The function and function of the calciner There are three main functions of the decomposition furnace: one is to make the fuel have sufficient burning time in the furnace, and the theoretical burning degree should reach 100%, so that the heat of the fuel can be released to the maximum. The second is to maximize the dispersity of the material through intense swirling and spouting, and to promote sufficient heat exchange with the hot gas in the dispersed and suspended state. The third is to promote the rapid decomposition of calcium carbonate, and the decomposition rate should reach more than 90%.Effect of Vacuum Annealing on Properties of 304 Stainless Steel Tensile Billets To achieve the above purpose, the dilute solid-phase gas flow in the decomposition furnace should have a relatively stable flow field, concentration field, temperature field and pressure field. The calciner has been developed and improved many times from its birth to today. There are various types of derivation and derivation, and there are 37 types in five categories. According to the movement form of air flow, it can be roughly divided into swirl-spray type, pre-combustion chamber-spout type, fluidized bed-spout type and suspension pipeline type. Vacuum heat treatment of electrical pure iron Various types of calciners rely on "cyclone effect", "spray effect", "suspension effect" and "fluid effect", so that the dilute in-phase air flow can be highly dispersed in the furnace, increase the contact area between the material and the hot air flow, and prolong the material flow. The residence time in the decomposition furnace can improve the combustion efficiency, improve the heat exchange rate and improve the decomposition rate of the raw meal entering the kiln. There are more than two types of airflow movement in the decomposing furnaces used in daily life. However, from a macro perspective, the technical principles of various calciners are basically the same, and with the maturity of decomposition technology and the mutual penetration of technology, various precalciners have similar structural forms in process devices and calciners.Atmospheric carburizing and low pressure vacuum carburizing of gears

Chain furnace knowledge The chain furnace is a fire-bed furnace with a wide range of applications, with a history of more than 100 years. At present, the capacity of domestic chain furnaces is 240t/h, and our company has achieved 160t/h hot water boilers.Deformation and Control of Carburizing and Quenching for Large Gears and Gear Shafts The chain furnace is a typical front-fed fuel boiler, and the grate moves slowly from front to back like a belt conveyor. The fuel descends from the coal hopper and falls on the grate, and travels with the grate. Air is introduced from below the grate from bottom to top, intersecting the direction of fuel supply. When the fuel passes through the coal gate, it is scraped to a certain thickness and then enters the furnace. After the fuel is radiantly heated in the furnace, it enters the combustion stage. 1.
