Types of Exhaust Gas Boiler (EGB) Fires and Ways to Prevent Them Soot is deposited in the water tube of the exhaust boiler. When the ship is at slow speed, the exhaust temperature of main engine may vary from 100 to 200 deg C. This temperature is enough to ignite “wet soot” whose ignition temperature is around 150 deg. C.

Condensing boilers direct-vented exhaust a concern

But to tell you the truth, with radiators, I would not hesitate recommending the gas condensing/modulating boiler like the GB-142 over the oil boiler. But it depends on what else the boiler will be heating, like domestic hot water, fin tube baseboard, fan coils, etc. Use the Find a Pro feature on this site to find a good contractor to help you!

15 Ways to Increase Boiler Efficiency in Your Facility

Oct 01, 2018 · Think about it; the boiler draws in cool air, heats it up, and sends it out the stack. A lower stack gas temperature is ideal because the higher the temperature, the more energy leaves with the flue gas. On the other hand, the boiler system takes in cold water, heats it to steam, and uses the heat.
