摘要： PROBLEM TO BE SOLVED: To provide a nitrogen oxide reduction method and an apparatus for a gas fired absorption refrigerating unit which can reduce the discharge of nitrogen oxides remarkably despite the simplification of the structure and operation. SOLUTION: A flow rate control orifice 12A is interposed on an air suction port duct 2 and an inlet pressure of a force blower 11 is set at -30mmAq during the MCR period. An exhaust gas recirculation duct 13 branched off an exhaust gas outlet of a gas-fired absorption refrigerating unit is connected to the downstream of the flow rate control orifice 12A of the air suction port duct. Then, the opening of a draft control damper 31 is adjusted properly to control the internal pressure of the exhaust gas duct 3 to -5mmAq to hold back an NOX value in an exhaust gas below a limit value.

摘要： PURPOSE:To prevent a water feeding temperature of cold water from being rapidly increased when an energization is stopped by a method wherein A valve is installed in a pipe between an outlet side of a turbo-freezer and a supply head, and a communication pipe is disposed at a suction side of a cold water circulating pump through a valve from between an outlet side of an absorption type freezer and an inlet side of the turbo-freezer. CONSTITUTION:Upon completion of a warming-up operation of a steam turbine 4, an amount of steam is increased and the number of rotation of the steam turbine 4 is gradually increased and in concurrent with this operation, a valve 11 is opened, water is supplied to a turbo-freezer 1 and then a valve 25 is closed. Absorption type freezer 2 finishes its warming-up operation, it shows a fast rising capable of sufficiently following up an increased capability of the turbo-freezer 1, resulting in that a water feeding temperature in a supply header 8 is scarcely disturbed and it shows the same degree of capability as that of the normal turbo-freezer. In the case of stopping operation, a valve 13 for the steam turbine 4 is closed and the turbo- freezer 1 is stopped. Upon stopping of the turbo-freezer 1, the valve 11 is closed, the valve 25 is opened and water is supplied only to the absorption type freezer 2 so as to perform a dilution operation. Although this dilution operation is continued for about 20 to 30 minutes, the turbo-freezer 14 may act as a cold water precooler and so a water feeding temperature of the supply header 8 is not disturbed.

摘要： PURPOSE:To increase a thermal efficiency of an entire cold or hot heat source plant by a method wherein as a driving heat source, an absorption type freezer for taking out vapor from a low pressure vapor head of a heating vapor supplying device is provided, cold water is let flow in series to the absorption type freezer and a compression type freezer so as to enable a cooling to be attained. CONSTITUTION:A compressor 13 for a compression type freezer B is driven by a power force generated at a steam turbine 9 and then cold water is cooled with an evaporator 14. Heat removed from the cold water is transmitted to a cooling water 25 with a condenser 15. An absorption type freezer C takes driving vapor from a low pressure vapor header through a low pressure vapor pipe 12 so as to cool the cold water. Heat removed from the cold water is transmitted to a cooling water 24. Driving vapor gives heat to the absorption type freezer C and flows into a hot-well tank 22 as drain. The cold water is used as a cooling heat source for a heat demanding part 26, its temperature is increased and the cold water passes through a cold water return pipe 17, flows into the absorption type freezer C. The cold water is cooled down to an intermediate temperature, passes through a cold water pipe 18, further cooled with the evaporator 14 of the compression type freezer B, cooled down to a predetermined temperature and then the cold water is forcedly sent to the heat demand part 26 by a pump 16.
