systems, it was not available to maintain boiler feed water. To correct this problem, Worthington developed a small, independent, direct-acting, feed-water steam pump, first employed in September 1840, and patented July 24, 1844 (Fig. 1). The pump consisted of a steam engine connected by a common rod to a single-action, piston-driven water pump.Get Price
- Fill the boiler back up again and drain it one more time to get rid of the residual crud - Fill the boiler up again, to the normal water level and power it up and let it run until it starts to steam - Shut the power off and open the skim port - slowly manually add water to the boiler until water starts to come out of the skim port.Get Price
The water level is critical to ensure a flooded supply of water to downcomer tubes (Fig. 3). Because sufficient water level is critical, modern boilers are equipped with automatic low-water trip switches. Some older boilers may not have these relatively inexpensive devices. If a boiler does not have low-water trips, have these devices installed.Get Price
A lockshield valve is a type of valve that is fitted onto every radiator at the side where the water flows into the radiator from the boiler. The purpose of the lockshield valve is to help regulate the heat output of the radiator itself, and to allow for a heating engineer to balance the radiators so that all the radiators in the heating system output heat at around the same rate.Get Price

Apr 20, 2018 · For instance, capacitance level transmitters operate through a capacitor, hydrostatic level transmitters depend on the pressure of a fluid in a storage container for level measurement, while ultrasonic level transmitters convert the distance travelled by an ultrasonic wave to determine the level, and so on. However, all these level transmitters Get Price
Jan 17, 2006 · The lower was the boiler proper, and in normal operation was completely filled with water and fire-tubes. The other cylinder was a steam reservoir communicating with the boiler through several large vertical tubes. See The Thuile Locomotive for a similiar approach- a single boiler barrel is used but it is of figure-of-eight cross-section.Get Price

Atop the boiler is a working saddle tank. A balance pipe beneath it keeps water in the legs of the tank at the same level. Water can be added at any time through the filler cap. It is then pumped into the boiler via the hand pump mounted on the footplate on the right side of the cab. Reversing is via slip eccentrics, which drive the inside valves.Get Price

The tubes are tapered, simply to make their installation through the flue easier. Lancashire boilers often show corrugated flues, which absorb thermal expansion without straining the riveted seams. Another development was the "kidney flue" or Galloway boiler, where the two furnaces join together into a single flue, kidney-shaped in cross-section.Get Price
Jun 23, 2014 · If you connect both of those big boilers to a single boiler feed pump through a common condensate-return manifold, the water from the feed pump won't know where to go. It can't possibly enter both boilers equally because the boiler that's firing will be under a slightly greater pressure than the boiler that's not firing.Get Price
