With the development of the chemical industry, requiring gas recovered from the retort useful chemical products, for which will be completely separated from the carbonization chamber and the combustion chamber, after separating the chemical recovery plant carbonization chamber to produce a shortage of gas, net gas and then returned combustion chamber for burning or civilian. Focus on the development of late stage pressure ball machine coke ovens and the basic requirements of modern coke: coke oven is refining industrial furnaces, coke structure development generally go through four stages, namely piles of dry distillation (indigenous coking) , down draft type coke, coke oven waste heat and modern regenerative coke. China emerged as early as the Ming Dynasty with a simple method of producing coke process, which is similar to heap type refining charcoal, placed on the ground or underground coal furnace gas generated during carbonization and some rely on a direct result of the combustion of coal heat to refining coke, called piles or indigenous coking retort. Indigenous coking coke rate, high ash coke, coking long time, chemical products can not be recycled, but also causes environmental pollution, poor utilization. In order to overcome these shortcomings slag pressure ball machine, in the mid-19 th century will become the focus of the carbonization chamber and heating chamber separate oven with channel walls, indoor gas generated during carbonization of coal carbonization by this stream People in the combustion chamber, within the same air duct from the roof of the air mixture, flowing from top to bottom edge of the side burner, so the heat is transferred from the combustion chamber through the carbonization furnace wall material required for coal-fired oven called back, retorting . Coke oven is cold coke oven baking, masonry dried, dehydrated and heat-up stage, so that the furnace temperature more than 900 ~ 1000 ℃, for transition to production status coke oven preparation. Therefore, during the cold oven, thermal expansion and contraction between the very prominent. The quality of the oven, when the key is pressed brick oven from the cold into a hot ball machine, the expansion rate and expansion of masonry amount of processing, to ensure that coke will not be damaged due to expansion, in order to extend the oven Masonry life. Pressure the ball machine coke breeze coke oven is a more complex process, which includes thermal, iron and expansion amount of management, while during the hot oven but also for many projects involving construction, equipment installation, maintenance coal preparation and recovery plant started, the following discussion on several key issues. Success often fleeting. Last night was coming, went this morning. I look forward to a lifetime of happiness, because I finally realize hidden in the rough fate secret. Every failure, will make us more urgently seeking the right thing. Pressure the ball machine products in powder ball press machine in the production process, the user is most troubling is the powder molding problems, there are a lot of materials in order to maintain its various components, had to choose powder-ball coal briquetting machine, because the material can not be add water, it is more difficult to suppress them. In the initial pilot phase, often fails to suppress the ball, or the strength is not big enough, after a long period of trial summary, the final powder into the ball is no longer a problem. Right now a lot of the material are possible in the absence of water, the situation eventually pressed into balls, a lot of material in order to maintain its various components, had to choose Ball gypsum powder ball press machine, itself plagued by dry-ball The first problem is that the viscosity between dry enough, it is difficult to form the shape they are pressed together. So what we need to solve this problem, we want to increase the viscosity of the material between the viscosity we can also be interpreted as the density of the material between. Another chemical method is to change the physical state of the material, that is, to change the density of the material between the molecules, the more beneficial as promised degree of adhesion between the materials. Because it is difficult to suppress the molecular structure of a material change, so our situation as usual conservative, is the use of two pressurized method to suppress the material twice, as promised child for molding material is more appropriate.巩义富 China Machinery honest service has won wide acclaim from customers, authoritative, says it will do, no matter where you are in the world, our commitment to users are eternal.
