What is higher calorific value (HCV) and Lower Calorific Value (LCV)?

What is higher calorific value (HCV) and Lower Calorific Value (LCV)?

Higher Calorific Value (HCV): When the steam in the exhaust gas is cooled to form water. The heat so liberated is adding up to the calorific value of the fuel. Hence, the calorific value in this case is known as higher calorific value (HCV) of the fuel. On the other hand, if the steam is let out along with the exhaust gas the calorific value of the fuel will be less and known as lower calorific value (LCV). For better understanding of analysis of the fuel just go through the other numerical problem given in this blog.
