Gas-steam combined cycle cogeneration
Energy consumption index calculation method
1 Scope
This standard establishes the general principle of reasonable electric and heat apportionment for gas-steam combined cycle heat and power generation, and specifies the calculation of energy consumption indicators
method.
This standard applies to the calculation of energy consumption indicators for heating conditions of gas-steam combined cycle cogeneration units without supplementary combustion.
Be applicable.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1
Total input heat consumption combinedcycleheatconsumption
The total heat input through fuel combustion in the gas-steam combined cycle during the statistical period.
2.2
Heat consumption for heatsupply
The calories consumed by external heating during the statistical period.
2.3
Heating cost allocation ratio costalocationforheatsupply
During the statistical period, the cost of heating consumption accounted for the proportion of the total cost.
2.4
Combustion chamber exit combustionchamberexhuastexergy
The effective energy of the flue gas output by the combustion chamber during the statistical period.
2.5
Aircompressorexergyconsumption
The effective energy consumed to drive the compressor during the statistical period.
2.6
The waste heat boiler receives exergyacquired by HRSG
The effective energy that enters the waste heat boiler to provide downstream circulation during the statistical period.
2.7
Upstream gasturbineexergyconsumption
The effective energy on the upstream side of the combined cycle (before the gas turbine exhaust vent, except for the compressor) during the statistical period.
2.8
Exergy ratio for the downstream side
During the statistical period, the effective energy on the downstream side of the combined cycle (after the gas turbine exhaust port) accounts for the percentage of the entire cycle.
2.9
Heat supply ratio heatconsumptionfraction
The ratio of the heat consumed by heating to the total heat output of the waste heat boiler during the statistical period.
