Abstract: The invention discloses a gas lift-based liquid metal cooling pool-type reactor multifunctional reactor internal thermal separation system. According to the gas lift-based liquid metal cooling pool-type reactor multifunctional reactor internal thermal separation system, when a reactor is at normal operation conditions, a thermal separation valve is opened, an auxiliary heating valve is closed, a gas filter and a gas compressor are turned on, and thermal separation effect is realized by the gas lift-based liquid metal cooling pool-type reactor multifunctional reactor internal thermal separation system; when the reactor is at low-power running or shutdown condition, the auxiliary heating valve is opened, the thermal separation valve is closed, the gas filter, a gas heater, and the gas compressor are turned on, and auxiliary heating effect is realized by the gas lift-based liquid metal cooling pool-type reactor multifunctional reactor internal thermal separation system The gas lift-based liquid metal cooling pool-type reactor multifunctional reactor internal thermal separation system is simple in structure; activation is convenient; cold and hot pool separation and reactor internal cooling agent auxiliary heating of liquid metal cooling pool-type reactors can be realized at the same time; the complexity of reactor system structure is reduced effectively; reactor economical efficiency and security are increased; application range of the gas lift-based liquid metal cooling pool-type reactor multifunctional reactor internal thermal separation system is wide; the gas lift-based liquid metal cooling pool-type reactor multifunctional reactor internal thermal separation system is suitable for both liquid metal cooling pool-type reactors with forced circulation, and liquid metal cooling pool-type reactors with natural circulation.

Power generating plant using blast furnace gas as fuel

Abstract: PURPOSE:To improve plant efficiency and to prevent low temperature corrosion of a blast furnace gas heater, by arranging a blast furnace gas heater utilizing steam extracted from a turbine and a blast furnace gas heater utilizing of exhaust gas in series on a blasting furnace gas flow system. CONSTITUTION:Extracted steam from a turbine 2 is led to a blast furnace gas jeater 10 utilizing turbine extracted steam, which is load to a low pressure heater 5. Exhaust gas comes out of a coal economizer 13 and passes through an exhaust gas blast burnace gas heater 9 and reaches a stack 12 through an air preheater 11. In this manner, plant efficiency can be improved drastically and thermal energy to be thrown away to a condenser 3 and that of the exhaust gas can be recovered. Then, low temperature corrosion of a metal at the low temperature part of the exhaust gas blast furnace gas heater 9 can be avoided.

Air conditioner having supplemental gas heater for outdoor coil

Abstract: An air conditioner includes a compressor, an indoor heat exchanger, an expansion tube, and an outdoor heat exchanger interconnected by refrigerant conduits for operation in cooling and heating modes. In a cooling mode, the outdoor heat exchanger conducts ambient air horizontally across heat exchange coils. In a heating mode, the outdoor heat exchanger conducts heated air from an auxiliary gas-fired heater upwardly across those same coils. The outdoor heat exchanger includes movable blades for creating the horizontal and vertical air flow passages for the cooling and heating modes.

Method and device for regenerating gas for carbon dioxide gas laser

Abstract: PURPOSE:To continue the regenerative action of a noble metal catalyst, and to continue the regenerative throughput capacity of a mixed gas for a prolonged time by bringing CO and O2 and NOx in the mixed gas used for a laser device into contact with the catalyst at a temperature, where the degree of poisoning by NOx is reduced, and recirculating these gases to the laser device. CONSTITUTION:A mixed gas used for a carbon dioxide gas laser device 7 is heated at a temperature of 200-350 deg.C by a gas heater 3, and catalytically reacted with a noble metal catalyst in a reactor 4. The heat of reaction generated is utilized for preheating an unreacted mixed gas. The mixed gas after the reaction is cooled by a gas cooler 5 up to a temperature capable of being used for laser oscillation, passed through a filter 6 to prevent dust, and returned to the laser device 7 again. Consequently, since the mixed gas is cooled to a temperature, where the degree of the adsorption of NOx is lowered, the regenerative action of the catalyst can be continued for a prolonged time. When the activity of the catalyst is reduced, NOx adsorbed to the catalyst is decomposed by an He-CO-O2 mixed gas.
