This study presents the thermodynamic model of a heat, power and gas cogeneration system. The energy utilization coefficient μ, which is the ratio of the sum of gas calorific value and heat supplied to the boiler to the low calorific value of coal, is used as a criterion to evaluate the...

The present paper was performed to analyze the pyrolysis process of corn straw. Based on the thermogravimetric analysis, the component of pyrolysis gas of corn straw was tested using the gas chromatograph analyzer. Experimental results showed that, as the reaction temperature increases, the...

A numerical study on the performance of an adjustable ejector was presented. An axial spindle extending into the nozzle was used to change the throat area of the nozzle to make the ejector adjustable. The re-normalization group (RNG) k-epsilon model reconciled better with experimental...
