Learn MoreSizing a Steam Boiler. December 5, 2017. By Ron Beck, U.S. Boiler Company. Last month we discussed sizing a hot water boiler with a heat loss calculation. Unlike a hot water boiler, a steam boiler is sized by determining the square foot of radiation connected to the steam system. Once that's been determined, you can accurately select a boiler

Learn MoreBoiler sizes, or outputs, are measured in Kilowatts, or 'kW' for ease.. For an interactive way of calculating the size of boiler that your home requires, use our 60 second online quoting tool.You'll see fixed prices on boilers which are the perfect power for your home's needs.

Learn MoreControl Valve Sizing. The successful operation of process plant and systems involves the highest level of measurement and control performance. Control valves therefore perform a key function in this process. The performance of control valves can have a dramatic effect on plant operating efficiency, overall profitability and asset life cycle costs.

Learn MoreConsider the system shown in Figure 10.2.6, and determine the pipe size required from the boiler to the unit heater branch line. Unit heater steam load = 270 kg/h. Although the unit heater only requires 270 kg/h, the boiler has to supply more than this due to heat losses from the pipe. The allowance for pipe fittings. The length of travel from

Learn MoreThe boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.

SIZING HOT WATER DEMANDS The information on sizing the potable water (cold & hot water) is defined in the American Society of Heating, Refrigeration and Air Conditioning Engineers ASHRAE 1991

Learn MoreBoiler 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.
