Steam generator (auxiliary boiler) - Wikipedia. A steam generator on a ship is an auxiliary boiler which draws high-pressure superheated steam from the vessel's propulsion system to generate low pressure saturated steam.This secondary steam is then used to power auxiliary shipboard engines driving winches or pumps, or to meet any steam requirement that does not require superheating, such as
A recuperator captures waste heat in the turbine exhaust system to preheat the compressor discharge air before it enters the combustion chamber. A HRSG generates steam by capturing heat from the turbine exhaust. These boilers are also known as heat recovery steam generators.
Boilers 291 Coagulation—a method for concentrating and removing suspended solids in boiler feedwater by adding chemicals to the water, which causes the impurities to cling together, p. 301. Condensate—condensed steam, which often is recycled back to the boiler, p. 294. Damper—a movable plate that regulates the flow of air or flue gases in boilers,
(note: pump in front of flywheel to recycle condensed exhaust steam) Typically, the exhaust steam is condensed and pumped back into the boiler to increase efficiency. A small pump on the engine pumps the condensed water into the boiler for a closed loop system. Do-It-Yourself Plans for . this 2 Cylinder Engine are Available below.
A steam boiler system includes a steam air preheater disposed in inlet ducting for preheating intake air. A boiler feed pump provides high-pressure water to a boiler which in turn produces steam to drive a main turbine. Exhaust flow from the turbine is routed directly to a main condenser, with the exception of a small extraction flow which is used to drive a boiler feed pump turbine.
