Features of good coal

Coal is still the most common type of solid fuel. It provides high efficiency of heating installations, is economical, and in the case of modern boilers it can also be energy-saving and environmentally friendly. All this is provided that we choose high-end fuel. What parameters should a good coal have? What should you pay attention to when buying fuel?The most important parameters of coal
There are many types of coal on the market, varying in size, granulation, and composition. The main indicators of coal quality include:Calorific value - The calorific value of coal determines the amount of thermal energy that can be obtained from a given amount of fuel. The more calorific the coal, the more energy efficient its combustion will be, which will reduce heating costs. The calorific value depends on various factors such as the type and origin of the coal. High-quality coal has excellent calorific value, although high-quality coal from the Czech Republic and even from Colombia is also available on the market.
Sinterability – this parameter determines the degree of adhesion of individual pieces of coal, which leads to the formation of carbon deposits and tar deposits in the boiler. For domestic heating systems, it is recommended to use coal with a lower sintering level.
Sulfur content and ash content - the less of these substances in coal, the "cleaner", i.e. the more environmentally friendly the combustion will be. The high sulfur content means that burning such fuel will lead to increased exhaust emissions, which means more environmental pollution. The same applies to ash, the high content of which also requires more frequent cleaning of the boiler.
Humidity. Good coal should be kept as moist as possible, which will make its combustion more efficient.
How to buy good coal?
Summarizing the coal parameters discussed above, it can be stated that high-quality fuel should be characterized by high heat of combustion and, at the same time, low humidity, as well as sulfur and ash content. But that's not all. What else should you pay attention to when buying fuel?The coal must be clean, i.e. free of scale and dense. You must also choose the right assortment. Peas or walnuts are ideal for traditional boilers, and a special device is required for small coal.When choosing a fuel warehouse where we will purchase coal, it is worth paying attention to the method of storing fuel, as well as the possibility of purchasing in bulk and delivering the purchased goods.
