In the approach, terminal temperature difference is chosen to reflect the fouling state, Neural network modeling is applied to separate the influences of both the fouling and off-design condition on terminal temperature difference.

In the method,terminal temperature difference is chosen to reflect the fouling state,diagonal recurrent neural network is applied to separate the influences of both the fouling and off-design condition on terminal temperature difference.

The temperature difference at warm end of the No2 14000Nm3/h oxygen producing device was large when it was put into production.

Study on heat transfer temperature difference between non-heated staircase and adjacent heated rooms;

Based Stirling ideal refrigeration cycle,the heat transfer temperature differences in the cold end and heat end of Stirling cooler were dealt with dimensionless method.

With the relationship between the pressure drop and the heat transfer temperature difference in the gas turbine recuperator included,the heat transfer difference can be further recommended as the evaluation criterion instead of the recuperator effectiveness for recuperative gas turbine cycles.

It is very important to analyze the influence of terminal temperature difference on thermal economy of unit under conditions of constant power output.

Based on the matrix method, two mathematical models influenced by each extraction steam pressure loss and terminal temperature difference on thermal economy of unit are established.
