Boiler-Safety Controls - Heating Help

Many installers wonder why the limit control is a manual reset and not an automatic reset control. Well, consider that your operating control is set at 180 0 Fand the limit control is set at 210 0 F.

How to Destroy a Boiler -- Part 1 - National Board of Boiler

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 will continue to produce some heat. The control of the boiler drum level is tricky and even the best tuned control systems cannot always

In the heat recovery boiler, hot process gas is passed through heating pipes. This means the gas is cooled and the necessary process heat for the plant recovered to be reused. To prevent the heat recovery boiler from running dry and thus overheating, reliable monitoring of the water level in the boiler is required.

NOx limits for boilers - ohioepa.custhelp.com

For boilers with a heat input capacity greater than 20 mmBtu/hour equal to or less than 50 MMBtu/hr, there is no specific NOx emission limitation to comply with. However, an annual tuneup of the boiler burners is required. Any boiler with a heat input capacity rating of less than or equal to 20 MMBtu/hour is exempt from the rule.
