摘要： This invention pertains to a fertilizer and a process for producing the same which incorporates flyash, which is a by-product from the coal fired utility industry, with an organic fertilizing component comprising manure. The flyash and manure are mixed with the resulting mixture compressed by passing the mixture through a roller press thereby forming a sheet and then fracturing the sheet into chips or other particulate form. The water content of the mixture is controlled in an effort to produce particulates having high dry strength.

摘要： This invention relates to an improved process for producing gypsum calcium sulfate dihydrate flakes from powdered gypsum calcium sulfate dihydrate obtained from the desulfurization of flue gas by the wet limestone process. The flakes have sufficient size and strength such that the gypsum calcium sulfate dihydrate can be handled and processed in conventional equipment commonly used by wallboard manufacturers and others in the construction industry, The intermediate calcium sulfate dihydrate from the desulfurization process is dewatered to about 5 to 12% by weight and then compressed into a thin sheet under a compaction or compression load of 4 tons force to 15 tons force per linear inch of sheet width. A linear speed of from 0.5 to 2.5 feet per second is maintained during compaction providing a compaction residence time of from about 0.2 to 1.2 seconds. An elevated temperature is maintained during the compaction process to enhance the reformation of the crystal size and shape of the gypsum calcium sulfate dihydrate. The combination of pressure and temperature on the moist gypsum calcium sulfate dihydrate alters the physical characteristics of the gypsum calcium sulfate dihydrate, thereby resulting a sheet which breaks into hard flakes on exit from the compaction zone.
摘要翻译：本发明涉及从通过湿法石灰石法从烟道气脱硫获得的粉状石膏硫酸钙二水合物制备石膏硫酸钙二水合物片的改进方法。薄片具有足够的尺寸和强度，使得石膏硫酸钙二水合物可以在建筑行业的墙板制造商和其他通常使用的常规设备中处理和加工。来自脱硫过程的中间体硫酸钙二水合物脱水至约5至12 重量％，然后在4吨力的压实或压缩载荷下压制成薄片，每片线宽度为15吨力。在压实期间维持0.5至2.5英尺每秒的线速度，提供约0.2至1.2秒的压实停留时间。在压实过程中保持升高的温度，以增强石膏硫酸钙二水合物的晶体尺寸和形状的改变。压力和温度对潮湿石膏硫酸钙二水合物的组合改变了石膏硫酸钙二水合物的物理特性，从而导致在压实区域出口时破碎成硬片的片材。

摘要： Combustion of petroleum coke using air to carry the fuel into a combustion zone and to provide a source of oxidant. Enhanced combution utilizes oxygen introduced into or proximate primary, secondary, tertiary, quaternary, or over-fire air to effect primary combustion of the fuel. Petroleum coke fuel in an oxygen supported air-petroleum coke combustion process can be used to re-power a utility boiler.
