Nitrogen oxide abatement by distributed fuel addition

Description: The performance of the new combustor was tested. Experiments showed that this combustor has superior insulating quality than the previous one. Measured radial concentrations indicated uniform distribution of the primary fuel (coal) inside the fire tube resulting in reasonably flat concentration profiles. However, measured radial concentrations after the addition of the reburn fuel showed uneven distribution of the fuel resulting in parabolic concentration profiles, an indication of insufficient… more

Identification of hazards in non-nuclear power plants: phase II

Description: Electric generating stations can impose on and expose the general public and environment to adverse demands and emissions that may be considered detrimental or degrading. For example, a conventional coal fired plant demands coal as its fuel which, in turn, creates a demand for coal mining and coal transportation systems that may degrade the environment. In addition, the emissions from the coal plant (sulfur dioxide, ash, and other waste products), if not managed and controlled properly, might l… more

The demonstration of an advanced cyclone coal combustor, with internal sulfur, nitrogen, and ash control for the conversion of a 23 MMBtu/hour oil fired boiler to pulverized coal

Description: The project objective was to demonstrate a technology which can be used to retrofit oil/gas designed boilers, and conventional pulverized coal fired boilers to direct coal firing, by using a patented sir cooled coal combustor that is attached in place of oil/gas/coal burners. A significant part of the test effort was devoted to resolving operational issues related to uniform coal feeding, efficient combustion under very fuel rich conditions, maintenance of continuous slag flow and removal from … more

Industrial market for sulfur dioxide emission-control systems. Final report. [Forecasting to 2000]

Description: Under the postulated EIA medium world oil price scenario, in which oil prices are projected to rise at a real rate of 2.2% per year, coal will represent from 78 to 91% of MFBI fuel consumption by the year 2000, up from the present 16%. This increase would occur even in the absence of FUA, because the cost of coal is substantially lower than the cost of oil or gas. Much of this market will develop in the relatively near to intermediate term (before 1990). Annual installations will be much lower … more

Assessment of pulverized-coal-fired combustor performance. Seventh quarterly technical progress report, April 1-June 30, 1982

Description: There are substantial economic incentives to explore the possibility of converting boilers and other industrial processes from natural gas or oil to pulverized-fuel firing; however, such a change can have a considerable impact on the thermal performance of the system, due mainly to: fuel specific adiabatic flame temperatures; different flow and combustion patterns in the furnace; differences in the type and concentration of radiative species, especially particles, in the combustion products; an… more
