Source and effect of environmental protection.In addition, the control for the circular flow for passing through working media, it can be ensured that the work of cylinder in the present invention
Make the temperature and flow and the uniformity of traditional fuel engine of media outlet 7 and working medium inlet 6.
The heat conversion of current fuels and energy machine is general (to contain power output/generating transformation efficiency and machinery within 45%
Conversion ratio), this, which means that, is discharged into the fuel heat for having 55% in environment.This technical indicator has maintained decades
Broken through without technical.The heat conversion of the estimated recovery waste heat of this project is more than 5-8% (being fluctuated with seasonal variations), if remaining
Hot driving amount is 45% (more than 20% heat dissipation scatters and disappears) of Fuel Consumption, then is calculated as below：
Embodiment 1：If fuel consumption is 10000kW, its mechanical conversion rate is：
10000*45%=4500kW
Assuming that the waste heat amount reclaimed is fuel 40%, remaining thermal transition amount is：
10000*45%* (5~8) %=225~360kW
The mechanical conversion rate of fuel reaches：
4500+ (225~360)=4725~4860kW
Then increase to 47.25~48.6% equivalent to actual increase total output transformation efficiency, this will be a great skill
Art breaks through, and its economic benefit and environmental benefit all will be immeasurable.
