Biodiesel-fired Condensing Commercial Boiler:Biodiesel-fired, Condensing, Commercial Boiler(ST10047-1)

Fulton Heating Solutions


New York State is a major fuel oil consumer, with three million households and businesses (40% of the population) using oil for heat. New York State oil heat customers represent one-quarter of the United States oil heat market. High efficiency, condensing heating systems can help oil heat customers to achieve significant energy and cost savings. Condensing systems can achieve annual savings of 10 to 30 percent compared to standard efficiency heating systems. In past work conducted by Brookhaven National Laboratory (a subcontractor in this project) and funded by NYSERDA, use of biodiesel blended with heating oil has been demonstrated in both the laboratory and existing buildings. Biodiesel blends can be beneficial to help reduce system maintenance and emissions. Commercially available boilers are not designed to burn higher than 20 percent concentrations of biodiesel blends. Conventional, flame safety controls for oil burners seek to detect high-temperature soot radiation in the flame, which is substantially reduced when biodiesel is burned instead of conventional heating oil. Also, other burner components, such as fuel pump seals and electrical wiring, can be vulnerable to material degradation when exposed to biodiesel.

Project Description

Fulton Heating Solutions has developed a gas-fired, condensing boiler for commercial buildings. The boiler is not suitable for use with conventional heating oil due to sulfur-based corrosion problems that adversely affect heat exchanger service life. Fulton Heating Solutions is interested in testing the boiler to determine if it would operate satisfactorily with pure, B100 biodiesel fuel, which contains minimal sulfur. Fulton Heating Solutions will test its gas-fired, condensing boiler with B100 biodiesel fuel and evaluate heat exchanger corrosion performance when fired with biodiesel. The project will include the design, construction, and laboratory testing of a prototype condensing, biodiesel-fired boiler. The project will also include field testing, product certification, and technology transfer by the manufacturer.


The project will benefit New York State oil heat customers and the environment by reducing heating oil consumption for space heating and domestic hot water in large buildings. Economic development benefits also will be achieved through the manufacturing of a new technology in New York State
