, especially when downstream instruments have been damaged by heat, steam flashing is occurring, or downstream components are becoming …
