Abstract

The invention relates to an automation thermal power plant adopting a closed-loop control technology. The automation thermal power plant comprises a central control device, a combustion gas turbine power generating mechanism, a waste gas treatment mechanism and a waste heat recovery mechanism, wherein the combustion gas turbine power generating mechanism, the waste gas treatment mechanism and the waste heat recovery mechanism are sequentially communicated; and the combustion gas turbine power generating mechanism comprises an air inlet pipe. According to the automation thermal power plant adopting the closed-loop control technology, the temperature in the waste heat recovery mechanism is accurately measured through a temperature sensor, the temperature is then fed back to a control valve to form closed-loop control, it is guaranteed that the inlet water speed is accurately controlled, and therefore sufficient absorption of residual heat is achieved; then the residual heat is sufficiently used by the combustion gas turbine power generating mechanism to generate power, so that the using efficiency of the residual heat is improved; in this way, an exhaust damper, a first chimney and a second chimney are matched, so that graded treatment on gas is achieved, the treatment reliability of waste gas impurities is accordingly improved, pollution to the environment is reduced, and the practicability of the device is improved.
