摘要：Coal is formation media of Methane Gas which retains the ability to store gas in large quantities.Methane gas (CH4 ) one of the greenhouse gases that its existence can be troubling,because the gas can increase the impact of global warming,the can damage the ozone layer and increase the temperature of the earth.Methane gas (CH4 ) emissions occurred in the coal combustion process were strongly influenced by the physical and chemical of coal.This research was intended to know how the influence of quality parameters and calorific value of coal methane gas (CH4 ) emission,and temperature in combustion process.This research is quantitative research with method of quantitative descriptive and descriptive associative approach.Average methane gas emissions (CH4 ) occurring for each calorific value of coal calories: 3.98 ppm from 5900 kcal/kg,1.30 ppm from 6300 kcal/kg,0.26 ppm from 6700 kcal/ kg,and 0.08 ppm from 7600 kcal/kg.The relationship of temperature,calorific value and methane gas emission (CH4 ) is the higher the calorific value,the required temperature will be higher and the gas emission smaller: for the calories of 5900 kcal/kg,the average temperature was 63.75o C;6300 kcal/kg,60.92o C;6700 kcal/kg,52.59o C,and 7600 kcal/kg,113.98o C,respectively.Indonesian coal mostly consists of low rank coal which can cause high methane (CH4 ) emissions that would also cause problems to the environment.
