Thermal Economy Analysis Based on Low Level Heating Transformation of Combined Heat and Power Generation of Wet-cooling Unit
A low energy heating renovation plan is proposed to address the problem of significant heat loss during the use of exhaust steam extraction for unit heating.Low energy heating technology enables the use of exhaust steam for pri-mary heat exchange in the heating network,preheating the return water entering the high-temperature heat source heater,and reducing the temperature difference in the secondary heat exchange of the heating network.Compared with the tradi-tional medium exhaust steam extraction heating mode,after the transformation,the heating steam source was changed from medium pressure cylinder exhaust to exhaust steam,which reduced the average heating temperature of the heat source and significantly reduced the temperature difference between the heating source and the heat exchange in the heating network.
