Boiler Purge Causes Explosion | Martin Thermal Engineering

2016/11/9 · The failure mode occurs only in heating systems equipped with natural gas burners and flue gas recirculation (FGR) for control of NOx emissions. The investigation where the failure mode manifested itself happened to be concerned with a boiler explosion, but ovens, furnaces, and fluid heaters are equally capable of experiencing the same problem, if certain factors are in play.

Boiler Efficiency - an overview | ScienceDirect Topics

Typical boiler efficiencies range from about 90% for the best solid biomass fuel boilers to close to 95% for oil- and natural gas-fired boilers, Table 3.2. The main reason for the poorer performance of biofuels is the high moisture content of the fuel, which increases flue gas losses.

Determining & Testing Boiler Efficiency for …

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
