MULTI-TUBE HEAT TRANSFER SYSTEM FOR FUEL COMBUSTION AND HEATING OF PROCESS FLUID MEDIUM AND ITS USE Russian patent published in 2010 - IPC F23C99/00 

FIELD: heating.

SUBSTANCE: group of inventions refers to heat transfer system for fuel combustion and heating of process fluid medium or to the heat transfer system used at non-flame fuel combustion for direct heating of process fluid medium. The effect is achieved in four-tube heating system for fuel combustion and transfer of heat released as a result to process fluid medium. Heating system includes fuel introduction zone, combustion zone, oxidiser introduction zone and process fluid medium zone. At that, fuel introduction zone is comprised by fuel introduction to combustion zone which is formed by a reaction tube which is located outside the fuel introduction device and envelopes it; at that, oxidiser introduction zone is formed by an oxidiser introduction tube located outside the reaction tube and enveloping it; at that, process fluid medium zone is formed by a process tube located outside the oxidiser tube and enveloping it.

EFFECT: providing combustion intensification with increase of fuel combustion efficiency and direct transfer of heat released as a result to process fluid medium.
