... with an additional air bottoming cycle to utilize heat of exhaust gases was used to carry out a technical and economic analysis. The approach used in the study is aimed at solving two types of optimization problems: (1) to determine the maximum net efficiency of the power plant and (2) to adjust the equipment and operating parameters for achieving minimum costs of electricity production. The study shows that the air bottoming cycle provides an increase in the net efficiency up to 44 - 48% and adds ...

The system is based on multi-stage wood biomass gasification. The use of producer gas in the system affects negatively the internal combustion engine performance and, therefore, reduces the efficiency of the ICE-CHP plant. A mathematical model of an internal combustion engine running on low-calorie producer gas was developed using an overview of Russian and foreign manufacturers of reciprocating units, that was made in the research. A thermal ...

For this purpose, mathematical models were developed for individual stages of the process, such as pyrolysis, pyrolysis gas combustion, and semicoke gasification. The effect of controlling parameters on the efficiency of fuel conversion into combustible gases is studied numerically using these models. For the controlling parameter are selected heat inputted into a pyrolysis reactor, the excess of oxidizer during gas combustion, and the wood moisture content....
