Publication number: 20170146245Abstract: An improved fire grate may provide fresh oxygen rich air to a secondary combustion zone, created by the improved fire grate, of a combustion chamber where a combustion gas stream is typically oxygen starved assisting in the burning process of incompletely burned particulates and reducing other harmful emissions. A baffle plate may be introduced in the secondary combustion zone to increase a combustion chamber temperature, encourage mixing of oxygen starved air with oxygen rich air and increase a residence time of the combustion gas within the combustion chamber. These aspects of the baffle plate promote more efficient burning of the biomass/fuel. Additionally, log lighter(s) may be disposed in the secondary combustion zone to increase a temperature of the combustion chamber for the purposes of reducing harmful emissions. The improved fire grate may be horizontally and vertically adjusted to fit within different sized fireplace combustion chambers.Type: ApplicationFiled: February 2, 2017Publication date: May 25, 2017Inventor: STEVE MARPLE

Publication number: 20150168015Abstract: The present invention is directed to several embodiments or variations of a fire grate system for a low-emission outdoor fire pit or fire ring. Several of these variations use the same fundamental fire grate framework within the system and are adapted burn liquefied petroleum gas (LPG), a common example of which is propane. A first embodiment of the invention may simulate a wood fire without burning wood by securely attaching artificial ceramic (or similarly constructed) fire logs to a LPG gas-burning fire grate framework. A second, alternative embodiment of the present invention is a gas/wood hybrid system and that uses LPG fuel to reduce emissions from a wood fire.Type: ApplicationFiled: December 17, 2014Publication date: June 18, 2015Inventors: STEVE MARPLE, ALBEN T.
