Classification of Boilers The boilers may be classified mainly as follows : (1) Depending upon the relative position of water and flue gases : (a) Smoke tube or fire tube boilers : In these type of boilers the hot gases or the flue gases from the furnace are passed through the tubes surrounded by the … Read more
Rankine Cycle with Reheat Figure A Figure B One way of improving the efficiency of the Rankine cycle is by reheating the steam in between the stages of expansion as shown in schematic, (T-S) and (h-S) diagrams in Figure (a), (b) and (c) respectively. In this cycle, the steam is extracted after expansion in high … Read more
Advantages of Rankine Cycle over Carnot Cycle Following are the advantages of Rankine cycle over Carnot cycle : A steam power plant on Carnot cycle cannot be practically built due to its inherent difficulties in carrying out the process of condensation and compression. While, a practical steam power plant on Rankine cycle can be easily … Read more
Present Status of Power Generation in India Economic growth in India depends on the power sector. The electric energy demands in the last two decades have increased at enormous space. In 1947, the total power generation was only 1360 MW. The present power generation status as planned is as follows : Table A: Indian generation … Read more
Present Installed Capacity and Sectorwise Allocation Total installed capacity in India is 1,57,000 MW from various energy sources. The sources wise contribution to electrical power generation is : Coal = 63% Oil = 4.6% Gas = 11.5% Nuclear = 2.8% Renewable 12.8% (Hydro = 11.9%, Wind 0.6% and Biomass = 0.3%)
Global Energy Consumption As against the available sources of energy, the energy consumption is showing a much faster growth rate. These are given in the succeeding sections sector wise. The global primary energy consumption at present was equivalent to 9741 million tonnes of oil equivalent (Mtoe). Table gives the figures of world consumption of energy … Read more

Site Located near load centre having cheap and large land, water supply, transportation facilities etc. Located where large … Read more
Advantages and Disadvantages of MHD System Advantages of MHD System : It converts heat energy directly into electrical energy at higher conversion efficiency compared to convectional type of power plants. These systems are reliable and produces power pollution free. Large amount of power is generated with small sized plants as compared to conventional power plants . It … Read more
Types of MHD Power Plants The operation of MHD systems are broadly divided as follows : Open cycle system Closed cycle system 1. Open Cycle MHD System : Figure A shows an open cycle MHD power plant. The system uses an MHD generator in conjunction with conventional steam power plant. The fuel used may be … Read more
Fuels and Material Used In MHD Plants MHD plants can use conventional fuels like oil, coal, natural gas, kerosene, benzene, toluene. It can also use nuclear energy or any other form which can produce high temperature. The materials used in construction of MHD plants must have temperature resistance. Also, the high temperatures combined with alkaline … Read more
