This paper describes a construction and characteristics of a coal-gas-burning high e ciency power plant which emits no carbon dioxide (CO 2 ) into the atmosphere. In the plant, CO 2 gas and superheated steam are used as the main and sub working uid, respectively, of a closed dual uid gas turbine power generation system. It is assumed that a coal gas whose principal compositions are CO, H 2 , CO...

Industrial applications that require steam for their end-use generally utilize boilers are typically oversized, citing operations flexibility. Similarly, gas turbine-based power plants corroborate a turbine system may eventually relieve the usable exhaust into atmosphere. This study explores economic and technical feasibility of topping cycle combined heat (CHP) system. It does so by leveraging...

In this paper a comprehensive model of a fossil fueled power plant (FFPP) is developed in order to evaluate the performance of a newly designed turbine follower controller. Considering the drawbacks of previous works, an overall model is developed to minimize the error between each subsystem model output and the experimental data obtained at the actual power plant. The developed model is organi...

A method for purifying the gas-air mixture of a gas turbine unit and waste-heat boiler is considered [1-3]. This work describes principle gas-turbine plant operation using catalytic afterburner, with help which more complete process carbon dioxide nitrogenous compounds release occurs. Also, as result exhaust deeper cleaning process, there decrease in emissions within maximum admissible concentr...

-The integration of Soft Computing techniques in traditional real-time systems is a promising approach to cope with the growing complexity of real-world applications. A power station is a complicated multivariable controlled plant, which consists of boiler, turbine, generator, power network and loads. The demands being placed on Control & Instrumentation engineers include economic optimization,...

the present paper is aimed at describing a “closed cycle” power plant schematic (soft, solar oxygen fuel turbine) with macroalgae (seaweed) cultivation in a pond, combustion of its organic matter in a fluidized bed boiler of rankine cycle and return of the combustion products to the pond to feed algae. the oxygen used for combustion is released to atmosphere in photosynthesis. as a renewable fu...

This paper is to seek effective scheme of boiler efficiency optimization, it uses Artificial Bee Colony (ABC) algorithm to optimize boiler efficiency based on the model of boiler combustion efficiency. First, an optimization model of boiler efficiency, which takes boiler efficiency function as optimization objective, is set up according to the heat loss of boiler combustion. Moreover, the opera...

In order to improve the utilization rate of industrial waste heat and fine design level power station, this paper constructs mathematical model boiler steam turbine, puts forward optimization method thermal system generation project. By using typical cases, it is proved that there optimal pressure HRSG, which makes maximum, provides a HRSG.

OVERVIEW: Among the international efforts to curb global warming, practical application of CO2 removal technology and improvement of powergeneration efficiency — for reducing CO2 emission from thermal power plants (which will probably remain the prime source of power in future) — will, at the very least, become urgent issues over the next several decades. Accordingly, the Hitachi Group is aimin...

The backstepping technique was used in order to synthesise a non-linear control law for the non-linear model of the power plant station. The non-linearities in the model are related to steam flow through the super-heater and action of turbine valves. The time constant of the boiler is considered as an unknown parameter. Its value has to be adapted. The backstepping procedure presents a straight...
