Water Handbook - Boiler Blowdown Control | SUEZ

There are many mechanical factors that can affect the blowdown control limits, including boiler design, rating, water level, load characteristics, and type of fuel. In some cases, the blowdown control limits for a particular system may be determined by operating experience, equipment inspections, or steam purity testing rather than ASME or ABMA water quality criteria.

How to Destroy a Boiler -- Part 1

A gas/oil boiler has no inventory or bed of fuel. When you trip the burner, for all practical purposes, the heat input immediately stops. With solid fuel units, however, a fairly large mass of bark, coal, etc., is still on the grate and even though starved of air by the loss of the forced draft fan, these units have more "thermal inertia" and will continue to produce some heat.

Boiler - Factorio Wiki

Boiler. The boiler is used to convert water into steam. When fueled it converts feed water into steam at 165°C, matching the maximum temperature of the steam engine. Boilers have 2 water connectors, allowing them to pass water through to other adjacent equipment, but only 1 steam connector for output. 1 unit of steam is produced for each unit
