The project will seek to develop a residential and commercial logwood-fired boiler with the ability to modulate firing rates down to <10% of rated output while maintaining clean and efficient operation. The boiler will include high levels of insulation in both combustion chambers and preheating of combustion air to promote clean operation at low loads. Forced, multi-port injection and swirl mixing of secondary air similar to natural gas fired burners will be used. Certifications such as UL, CSA, and ASME will be sought.
