Air accumulation in the condenser owing to insufficient output of air extractor can increase the terminaltemperaturedifference and the air pressure component.
The results indicated:decreasing in heater terminaltemperaturedifference could improve unit economy. Whereas heater stopping or leakage would have disadvantage on economy.
结果表明加热器端差减少 ，机组经济性提高 ，而加热器停用或泄漏都将对机组经济性产生不利影响。
