The quasi_isothermal method used in modulated differential thermal analysis (MDTA) for heat capacity measurement is reviewed.With the aid of heat transfer law and the MDTA model,authors found that a heat capacity obtained by the quasi_isothermal method was actually an average value within measured temperature intervals.The higher the modulated amplitude and frequency,the smoother the heat capacity curve is.In case that the sample heat capacity remains approximately constant within the measured temperature range,the...

The quasi_isothermal method used in modulated differential thermal analysis (MDTA) for heat capacity measurement is reviewed.With the aid of heat transfer law and the MDTA model,authors found that a heat capacity obtained by the quasi_isothermal method was actually an average value within measured temperature intervals.The higher the modulated amplitude and frequency,the smoother the heat capacity curve is.In case that the sample heat capacity remains approximately constant within the measured temperature range,the quasi_isothermal method is preferable.On the contrary,if the sample heat capacity apparently varies with temperature within the measured temperature range,the traditional DTA method for heat capacity measurement is recommended.

对用调制差热分析(MDTA)准恒温法测样品热容量的情形进行了讨论。通过结合最基本的热传导定律和MDTA模型,指出了目前国际上测量样品热容量的准恒温法只能得到在所测温度范围内的物质热容量平均值,调制温度的幅度越大或调制频率越高,所得到的热容量数据越平滑。在所测温度范围内样品热容量基本不变时,用MDTA准恒温法较好;但当样品热容量在所测温度范围内有明显变化时,用传统差热分析法(DTA)更好一些。

By analyzing the heat exchange between the flow of pulverized coal that enters the furnace and the hot gas within the furnace, it has been discovered that the factor that restricts stable combustion in boilers at low load is the inherent property of gas temperature around the burner, by which it will drop reducing load. For the purpose of changing this unfavorable property, the author juts forth a zero dimension model for effecting quasi isothermal combustion, based on the concept of exchangeable heat insulation...

By analyzing the heat exchange between the flow of pulverized coal that enters the furnace and the hot gas within the furnace, it has been discovered that the factor that restricts stable combustion in boilers at low load is the inherent property of gas temperature around the burner, by which it will drop reducing load. For the purpose of changing this unfavorable property, the author juts forth a zero dimension model for effecting quasi isothermal combustion, based on the concept of exchangeable heat insulation boards adjustable within the furnace and has calculated the effect, on the furnace's gas exit temperature, at various loads, of shafting the adjustable heat insulation boards. Some hot state test data of quasi isothermal combustion with adjustable heat insulation boards are presented as well. Figs 5 and refs 5

通过分析入炉煤粉气流与炉内高温烟气间的换热方式 ,找出了锅炉低负荷稳燃的制约因素是燃烧器附近区域烟气温度水平随锅炉负荷降低而降低这一固有特性。为改变这种不良烟温特性 ,作者提出了基于炉内活动可调隔热板的准恒温燃烧概念及实现准恒温燃烧的零维模型 ,并据此计算了活动可调隔热板与负荷变化时对炉膛出口烟温的影响 ;并给出了基于可调隔热板的准恒温燃烧的热态试验部分结果。图 5参 5

On the basis of reviewing the unsatisfactory aspects of currently applied pulverized coal combustion technologies, a new concept of quasi-constant temperature combustion, which is based on movable heat-insulate layer, is first put forward for pulverized coal. Then the structure and working theory of the movable multilayer heat-insulate layer installed on furnace waterwall and can move up and down during operation so as to maintain the flue gas temperature quasi-constant in the space near burner, is introduced...

On the basis of reviewing the unsatisfactory aspects of currently applied pulverized coal combustion technologies, a new concept of quasi-constant temperature combustion, which is based on movable heat-insulate layer, is first put forward for pulverized coal. Then the structure and working theory of the movable multilayer heat-insulate layer installed on furnace waterwall and can move up and down during operation so as to maintain the flue gas temperature quasi-constant in the space near burner, is introduced in detail. Finally, relevant calculation and analysis is made and it shows that movable heat-insulate refractory layer based quasi-constant temperature combustion is promising and it can greatly improve overall performance of PC boiler.
