Area.The leaving water temperature of the first jacket water tube outlet of internal combustion engine 1 is less than the second jacket water pipeline of internal combustion engine 1
The leaving water temperature of outlet, such as, the leaving water temperature of the first jacket water tube outlet is 53 DEG C, the second jacket water pipeline
The leaving water temperature of outlet is 90 DEG C.
In illustrating at one, as a example by Fig. 1, current large combustion engines separate unit can generate electricity more than 9000kW, with 9340 types
As a example by, natural gas burns acting generated energy 9340kW at internal combustion engine, and output energy has following three kinds:
-180m3/ h, the hot water of temperature 53 DEG C；
-53400kg/h, the high-temperature flue gas of 375 DEG C；
-180m3/ h, the hot water of temperature 90 DEG C.
For Optimum utilization high-temperature flue gas and low-temperature water heating, technological process that the novelty that this utility model uses optimizes and old
Some technological processes are essentially different.
The technological process of traditional internal combustion engine cold, heat and electricity triple supply is as follows:
1、180m3/ h, the hot water of temperature 53 DEG C are directly lowered the temperature by cooling tower.
2,53400kg/h, the high-temperature flue gas of 375 DEG C and 180m3/ h, the hot water of temperature 90 DEG C are directly entered fume hot-water type
Lithium bromide chiller freezes.
The shortcoming of traditional internal combustion engine cold, heat and electricity triple supply:
1, exhaust gas temperature higher about 140 DEG C～160 DEG C, cause the energy availability of internal combustion engine less than 80%.
2, cause changing greatly by refrigeration duty because of reason in season, when with refrigeration duty relatively low time, cause more thermal resource to be wasted,
Or system cannot run and shut down.
And the process chart that the large combustion engines cold, heat and electricity triple supply that this utility model provides optimizes system refers to Fig. 1.Its
Main optimization is put following three points:
1、180m3/ h, 53 DEG C of hot water of temperature can enter heat exchanger in the winter time and carry out central heating, it is not necessary to logical during heat supply
Supercooling tower is lowered the temperature.
