INNOVATIVE CONCEPTS FOR WTE AND NATURAL GAS TURBINE POWER PLANTS – AN

ECONOMICALLY FEASIBLE SOLUTION FOR RIO DE JANEIRO.

Dr. Sergio Guerreiro

FINAL DESTINATION OF WASTE IN RIO GRAMACHO LANDFILL 8,000 TON/D

WILL CLOSE SOON

PROBLEM NEW PACIENCIA LANDFILL WAS CANCELLED DUE TO DIFFICULTIES WITH ENVIRONMENTAL LICENSE

USUAL WTE DIFFICULTIESUSUAL WTE DIFFICULTIES

1. HIGH INVESTMENT

2. BOILER CORROSION <-> LOW EFFICIENCY

3.HIGH O&M COSTS

3.LOW ENERGY / TON OF MSW

4. LOW TIP FEE IN MANY PLACES (BRAZIL)

5. CARBON CREDITS CAN HELP

ADVANTAGES OF WTEADVANTAGES OF WTE

1.ONLY VIABLE ALTERNATIVE TO LANDFILLS

2. ENVIRONMENTALLY SUSTAINABLE

3. MATERIALS AND ENERGY RECOVERY

4. CAN BE COMPLETELY CONTROLLED

5. WE CAN AND SHOULD MONITOR EMISSIONS

TRADITIONALLY, RECOVERING HEAT FROM EXHAUST GAS HAS BEEN ECONOMICALLY VIABLE ONLY AT TEMPERATURES ABOVE

THE ACID DEW POINT OF THE GAS. BELOW THIS POINT, COLD-END CORROSION WAS INEVITABLE, RESULTING IN PREMATURE

EQUIPMENT REPLACEMENT COSTS.

UNLIKE CONVENTIONAL ECONOMIZERS AND AIR HEATERS, WHICH MUST MAINTAIN TEMPERATURES ABOVE 300 DEGREES F (149 DEGREES C) TO PREVENT CONDENSATION, THE CHXTM

SYSTEM THRIVES IN A CONDENSING ENVIRONMENT WHERE INLET WATER OR AIR TEMPERATURES ARE IDEALLY LESS THAN 80 DEGREES F (27 DEGREES C), AND EXHAUST GAS EXIT TEMPERATURES ARE ONLY 100 DEGREES TO 130 DEGREES F (38 DEGREES TO 54 DEGREES C).

SINCE THE HEAT EXCHANGER TUBE SURFACE AND THE EXHAUST AREA OF THE HEAT

EXCHANGER ARE AT A TEMPERATURE WELL BELOW THE DEW POINT OF THE WATER

VAPOR, A RAIN OF CONDENSATE IS PRODUCED THROUGH DROPWISE

CONDENSATION OF THE WATER VAPOR. THIS CONDENSATE PASSES AROUND THE TUBE

ARRAY, CARRYING PARTICULATES AND ACIDS WHICH HAVE BEEN SCRUBBED FROM THE GAS AND WASHED FROM THE TUBES.

FROM INLET TO OUTLET, THE EXHAUST GAS CONTACTS

ONLY CORROSION-RESISTANT TEFLON® IN THE CHXTM HEAT

EXCHANGER, ELIMINATING THE CORROSION PROBLEM.
