Title: Gas discharging device for combustion equipment
Inventor: TSUGAWA AKIHISA
IPC: F23L17/04
Filed: 1994-09-20
Abstract: PURPOSE: To prevent accident caused by flowing-in of discharged gas into a room and inform a time of repairing operation or a replacement operation for a discharging cylinder by a method wherein a leakage of the discharged gas is detected under a utilization of an electrical shutter and a fan and an alarm is produced. CONSTITUTION: In the case that a combustion equipment 1 is newly installed, or repaired, a reading-out value of a pressure gauge 8 during rotation of a fan 4 when an electrical shutter 7 is closed is stored in a memory as an initial value PO during the case that an operation is carried out. When an operation of the combustion equipment is started every time, a control device 9 measures automatically an increased value of a pressure P caused under a rotation of the fan 4 when the electrical shutter 7 is closed, compares the increased value with the initial value PO and if the pressure P is decreased, it detects an occurrence of leakage of discharged gas caused by certain causes such as a removal of a discharging cylinder 3 or its corrosion and the like and then generates an alarm.  With such an arrangement as above, it is possible to inform a time of performing a repairing operation for the discharging cylinder 3 or its replacing operation as well as to prevent occurrence of accident caused by flowing-in of the discharged gas into a room.
