Advanced Venting System for High Efficiency Oil-fired Boilers. (ST10746-1)

National Oilheat Research Alliance dba


Nearly three million households (almost forty percent of the population) and numerous businesses in New York State use almost two billion gallons of fuel oil per year for heating. Lower sulfur (500 ppm and 15 ppm) types of heating oil will likely be introduced to New York State over the next decade if anticipated environmental regulations are implemented. Lower sulfur heating oil can enable the use of lower cost, natural gas-type, condensing heat exchangers to achieve higher efficiency and reduced fuel consumption. Remaining concentrations of fuel sulfur (in 500 ppm S heating oil) as well as minimum firing rate requirements for oil burners (typically 0.65 gph), along with a trend toward the use of modulating firing rates with high flue gas temperatures (300-350 degrees F) under full-load conditions, will likely continue to prevent the use of natural gas-type venting systems. There will be a continuing need to develop lower cost venting concepts that enable the more economical, widespread introduction of high-efficiency, oil-fired heating systems.

Project Description

The project will perform an evaluation of concept that incorporates supplemental dilution (with outside air) of appliance exhaust to reduce mixed flue gas temperatures that are within the operating range of PVC and/or polypropylene plastic materials. Similar supplemental-dilution concepts have begun to appear in the gas-fired appliance market and could potentially be adapted to the oil heat market. Phase I of the project will perform design and laboratory testing of the vent concept. Phase II will incorporate field testing and UL product certification. If successful project results are achieved, the technology would be commercialized by ProTech Systems, Inc., of Albany, New York.


Benefits include: •Reduced cost for high-efficiency, oil-fired heating systems •Reduced fuel consumption from more widespread use of high efficiency systems •Creation of manufacturing jobs
