Simulative operation method of 450m<2> sintering machine ignition furnace

Abstract

The invention discloses a simulative operation method of a 450m<2> sintering machine ignition furnace. The method comprises an simulative operation training step and an identification step, and a computer program cooperatively matched with the simulative operation training step and the identification step is adopted; the identification step is used for auditing the simulative operation training step; the simulative operation method is characterized in that: the simulative operation training step comprises an ignition furnace normal operating step and an ignition furnace fault state and processing step, wherein the ignition furnace normal operating step comprises the following steps in sequence: (a) extinguishing the ignition furnace; (b) cleaning the ignition furnace by using nitrogen; (c) performing coal gas replacement on the ignition furnace; (d) performing a coal gas explosion experiment on the ignition furnace; and (e) igniting the heat-insulating ignition furnace; and the ignition furnace fault state and processing step comprises the following steps in sequence: (a) reducing the coal gas pressure of the ignition furnace; (b) further reducing the coal gas pressure of the ignition furnace; (c) stopping a combustion fan of the ignition furnace; (d) stopping an auxiliary fan of the ignition furnace; (e) reducing the pressure of compressed air for an instrument of the ignition furnace; and (f) powering off the instrument of the ignition furnace. According to the method disclosed by the invention, the learning cycles of new transferred workers and current operators are shortened.

Description

Technical field: [0001] The present invention is mainly used for 450m 2 The training of workers who operate the ignition furnace of the sintering machine. Background technique: [0002] 450m 2 The ignition furnace of the sintering machine is composed of an ignition section and a heat preservation section. Coke oven gas is used as fuel, and normal temperature air is used as combustion-supporting air. There are two rows of burners on the furnace top of the ignition section, which are arranged obliquely and crosswise. There are 13 burners in the first row and 14 burners in the second row. There are 4 temperature measuring holes on the furnace top of the ignition section. 4 pilot burners, 4 observation holes and a pressure measuring hole; there are 6 burners on the top of the insulation section, and 2 pilot burners, 2 observation holes and a pressure measuring hole on the side wall. Piping systems include air piping systems, gas piping systems, N 2 and release pipe syste...

Problems solved by technology

At present, the operator can only learn and train the ignition procedure after the inspection and fire extinguishing. There are only 3 to 5 inspections in a year, and the interval between each inspection is at least three months. The actual operation and learning of the ignition furnace program can only be carried out in a few opportunities

In actual operation, due to lack of proficiency in mastering the ignition furnace program, the ignition furnace has not been operated for a long time.

It not only prolongs the ignition operation time of the ignition furnace, but also sometimes makes the operation error of the ignition furnace occur.
