摘要： The method of reducing a nitrogen oxides content of a flue gas generated on firing of a rich gas or combination coke oven having a plurality of heating walls forming dual heating flues, in which a single stage or multistage combustion takes place, and also having a plurality of regenerators for recovery of flue gas heat and preheating of an underfiring medium, includes the steps of mixing one portion of the flue gas drawn from one flue of the dual heating flues with the underfiring medium, gas and/or air, prior to or on admission to the other flue of the dual heating flues, or a regenerator connected with it, and circulating another portion of the flue gas additionally inside the dual heating flues. The method advantageously also may include recirculating externally at a predetermined flow rate the one portion of the flue gas considering the recirculating of the other portion of the flue gas inside the dual heating flues and controlling the recirculating so that a flame temperature in the heating flues is kept constant based on a heat balance in the heating flues, and feeding, during rich gas firing of the combination coke oven, the one portion of the flue gas recirculated externally only to those of the regenerators, which receive the underfiring media during lean gas operation, and, during rich gas operation, only to every second one of the regenerators.

摘要： A clamping system for preventing detrimental tensile and shearing stresses in heating walls used for example as partitions in industrial furnaces, comprises clamping plates adjoining opposite end faces of a heating wall plate, yoke-shape beams facing each clamping plate and interconnected by cross tie rods, and pressing elements between the beams and the clamping plates. The bias of the pressing elements is adjusted so as to decrease from the center of the clamping plate towards the upper and lower edges of the heating wall plate, the material of respective clamping elements being selected such as to keep the interfering forces within the limits of 5 to 20% of the original clamping forces, the resultants of the clamping forces being directed to the marginal area of each clamping plate, and the roughness in excess of 2.5 millimeters between the clamping plate and the heating wall plate being reliably compensated.

Discharge openings are provided at at least three levels for supplying each flue. A base discharge opening is provided at the flue base directly connected to regenerators. Hollow communicating channels are defined for connecting the regenerators to discharge openings located above the flue base. The hollow communicating channels are preferably formed in each communicating wall connected to a discharge opening leading only to one adjacent flue. The regenerators for preheating air are subdivided in a longitudinal direction of the oven with one part being connected to the base openings at the flue base and another part being connected to the hollow communicating channels. A regulating system is provided for setting the amount of air for the two parts separately. Pressure blocks are provided for setting the air distribution at the discharge openings provided above the flue base. The circulating flow openings are arranged at the foot of each flue in a hollow communicating wall between adjacent flues to provide ascending and descending flow.

摘要： In order to preserve the quality of treated coking coal, the drying and preheating operation is performed in consecutive stages. For this purpose, a set of superimposed containers is provided with vertically oriented pipes for a heating medium, the pipes in each container having separate inlets and outlets. The bottom region of each container is further provided with horizontally directed pipes having separate inlet and outlet for receiving a pressure medium which is discharged into the bottom region of each container to produce a whirling bed of the coal. In this manner, the coal is preliminarily dried in the uppermost container, then additionally dried and preheated in the intermediate container, and heated to the desired final temperature in the lowermost container.

摘要： Coking system, wherein the coking blends particularly based on hard coal, are fed batchwise to a reactor (1), which is heated indirectly by heat recovery in regenerators (I, II) or recuperators, whereby the reactor is built as a high-capacity coking reactor (100), several high-capacity coking reactors are combined to form a reactor block and the high-capacity coking reactors are built as mutually independent modules, whereby each module can be operated or optionally replaced independently of the neighboring modules, with little or no impairment of the operation of the neighboring modules. The individual reactors are independently operatable in terms of statics and heat supply. The regenerators, or recuperators (I, II, R, R') can be arranged laterally or underneath the reactor chamber. Neighboring reactors can have a common intermediate wall (2). The reactor chambers have a width of at least 0.7 m, a height of at least 8.5 m and a length of at least 18 m.
