When buying this type of fuel, we not only fail to save money but actually incur costs due to the product’s low calorific value. In addition, we contribute to worsening the quality of the air we breathe. But how can we know whether the fuel we buy is good?
Not All Coal Is Good Coal
First and foremost, we need to examine what our supplier offers. Good-quality bagged coal should undergo a stone-removal process, which removes both stones and other contaminants from the fuel. It is also important to check whether the fuel we buy is additionally dried. The more moisture coal contains, the more harmful substances it generates. We should also remember that the calorific value of the bagged coal we buy is not the only parameter to which we should pay attention. The ash content and the Rogi index are equally important—that is, information about how much ash and slag will remain in our furnace after burning the coal. If we have to clean the firebox every day, it means that our fuel is not among the best and we should change it. Another important parameter is the type of coal. When buying bagged coal, choose a type 32.1 or 32.2 product—that is, non-caking coal that does not leave slag in the firebox.
Quality Means Savings
If we decide to burn eco-pea coal, the process of selecting the right fuel should be similar to that for coal. We should check whether the supplier offers eco-pea coal produced from high-calorific coal, with the lowest possible moisture, sulfur content and caking tendency. Let us pay attention to whether the fuel we buy has been cleared of stones and is tightly packaged. Unfortunately, a low price for eco-pea coal does not always mean that buying it saves us money. On the contrary, cheap eco-pea coal may actually generate much higher heating costs. It is worth paying more for better quality, which will ultimately translate into real savings.
