    For economical burning of cement clinker, the material is divided into two streams which pass separately from one another through the preheating and calcining system and then together through the rotary kiln and cooler. The combustion air preheated in the cooler passes directly into one branch of the calcining system, and the combustion air preheated in the rotary kiln is fed with the combustion gases to the other branch of the calcining system. The equipment for carrying out the process comprises a calcining system with two branches (3) and (4). Only the branch (4) of the calcining system is connected directly to the clinker cooler (2) by the pipe (15) for feeding the combustion air. The other branch (3) of the calcining system is connected to the rotary kiln (1) by the pipe (12) for feeding waste gases and combustion air. the feeding of the material streams from the two branches (3) and (4) to the rotary kiln (1) can be designed in various ways. As a result of the novel arrangement, the production operation is made flexible, and the heat losses and pressure drops in the plant are minimised. <IMAGE>

    The invention relates to the production of building materials, primarily to the methods of burning cement clinker and devices for their implementation.
    There is a known method of burning cement clinker in rotary kilns by dividing the raw material into two ptotes, including separate heating, calving of the material before the rotating peeler with air supply for burning heat from the refrigerator, burning and cooling fl. The method implements a device containing a rotary kiln, a refrigerator, two branches of mine heaters, one of which is connected to the furnace via a calcinator and a refrigerator through an air duct, and the reactor is connected to the furnace through a duct. The disadvantage of this method is low productivity and inertia is independent of the world.
    The purpose of the invention is to increase productivity and provide independent process control.

    This is achieved by using the method of burning cement clinker in a rotary kiln by dividing the raw material into two streams, including separate heating, calcining the material S neipeTt rotary kiln with a subfloor i B6e ta jSfH: Calcination of both material flows is carried out separately, and a supplemental supply of baking from the refrigerator is carried out through a rotary kiln to burn the fuel during combustion in the ozi from the material flows. Such a method can be carried out by means of a BpaiiiiaidD yTocfl, hbLodilbnik ;, mine branches according to Dbgravatovol, one of which is connected to the furnace through a calciner and with a xmüdilnik through an air duct, and the second is connected to the furnace through a gas duct 7; h ,; moreover, the second branch is provided with an additional decanter connected to the rotary kiln by means of a pipe for the hearth and the material. In the drawing, a diagram of an apparatus for carrying out the method, The apparatus comprises a rotary tube furnace 1, a cooler 2, branches 3 and 4 of the calcination system to the branches 5 and 6 of the preheater. In both branches 5 and 6 of the preheater, the material is fed by loaders 7, 8, flows down, while it takes fienno waste gas and preheats, From branches 5 and 6 of the preheater, it is supplied through pipes 9 and 10 to branches 3 and 4 of the scaling system, where the bulk of the HtipyeTCH sludge material is due to the heat of the fuel that the burners 11 and 12 of calcination give. Already calcined material goes through pipes 13 and 14 to a rotating tube furnace 1 to finish the process of quenching and direct burning in a rotating furnace 1, which uses the heat of combustion of the fuel supplied by the burner 15. The calcined material is fed through the head part 16 of the furnace to cooler 2 where it is cooled in the air flow. The cooled material escapes from cooler 2 through bath 17. Air necessary for cooling the material enters cooler 2 through inlet 18. Heated air is separated into and two streams, one stream through conduit 19 for combustion air, is directly supplied to branch 4 of the calcination system, through head 16 of the tube furnace 1. This air flow serves to squeeze the fuel in the rotating tube furnace 1 and in the branch 3 systems of Calcium Syndrome. The combustion of the fuel supplied by the kiln burner G5 to the furnace1, occurs with a large excess of air. The combustion product is swept with excess air through an exhaust pipe 20 through a pipe 20 to lift air into gas for heating in the calcination system 3. Exhaust gases of both branches 3 and 4 of the system of cansing by the fans 21 to 22 are directed through pipes 23 to 24 for gas exhaust and with branching 5 and 6 of the heater 1, .4. And then through the exhaust pipes 25 and 26 and out of the device through pipes 27 and 28. In an alternative device version, the already calcined material from branch 3 of the Silvanization system is introduced into the second branch 4. In this case, the pipeline 13 for removal of material directly adjoins the branch 4 and, depending on the circumstances, to the pipeline 19 for supplying combustion air. In branch 4 of the calcination system, both material streams are homogenized from the rotary tube furnace 1, and a homogeneous mixture of calcined material is withdrawn through conduit 14. Claim 1, A method of burning cement clinker in a rotary kiln by dividing the raw material into two streams, including separate preheating calcining of the material in front of the rotary kiln with air supply for burning fuel from the refrigerator, burning and cooling, characterized in order to increase performance and independence of process control, the calcining of both material flows is performed separately, and the additional air supply from the chiller for combustion The calcining process in one of the material flows is carried out. through a rotary kiln.
