Kcal coal instruments brick machine

Representation instrument brick kcal coal hot card machines automatic calorimeter heat of heat measurement results kJ / g (kJ / g) or MJ / kg (MJ / kg), respectively. 1.2.1 Bomb heat in an oxygen bomb, in the presence of excess oxygen in the case of [the initial oxygen pressure 2.6 ~ 3.0MPa (26 ~ 30atm)], the sample combustion heat generated per unit mass called Bomb heat. Combustion products carbon dioxide, sulfuric acid, nitric acid, is liquid water and solid ash. Note: Any material (including coal) combustion heat, with the combustion products of the final temperature, and the higher the temperature, the lower the heat of combustion. Therefore, a strict definition of the heat, the temperature has to deal with Shao Shao product requirements. However, in actual measurement of heat, due to specific conditions, the end temperature is limited to a specific temperature or a very narrow range is unrealistic. Temperature is increased by 1K, the heat of combustion of coal and benzoic acid was reduced by approximately
