METHOD OF ORGANIC MATERIALS BURNING AND ASSOCIATED PLANT Russian patent published in 2008 - IPC F24B7/00 

FIELD: heating.

SUBSTANCE: inventions relate to thermal plants for fuel energy conversion to thermal energy while heating rooms. It may be used for heating buildings with square area more than 200 m² by means of one plant. During burning, organic fuel is loaded into drying chamber, which is heated up to 100°C by combustion production available in gas conduit after plant startup. Dry fuel from drying chamber is discharged through fuel pipeline using valves to pyrolysis chamber, which is located in combustion chamber void and heated up to 500°C. When temperature of combustion chamber is increased, gaseous products of pyrolysis are discharged through pipeline to combustion chamber, where they are burnt by supplying air through additional ash-hole. Produced combustion products are used for continuing pyrolysis chamber heating having radiant heat exchanger on the surface. Drying chamber and convective heat exchanger connected with radiant heat exchanger are heated in gas conduit. Solid products of pyrolysis are discharged to after-burner through pipeline and using valves. Heat is removed through chamber wall to accumulator with liquid coolant linked with heat exchanger by pipeline. Cooled gaseous products are removed using bypass to combustion chamber and mixed up with air through additional ash-hole. Heated coolant is removed through proper nozzle.

EFFECT: improvement of combustion effectiveness when carbon drying, pyrolysis and after-burning processes are separated.
