Abstract: Disclosed is a potassium humate sulfur compound granule and process for making the same granule. The potassium humate sulfur compound granule including a potassium humate component and an elemental sulfur component at a ratio of about 1:20; where the potassium humate component of the granule fully solubilizes upon application to a desired site and enhances conversion of the sulfur component into sulfate by at least about 15% as compared to elemental sulfur alone.

Abstract: Disclosed is a process for making a fully water-soluble granule comprising humic acid and a microbial community composition. Disclosed also is a fully water-soluble granule comprising humic acid and a microbial community composition. Such a granule is useful as an organic aid to crop growth, particularly in applications where solubility is desirable or necessary.

Abstract: The present invention is a method of optimizing radiant and thermal efficiency of a gas fired radiant tube heater. A heat exchange blower receives intake air and delivers intake air through a heat exchanger as pre-heated air to a combustion air blower. The combustion air blower receives pre-heated intake air from the heat exchanger and then provides the pre-heated intake air to a burner for mixing with fuel. The fuel-intake air mixture is burned in the burner thereby producing combustion gasses which are fired into a radiant tube. The exhaust combustion gases pass through the balance of the radiant tube and through the heat exchanger where residual heat is transferred and extracted from the combustion gases to pre-heat the intake air. The turbulators are configured to increase the turbulence within the radiant tube and are placed within the initial 10? to 30? of the radiant tube after the burner to increase the tube temperature and the radiation emitted from this section of the radiant tube.

Abstract: The present invention provides highly water soluble products derived from humin, as well as methods of obtaining such products. Humin is first blended with water and a nitrogen source, such as urea, under intense agitation and heating, in order to disperse the nitrogen source. Thereupon, the blend is incubated for an extended period to create nitrogen-reacted humin having the desired solubility properties. The products may be used as aqueous dispersions, or dried in the form of particulates.

Abstract: Improved methods and apparatus (10, 74) for the solubilization of initially solid humic acids include a large-volume mixing/agitation tank (12, 76) for water and solid humic acids, together a recirculation assembly (14, 78) for continuously recirculating the water/humic acids mixture while reducing the size of the humic acids. Properly used, the apparatus (10, 74) is capable of providing relatively stable, solubilized humic acid solutions or dispersions.

Abstract: The present concept is a radiant tube assembly that includes a burner assembly firing combustion gases into a combustion tube which emits radiant heat energy from its outer surface. A black ceramic coating is applied the outer surface of the combustion tube to increase the emissivity of the combustion tube and lower the temperature of the outer surface of the combustion tube. Semi-circular top and semi-circular bottom inserts extending longitudinally along the length of a first section of the combustion tube lower the combustion tube outer temperature.
