Exergy analysis of a steam power plant: a case study in Iran
In the last decades, exergy analysis, based on the second law of thermodynamics was a method that substituted the energy analysis in studying thermodynamic systems. In this paper, the cycle of a power plant and its details, with two kinds of fuels, natural gas and diesel, have been analysed at its maximum load and the two factors, losses and exergy efficiency, which are the basic factors used to ...

Techno-economic evaluation of revamping of coal-fired power plants in India
A techno-economic feasibility study has been conducted to investigate the revamping of two 32 MWe Pulverised-Coal (PC) boilers with a number of firing options. The options investigated were: (1) conventional PC revamping, (2) replacement with a new PC boiler, (3) PC to Circulating Fluidised Bed (CFB) revamping, (4) replacement with a new CFB boiler, and (5) Bubbling Fluidised Bed (BFB) revamping. ...

Design of boilers with catalytic fluidised bed and their connection to heat supply system
The new advantage of catalytic boiler consisting of the location of heat source near the consumer is described. It imposes some restrictions on the design of such a boiler, which is based on the zonal arrangement approach. The details of such design of boilers with catalytic fluidised bed intended for different purposes (water heating, steam generation, steam superheating) are considered and, in ...

Catalytic combustion of fuels and existing ways for its implementation
The new technology of flameless high-temperature combustion of fuel on the basis of catalytic method has the advantages consisting of the ecological cleanliess of process, the growth of volume thermal stress of furnace space and the reduction of specific quantity of metal and boiler cost. Application of catalytic boiler plants allows to bring in the maximum produced heat to the customers. Thus, ...

Coordination of exergy analysis and the MIND method - applied to a pulp and board mill
The MIND (Method for analysis of INDustrial energy systems) method has been developed for cost optimisation of industrial energy systems, mainly with regard to quantities of energy. Exergy analysis reveals losses, efficiencies and possible improvements. These methods can be combined in order to improve industrial energy systems. In this paper, a Swedish pulp and board mill is used as a case ...

Improving energy use efficiency in Nigeria's industrial sector: a case study of a beverage plant
Industrial energy is a major component of the total energy use in a nation. However, energy is not without a cost in its production, availability, use and even its environmental impact on society. In addition, most of the energy resources are depletable, thereby necessitating their sustainable use through energy efficiency improvement programs. In this investigation, an attempt was made to study ...
