METHOD AND APPARATUS TO REDUCE THE CONTENT OF SULFUR DIOXIDE IN FIREPLACE GASES.

摘要

A METHOD AND APPARATUS ARE USED TO REDUCE SULFUR DIOXIDE PRODUCED BY THE COMBUSTION OF A SULFUR-CONTAINING FUEL IN A COMBUSTION CHAMBER. PART OF THE COMBUSTION AIR IS INTRODUCED IN THE COMBUSTION CHAMBER NEAR THE FUEL. ANOTHER PART OF THE COMBUSTION AIR IS INTRODUCED IN THE CHAMBER OVER AND UNDER THE FUEL CURRENT, AND RELATIVELY AWAY AND UNDER CONDITIONS TO TEMPER THE FLAME FRONT AND REDUCE THE TEMPERATURE OF THE POINT OF THE FLAME. LIMESTONE PARTICLES FINALLY DIVIDED OR ASPIRED WITHIN THE COMBUSTION CHAMBER BY COMBURENT AIR, AND DISTRIBUTED AMONG THE COMBUSTION GASES, WHERE THEY CALCINATE PARTICLES OF LIME, WHICH REACT WITH THE SULFIDE DIOXIDE PRODUCED. PARTICLES AND AIR ARE NOT MIXED BEFORE ENTERING THE CHAMBER. SEVERAL PARAMETERS ARE CONTROLLED TO OBTAIN THE DESIRED RESULTS.
