Boiler Project Fundamentals - AIChE

Low excess air firing can be used on most boilers and generally results in overall NOx reductions of 5-10% when firing natural gas. Low Nitrogen Fuel Oil When firing fuel oils, NOx formed by fuel-bound nitrogen can account for 20-50% of the total NOx level.

Boiler explosion - Wikipedia

A boiler explosion is a catastrophic failure of a boiler. There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level. Corrosion along the edges of lap joints was a common cause of early boiler explosions. The second kind is a fuel/air …

Troubleshooting a Gas-Fired Hot Water Boiler

The ionization electrodes are not making sparks when water is flowing. There are many reasons for this problem and here are some; low gas pressure, the fan speed is low, wire connections are loose, the air in the gas line, no gas. Error code EC – Electrode failure. Ionization electrode failure during water heating. The reasons might be; obstructed venting system, low gas pressure, and CO2 readings, the fan speed …

High Efficiency Residential Gas Boilers | Energy Kinetics

A gas/oil boiler has no inventory or bed of fuel. When you trip the burner, for all practical purposes, the heat input immediately stops. With solid fuel units, however, a fairly large mass of bark, coal, etc., is still on the grate and even though starved of air by the loss of the forced draft fan, these units have more "thermal inertia" and
