Thread Content
The last edit to this post was made by Zaihui Kangqiao on 2016-7-8 at 08:39. The Chemical Engineering Theory section is now launching a \"One Question per Day\" activity aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequent series will include those on \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\". We hope for your active support~~~ Answers to the questions in the \"One Question per Day\" activity can be viewed directly; the thread will be closed after 1 day! ! To encourage everyone’s continued participation this year! You get 3 wealth points for participating, and an additional 4 wealth points for answering correctly~~~ Short answer question: What is standard coal?
Standard coal, also known as coal equivalent, is an energy measurement unit with a unified calorific value standard. Our country specifies that the calorific value of each kilogram of standard coal is 7,000 kcal. Energy of different varieties and contents is converted, based on their respective calorific values, into standard coal with a calorific value of 7,000 kcal per kilogram

Standard coal is a fuel for which a specified base lower heating value of Qnet,ar=29271kJ/kg (i.e., 7000kcal/kg) is applied
Standard coal is defined as: any quantity of fuel that can produce 29.27 MJ of heat (lower heating value) is equivalent to 1 kg of standard coal. Standard coal refers to coal with a lower heating value of 29.27 megajoules (MJ) per kilogram on a received basis (equivalent to 7,000 calories).
