On vessels with an exhaust economiser by pass valve, water temperature is a critical factor in preventing condensation and acid formation on the gas side. The minimum temperature of 140 degree C should be kept, when running with the exhaust gas bypassing the economiser. iii) Operation 1) Exhaust gas boiler …
Exhaust Gas Boilers And Economisers for Marine Machinery
It is a fluid-dynamic pump with no moving parts, excepting a valve to control inlet flow. A steam injector is a typical application of the principle used to deliver cold water to a boiler against its own pressure, using its own live or exhaust steam, replacing any mechanical pump.
Types of Boiler Mountings and Accessories Used In Boiler
Various valves provide access for maintenance and repair. The steam system collects and controls the steam produced in the boiler. Steam is directed through a piping system to the point of use. Throughout the system, steam pressure is regulated using valves …
Boilers295 Thermostatic traps operate on the principle of temperature change (steam is hotter than condensate). These traps contain valves that are opened or closed by thermal expansion and contraction. Bimetallic and bellows traps are examples of temperature-operated traps.
