摘要: The present invention solves problems of securing high-temperature strength at elevated temperatures and of preventing steam leakage that arise when high-pressure, high-temperature steam is used for driving a steam turbine, and problems of preventing the occurrence of rubbing due to the suppression of the excessive elongation difference and of minimizing steam leakage from shaft seals. A double-wall casing structure is arranged at an area corresponding to stages from a high-pressure first stage (7) to a predetermined high-pressure stage arranged on an upstream side of a high-pressure final stage (8); and a single-wall casing structure is arranged at an area corresponding to stages which follows said predetermined high-pressure stage.

摘要: A selective catalytic reduction (SCR) system that can prevent fixation of urea solution to an interior of a dosing valve when the urea solution is not injected through the dosing valve. An SCR system closes a dosing valve when the exhaust gas temperature is lower than a temperature at which an SCR catalyst becomes active and is provided with a fixation prevention system that opens the dosing valve and controls a supply module to feed the urea solution in the dosing valve back to a urea tank to prevent fixation of the urea solution to the interior of the dosing valve, when the exhaust gas temperature is equal to or higher than a temperature at which the urea solution crystallizes and lower than the temperature at which the SCR catalyst becomes active.

摘要: An exhaust gas purification system includes a diesel particulate filter (“DPF”) which collects particulate matter (“PM”) in exhaust gas, an exhaust pipe injector which performs exhaust pipe injection, and a DPF regeneration control unit which performs temperature rise control of an exhaust gas temperature by the exhaust pipe injection to regenerate the DPF when the PM collected by the DPF exceeds a fixed amount and which, during the regeneration, integrates an amount of time during which the exhaust gas temperature exceeds a PM combustion temperature and completes the regeneration when an integrated value thereof reaches a set regeneration completion value. The DPF regeneration control unit aborts the regeneration when, during regeneration, a total amount of the exhaust pipe injection exceeds an upper limit before the integrated value.

摘要: An exhaust gas purification system with which a frequency of diesel particulate filter (“DPF”) regeneration requests can be reduced during long low idle regeneration, thereby improving convenience, including a control unit that performs regeneration control on a DPF provided at an exhaust pipe of an engine. The control unit includes a particulate matter (“PM”) accumulation amount predictor for predicting the amount of PM accumulated by calculating a cumulated value of the PM in an idling state. The control unit starts calculating the cumulated value of the PM by the PM accumulation amount predictor after a first predetermined time has elapsed since a detection of the idling state.
