3DJH 3ULQFLSOHV RI &DORULPHWULF 0HDVXUHPHQW To make a calorimetric measurement, a sample of a substance is burnt. In order to ignite the sample, energy must be supplied from an external source. An ignition wire, which is heated to glowing point by passing an electric current through it, performs this function. If the measurement is to be accurate, it is essential that the sample is completely burnt. For this reason, combustion takes place in an atmosphere of oxygen at a pressure of 30 bar.
3ULQFLSOHV RI &DORULPHWULF 0HDVXUHPHQW 3DJH *URVV FDORULILF YDOXH +R The gross calorific value Ho is obtained by dividing the heat energy released by burning a solid or liquid fuel by the weight of the sample.

3ULQFLSOHV RI &DORULPHWULF 0HDVXUHPHQW 3DJH &RUUHFWLRQV It is intrinsic to the method that during a combustion test heat is released from external sources as well as from the sample.

3DJH $FLG FRUUHFWLRQ Almost all substances that are tested contain some sulphur and nitrogen. Under the conditions employed for calorimetric measurements, sulphur and nitrogen burn to SO2, SO3 and NOx. In combination with water from combustion and moisture from the sample, sulphuric acid and nitric acid are formed and heat of solution is developed. The influence of the heat of solution must be taken into account when calculating the standard calorific value.
3ULQFLSOHV RI &DORULPHWULF 0HDVXUHPHQW 3DJH &DOLEUDWLRQ For the most precise results, the calorimeter should be calibrated during commissioning, following service work, when parts have been replaced, and at defined intervals. The purpose of calibration is to re-determine the thermal capacity of the calorimeter system (C value).
