What is the amount of steam generated by the waste heat from the water in the smoke cylinder liner of gas internal combustion generator sets?
Thread Content
The exhaust gas temperature of gas internal combustion generator sets is around 500 degrees, while the water temperature in the cylinder liners is around 90 degrees. If this waste heat is used to feed a waste heat boiler, how much steam can a 1 MW internal combustion generator set produce? I can’t do the calculations. Could you explain in detail exactly how to do them?
The idea is good, but it’s difficult to put into use!
Internal combustion engines are thermoelectrically balanced units; they can make use of the heat from exhaust gases, with the ratio between heat and electricity being approximately 1:1. Assuming an efficiency of 0.8, the amount of steam generated is 800 KW, which is roughly 1.1 tons of steam
Why can’t the cylinder liner water be utilized? It can be used to preheat the feed water
The design institute calculated only 0.7 tons. What’s the reason?

It depends specifically on the proportion of flue gas volume in the overall heat balance
I’ve seen that many designs make use of the low-temperature heat from exhaust gases, such as condensing boilers and economizers; I’d like to know how to calculate things in this regard. What temperature for flue gas is appropriate to ensure economic efficiency?
