Is it generally calculated based on the high or low calorific value of coal gas or coal? Answer: Cold gas efficiency refers to the ratio of the chemical energy of the gas produced by the gasification furnace to the chemical energy of the coal fed into the furnace, and it is generally calculated using the lower heating values of the gas and the coal
The ratio of the chemical energy of the product to that of the raw materials, lower heating value.
Cold gas efficiency = Higher heating value of gas ÷ Higher heating value of coal； The calorific value of gas = calorific value of CO + calorific value of H2 + calorific value of CH4 ； The calorific value of coal = weight of coal × heat release value.
Cold gas efficiency = Calorific value of gas / Calorific value of coal
Answer: Cold gas efficiency refers to the ratio of the chemical energy of the gas produced by the gasification furnace to the chemical energy of the coal fed into the furnace, and it is generally calculated using the lower heating values of the gas and the coal.
Cold gas efficiency: Cold gas efficiency is defined as the ratio of the chemical energy generated by the gas to the chemical energy of the coal used for gasification. It is generally calculated based on the lower heating value of gas or coal.
Cold gas efficiency: Cold gas efficiency is defined as the ratio of the chemical energy of the gas produced by gasification to the chemical energy of the coal used for gasification. The chemical energy of gas and coal can be expressed using their respective lower heating values.
Cold gas efficiency refers to the percentage of the calorific value contained in the product gas compared to that contained in the raw coal; it is generally calculated based on the lower calorific values of both the gas and the coal
Cold gas efficiency refers to the ratio of the chemical energy of the gas produced by the gasification furnace to the chemical energy of the coal fed into the furnace, and it is generally calculated using the lower heating values of the gas and the coal
