Modeling Techniques

Electrostatic precipitator (ESP) modeling development has reached the point in which internal algorithms completely simulate the operation and particulate collection physics of full-scale units. The modern ESPVI 4.0 series of models by using advanced techniques are able to evaluate changes in a precipitator’s configuration and operation to optimize its performance. The author’s applied these techniques to ESPs’ at the Kashira Power Plant near Moscow, having relatively small specific collector area’s (SCA), whose performance will have to be enhanced to meet emerging standards. Advanced modeling techniques include determining electrode and particle properties, operation below back corona onset, and effects of improved electrodes and electrical conditions. The precipitators with collection efficiencies of 88.4 (without natural gas co-firing) up to 93% (with partial co-firing) are shown to be capable of efficiencies of up to 99% by application of modest changes in configuration and operation. The advanced modeling techniques described in this paper are not only important for Kashira, they are also applicable to other power stations requiring performance optimization.

In this paper two options for H2 production, by means of fossil fuels, are presented and their performances are evaluated when they are integrated with advanced H2/air cycles. In this investigation two different schemes have been analyzed: an advanced combined cycle power plant (CC) and a new advanced mixed cycle power plant (AMC). The two methods for producing H2 are as follows: • partial oxidation of methane; • gasification of coal. These hydrogen production plants require material and energetic integrations with the power section and the best interconnections must be investigated in order to obtain good overall performance. With reference to thermodynamic and economic performance, significant comparisons have been made between the above mentioned reference plants. An efficiency decrease and an increase in the cost of electricity have been obtained when power plants are equipped with a fossil fuel decarbonization section. The main results of the performed investigation are quite variable among the different H2 production technologies here considered: the efficiency decreases in a range of 5.5 percentage points to nearly 10 for the partial oxidation of the natural gas and in a range of 6.2–6.4 percentage points for the coal gasification. The electricity production cost increases in a range of about 33–37% for the first option and in a range of about 24–32% for the second one. The clean use of coal seems to have very good potentiality because, in comparison with natural gas decarbonisation, it allows lower energy penalizations (about 6 percentage points) and lower economic increases (about 24% for the CC).

Plant Data

Coal-based warm power stations are the pioneers in control age in India and are significantly awesome nonlinear structures. The warm introduction data procured from thermal control plant shows that glow rate and evaporator capability is changing consistently and the plant is doubtlessly losing a couple of Megawatts of electric power, and more fuel use as such achieving significantly higher carbon impressions. It is incredibly difficult to examine the rough data recorded step by step during the full power action of the plant in light of the fact that a warm power plant is a staggering structure with an enormous number of parameters. Subsequently there is a prerequisite for nonlinear showing for the power plant execution assessment in order to satisfy the growing needs of money related and operational necessities. The point of this paper is to give a blueprint of a coal-ended power plant, in perspective on real plant data and this fills in as the internal model for estimate of the Heat Rate and Boiler Efficiency. This model of the thermodynamics of a power plant is used to choose the effect of changes in different elements upon the glow rate and evaporator capability utilizing affectability coefficients, which show the heading of progress in the variable that will improve warmth rate and pot adequacy, and thus exhibits the general criticalness of these different components. This information can be used to provide guidance to the plant managers and pros concerning where they should devour their undertakings to improve the glow rate and evaporator viability. Further assortment in these key parameters foreseen by affectability examination helps in extemporization of Heat Rate and Boiler Efficiency.

This paper sets out an assessment of the value and practicality of the construction of fossil fired generating plant designed and built as single units and includes a proposal for the design and layout of a single unit designed to maximize the benefits derived from this concept. The conclusion is that an acceptable design of power plant, based on the construction of single 600 MW units, can be developed for the UK system which could prove to be advantageous in construction time, in capital cost and in running cost. The layout applies equally effectively to large ‘green field’ sites or for replanting existing stations; in addition, the plant can be replicated in detail and thereby reduce design and engineering costs. Finally the layout can also be applied in principle to smaller units for overseas utilities as required by their system developments.
