Radiative heating pyrolysers

Laser pyrolysers are practically the only type of radiative heating pyrolyser with certain applicability. Attempts were made in the past to use a strong light/heat source and... 

The nature and distribution of pyrolysis products from a particular sample critically depend largely on the pyrolysis temperature and the specific set of pyrolysis conditions (i.e. temperature rise time, sample size, pyrolyser geometry). Laser pyrolysers are practically the only type of radiative heating pyrolyser with certain applicability. A laser pyrolyser consists of five components (i) laser (ii) fibre optics (Hi) probe for sample introduction (iv) pyrolyser body, containing the pyrolysis chamber and (v) heater of the pyrolysis chamber with dedicated control unit. The laser beam can be focused onto a small spot of a sample to deliver the radiative energy. This provides a special way to pyrolyse only a small portion of a sample. Only the sample itself is... 

There are several construction principles for pyrolysers, such as inductively heated, resistively heated filament, furnace type, and radiative heated. The principles of construction for the main types of pyrolysers will be discussed in Section 4.2 to Section 4.6.
