How to Calculate Boiler Heat Input Rate | Sciencing

How to Calculate Boiler Heat Input Rate The factor relating these rates is the specific heat capacity of water. Subtract the water's initial temperature from its temperature at the end of the period whose input rate you are calculating. For example, if the water in the boiler rises from 20 to 50 degrees Celsius, subtracting 20 from 50 gives 30 degrees. Multiply the temperature rise by the water's weight in …

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 kBtu/hour (1000 Btu/hour) and can be calculated as

18-06-2014 · Boiler Ratings Explained. Sharing. Published: June 18, 2014 - by Dan Holohan. Categories: Steam, Hot Water. When you look in a boiler manufacturer's catalog you'll see that there are several types of ratings for each boiler. There's the Input rating, the Gross Output rating (which some call the D.O.E. Heating Capacity) and then there's the Net Output rating. You pick one or another to size …
