The outlet pipe of the steam generator is blown out

Water Handbook - Boiler System Failures | SUEZ

In some steam drum designs, water level is extremely critical because the baffling may isolate a generating section of the boiler when the steam drum water level falls below a certain point. Thin-lipped bursts also occur in superheater tubes when steam flow is insufficient, when deposits restrict flow, or when tubes are blocked by water due to a rapid firing rate during boiler start-up.

Once 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.

Steam systems should be piped to allow gravity drain-down when not in use, or should be blown out with compressed air at the end of each heating season. Source: Thanks to Duane Hagen of Merlo Steam for providing these photos and an explanation of what the problem is and the best way to fix it.

At ESI, we provide high-velocity steam blowing and steam blow out — we use low-pressure steam at near-sonic speeds. Before beginning steam blowing, it's critical to ensure your system is ready for it. Before steam blowing: Complete chemical cleaning of your system to ensure piping is ready for operation. Complete hydraulic testing of lines.

What is Boiler Blowdown ? - Surface Blowdown - Bottom …

Boiler blowdown is water intentionally wasted from a boiler to avoid concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within the boiler.
