Abstract: Many diseases are related to variations in the genetically specified structure of proteins synthesized by cells. Genetic engineering is now able to identify the structural variations and to introduce new genes to synthesize more healthful proteins, but it is difficult actually to identify the specific protein or chemical variants in bodily fluids and extracts of tissues in order to diagnose diseases and to assess the effects of treatment. This invention provides apparatuses and methods which allow a user to finely discriminate between small variations in the structure, function and levels of specific biochemicals even when admixed with other biochemicals.

Abstract: The present invention is a method for reducing the slagging and fouling of the surfaces of the waterwalls, firebox, superheater, and reheater of the furnace of a coal-fired steam boiler. The process reduces the firebox exit temperature to below the specific ash melting temperature by injecting the following, either alone or in combination, into ports located in the upper section of the firebox: recirculated flue gas from downstream of the electrostatic precipitator, atomized water, or a sorbent water slurry. All of these materials have a lower temperature than the main flue gas or require additional heat for evaporation. Mixing these materials with the main flue gas from the furnace will not affect the coal combustion process, yet will reduce the temperature of any fly ash particles in the main flue gas to below the specific ash fusion temperature, and thus, prevent slagging and fouling within the furnace.
