Boiler rating is the heating capacity of a steam boiler; it is expressed in BTU per hour (BTU/h), horsepower (hp), or pounds of steam per hour. The oldest method of rating boilers, still used to rate small boilers, is by boiler horsepower. One boiler horsepower is defined as the ability to evaporate 34.5 lb. of water into steam …

suijitupian191.jpg" />14/2/2019 · Once the total amount of steam is known, it is very simple to determine boiler power. Simply divide the total amount of steam required by either 15.9 kg/boiler hp or 35 lbs/boiler hp (depending on units used). This will calculate the minimum required …
suijitupian155.jpg" />Boiler rating (kW) = Steam output (kg/h) / ( (3600 s/h) / (added energy in kJ/kg)) "From and at" rating. This rating is commonly applied as a datum simply by steam boiler makers to provide boiler rating that indicates the quantity of steam in kilo gram per hour (kg/h) that boiler may generate at atmospheric pressure, "from and at 100°C".

suijitupian47.jpg" />Boiler horsepower - a power unit from the 19 th-20 th centuries - was used to rate the capacity of a boiler to deliver steam to steam engines. A common definition of one boiler horsepower is the amount of energy required to produce 34.5 pounds (15.65 kg) of steam per hour at pressure and temperature 0 psig (0 bar) and 212 o F (100 o C) - with feed water at pressure 0 psig and temperature 212 o F.
suijitupian67.jpg" />Boiler water treatment is done to minimize corrosion, deposition, scale, and carryover in the water–steam circuits. The aim is to maximize the reliability of the steam–water circuit. Boiler water treatment has basically two phases: First, we remove impurities from the water to the desired cleanliness.
suijitupian149.jpg" />Boiler Ratings and Boiler Load The oldest method of rating boilers, still used to rate small boilers, is by horsepower (hp). One horsepower is defined as the ability to evaporate 34.5 lbs of water into steam at 212 deg. F and above. Large boiler capacity is generally

suijitupian64.jpg" />A boiler that could evaporate 30 pounds of water per hour from an initial water temperature of 100º Fahrenheit into steam at 70 PSIG would be rated as one boiler horsepower. Today the definition has been changed to reflect a boiler's ability to evaporate water.
suijitupian4.jpg" />For an average steam boiler, less than 1% of the losses are due to heat radiated from the boiler shell (for example: 1% of the Maximum Continuous Rating (MCR) of the boiler). If a boiler is then producing 50% of its MCR, the losses due to radiation are 2% relative to its production rate.
