Get priceThis steam trap is therefore acting mostly as a "steam cooler" wasting steam from the Steam Main. Note the nice insulation job however; this is probably keeping the problem from being much worse. Condensate should always be drained from the BOTTOM of the steam line in low sections of pipe and at changes in direction, such as a 90 Degree turn.

Get priceOnce the water/steam enters the drum from the economizer outlet header via the economizer connecting pipe, it is forced by gravity down pipes called downcomers. Downcomers are large diameter pipes (25 in. IPS) that take the water/steam coming from the steam drum down to the lower water wall headers of the convection pass and furnace walls.

Get priceFor preliminary checking, gradually raise steam pressure to 4 MPa at either boiler drum (drum-type steam generator) outlet or water separator (once-through steam generator) outlet; ii. Maintain the water level in the boiler drum or separator near to the lowest visible limit in the gauge glass prior to opening the temporary blow-out valve.
Get priceat the design stage. Figure 3.2 Steam Distribution System As steam condenses in a process, flow is induced in the supply pipe. Condensate has a very small volume compared to the steam, and this causes a pressure drop, which causes the steam to flow through the pipes. The steam generated in the boiler must be conveyed through
