Chapter 9 Boilers - NAVY B

2016-7-4 · An air cock is located in the uppermost steam space of a boiler, as shown in Figure 9-2. This design allows for air to enter and escape during filling and draining of the boiler. Before firing a cold boiler with no steam pressure, open the air cock to allow air to Figure 9-1—Boiler > Get A Quote >

Superheated Steam Water Tube Marine Boile

Marine boilers produce high pressure superheated steam to drive the turbines. The steam is generated by the water tubes which connect the water drum to the steam drum. Water and steam circulate through the vertical banks of tubes; the inner ones supplying the top drum and the outer ones dropping steam and water back to the water drum. The water tubes are heated by heavy fuel oil, which is > Get A Quote >

Steam Generator versus Steam Boil

2019-10-21 · A heat exchanger utilisation the waste heat in flue gas of the steam boiler or steam generator itself for increasing the boiler efficiency, is called an ECONOMISER. It can be used for preheating the feed water, but also for external purposes including preheating of make-up water, domestic water or central heating water. > Get A Quote >

Superheated steam drying: Design aspects

It is known by low pressure superheated steam drying (LPSSD). The design of this low pressure superheated steam dryer is illustrated in Fig. 6. A stainless steel drying chamber is insulated cautiously with rock wool, and a steam reservoir receives the steam from a boiler using a pressure control system. > Get A Quote >
