Officers report that, under Resolution No. XLI/1407/17 of November 30, 2017, the following were also banned:
- coal sludge and coal flotation concentrates, as well as mixtures produced using them
- lignite and fuels produced using this coal
- fine-grained hard coal with a particle size below 3 mm
- solid biomass with a moisture content above 20%.
Municipal Police:
Experience shows that not only violations of the above bans are a problem, but also improper lighting of the furnace. Very often, it turns out that troublesome smoke is produced precisely when the fire is being lit and persists for several minutes, after which the problem disappears.
During inspections of fuel burning carried out by municipal police officers, it often turns out that residents do not know what proper lighting involves—so-called top-down lighting.
This simple and completely cost-free burning technique makes it possible to burn coal and wood without producing smoke and makes the combustion more efficient.
How do you light a fire from the top?
The whole process involves moving the layer of embers from the bottom to the top of the firebox. Air still flows upward from beneath the grate, while the embers gradually move downward. (When lighting from below, they moved upward.)
This time, however, smoke escaping from the still-cold layer of fuel passes through the embers, where it is almost completely burned. As a result, nearly transparent exhaust gases enter the chimney, and burning the smoke produces more heat.
The officers add:
We therefore encourage the residents of our city to pay attention to how they light their furnaces because, as you can see, such a small change can make a very significant difference and contribute to improving air quality. Not only in our immediate surroundings, but also throughout the city.
Regardless of the above, it is also important to remember the obligation to carry out periodic chimney inspections, because the condition of the chimney also affects what comes out of it and has an impact on our safety.
