Comparison of the working principle of a time-burning and long-burning stove

The continuous firing furnace or perennial is according to DIN EN 13240 an appliance for solid fuels , with the fuel logs a burnup can hold at least 90 minutes, as well as with a mineral fuel such as brown coal briquette can last for at least 240 minutes.

function

In contrast to the time- burning stove, a long- burning stove is optimized for burning coal , but can also be operated with firewood .

The long-term burnability can be recognized by the design of the combustion chamber . In the bottom of the combustion chamber there is a cast trough in which the coal can slide and burn off optimally. In principle, like the time- fired furnace , the furnace can work continuously around the clock.

history

Orders under Palatine Count Karl IV. From 1772 also served to prevent fire in connection with domestic fireplaces. According to simultaneous building regulations, no more wooden chimneys were allowed to be erected, no more wooden hoses were allowed to be installed that had to lead the smoke from the fireplace to the fireplace, just as it was forbidden to lead stovepipes out of the window.
