Boiler Preparation, Start-Up and Shutdown
Small boilers often have completely automatic ignition systems. Some older, or specialized boilers, may have completely manual systems. Most boilers have a combined system, where some steps, such as 1 and 2 above, are done automatically, and the remaining steps require the operator to perform specific tasks within a set time period.

Tower Types and Two Pass Boilers - Bright Hub Engineering
The main advantage of the tower type is they can accept more erosive high ash coals. However when any pressure part failure happens in the horizontal sections then it is much more difficult to attend when compared to the two pass design. Both the school of thoughts is present with the boiler designers regarding the advantage of tower type and two pass design of boilers. The main feature of

Drum Type and Once Through Boiler Design - Bright Hub Engineering
Once-through Boiler Characteristics. The once through boiler has high load response characteristics due to the fact that it does not have a drum and has a much lower water inventory. In the once through boiler, many times the load change response is dictated by the firing system and its controls rather than the boiler, per-say.

Why Once Through Boiler | Once Through Boiler
The fire tube boiler will run both units (12 ton/h) while Once Through Boiler will run three units (9 ton/h) and have the fourth unit available as required. Since Once Through Boiler can operate from a cold back-up, (water to steam in 5 minutes, while the fire tube boiler can take hours), the fourth unit can be idle until needed.

Water Levels in Steam Boilers | Spirax Sarco
Water level indication applies to steam boilers where the water level can be detected. It includesmost steam boilers, the exception being those of the once through or coil type, where there is no steam drum. In such cases, steam outlet temperatures exceeding a pre-set value are taken to indicate insufficient water input.
