Analysis of needs make up water cooling tower RSG-GAS at 30 MW power after revitalization

Due to the condition and age of the RSG-GAS cooling tower, revitalization of the cooling tower has been carried out. The new cooling tower has the same type as the previous type, namely Mechanical induced draft, counter flow, In line, Closed end types. As a result of the replacement or revitalization of the RSG-GAS cooling tower, it is necessary to conduct a study related to the amount of water loss. Water loss in a cooling tower consists of: evaporation loss (We), Drift loss (Wd) and blowdown (Wb). The amount of water loss based on the design is 93.8074 m³/h, the calculation result is 53.1286 m³/h and the observation result is 39.4548 m³/h. The loss of water in the cooling tower needs to be taken into account because it is related to the PA-04 pump's ability to compensate for the water loss. With the PA-04 pump's capacity which has a capacity of 100 m³/h, it is certain that the PA-04 pump is still able to compensate for the loss of water in the cooling tower. (author)
