Title: Boiler fuel additive agent injection control device
Inventor: KASHIWAZAKI MASAMICHI
IPC: F22B37/00
Filed: 1988-07-25
Abstract: PURPOSE:To make it possible to perform stabilized and continuous operation by comparing stored boiler characteristic values, such as water spray quantity for desuperheater, exhaust gas volume for recirculation under each load with prespecified additive agent injection stop and permission conditions, and starting or stopping the injection of said additive agent when any measured value reaches one of the conditions described above. CONSTITUTION:Each detector 36 is designed to detect the steam temperature at the outlet of a superheater 17 and a reheater 18, the flow rate of recirculation exhaust gas, and spray water quantity for desuperheating. The detected values are input into an input circuit 32 of a control device 31 which comprises a microcomputer and the other devices. Each characteristic value in terms of boiler loads, and specified additive agent injection stop conditions and additive agent injection permission conditions are stored in a memory section 33. During boiler operation, additive agents from an additive agent tank 10 are injected into the fuel of a fuel supply pipe 1. However, when one of the characteristic values described above falls under the additive agent injection stop conditions due to the change in boiler loads, and additive agent injection pump 11 will come to a halt. When one of the characteristic values conform to a reinjection condition, the supply will be restarted. Therefore, the above construction makes it possible to prevent corrosion, allowing stabilized and continuous operation.

Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To enable easily reduction of parasitic resistors on source sides, without the loss of electric filed relaxation effect on drain sides, in the manufacture of a CMOS inverter with an LDD structure. SOLUTION: For example, when a gate polysilicon 32 is formed via a gate oxide film 29 on a P-type substrate 11, a dummy polysilicon wiring 33 is formed at the sometime in proximity to a source region.
