Heating unit and fertilizer preparation

The method of providing heat and plant nutrient for agricultural areas by the following steps:

• mixing into a mass at least one organic material to provide a combustible, fuel-absorbing material,
• a fuel to provide heat during fire burning, and
• at least one inorganic material to provide a force means at the surface during fire burning,
• compressing said mass into a solid, and
• igniting the fire burning surface to protect agricultural areas by heating said areas and to remove surface particles from said mass to continue the surface burning and provide agricultural plant nutrients.

A heating unit comprising:

• a mixture of organic material,
• inorganic material, and
• liquid fuel that supports surface fire burning,
• said mixture of said organic, inorganic materials and fuel compressed into a generally stable solid, holding as much as 75 percent of the mixtures weight in fuel,
• said solid including an ignitable air exposed surface,
• said mixture providing means to control the flow and transfer of heat outward from the surface and the length of burn,
• said mixture providing additional force means for cleansing of the fire burning surface of spent material to insure a generally constant intensity and rate of burn, said spent material falls into a heap at the foot of said solid heating unit to the destructive deterioration of the mass and the increase in particle size of the left-over force means, whereby the force means are saturated and fixed by the burn gases and inorganic material and are slowly distilled to alter or change the materials to form useful fertilizer, soil conditioner and plant nutrients.

A mass including a dense-unexpanded inorganic ore of the non-metallic mineral vermiculite or perlite or the like for producing useful heat and plant nutrients comprising:

• a mass of a blended and formulated material having a fire burning surfce including,
• fuels to produce heat by burning to produce at least 100,000 BTU input per 100 pounds of mass,
• inorganic materials of known sources of plant nutrients, and
• said inorganic materials including a force means of a dense unexpanded inorganic ore of the non-metallic mineral vermiculite or perlite or the like, and
• said vermiculite or perlite or the like included in sufficient quantity and dispersed throughout the mass to provide upon being heated by the fire burning surface an expanding vermiculite or perlite or the like at the fire burn surface to act by force to provide a relatively clean fire burn surface and to eventually cause self-destruction of the mass by removing portions of the materials from the mass, and to provide a platey, laminated, porous, absorptive structure cavity means to hold and be saturated by gases from the heat distilled fuels and other materials and free nitrogen from the air after oxygen is used to support combustion at the fire burn surface for providing improved plant nutrients from the removed materials and gases.

A method of producing heat by continuous surface combustion by fire of a mass by mechanical self-deterioration of the mass by the steps of:

• mixing an organic material including combustible fuel, inorganic material, and a force means of inorganic ore of the non-metallic mineral vermiculite or perlite or the like into a mass, to provide a surface that supports combustion by fire.
• said vermiculite or perlite or the like included in sufficient quantity and dispersed throughout the mass to provide proper surface cleaning to prevent extinguishing the fire on the burning surface,
• igniting the surface of said mass to provide a fire burning surface,
• said vermiculite or perlite or the like upon being heated by the burning surface will expand in and about the burn surface and the act of expansion will mechanically cleanse the burning surface of surface materials, whereby said mass gradually self-deteriorates and each layer of surface is exposed for burning in the atmosphere.
