Abstract
PURPOSE: To save a fuel and smooth the operation without affecting the production and temperature distribution among flues, by carrying out the operations of reducing and cutting off the fuel flow rate at a period staggered from the standard one to correct the lag between the ends of coking periods varying for each oven chamber.
CONSTITUTION: Coal is carbonized in a horizontal chamber oven by carrying out the operations of reducing and cutting off the fuel flow rate at a period staggered from the standard one to eliminate the lag between the ends of coking periods of the respective chambers in changing the quantity of heat supply according to the quantity of heat required. For example, the coking period is staggered to 11.5 and 11.3hr in a carbonization chamber 400mm wide and 4.5m high comprising regenerators of volume 20m3/chamber under the following normal operating conditions: Fuel gas: a mixed gas of blast furnace gas with coke oven gas. Carbonization time (time from the charging of fuel to the reduction of fuel flow rate): 20hr. High level of fuel flow rate: 1.5 times that of the conventional method. Low level of fuel flow rate: 0.1 that of the conventional method. Preheating time: 1hr. Standard coking period: 18hr.
