Rapid sulfur capture studies at high temperatures

Description: Determine conditions that would reproduce optimum sulfur capture ( super-equilibrium'') behavior. No attempt was made to extract kinetic data for calcination or sulfur capture, as might be done in a comprehensive study of sorbent behavior. While some interesting anomalies are present in the calcination data and in the limited surface area data, no attempt was made to pursue those issues. Since little sulfur capture was observed at operating conditions where super-equilibrium'' might be expected… more

Characterizing fluidized bed behavior by decomposition of chaotic phase space trajectories

Description: Recent applications of chaotic time series analysis to gas fluidized beds have demonstrated that substantial information about fluidization conditions within the. bed can be extracted from voidage and pressure drop data. In this paper, a technique is presented to characterize fluidized bed behavior based on the crossings of the phase space trajectory through the principal component planes. Starting with either pressure drop or void fraction versus time data, time series embedding and principal … more

Premixed burner studies of NO{sub x} formation and control

Description: With the enactment of the Clean Air Act Amendments of 1990, there is now additional incentive for the development of gas turbine systems with very low NO{sub x} emissions characteristics. Further, the development of low NO{sub x} burners that are capable of utilizing low-heating-value gases derived from coal based systems is an essential component for a number of fossil energy technologies including IGCC and second-generation PFBC. However, the chemistry associated with NO{sub x} formation is c… more

Aerovalve Pulse Combustion: Technical Note

Description: The authors present a mathematical model and an experimental investigation of aerodynamically valved pulse combustion. The model uses a control-volume approach to solve conservation laws in several regions of a pulse combustor. Mixing between the fresh charge and combustion products is modeled as a two-step process, with the mixing occurring slowly for a specified eddy time during each cycle, and then changing to a higher rate. Results of model simulations demonstrate that eddy time plays a sig… more

Pressure-gain combustion

Description: Pulse combustion has been proposed for gas turbine applications in many early articles and more recently has been demonstrated to produce so-called ``pressure-gain`` in a small gas turbine. The basic concept is that the oscillatory combustion occurs as a constant-volume process, producing a gain in the stagnation pressure of air flowing through the combustor, rather than the pressure loss associated with conventional, steady combustion. If properly utilized, this pressure-gain could enhance sim… more

Greater Green River basin well-site selection

Description: Recent estimates of the natural gas resources of Cretaceous low-permeability reservoirs of the Greater Green River basin indicate that as much as 5000 trillion cubic feet (Tcf) of gas may be in place (Law and others 1989). Of this total, Law and others (1989) attributed approximately 80 percent to the Upper Cretaceous Mesaverde Group and Lewis Shale. Unfortunately, present economic conditions render the drilling of many vertical wells unprofitable. Consequently, a three-well demonstration progr… more

Interpretation of pilot-scale, fluidized bed behavior using chaotic time series analysis

Description: In this paper, we apply conventional and chaotic time series analyses to the interpretation of pressure-drop measurements from a 250 kW, pilot-scale, bubbling fluidized bed combustor. Our results demonstrate that such analyses can be useful for discriminating different types of fluidization in a practical combustor and offer a basis for improving fluidized bed monitoring and control. A new comparative index that reflects the multivariate structure in pressure-drop measurements is proposed for d… more
