How to Destroy a Boiler -- Part 1

Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.

Dan Gelbart's Advanced Uniflow Steam Engine

Feed water for the boiler is pre-heated in the condenser reservoir by exhaust steam from the engine. A water pump powered by the steam engine supplies feed water to the boiler. An electromagnetic valve cuts off the water supply when boiler is full. A steam pressure sensor controls gas flow to burner; the flame is reduced to a pilot when boiler ...

Reasons why the condensate- or boiler-feed pump is ...

Jun 25 2014 · The boiler's water line is priming or surging. Dirt is usually the culprit here. When you see droplets of water in the part of the gauge glass above the water line it's time to clean the boiler. If the boiler is priming and surging it can turn the pump controller on and off. That will make the boiler-feed pump add water when it shouldn't.

Pumps Selection & Sizing - Industrial steam

The ASME code requires that the boiler feed pump be able to put water in the boiler at the evaporation rate at a pressure which is 3% greater than the highest setting of the safety valves. If the boiler in this example is designed for 150 psig operating pressure the safety valves could be set at 175 psig.

Marine Steam Boilers Steam and Water System

The feedwater is pre-heated in order to increase the efficiency of the plant. The circulating water to the exhaust gas boiler heats the feed water and the three-way valve on the inlet to the heat-exchanger controls the temperature. The economizer inlet temperature must never fall below 135°C to avoid corrosion on the economizer tubes.
