LIMB Demonstration Project Extension

Description: The basic goal of the Limestone Injection Multistage Burner (LIMB) demonstration is to extend LIMB technology development to a full- scale application on a representative wall-fired utility boiler. The successful retrofit of LIMB to an existing boiler is expected to demonstrate that (a) reductions of 50 percent or greater in SO{sub x} and NO{sub x} emissions can be achieved at a fraction of the cost of add-on FGD systems, (b) boiler reliability, operability, and steam production can be maintain… more

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

A 12-MW-scale pilot study of in-duct scrubbing (IDS) using a rotary atomizer

Description: A low-cost, moderate-removal efficiency, flue gas desulfurization (FGD) technology was selected by the US Department of Energy for pilot demonstration in its Acid Rain Precursor Control Technology Initiative. The process, identified as In-Duct Scrubbing (IDS), applies rotary atomizer techniques developed for lime-based spray dryer FGD while utilizing existing flue gas ductwork and particulate collectors. IDS technology is anticipated to result in a dry desulfurization process with a moderate re… more

Nitrogen oxide abatement by distributed fuel addition

Description: A screening study was performed on a laboratory scale downfired combustor to determine the effect of various variables on the effectiveness of the reburning process as a technique for NO{sub X} abatement. The objective was to define optimum conditions under which reburning can be used and to be able to compare the reburning performance of our combustor to those reported by others. For this purpose, a statistically designed parametric investigation was conducted to determine how a set of control… more

An investigation to define the physical/chemical constraints which limit NO sub x emission reduction achievable by reburning

Description: Reburning is a combustion modification technique which removes NO{sub x} from combustion products by using fuel as a reducing agent. Previous studies have shown that natural gas is more effective than coal as a reburning fuel Objectives of this program are to define the chemical and physical constraints which prevent the attainment of 80% NO{sub x} reduction with reburning and to test improved configurations for reburning as an advanced NO{sub x} control technique for coal-fired boilers. Bench … more

The kinetics of sulfation of calcium oxide

Description: Studies of the sulfation rate behavior show an initial fast rate followed by a rate decrease. This behavior has generally been interpreted as product layer diffusion limitations taking over after an initial kinetic rate regime. Many investigators tried to model this observed rate change. As pore diffusion was a limiting phenomenon in most of the experiments, authors have used several pore models to described this complication, more or less successfully. Product layer diffusivity has been assume… more

The kinetics of sulfation of calcium oxide

Description: Studies of the sulfation rate behavior show an initial fast rate followed by a rate decrease. It is generally agreed that product layer diffusion limitations are the explanation for this behavior. Many investigators tried to model this observed rate change, more or less successfully. No agreement has been reached, however, as to the value of the produce layer diffusivity. Hence, in this work we want to investigate the mechanism of this process. In addition to understanding the initial kinetics,… more

Nitrogen oxide abatement by distributed fuel addition

Description: Experiments were conducted to investigate the processes that influence the destruction of NO in the fuel rich stage of the reburning process. The objective is to gain a better understanding of the mechanisms that control the fate of coal nitrogen in the fuel rich zone of a combustion process. Time resolved profiles of temperature, major (CO{sub 2}, CO, H{sub 2}O, O{sub 2}, H{sub 2} and N{sub 2}), nitrogenous (NO, HCN and NH{sub 3}) and hydrocarbon (CH{sub 4} and C{sub 2}H{sub 2}) species were o… more

Electro-catalytic Reduction of Nitrogen Oxides

Description: Nitrogen oxides have been linked to a broad range of air pollution problems including acid rain and the atmospheric production of photochemical ozone. Over twenty million tons of nitrogen oxides are emitted into the atmosphere each year as a result of the high temperature combustion of fossil fuels. Efforts to control nitrogen oxides emissions have lagged because of the generally low discharge concentrations of nitrogen oxides in combustion exhaust and because nitrogen oxides are more difficult… more
