Claim 1
Independent Claim
120 words
THE PROCESS OF CONTINOUSLY RECOVERING LOW TEMPERATURE POTENTIAL HEAT FROM THE GASEOUS PRODUCTS OF COMBUSTION RESULTING FROM THE BURNING OF A PULP RESIDUAL LIQUOR WHICH COMPRISES PASSING SAID COMBUSTION GAQSES THROUGH AT LEAST ONE GAS COOLING ZONE IN DIRECT CONTACT WITH A SPRAYED LIQUID COOLING MEDIUM, COLLECTING THE HEATED COOLING MEDIUM WITH THE MOISTURE CONDENSED FROM SAID GAS AND SUBJECTING IT TO THE EVAPORATIVE COOLING EFFECT OF SUBATMOSPHERIC PRESSURE, CONDENSING THE VAPOR RESULTING FROM THE SUBATMOSPHERIC EVAPORATION OF SAID HEATED COOLING MEDIUM BY HEAT EXCHANGE WITH A COOLING WATER, AND RETURNING THE COOLED RESIDUE OF SAID LIQUID COOLING MEDIUM TO THE GAS COOLING ZONE FOR REUSE AS A COOLING SPRAY AND WITHDRAWING THE COOLING WATER HEATED IN CONDENSING SAID VAPOR.
