### Boiler Capacity - Engineering ToolBox

Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtuhour (1000 Btuhour) and can be calculated as

Nov 14, 20170183;32;Proper hot water boiler sizing. Since the radiation is already installed on a retrofit installation, you wouldn't need to do a room-by-room heat loss but instead, an envelope heat loss. Then, choose a boiler using the DOE output, not the net output. There are plenty of wrong ways to pick a boiler, like copying the size of the existing boiler,

Jun 23, 20140183;32;If you have more piping and radiation than you have steam to heat it, the steam won't make it to the end of the run. You'll wind up with a cold house that costs a lot to heat, and inadequately at that, but I think you're making a mistake if you size a replacement hot water boiler that way." He shook his head.

The form and size depends on the application: mobile steam engines such as steam locomotives, portable engines and steam-powered road vehicles typically use a smaller boiler that forms an integral part of the vehicle; stationary steam engines, industrial installations and power stations will usually have a larger separate steam generating facility connected to the point-of-use by piping.

Boiler size describes the heat output of a boiler in energy units, not the physical size of the boiler. Manufacturers measure boiler output in British thermal units (BTUs) per hour or boiler horsepower (BHP). BHP measurements usually only apply to very powerful and large capacity boilers, since one BHP equals 33,475 BTUs per hour.

The receiver size on boiler feed units is typically based on the total system load of all boilers fed by the boiler feed unit with 20 minutes GROSS storage. The size of boiler feed receivers are expressed in gross gallons. Make sure the inlet height is lower or equal to exisiting height on gravity return systems. Water does not run uphill!
