Calculation Results

The simplified FEA method was proposed on tubesheet of fixed tubular heat exchanger with bellows expansion joints. Taking the waste heat recovery heat exchanger for example, the entire model and the simplified model were established using ANSYS software, and the calculation results of the key components of the two models were compared. The results show that distribution of TRESCA stress intensity and radial displacement of tubesheet for the simplified model are consistent with those of the whole model, but the stress of the simplified model is slightly larger than that of the entire model, so the result is conservative. It means that the simplified method is feasible. Meanwhile, application research on tubesheet of different kinds of heat exchanger was made using the simplified design method, it provides an efficient FEA method of the tubesheet design for heat exchanger with expansion joints.

Recycle And Reuse

In order to obtain efficiency and economy of a ceramic tunnel kiln’s flue gas heat exchanger, firstly, the exchanger’s sizes and thermal parameters on operative conditions were measured. Secondly, flow field and temperature field in the operative exchanger were numerically simulated by using FLUENT, a computational fluid dynamics soft ware. Finally, on base of the simulation, the exchanger’s efficiency and economy were calculated. The calculation results are listed as the following: (1) Energy savings in per unit time for utilizing the heat exchanger to recycle and reuse the flue gas’s waste heat is 112.2kW. (2) Efficiency of the heat exchanger equals 77%.

Equipment Utilization

The business unit's black tea processing of Perkebunan Nusantara suffered a loss of approximately Rp.60 billion. This is caused by the failure to achieve the quality and quantity of production which has been targeted by the management. Black tea processing factory "Pahit Madu" is required to improve the performance of the production process. To improve the production of black tea starts from improved production equipment through improved equipment utilization. One method ofmeasuring the effectiveness of using an apparatus is Overall EquipmentEffectiveness (OEE). OEE calculation results show that black tea factory "Pahit Madu" for four (4) years under the standard. Means, the effectiveness of utilization of equipment in the factory black tea "Pahit Madu" was still very low. This was shown by the low performance equipment in the milling unit, drying unit and sortation unit. Toimprove the performance of the plant should begin by increasing the Cutting Tearing Curling (CTC) machine in milling stations, machines Fluid Bed Dryer (FBD) and Heat Exchanger (HE) at the drying stations, and Winnower machines at the sortation stations.
