Title: Flue gas desulfurization method and device therefor
Inventor: YAMAGUCHI FUMIHIKO
IPC: B01D53/34
Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To reduce desulfurized wastewater to be produced by a desulfurization device and thereby dispense with the desulfurization and wastewater treatment by using the desulfurized wastewater separated from the desulfurization device as a slurrying agent of an alkali neutralizer. SOLUTION: Nitrogen oxides are removed from an exhaust gas EG generated when a high sulfur-containing fuel is burned in a boiler 1, by means of a denitration device 2 and then dust is removed from the exhaust gas EG by an electrostatic precipitator 4. Further, a sulfur oxide contained in the exhaust gas EG is neutralizes by a slurrylike alkali neutralizer NR at a desulfurization device 5 and this neutralized produce is separated/recovered as gypsum using a gypsum recovery device 7. In this flue gas desulfurization method, the desulfurized wastewater WW separated by the gypsum recovery device 7 is used as the slurrying agent of the alkali neutralizer NR.

IPC: F02D41/14
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To provide a brake failure diagnosing device capable of detecting the failure of an auxiliary brake including a mechanical failure. SOLUTION: When the failure of the non-stop operation of an exhaust brake occurs during ISC control ('YES' in S102), since a load is applied to a diesel engine, the value of an ISC integration correction injection amount QISCI is suddenly increased, and this sudden increase in the ISC integration correction injection amount QISCI during ISC control is determined by the integration correction calculation of the ISC control (S103), and the ISC integration correction injection amount QSICI larger than a set value KQISCFAIL is determined (S104). Thus, an exhaust brake failure flag is changed from OFF to ON (S105). Therefore, the failure of the exhaust brake including electric and mechanical failures is detected.
