Tube heating furnace is one of the important devices in oil refining and chemical production. Its task is to heat the raw material oil to a certain temperature to ensure the smooth progress of the next process.Vacuum brazing of surgical forceps - heat treatment process Therefore, the outlet temperature of feedstock oil is often selected as the controlled parameter, and the fuel flow rate is the control variable. In the temperature control system, the disturbances that affect the outlet temperature of feedstock oil include feedstock oil flow rate, feedstock inlet temperature, fuel pressure, and fuel pressure.Aluminum alloy micro-channel cooling plate vacuum gas quenching The system controls the opening of the fuel valve according to the temperature change of the raw oil outlet, and controls the crude oil outlet temperature at a specified value by changing the fuel flow rate. It is a simple control system. S380 BAND SAW BLADE SHARPENER GRINDING MACHINE After the fuel flow changes through three volumes, the outlet temperature of the raw material oil changes. The time constant of this channel is very large, about 15 minutes, and the reaction is slow.

High-purity corundum furnace tube, while using its high-purity and high-temperature characteristics, we must follow the inherent characteristics of corundum material (relatively poor thermal shock resistance, not resistant to rapid cooling and rapid heating), and operate with caution during use. Operation will cause the furnace tube to burst. The reasons for the explosion of the furnace tube are analyzed as follows:LARGE CNC HORIZONTAL LATHE 1. The temperature difference is too large 1. When using a high-temperature furnace tube, the heating and cooling speed is controlled at 5 degrees per minute, the slower the better. Rapid cooling and rapid heating is one of the main reasons for corundum furnace tube breakage, and the operating temperature should generally not exceed 1650°C;HIGH PRECISION CNC LATHE 2.

According to the movement form of the main air flow in the furnace, there are four basic types of calciner: swirl type, spray type, suspension type and fluidized bed type. In these four types of calciners, raw materials and fuels are dispersed in the airflow by "swirl effect", "spray effect", "suspension effect" and "fluidization effect" respectively.VERTICAL METAL BAND SAWING MACHINE Most of the calciners developed in the early stage mainly rely on one of the "four effects" mentioned above. Later, various types of calciners penetrated each other technically, so most of the current calciners tend to use the "comprehensive effect" of the above effects, in order to optimize the heat transfer, mass transfer, momentum transfer and chemical energy transfer in the calciner. VERTICAL CROSS CUTTING PULLEY TYPE METAL BAND SAW MACHINE Reaction process (referred to as "three passes and one reaction" process).

Industrial Electric Boiler A boiler is a mechanical device that uses heat from fuel or other energy sources to heat water into hot water or steam. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. VERTICAL CROSS CUTTING PULLEY TYPE METAL BAND SAW MACHINE The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power plant, or converted into electrical energy through a generator.

Before entering the pulverizer, go through the electromagnetic iron remover to remove the metal impurities in the coal. In the impact blow hammer mill, the mixed coal is crushed to a qualified particle size of less than 3mm, reaching 90%. The crushed qualified coking coal is transported by belt conveyor to the coke oven coal tower for storage for coking.CNC SERIES SUEFACE GRINDING MACHINE There is a tamping station under the coal tower. When the coke oven uses coal, it is directly loaded into the hopper of the distributing trolley from the nozzle of the coal tower. The capacity is about 1/2 the weight of coal cakes. The chute puts the coal evenly into the tamping coal box, and tamps the coal into briquettes. Coal cake density 1.1-1.2t/m3.PRECISION CNC SURFACE GRINDING MACHINE The crushed briquettes are sent to the coal loading car together with the coal box, and are transported to the carbonization chamber to be released from the oven.

Energy Saving Technology of Tube Heating Furnace With the development of industrialization, petroleum, as an important form of energy, drives the development of the entire petrochemical industry such as petroleum refining and petrochemical industry. So far, the petrochemical industry has been a pivotal sector in the world economy. In these industries, the main process medium heating furnace currently used is the tube furnace, which has the following main characteristics.Vacuum heat treatment of electrical pure iron Due to the flow in the tube, the heated medium is limited to gas and liquid. Usually these gases or liquids are usually flammable and explosive substances, which are relatively dangerous and the operating conditions are relatively harsh. The heating method is mainly direct type, the fuel is liquid or gas, the operation period is long, and the operation is continuous and uninterrupted.Effect of Vacuum Annealing on Properties of 304 Stainless Steel Tensile Billets Heap furnace, which refers to the principle of kettle steamer. The heat-absorbing surface is a group of tube bundles, and the connecting elbows between the tubes are also placed in the furnace. Since the burner is directly installed under the tube bundle, the heating intensity of each row of tubes in the furnace is uneven. When the bottom row of tubes is heated as high as 50000~70000kcal/m2·h, but the top row of pipes is less than 800~1000cal/m2·h, so the bottom row of pipes is often burned through, and the joints between the pipes are easy to loose and leak, causing fires.Z3132 RADIAL DRILLING MACHINE The pure convection furnace was considered to be because the radiant heat was too strong, so it was changed to a pure convection furnace. All the furnace tubes are installed in the convection chamber, and the convection chamber is separated from the combustion chamber by a partition wall to prevent the furnace tube from being directly scoured by the flame. However, during the operation, it was found that the top row tubes of the convection chamber were often burned out, and the heating of the furnace tubes was still very uneven. This is because the high-temperature combustion flue gas fails to exchange heat with a heat-absorbing surface before entering the convection chamber, and the temperature at the entrance of the convection chamber is as high as 1000 °C.Z3032 RADIAL DRILLING MACHINE
