A ton of water needs 45,000 kcal to increase its temperature by 45 degrees. The calorific value of standard coal is 7,000 kcal. After deducting the boiler efficiency loss and taking into account the difference in coal quality, heat a ton of water from 15 degrees. at 60 It is estimated that at least 10 kilograms of coal should be used. Haha, some say 7 or 8 kilograms is enough. The efficiency of this boiler should be 100%, and the coal should reach the calorific value of standard coal. . In fact, the efficiency of coal-fired boilers is generally about 70-80%, the calorific value of general coal is about 5000-6000 kcal or even less.
