Gas power generation equipment is generally divided into steam turbine power generation and internal combustion engine power generation. Relatively speaking, the efficiency of internal gas-fired power generation is higher, around 80% or more.
@Green ring internal combustion engine gas generator set, gas power generation is generally divided into biogas power generation, natural gas power generation, straw gas power, coal gas power generation, shale gas power generation, etc. .
For details, please consult the gas generator manufacturer @青环.
What are the factors that affect the coal consumption of steam turbines in thermal power plants?
| From the question, the total electricity production Q =8.4×10 10 kW?h, ∵Q discharge=mq, q=2kW?h/kg, ∴The mass of bituminous coal required for complete combustion: < p>m=
Generator Power p=18.2 million kW=1.82×10 7 kW, Then electricity production per day Q′=pt=1.82× 10 7 kW×24h=4.368× 10 8 kW?h, < p>Suppose the number of days is n, thenn=
The answer is therefore: 4.2×10 7 , 193. |
Thermal power plant More than 95% of domestic coal is transformed into electricity. It is very necessary to analyze the factors that affect coal consumption during the operation of thermal power plants. Factors that affect coal consumption come from: the operation of turbines and boilers. main steam parameters, boiler combustion efficiency, condensing device vacuum, low thermal energy of fuel, etc.
The specific influencing factors and technical descriptions are as follows:
First: the unit load rate and the unit start and stop factors are the factors that determine the coal consumption of the unit. Direct influencing factors include lower unit charge rate, efficiency ofe lower boiler operation, increased thermal efficiency, increased plant power consumption, and increased coal consumption for power generation. For every 10% change in unit load rate, power generation coal consumption will change by 3 to 6 g/(kW·h).
Second: The influence of the main steam parameters (2) The influence of. main vapor pressure.
Third: coal ash content. For every 1% increase in coal ash content, power supply coal consumption increases by 0.03 to 0.04 g/(kW·h
Fifth: Electricity consumptionplant tee Although the plant energy consumption rate does not affect the coal consumption of electricity generation, it is directly related to coal consumption. of the electrical power supply to thermal power stations. The lower the power consumption rate of the plant, the lower the coal consumption of the power supply when the power consumption rate of the plant decreases by 0.5%. )
The operating load rate of the unit and the measurement accuracy of raw coal consumption affect the standard index of coal consumption rate of thermal power plant power supply. The rate of coal consumption for electricity generation is an important economic indicator of thermal energy. plants
