APPLICATION

Chimney draft regulation, prevents "drafting" through the chimney and overheating of the boiler.

What exactly does this mean???

In coal dust boilers where a blower supports the combustion process, the effect of drafting through the chimney the set temperature on the controller occurs quite often, i.e. we set the boiler to e.g. 60 degrees, the temperature is reached, the controller turns off the blower and the temperature... RISES!!! Air is sucked into the boiler through the blower inlet!!!

What then???

Even the best and most expensive controller cannot cool down the boiler - in such a case it is powerless!!! The boiler burns faster, less economically.

Therefore, a CHIMNEY DRAFT REGULATOR should be installed. The operating principle is very simple, the regulator opens only when the blower is working. If the blower is not working, the regulator closes by itself, without electricity, batteries, etc. It has a mechanical counterweight that always causes it to close!!!

How to check if your boiler needs such a regulator???

Some readers of this description already know they need such a regulator because they have problems maintaining the set temperature on the boiler. For those who want to check - turn off the controller so that the blower stops, light e.g. a lighter and hold it near the blower where it draws air. A regulator will be needed if the flame is blown out by the air being sucked in or if the flame noticeably flickers.

Chimney draft regulators can help save up to 20% fuel.
