Abstract: Methods, systems, and kits directed to improving combustion processes. In one embodiment, a method includes applying air to an internal surface of a combustion system. The air may be applied with a velocity chosen from about 50 m/s to about 300 m/s, and a volumetric flow chosen from about 50 ACFM to about 4000 ACFM. At least one FCT chemical may be optionally fed with the injected air in this embodiment.

Abstract: A slag and corrosion control process is described. The process entails: identifying the location of at least one slagging problem area in a boiler; introducing a slag control chemical comprising magnesium oxide or hydroxide into combustion gases in a location identified as having a slagging problem; identifying the location of at least one corrosion problem area in a boiler; and introducing a corrosion control chemical comprising a sulfate salt, bisulfite salt, sulfuric acid, or sulfur into combustion gases in a location identified as having a corrosion problem. In operation, these slag deposits will be sufficiently friable to be removed by relatively moderate application of physical energy, thus saving time and reducing any damage to the tubes by the cleaning process. The slag deposits are less voluminous and less in weight and are removed quickly. It is an advantage of the invention that slag can be removed with little or no shut down of a boiler.

Abstract: A system for designing houses according to a consumers specifications is described herein. The system allows building design element vendors such as housing component manufacturers, developers, designers and service providers to contribute detailed agreements about their products or services to a central service provider. The agreements include data which is used to modify the available options and features displayed at a home page maintained by the service provider. The user accesses the home page via the Web and uses it to select, design, customize, and purchase their new home.

Abstract: A method of determining the dosage of dust control agents applied to coal is disclosed. The method comprises the steps of: (1) treating the coal, with a small amount of a dust control agent containing a compatible fluorescent dye; (2) extracting the treated coal with a polar solvent for the freeze-release agent and determining the fluorescence of such extract; (3) extracting a similar treated coal sample to which a known amount of the dust control agent has been further added and determining the fluorescence of this extract; (4) setting up a proportionality between the fluorescence values of extracts (2) and (3) with the corresponding dosages of dust control agents and solving for the unknown dosage originally applied to the coal.
