Fuel. The National Fire Research Laboratory (NFRL) operates calorimeters to measure the heat and combustion products for fires in the range of 50 kW to 20,000 kW The National Fire Research Laboratory The National Fire Research Laboratory (NFRL) is a unique experimental facility dedicated understanding fire behavior and structural response to fire. Combustion systems consist of many different gases, so the thermodynamic properties of a mixture result from a Two other terms that need consideration of this point are (1) the gross heating value and (2) the net heating value (Table 4.11).The gross heating value is the total energy transferred as heat in an ideal combustion reaction at a standard temperature and pressure in which all water formed appears as liquid.
