233.60-1 Feedwater enters the boiler near the bottom of the tube bundle. The feedwater as it leaves the last feed-heater, is still much colder ( 175 C) than the water in the steam generator, and to reduce the possibility of thermal shock to a minimum, the water must

Manual blowdown can be accomplished through taping at the bottom of the boiler where settled solids are removed. With manual blowdown water level control devices and cutoff devices are kept clean of any solids interfering with their operation. All steam boilers requires an arrangement for manual blowdown even if they are supplied with automatic

Steam accumulators can also be used with electrode or immersion heater boilers so that steam can be generated off peak, stored, and used during peak times. The possibilities are endless. In summary, the steam accumulator is an efficient tool, as it may well provide the most cost effective way of supplying steam to a batch process.

2016/2/24 · Nowadays, most boilermakers install a connection for TDS blowdown, and it is generally possible to obtain a representative sample from this location. If water is simply drawn from the boiler, a proportion will violently flash to steam as its pressure is reduced.

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.
