Additive (such as coal calorific value enhancer) improves the combustion efficiency or calorific value performance of coal through physical or chemical means, resulting in an increase in calorific value during testing. The specific reasons are as follows:

1. ‌Physical effects‌

• ‌Moisture reductionAdditive may reduce the moisture in coal through drying or adsorption, indirectly increasing the effective calorific value (as moisture evaporation consumes heat)

• ‌Ash optimizationSome additives can reduce the residual ash content after combustion, thereby increasing the calorific value per unit mass

2. ‌chemical action‌

• ‌Combustion promotionSome chemical reagents (such as thiourea and silicon fluorine) can accelerate the coal combustion reaction, release more energy, and improve the measured calorific value

• ‌Fuel conversionAdditive may catalyze the reaction between coal and steam to produce water gas (CO+H ₂), and the addition of hydrogen will increase the calorific value of the mixed gas

3. ‌Detecting interference‌

• ‌Additive characteristicsSome card extenders themselves contain high calorific value components (such as organic matter), which directly participate in combustion and contribute heat, resulting in higher laboratory results

• 

• There are several types of coal based card extenders:

Thiourea additives: These additives can improve the combustion efficiency and ash stability of coal, and effectively suppress the pollution of sulfur dioxide produced by coal combustion to the environment.

Silicon fluorine additives: Silicon fluorine additives can effectively improve the low-temperature combustion performance of coal, reduce the ash content and volatile matter of coal, and decrease the amount of ash generated during coal combustion.

Organic polymer additives: These additives can improve the thermal stability and combustion performance of coal, and reduce the emissions of carbon dioxide and nitrogen oxides produced by coal combustion.

Nitrate additives: Nitrate additives can improve the thermal efficiency and combustion efficiency of coal, while reducing the emissions of sulfur dioxide and nitrogen oxides produced by coal combustion.

In addition to the chemical additives mentioned above, there are also some physical additives such as coal tar, coal tar pitch, coke, naphtha, etc., which can increase the combustion temperature, combustion rate, and flame temperature of coal, thereby improving its calorific value, that is, high calorie value. These additives can make coal combustion more efficient, improve fuel utilization, and reduce exhaust emissions from combustion.

Please note that when using coal based additives, it is necessary to strictly follow the prescribed dosage and method to ensure their optimal performance during coal combustion. At the same time, attention should be paid to the impact of additives on the environment and human health.
