Abstract: An integrated method of removing alkali metal compounds from sulfur-bearing coal is disclosed. The coal is comminuted (4) and mixed (10) with water (8) to form a slurry (12). In the preferred embodiment, the slurry (12) is comingled with an SO.sub.2 -bearing gas (16) in a transport pipeline (52) to form an acidic slurry which dissolves the alkali compounds out of the coal. The slurry is then separated (22) into a solid portion (24) and a liquid portion (26), the solid portion (24) being combusted (34) to form the SO.sub.2 -bearing gas (16).

Abstract: A continuous process for the combustion of solid fuels in a fluidized bed of solid particles under conditions such that flue gas is essentially free of dust and oxides of sulfur and nitrogen. Fuel is charged as an aqueous slurry and additional water condensed from the flue gas is recycled to the combustion zone. Combustion is promoted both by water vapor and alkali added with fuel slurry, while the alkali serves also to neutralize and remove sulfur in completely oxidized, or sulfate, form. Useful heat is recovered from the hot gases leaving the combustion zone and, in some cases, from the fluidized bed itself. Under the pressure of the system recovery of heat results in condensation of water which serves to scrub dust from the flue gas, slurry product ash and furnish recycle water, which controls reaction temperature as well as promoting the combustion.

Abstract: The invention relates to the transportation and preparation for combustion of coal used as a solid fuel at heat power plants and can find applications in coal-based power generation. The object of the invention is a complex use of energy resources contained in coal, reduction of power consumption for the realization of the process, expansion of solid fuel pipeline transport application in coal-based power generation, increase in the coal pipeline operation safety, and the environment protection. Prior to the transportation via a pipeline, the initial stream of coal is screened into coarse material and fines, the latter being pressed into cylindrical monolithic blocks. Coal is transported via a pipeline filled with aqueous salt solution with a density exceeding that of the transported material, the coarse coal and pressed blocks being loaded into the pipeline alternately. At the power station, the coal delivered in the aqueous salt solution is separated from the liquid carrier, rinsed with water, dried and ground with simultaneous capturing of released methane. The effluents of rinsing are evaporated by heat released at the condensation of the working medium of the power plant thermodynamic cycle. The remaining stripped solution is mixed with liquid medium separated from the coal and returned to the starting point of the process.
