Patent number: 6113662Abstract: A solid burnable fuel composition which contains a major proportion of spent dried coffee grounds is described. The fuel composition includes at least 50% dried spent coffee grounds and a combustible wax which are mixed together and compressed into a suitable shape for combustion. The fuel composition may further include a small amount, 10% or less, of a coking agent useful to control burn rate and to prevent cracking of compressed fuel during combustion. Small amounts of cellulosic material may also be incorporated to improve the structural properties of the composition. Due to its superior heat and flame production, dried spent coffee grounds are an excellent fuel source for processed fuel products such as fire-logs and fuel pellets. The advantage is a hotter, cleaner burn which produces less soot and smoke, releases fewer harmful pollutants and provides a brighter flame over a longer period of time.Type: GrantFiled: May 28, 1999Date of Patent: September 5, 2000Inventor: Rodney K.

Patent number: 5910454Abstract: The present invention relates to a solid burnable fuel composition which contains a major proportion of spent dried coffee grounds for forming into high density pellets, synthetic fire-logs and fire kindling products. A homogeneous mixture of at least 50% coffee, with 30% or less by weight of a combustible binder is compressed and extruded in the form of fire-logs. A pellet fuel comprising entirely coffee provides a higher energy fuel source than prior art fuel sources. Coffee has a higher calorific value than hardwood, providing an efficient fuel material requiring less combustible binder, such as wax, than prior art fire-logs, and offering a higher energy value pellet than wood without added binder.Type: GrantFiled: May 29, 1998Date of Patent: June 8, 1999Inventor: Rodney K.

Patent number: 5112365Abstract: An improved fuel block of compressed combustible particles and a binder has a controlled burn rate preferably for use adjacent citrus fruit trees to prevent frost damage. The fuel block preferably has a cylindrical body and is formed with a longitudinally extending series of individual spaced depressions in the side surface of the body. The side surface of the fuel body is tightly wrapped with a combustible paper which forms air pockets with the side surface of the spaced depressions. These air pockets in combination with the paper, provide a series of alternating fast and slow burn layers which enable the body to burn in progressive layers instead of burning the entire body at the same time. An outer protective plastic wrapper protects the fuel body and wrapper paper from the weather until ready for use. A central hole is formed through the fuel body to assist in the initial lighting of the top surface of the body.Type: GrantFiled: January 25, 1991Date of Patent: May 12, 1992Assignee: Sebring Forest Industries, Inc.Inventors: John E.
