Because clean coal is not easy to use.
Rural people who have used it generally believe that clean briquettes do not have enough heat to burn, and it is difficult for the temperature in the house to reach appropriate standards; and clean briquettes often extinguish themselves, making it inconvenient to use; some people also say that burning clean briquettes There will be a peculiar smell when briquetting coal, and in order to keep warm, you cannot open the doors and windows frequently. Therefore, even if clean coal is subsidized, some people still don’t want to use it.
The so-called "clean coal" refers to processed coal products with low sulfur, low ash, and low volatility, which burn more fully and cause less pollution. Logically speaking, clean coal has the advantages of “long and full burning time, quick ignition, and high flame”. At the same time, after subsidies, the price of clean coal is sometimes cheaper than bulk coal.
However, farmers have discovered during use that clean coal not only has "short burning time and incomplete combustion", but also lacks sufficient heat, so some people would rather use loose coal than burn cheaper clean coal.
Precautions when using coal as energy:
1. Keep the combustion environment well ventilated: When using coal burning equipment, ensure that the combustion environment has good ventilation conditions to avoid combustion Harmful gases accumulate indoors.
2. Regularly clean combustion equipment: Regularly clean the dust and cinders inside coal stoves, coal stoves and other combustion equipment to maintain smooth ventilation and thermal efficiency of the equipment.
3. Pay attention to fire source safety: When using coal, pay attention to prevent contact between fire sources and coal to avoid causing fire accidents. Equipment such as coal stoves and stoves should be placed in safe locations to prevent the fire from expanding.
4. Reduce smoke and dust emissions: Coal combustion will produce a large amount of smoke and harmful gases, causing pollution to the environment. Choose efficient combustion equipment and use high-quality coal to reduce smoke and dust emissions.
