Can a certain amount of blast furnace gas be mixed into the coke oven gas heated by coke ovens? The purpose is: ① To dilute coke oven gas in order to improve top heating ； ②Save some blast furnace gas. Blast furnace gas has a low calorific value; when mixed with coke oven gas, it reduces the calorific value of the gas as a whole, requiring more gas to be used and generating more waste gas that carries away additional heat... To heat blast furnace gas, it needs to be preheated to a higher temperature in regenerative chambers. Under conditions that permit coke production, it can be mixed directly from the coke oven gas pipelines in the basement without prior preheating – but how much blast furnace gas can be mixed in at most?
A certain amount of blast furnace gas can be mixed into coke oven gas within a certain range. Introducing a certain amount of blast furnace gas can dilute coke oven gas, improve upward heating, and help save some of the blast furnace gas used. It should be noted, however, that the inclusion of blast furnace gas reduces its calorific value, requiring an increased amount of gas to be used; at the same time, it also generates more waste gas, which carries away more heat. To account for the inclusion of blast furnace gas, it is necessary to preheat it to a higher temperature in the regenerator in order to meet the requirements of coke production. If it is introduced directly from the blast furnace gas pipeline in the basement, the maximum amount of blast furnace gas that can be introduced needs to be considered. The exact amount of blast furnace gas that can be mixed in depends on the design and operating conditions of the coke oven; generally, reasonable process design and experimental verification are required. .
All of them can use blast furnace gas
