Document Type and Number:
Japanese Patent JP2002220620
Kind Code:
A
Abstract:
To provide a method for controlling a furnace pressure, which can surely prevent invasion of air into the heating furnace.
This method for controlling the furnace pressure, which arranges a recuperator in the way of a flue for leading exhaust gas in the heating furnace to the outside, and which supplies a dilute air to the recuperator side in the flue, in order to protect the recuperator from high temperature atmosphere, when preheating the combustion air supplied to a burner which is a heat source of the heating furnace, with the recuperator, is characterized by controlling the amount of dilute air flow according to an exhaust gas temperature at the recuperator side and a combustion load of the heating furnace.
