Original cost input unit 31a imports original cost, and it comprises equipment cost and the required installation cost of waste heat recovery compressor is installed.
Fuel slip input unit 31b input fuel slip, this value is the fuel quantity of the minimizing of unit transport amount.When calculating the fuel slip when input fuel slip or by investment recycle program back-up system 30, it is obtained by following formula:
Specific fuel consumption * 100% before fuel slip=(specific fuel consumption after the specific fuel consumption-modification before revising)/modification
Apportionment ratio input unit 31d imports apportionment ratio, and this apportionment ratio is because fuel reduces the ratio of the profit that is produced according to the contract distribution of signing.
Return period, return period was invested in input unit 31e input.
Increase transport volume input unit 31f imports the increase of the transport volume that produces owing to installation waste heat recovery compressor.
Unit transport expense input unit 31g input unit transport expense, this expense is the freight of unit transport amount.
Market for natural gas database 35a has stored the market price of rock gas (combustion gas) at least, for example, and the market price of Pai Lieing in chronological order.
Emission credit market data base 35b has stored CO at least
2The market price of emission credit (greenhouse gas emission license), for example, the market price of Pai Lieing in chronological order.
User's credit database 35c has stored the data of the user's who is converted into numerical value ability to pay.
And the result added up, accumulative frequency is the quantity of return period.
When having kept CO
2The restriction of discharging, and profit is when it being converted to money obtaining, income computing unit 32 multiply by transferable CO from the market price that emission credit market data base 35b extracts emission credit
2The market price of emission credit and apportionment ratio, that is,
