On Sunday, June 3rd, we offer Short Courses on a wide variety of topics important to the energy community. Participation is optional; is included in the registration fee; and open to all conference registrants.
9:00 – 11:00 a.m. – Combustion 101
Alan Paschedag, Covanta, Inc., and J.J. Letcavits, American Electric Power
All you need to know about mixing fuel and air to create combustion. The various conditions that must be controlled such that combustion is both efficient and low in pollutants will be discussed. With this basic understanding of the combustion process, the process of burner tuning will be better understood. A basic approach to burner tuning will also be covered.
11:15 a.m. – 1:15 p.m. –Practical Optimization of the Coal Supply Chain
G.H. Luttrell, Virginia Tech; and J. Bethell, Marshall Miller and Associates
Coal processing, handling and storage facilities play an important role in determining the overall economic viability of the fuel supply chain for coal-fired power stations. Optimization of these important facilities has traditionally been performed using search-engines that require large amounts of information such as coal quality data, production statistics and site costing models.
While this generic approach is technically correct, many operations have been overwhelmed by the large amount of real-time data that is required to properly implement such an optimization strategy. In light of this problem, a new optimization methodology has been developed that assigns unit values to each particle passing through the coal supply chain based on market sales contracts. This presentation describes the working features of this alternative optimization protocol and provides case studies illustrating the large economic value of well-designed coal processing and handling systems on coal-based fuel supply systems.
1:30 p.m. – 3:30 p.m. –Combustion Fundamentals
Prof. Ashwani K, Gupta, University of Maryland
This Short Course will cover fundamental aspects of combustion, including fuels and their fundamental properties, stoichiometric balances, adiabatic flame temperature calculations, flame stability and pollutants formation and mitigation. No prior knowledge on the subject will be assumed so that this tutorial will be very fitting to students and users of combustion devices in industry.
3:45 p.m. – 5:45 p.m. –Advanced Biomass Pellet Characteristics for Utility Scale Co-firing and Conversion Programs
Les Marshall, Ontario Power Generation Canada
The utility industry has made significant gains with decarbonising coal-fired power generation through the use of biomass co-firing and more recently via complete coal to biomass fuel conversions. Conversion projects especially have historically required high capital expenditures, limiting the adoption of this route in many jurisdictions. Recent developments in the field of 2nd generation solid biomass fuels (advanced biomass) have enabled another potential pathway for utility-scale biomass use. These new “advanced biomass” pellets are produced with a range of thermal upgrading techniques to modify their physical characteristics such that they can form the basis of a low capital cost approach for a co-firing or conversion project. The characteristics of both traditional white wood pellets and the new advanced biomass pellets will be discussed from an end user point of view. The results of fuel evaluations will be confirmed with practical full scale operating experience.
