Zusammenfassung:The invention provides a pulverized coal furnace tiny-oil ignition combustion method which mainly solves the problem that the existing ignition method can not be applied to less oil ignition of a W-flame cyclone rich-thin pulverized coal burner. The pulverized coal furnace micro-oil ignition combustion method comprises the following steps: 1) leading pulverized coal in a main pulverized coal pipeline into a micro-oil ignition device arranged in a first secondary pulverized coal pipeline for ignition; and 2) after ignition is finished, switching a change-over valve on the main pulverized coal pipeline, and sending the pulverized coal air current into a secondary pulverized coal pipeline. The method has wide coal kind adaptability, low operating cost, low energy consumption and high reliability and is favorable for environment protection.
