What causes the stator coil of a waste thermal energy generator to explode?

Introduction What is the reason why the stator coil of the waste heat generator explodes? You may have done something wrong. Depending on steam pressure and temperature: medium and low voltage power plants (3.92 MPa, 450 degrees). ,

What causes the stator coil of a waste thermal energy generator to explode?

You may have been wrong. The method is divided into steam pressure and temperature as follows: medium and low pressure power plant (3.92 MPa, 450 degrees), high pressure power plant (9.9 MPa, 540 degrees), ultra-pressure. high pressure power plant (13.83 MPa, 540 degrees), subcritical pressure power plant (16.77 MPa, 540 degrees), supercritical pressure power plant (22.11 MPa, 550 degrees);

According to the prime mover: condensing steam turbine power plants, gas turbine power plants, internal combustion engine power plants, steam-gas turbine power plants, etc. depending on the energy produced, condensing power plants (generating only electricity), thermal power plants (generating and heating);

According to the installed capacity of the plants: Small capacity plants (less than 100 MW), medium capacity power plants (100-250 MW), clarge and medium capacity power plants (250-1,000 MW), large capacity power plants (above 1,000 MW); (1) Steam and water systems: thermal power plants The steam-water system is composed of boilers, steam turbines, condensers, high and low pressure heaters, condensate and feed water pumps. water pumps, etc. It includes steam-water circulation, chemical water treatment and cooling systems, etc. The water is heated to steam in the boiler, is then heated by the heater and becomes superheated steam, then enters the steam turbine through the main steam pipe. As the steam continues to expand, the steam flowing at high speeds causes the turbine blades to spin and drive the generator. In order to further improve its thermal efficiency, part of the steam which has worked is generally extracted from certain intermediate stages of the turbine.does not use steam to heat drinking water. This feedwater heat recovery cycle is used in large modern steam turbines. Additionally, a reheat cycle is also used in the ultra high pressure unit. The steam that has done some work is extracted from the outlet of the high pressure cylinder of the steam turbine and is sent to the reheat steam. from the boiler for heating then fed into the steam turbine. The intermediate pressure cylinder of the turbine continues to expand and do work, and the steam sent from the intermediate pressure cylinder is sent to the low pressure cylinder to continue working. work. As the steam continues to operate, the pressure and temperature of the steam continue to decrease, and eventually it is discharged into the condenser and is cooled by the cooling water, condensing into water. The condensate water is concentered in the lower part of the condenser and is pumped to the low pressure heater by the condensate water pump and then deoxygenated. The feed water pump sends preheated and deoxygenated water to the high pressure heater. is pumped into the boiler and then superheated. The water has been heated into superheated steam in the device and is sent to the steam turbine to do work, which continues to do work over and over again. The steam and condensate in the steam and water system will inevitably experience phenomena such as dripping, bubbling, dripping and leaking due to the large number of unblocked pipes and the need to pass through many valves and equipment. These phenomena will lead to water loss. To a greater or lesser extent, we therefore have to constantly replenish the system with chemically treated softened water. This make-up water is generally reinjected into the deaerator.

(2) Combustion system

The combustion system is composed of coal transportation, coal crushing, coarse and fine separation, powder discharge , powder feeding, boiler, dust removal, draining, etc. . It is transported from the coal yard by belt conveyor through the electromagnet and the coal crusher, then sent to the coal hopper between the coal bunkers, then enters the coal crusher through the coal feeder to be crushed. The crushed coal passes through the air. The hot air from the preheater beats the pulverized coal to the coarse and fine separator. The coarse and fine separator returns the qualified pulverized coal (unqualified pulverized coal to the coal crusher) and sends it to the powder bin via the pulverizer. The Pulverizer Feeder The pulverized coal is drawn into the burner and sent to the boiler for combustion. The combustion gases undergo a precipelectrostatic iteration to remove dust, then the flue gas is sent to the desulfurization device. The gas desorbed by stone mud spray is sent into the chimney through the suction fan and discharged into the sky.

(3) Power generation system

The power generation system consists of an auxiliary exciter, an exciter disk, an exciter main (emergency exciter), a generator, a transformer, a high-voltage circuit breaker, a booster. It is made up of stations, energy distribution devices, etc. Energy production is generated by the auxiliary exciter (permanent magnet) emitting a high frequency current. The current emitted by the auxiliary exciter is rectified by the exciter disk then sent to the main exciter. Once the main exciter has generated electricity, it passes through. The voltage regulatorand the demagnetization switch and passes through the carbon brush. Sent to the generator rotor, when the generator rotor rotates its stator coil, a current is induced. The strong current is divided into two channels through the generator output, one is sent to. the factory power transformer, and the other is sent to the SF6 high voltage circuit breaker. The SF6 high voltage circuit breaker is sent to the power grid. The largest thermal power plant in China at present: the Zhejiang Beilun Port Power Plant, with an installed capacity of 3 million KW (or 3,000 MW) and five 600,000 KW (600 MW) units.
