The starting point for the distribution system is the boiler house, where it is often convenient for the boiler steam lines to converge at a steam manifold usually referred to as the main distribution header. The size of the header will depend upon the number and size of boilers and the design of the distribution system.

So e.g. if your pressure vessel is fed by a pump which has say a normal operating pressure of 5 bar, but on no flow the inlet pressure to the pump increases and then the no flow differential pressure increases and so the max pressure from the pump is 10 bar. So if you had set the design pressure of the vessel at say 7 bar, then you now need

Photo 15: Cut the curved braces. Cut two 4-ft. lengths of 2×10 and tack them between the 2×4 rafter and ceiling tie parts to lay out the curved decorative braces (our positions vary because of the differing roof slopes). Mark the lengths at the 2x4s. Bend and clamp a thin board and trace arcs about 7-1/2 in. apart on both sides.

Bathroom exhaust fans, or vent fans, are required by the NEC (National Electrical Code) and local building codes for any bathroom that doesn't have a window that can be opened to provide ventilation, and in some jurisdictions, they are required even if windows are present.A vent fan does two important things: It removes hot, moist air and it can remove odors.

Steam heating boiler operating temperatures: You won't normally see a temperature gauge on a steam boiler: the boiler has to "boil" water to make steam so it's a safe bet that water in the boiler, when it's making steam, will be around the boiling point.

A back pressure steam cycle works as follows. The boiler produces 8 kg/s of steam at 40 bar and 500oC. This is expanded to 2 bar with an isentropic efficiency of 0.88. The pump is supplied with feed water at 0.5 bar and 30oC and delivers it to the boiler at 31oC and 40 bar. Calculate the net power output of the cycle. (Answer 5.24 MW)

Why Hydrotest Pressure Is 1.5 Times Design Pressure - posted in Refining, Hydrocarbons, Oil, and Gas: Dear all, Why ASME B31.3 specify the hydrotest pressure for process lines are 1.5 times of design pressure. Why not other fractions i.e., 1.6 or 1.4 times of design pressure. Is there any reason for specifing 1.5 times of Design pressure.

Hi, Had similar problem with mothers Ideal Logic about 6 years old, as a retired Gas safe engineer I was able to monitor the loss of pressure which dropped 0.5 of a bar every 7 days, there was no sign of leakage on heating system & no water from expansion pipe, my mother has a service contract but because there was no water visual at base of combustion chamber the engineer was not convinced
