Title: Combustion furnace for pyrolytic analysis - having series of baffles with holes offset to each other
Inventor: BECKER WOLF-JUERGEN DR
IPC: G01N31/12
Filed: 1975-07-31
Abstract: Combustion furnace for pyrolytic analysis of liquids contg a high proportion of salts consists of a tubular furnace and a combustion chamber with branches fro carrier gas, sample injection and outlet for the combustion prods. The combustion chamber is divided up by perforated baffles, the holes of which are offset w.r.t. each other. This causes changes in flow direction as the gas flows from one zone to the next. >=1 of the zones is filled either partly or completely with refractory granules. In the direction of flow, pref. the first and the middle zones should be so filled. For use with the analysis of effluent liq. streams, esp those contg. high concns. of salts. A furnace of this type using quartz tubes is known. However, it is difficulty to construct and thus relatively expensive. The operating life is limited because of a tendency for the quartz to glaze. The furnace described is simple but has a longer operating life. It is thus more economical on both counts.
