Safety controls for any fuel gas fired boiler

If the natural gas pressure control valve fails, excessive gas can flow to the burner. If too much natural gas flows to a combustor, the burner could go out or the flame could be large enough to cause overheating. If the flame goes out and natural gas continues to flow, a combustible mixture could fill the boiler combustion chamber (explosion

How to Destroy a Boiler -- Part 1

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

Gas Flame Thermocouple Sensors Troubleshooting & Replacement

Many modern gas fired heating appliances, boilers, furnaces, water heaters, use an electronic ignition or spark to light the pilot. On these appliances there may still be a thermocouple to confirm that there is a good gas flame when the burner is on - since we don't want to continue supplying gas if there is no flame (doing so risks an explosion).

Improve Your Boiler's Combustion Efficiency

A boiler operates for 8,000 hours per year and annually consumes 500,000 million Btu (MMBtu) of natural gas while producing 45,000 lb/hour of 150-psig steam. Stack gas measurements indicate an excess air level of 44.9% with a flue gas minus combustion air temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1).

What Should You Do Before Starting Boilers After Summer

Readings on flame signal strength meters (if fitted) should be observed and recorded in the boiler log. A normal shutdown should be initiated by opening the manual burner switch. After the post purge has been completed, check the furnace for flame cutoff and make sure there is no residual flame in the furnace.
