Tubular heating furnaces mainly include quick-installed tubular furnaces that directly heat crude oil and indirect-heated heat medium furnaces. Quick-installed tubular heating furnaces have great advantages in heating crude oil with a stable flow rate and low water content; It has advantages, but the operating cost and maintenance cost are high, and it needs to be equipped with heat medium circulation power system, heat exchanger, and heat pipe network.Prevention method for grinding cracks of vacuum carburizing and quenching gears The supporting cost of the system is high, and the nature of the heat medium needs to be replaced after the change, which increases the operating cost of the equipment; it is suitable for heat sources Places with more requirements and higher temperature requirements.Vacuum Brazing of EGR Stainless Steel Cooler The working process of the heating furnace is to convert the chemical energy of the fuel into heat energy. The heating furnace is mainly composed of two parts. One is the combustion system and the other is the heat exchange system. The heat exchange system exchanges the chemical energy of fuel combustion with the working fluid (heated medium) through various heating surfaces.HORIZONTAL SCISSOR STRUCTURE MITER METAL BAND SAW MACHINE CS-280S Mainly water jackets, torches, tube bundles, etc. Combustion system is the general term for fuel combustion equipment, which is composed of feed supply system, burner, furnace, air supply and induction system, tail flue, etc. No matter what kind of structural type of heating furnace, its heat exchange system requires sufficient heat transfer Heat area, better heat transfer effect, minimize fouling during operation, and reduce the operating index of exhaust gas temperature.HORIZONTAL MITRE BAND SAW MACHINE BS-1018R

The calciner is a device that disperses and suspends raw meal powder in the airflow, so that the fuel combustion and calcium carbonate decomposition process can occur within a short time (generally 1.5 to 3 seconds). It is a high-efficiency direct combustion solid-gas phase heat exchange device. Saw Hob Vacuum Furnace Application In the calciner, since the combustion of the fuel is carried out simultaneously with the heat-absorbing reaction of the material in a state of intense turbulence, the fine particles of the fuel float and burn at the same time, almost turning the entire furnace into a combustion zone. Therefore, no visible flame can be formed, but it is in a state of low-temperature flameless combustion at 820-900 °C.Vacuum hardened spring steel wire Since its appearance in the 1970s, the calciner has developed rapidly. So far, many types have appeared. According to their structure and working principle, they can be roughly divided into the following four types.Vacuum Heat Treatment Applications for Metal Machine Tools and Gear Parts The structure of the cyclone calciner is relatively simple. The structure of a typical swirl calciner is shown in the figure, which is composed of an upper swirl chamber, a lower swirl chamber and a reaction chamber. The inner surface is inlaid with refractory concrete and refractory bricks. There are 1~3 fuel nozzles in the middle of the reaction chamber, which inject fuel downward at an angle of 30°.Pay Attention to Vacuum Tempering to Improve the Quality of Quenched Parts
