Another reason for water in the equipment may be due to pressure testing of any part of the equipment with water. since without it there would not be any oxygen in the circuit and, therefore, even if autoignition point temperatures were reached in a closed circuit, combustion would not be possible. Testing standards Gate valves open and

of scale formation. For this reason the cooling water outlet temperature is usually maintained at about 78-82°C. Because it is at a higher temperature than the cooling water used for other purposes (known as the LT cooling), the water for cooling the engine is known as the HT (High Temperature) cooling water.
