INTERNATIONAL CLEANER PRODUCTION INFORMATION CLEARINGHOUSE

CASE STUDY # 111

1.   Headline:  New technology allows oil fired furnace to be
     more energy efficient

2.   Background:  See below.

3.   Cleaner Production Principle:  new technology

4.   Description of Cleaner Production Application:
     Retrofitting oil-fired heating systems with special air
     mixing tube, positive damper control, fuel shut-off valve
     to improve energy efficiency and to reduce emissions.  The
     changes to a conventional oil-burning furnace are:

     1.     Replace air mixing tube
     2.     Install smaller nozzle
     3.     Solenoid shut-off valve in fuel line
     4.     Positive damper in stack
     5.     Interlocking wiring

     Benefits range from 15-20% fuel cost reduction.

     Material/Energy Balance and Substitution

     WASTES: Emissions of CO, particulates, and hydrocarbons.

5.   Economies

                              COST:                (1979
                              Canadian Dollars)

                              CAPITAL COST:         $400

                         MONTHS TO RECOVER: 36 to 84

6.   Advantages

     FEEDSTOCK REDUCTION:    20%

     WASTE PRODUCTION:       9% reduction in SO2 and NO2

     IMPACT: Reduces fuel consumption and waste emissions

7.   Constraints:  No information provided.

10.  Reviewers Comments:  This case study was originally
     abstracted for the US EPA Pollution Prevention Information
     Clearinghouse.  It underwent a UNEP IE funded technical
     review in 1994 for quality and completeness. It was edited
     for the ICPIC diskette in July 1995.
