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 …

Babcock & Wilcox Boilers - Nationwide Boiler Inc.

This allows the FM boiler to be a very rugged and long-life boiler that fits most industrial boiler applications. Babcock & Wilcox FM D-type boilers can be configured as left or right hand, and can be designed for a steam capacity of 10,000 to 300,000 lbs/hr, pressures from 250 to 1,250 psig, and a maximum temperature of 850F (for gas fired units).

Gas-Fired Boilers - Code Compliance Brief | Building America …

A boiler typically uses a fuel such as natural gas, propane, or fuel oil in a vented combustion chamber, much like a furnace. Whereas a furnace directly transfers heat from combustion to supply air in the air distribution unit, a boiler heats a secondary transfer fluid (typically water, but sometimes steam) that is, in turn, pumped through a radiation/convection system located throughout a
