Title: Explosion prevention method for exhaust heat boiler
Inventor: KATO KEIJI
IPC: F23N5/00
Filed: 1985-06-07
Abstract: PURPOSE:To prevent explosion by measuring oxygen concentration in the combustion exhaust gas at the combustion exhaust gas outlet and supplying air to the combustion chamber of an exhaust heat boiler in order to hold the oxygen concentration above a set value when the oxygen concentration falls below the set value. CONSTITUTION:An electromagnetic valve 10 is excited when the oxygen concentration in the exhaust gas is normal, that is, since the working air has pushed the rod 12 of the cylinder 11 to the right, the emergency air intake valve 15 connected to the rod 12 through a wire 13 goes down vertically to close the emergency air intake opening 14 which communicates with the combustion chamber. On the other hand, when the electromagnetic valve is freed from excitation by the signal from a control device that the oxygen concentration in the exhaust gas is lowered, the working air pushes the rod 12 of the cylinder 11 to lift upwards the emergency air intake valve 15 and the emergency air intake opening 14 is opened and the outside air is led in. With this arrangement the oxygen concentration in the combustion gas in the combustion chamber of the exhaust heat boiler is restored to its normal condition and explosion can be avoided.
