Definitions
- the invention relates to a device for the directed introduction of combustion air into the secondary air sole of a coke oven, which is formed by at least one collecting line for combustion air, which runs below the coke oven chamber of the coke ovens of a coke oven, wherein, this bus at least one branch in at least has a coke oven chamber, is introduced through the combustion air for complete combustion of the coking gas in the secondary air sole at least one coke oven, so that the combustion in the Koksofensohle is optimized and thus the coking process is controllable.
- each coke oven can be individually supplied with combustion air by means of corresponding adjusting devices, so that each coke oven can be individually supplied with combustion air during the coking process, which is of great advantage in view of the staggered coking process in coke oven chambers of a coke oven bank.
- the invention also relates to a method for the directed introduction of combustion air into the secondary air soles of at least one coke oven of a coke oven bank.
- Coke ovens of the "non-recovery” or “heat-recovery” type are equipped with a coke oven chamber, which consists of lateral coke oven chamber walls, a coke oven chamber floor, a coke oven chamber ceiling, which as a rule Gewölbeform owns and frontal coke oven chamber walls, the latter containing the coke oven chamber doors, which are intended for loading and on the opposite side of the coke oven chamber for discharge.
- the heating of these furnace types is done by the coking gas, which forms during the coking from the zukokokenden coal cake.
- the coke oven chamber is loaded during operation only up to a certain height, so that over the coal cake a gas space remains free.
- the forming gas space is also called Primärweraum, and serves to burn the resulting directly from the coal cake coking gas, which is partially burned with a substoichiometric amount of combustion air.
- the partially burned coking gas is passed through the partial combustion via side gas ducts in the flue gas ducts, which are located below the coke oven chamber, and also with openings for the inlet of combustion air, the so-called secondary combustion air, are equipped. In the flue gas ducts, the partially burned coking gas is completely burned with an excess amount of combustion air.
- the flue gas ducts which are located directly beneath the bottom of the coke oven chamber for heating, are also called secondary heating rooms. Examples of the non-recovery and heat-recovery type furnace types mentioned are US4344820A, US4287024A, US5114542A, GB1555400A and CA2052177C.
- the flue gas ducts located directly below the coke oven chamber become almost all embodiments supplied via the secondary air soles with combustion air, which are located below the flue gas ducts, and which are connected to the flue gas ducts via vertical channels, which are in a horizontal plane between the flue gas ducts and the secondary air sole.
- combustion air which from the atmospheric environment in the secondary air sole flows, preheated, and the openings that introduce the combustion air into the secondary air sole may also be controllable.
- the combustion of the coking gas and consequently the temperature development in the coke oven chamber also behaves. Since the output of the amount of coking gas depends on the type of coal used, this can not be influenced by the operator of the coke oven bank for a given type of coal. However, there is often a desire on the part of the operator of a coke oven bank or plants to influence the coking behavior and the temperature development in a coke oven chamber, since this can decisively influence the quality of the coke and the economy of a coke oven bank. The only way to influence the course of coking in a coke oven chamber, therefore, is the control of the supplied quality and amount of combustion air.
- Another problem is that although the production of coke in a coke oven bank formed of multiple coke oven chambers is carried out continuously, the loading and unloading of the coke oven chambers is performed at different times. Since the coking in a single coke oven chamber proceeds in batches, the coking processes in the individual coke oven chambers are carried out with a time offset, so that the output of coke for the entire coke oven bank is approximately constant. As a result, the air requirement is also offset in time in the individual coke ovens.
- the present invention solves this problem by a device which is formed by a manifold for combustion air at the Koksofenschfront, wherein the manifold is located at the front wall of the coke oven chamber at the level of the secondary air sole, and has at least one branch through which the Combustion air is passed via a side pipe in the secondary air sole.
