5.AN IMPROVEMENT ON CALCULATING METHOD OF WORKING PRESSURE DIFFERENCE IN NATURAL CYCLE TWO-PIPE MCT-WATER HEATING SYSTEM
7.At the end, the high voltage withstand test is made, and the working-pressure of the lift is measured.
8.On the bridge main engine instrument board, there is main engine cooling water thermometer, lub oil pressure gauge, main engine revolution indicator, main engine emergency shutdown pushbutton, and there is audible and visual alarm device for main engine lub oil low pressure, cooling water high temperature , gear box lub oil low working pressure.
9.In order to study the influence of pressure on coal gasification, a pressurized circulation fluidized bed gasification pilot in a pressure shell of 1.3 m in diameter and 4 m in height with the highest working pressure up to 2.5 MPa is made. Some cold tests are carried out and gasification tests will be made.
