ABSTRACT:
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.
