Problems solved by technology

The lack of air is under pressure (generally not less than 0.1MPa), and this part of the compressed air has undergone a series of treatments such as oil removal, dust removal and dehumidification, so that the exhaust air is discharged in vain, resulting in a waste of energy

Abstract

The invention provides an ash storage gasification system and a control method thereof. The ash storage gasification system comprises a dust remover, ash storage, a first air storage device, a heater,an air supply device for supplying compressed air and an ash storage device for receiving fly ash. The air supply device, the ash storage device and the dust remover sequentially communicate with each other, an ash discharge port of the dust remover is in communication with the ash storage, an air exhaust port of the dust remover and the air supply device communicate with an air inlet of the first air storage device to introduce the compressed air into the first air storage device, and an air outlet of the first air storage device is provided with the heater; and the heater is in communication with the ash storage through a first pipe. The ash storage gasification system can recover exhaust air under pressure and utilizes the exhaust gas, energy waste caused by the fact that the exhaust gas is directly discharged is avoided, the system structure is effectively simplified, and the investment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an ash storage gasification system and a control method thereof. Background technique [0002] Coal-fired thermal power generation is the most important form of power generation in my country at present. The thermal power plant converts the chemical energy of coal combustion into thermal energy in the boiler, which is absorbed by water and steam. The steam does work in the steam turbine to convert it into mechanical energy. The steam turbine drives the generator rotor. Rotation converts mechanical energy into electrical energy and delivers it to millions of households. Pneumatic ash conveying system is used in thermal power plants. This system collects the fly ash (fly ash) in the boiler economizer and the first ash hopper of the electrostatic precipitator, so that the fly ash is fluidized in the warehouse pump and Evenly enter the ash conveying pipeline. Fly ash ha...
