The hot central plant recycling problem with the energy consumption is large, pollution is serious and its production cost is light. A new energy technology of the gas-generator is introduced. Based on the gas-generator technology, calculation is made on the heating system of hot central plant recycling of thermodynamic; combine with actual production, through the gas-generator plant compare with coal-fired, oil-fired plant test. The result show that the gas-generator hot central plant recycling heat energy utilization increased by about 10% and emissions decreased by 43%.So the hear energy ut...
