Size the boiler according to the required square feet of steam. To do this, you will need to complete a radiator count and measurement. If you measure the height of each radiator, count the
IV. Boiler Steam The production of steam is often done in a boiler, fired by fossil fuels. A boiler can use any heat source, including nuclear, solar, natural gas, coal, wood, waste fuel, or others. Today, most boilers use natural gas simply because it is clean and inexpensive. It has also become a preferred choice because it is a "Clean Fuel".
as follows, "The steam supply/boiler must be cycled on/off by a room thermostat or by an indoor/outdoor reset control." This does not mean for the boiler to cycle off and on by the pressuretrol. Instead, the boiler has to shut down because the thermostat has been satisfied or the reset control has cycled the boiler off…
The design will also allow a specific minimum height of the steam off-take above the NWL. Clearly, as steam is generated, the water in the boiler evaporates, and the boiler must receive a supply of water to maintain the level. Because of the factors outlined above, water must be maintained at the correct level. Safety is also of paramount

All modern boilers have a flame safeguard system which monitors the burner for proper operation and will shut off the fuel supply if a flame is not detected in the boiler. There are different types and these shall be tested periodically.
Oct 10, 2020 · Like a hot-water heating system, a steam system distributes heat via one or more radiators in each room.But while a hot-water radiator can be a slim wall unit or a baseboard convector, a steam radiator is a big, cast-iron hulk, the kind you see in old apartment buildings.Steam boilers are generally reliable, but they should be serviced routinely for the best performance and longevity.
A steam boiler must be fitted with a stop valve (also known as a crown valve) which isolates the steam boiler and its pressure from the process or plant. It is generally an angle pattern globe valve of the screw-down variety. Figure 3.7.3 shows a typical stop valve of this type.
