Boiler Design Considerations for Cycling Operations

The most rapid startup designed cycling boilers utilize all drainable superheater surface. The drainable circuitry allows for draining of condensed water within the elements after shutdown. Some cycling boilers do have non-drainable superheater elements, but much care must be taken during unit starts that all

b. Water in the steam line actually is good because it de-superheats any superheated steam produced by the boiler. c. Water in your steam line is just an old steamers fable. d. If steam lines are not heated up fully some of the steam will be used to heat the lines which forms condensate, which has to be removed by traps and drains.

In the case of a traditional firetube boiler, it can take over an hour from your initial startup until your steam is ready for your production line. In order to combat this, employees are brought into the plant early for startup, or the boiler is kept at a warm tandby,?effectively leaving the boiler in a constant idle state.

Steam explosion - Wikipedia

If a steam explosion occurs in a confined tank of water due to rapid heating of the water, the pressure wave and rapidly expanding steam can cause severe water hammer. This was the mechanism that, in Idaho, USA, in 1961, caused the SL-1 nuclear reactor vessel to jump over 9 feet (2.7 m) in the air when it was destroyed by a criticality accident .
