Abstract
In work results of calculations of main units of steam -turbine mini-thermal power plants of low power: 6, 11,4, 12, 20 and 25 MW intended for work in the autonomous mode are presented. On the basis of material, thermal and the exergy balances efficiency indicators – the exergy efficiency and specific expenses of fuel are defined. With a greatest exergy efficiency at the level of 33% have MW blocks 6, 20 and 25 that testifies to a possibility of effective combination of the boiler and turbine equipment of this power and also completing of technological schemes of mini-thermal power plant on the basis of the released drying and mill equipment, boilers and turbines of low power.
