A non-linear model has been developed for a gas-fired furnace in which oil is heated. The model is applicable from minimum to maximum heat load of the furnace. The dynamics of the model have been compared to experimental results, which were obtained for a pilot-scale furnace. They are in good agreement. A cascade control with feed-forward action has been compared to single feed-back control. Pr...

The profitability impacts of solvent storage are modeled for new coal and natural gas-fired power plants with amine and ammonia-based post-combustion CCS facing variable electricity prices. With perfect information of future prices, up to 3 hours of solvent storage was valuable due to price volatility at carbon prices up to $40/tonne CO2 and no regenerator undersize. With imperfect information ...

Emission inventories are a fundamental input for atmospheric chemical transport models in order to accurately simulate air pollution and its impacts. In Australia, emission currently not available electricity generators at high temporal spatial resolutions. this study, new resolution inventory Australian power plant emissions has been developed. The from coal- gas-fired plants have estimated us...

A Computational Fluid Dynamics (CFD) modeling study has been conducted to evaluate the application of overfire air (OFA), Fuel Lean Gas Reburn (FLGR), and Selective Non-Catalytic Reduction (SNCR) to reduce NOx emissions from Owensboro Municipal Utilities’ Elmer Smith Station. Smith Station Unit 1 is a nominally rated 150 MWe single-wall cyclone fired boiler with three barrels. FLGR is a NOx con...

Simple design of a rotary valve system is capable of controlling intake and exhaust gases, which will eliminate the need of known complex mechanisms. The cost of material and production, maintenance, and noise level of the system can be further reduced. The new mechanism enables the elimination of the overlapping of valves work that reduces gas leakage. This paper examines theoretically the gas...
