PURPOSE:To provide a heating furnace which can increase an amount of the air urgently fed to a furnace, by providing air feed ports which can be momentarily opened through remote control or by means of an interlocking system. CONSTITUTION:About 1-10 air feed ports 1, which can be momentarily opened, are formed in a heating furnace. When steam is urgently needed, or when a heat quantity at an economizer part is needed urgently, the air feed ports 1 are opened according to an amount of the air required through remote control. In this constitution, if the air is introduced into a furnace and an amount of gas introduced to the economizer part is increased, a quantity of heat to the economizer part is increased, and as a result, an amount of steam generated is increased, and such increased steam can compensate for steam consumed in a plant. |
