Pulverized Combustion

Though the majority of research on fly ash has proved its worth as a construction material, the utility of bottom ash is yet questionable due to its generation during the pulverized combustion process. The bottom ash produced during the fluidized bed combustion (FBC) process is attracting more attention due to the novelty of coal combustion technology. But, to establish its suitability as construction material, it is necessary to characterize it thoroughly with respect to the geotechnical as well as mineralogical points of view. For fulfilling these objectives, the present study mainly aims at characterizing the FBC bottom ash and its comparison with pulverized coal combustion (PCC) bottom ash, collected from the same origin of coal. Suitability of FBC bottom ash as a dike filter material in contrast to PCC bottom ash in replacing traditional filter material such as sand was also studied. The suitability criteria for utilization of both bottom ash and river sand as filter material on pond ash as a base material were evaluated, and both river sand and FBC bottom ash were found to be satisfactory. The study shows that FBC bottom ash is a better geo-material than PCC bottom ash, and it could be highly recommended as an alternative suitable filter material for constructing ash dikes in place of conventional sand.

So2 Emissions

New York University (NYU), under a Department of Energy (DOE) contract, has designed and constructed a sub-pilot scale Pressurized Fluidized-Bed Combustor (PFBC) Facility at the Antonio Ferri Laboratories, Westbury, Long Island. The basic feature of this experimental research facility is a well-instrumented, 780 mm diameter coal combustor capable of operating up to 1010 kPa and provided with a liberal number of ports, making it a versatile unit for study of fundamental in-bed phenomena. Further, the overall design features make it a flexible facility for solving a variety of industrial research problems. The main objectives of the facility are three-fold: (1) to develop fundamental data and correlations in the fluid mechanics and combustion process in PFBC; (2) to perform research in important areas of pressurized fluidized bed-combustion, like low-grade fuel combustion under pressure; and (3) to provide the PFBC community with an experimental research tool for basic and applied research in order to accelerate the commercialization of this technology. The facility started its shakedown tests utilizing bituminous coal in September, 1982. Subsequently, experimental research was, and is, being conducted in the combustion of North Dakota lignite at 710 k Pa. The results presented in this paper describe the research recently obtained with tests conducted at pressurized conditions (710 k Pa)utilizing North Dakota lignite. Preliminary results indicate that the agglomeration process may be suppressed due to the higher pressure. In addition, the research indicates than an inert bed material could be used in the combustion process for controlling SO2 emissions. This is attributed to the alkali compounds present within the ash of the lignite. The research also indicates that SO2 emissions could be controlled by varying the excess air.

Near Term

Fluidized bed combustion is capable of utilizing a wider variety of fuels (including solid wastes) than is any other combustion process. Thus, it has the potential for wide application in systems for recovering energy from solid wastes in industry, commercial sites, institutions, forestry, and agriculture to produce electric power, process steam, process heat, and space heating. Three fluidized bed combustion concepts are identified for near-term application: atmospheric fluidized bed boiler, exhaust-heated gas turbine or combined cycle, and closed-cycle gas turbine.

Agricultural wastes as Biomass contains low carbon, high hydrogen, high oxygen and a lower amount of sulfur. Coals contain higher amounts of carbon, lower amounts of hydrogen, lower oxygen and higher amounts of sulfur. With the use of lignite and biomass mixture as fuel will provide less CO2 and SO2 emissions and a more economical mixture will be obtained. Considering these emissions, fluidized bed combustion systems are recommended in the literature for the combustion of lignite and biomass. In this study, rice husks, corn cobs, walnut shells, sunflower shells, olive cake and woodchips were used as agricultural waste. 10 different lignite extracted from Turkey were used as fuel. It has been assumed that the combustion process was carried out by taking the biomass rate of 10%, 30% and 50%. When burning of 1 kg of lignite and biomass mixture, the highest CO2 emission occurs from 10% woodchips - 90% Kütahya - Ömerler (washed) mixture as 2.938 kg and the highest SO2 emission obtained from 10% olive cake - 90% Kütahya Seyitömer-Ayvalı lignite mixture as 0.061 kg. The highest H2O emission was obtained by mixing 50% woodchips - 50% Manisa-Kısrakdere lignite as 0.563 kg.
