进行沼气经济效益评价时,炉灶实际利用的热效率是其重要因素之一。通常所说沼气灶的热效率都是在实验室内特定的条件下测试的,其数值比实际利用时的热效率要高,因此,有必要测试实际利用的热效率。为进一步说明沼气的经济效益,还需将沼气灶与柴灶的利用热效率进行比较。要做到这点,就必须使其具有可比条件。这样才能获得比较科学的依据和结论。这就是进行两种炉灶实际利用热效率测试的主要目的。一、可比条件的确定为了比较沼气灶与柴灶的热效率,须具备一定的可比条件。通过实地测试,我们认为当
When assessing the economic benefits of biogas, the actual utilization of thermal efficiency of the stove is one of the important factors. The thermal efficiency of biogas stoves is usually measured under specific conditions in the laboratory. The values are higher than the actual thermal efficiency. Therefore, it is necessary to test the actual thermal efficiency. In order to further explain the economic benefits of biogas, the utilization efficiency of biogas stoves and firewood stoves needs to be compared. To do this, it must be made comparable. In order to get more scientific basis and conclusions. This is the main purpose of conducting the actual utilization of the thermal efficiency test for both stoves. First, the determination of comparable conditions In order to compare the thermal efficiency of gas stoves and firewood, must have certain conditions. Through the field test, we think when
