Boiler Cheat Sheet - Novatherm

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. W = (hg - hf) m (1) where. W = boiler capacity (Btu/h, kW)

Calculating Boiler Chemical Requirements – Water

Jun 26, 2017 · "H" and "M" values are determined as calcium carbonate from feed water analysis. Example: Field tests on a given feedwater show H = 84 ppm and M = 59 ppm. Non-carbonate hardness (H-M) = 25 ppm as CaCO 3. Assume boiler operates at 10 cycles of concentration, and the residual boiler water alkalinity, M, is 250 ppm.

Natural Gas Fired Boilers

The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and
