Heat Staking Machines Are Beneficial When Joining Two Parts That Consist Of Different Material Which Cannot Normally Be Ultrasonically Welded.
In Heat exchanger system, the new and latest type of compact and effective model Heat exchanger is plate type heat exchanger. Another type of heat exchanger is the plate heat exchanger. One composed of multiple, thin, slightly-separated plates that have very large surface areas and fluid flow passages for heat transfer. This stacked-plate arrangement can be more effective, in a given space, than the shell and tube heat exchanger. Advances in gasket and brazing technology have made the plate-type heat exchanger increasingly practical. In HVAC applications, large heat exchangers of this type called plate-and-frame; when used in open loops, these heat exchangers are normally of the gasketed type to allow periodic disassembly, cleaning, and inspection. There are many types of permanently-bonded plate heat exchangers. Such as dip-brazed and vacuum-brazed plate varieties, and they are often specified for closed-loop applications such as refrigeration. Plate heat exchangers also differ in the types of plates that used, and in the configurations of those plates. The closely spaced metal heat transfer plates have troughs or corrugations. Which induce turbulence to the liquids flowing as a thin stream between the plates. The plates have corner ports. Which in the complete plate pack form a manifold for even fluid distribution to the individual plate passages. As an exclusive feature, parallel flow heat exchanger plates have interlocking gaskets. In which upstanding lugs and scallops are sited intermittently around the outside edges. The seal between the plates is established by a peripheral gasket which also separates the thru port and flow areas with a double barrier. The interspaces vented to atmosphere to prevent cross-contamination in the rare event of leakage. Plate heat exchanger, consists of a stationary head and end support connected by a top carrying bar and bottom guide rail. These form a rigid frame, which supports the plates and moveable follower. The closely spaced metal heat transfer plates have troughs or corrugations. Which induce turbulence to the liquids flowing as a thin stream between the plates. The plates have corner ports, which in the complete plate pack form a manifold for even fluid distribution to the individual plate passages.

Flue Gas Heat Recovery Study Every 20C heat recovered from Flue Gases translates to ~1% improvement in Boiler efficiency. For flue gases with SOx and/or sooty, particulate material Conventional heat exchangers suffer from cold spot and SOx condensation corrosion due to cold spots. Also, sooty flue gases offer challenges with respect to cleaning and maintenance in conventional exchangers. HPHE operates at isothermal conditions and hence does not suffer from cold spot formation. Flue gases can be cooled close to the condensation temperature allowing higher heat recovery. Automated or manual in-situ cleaning of HPHE makes it an ideal exchanger for sooty flue gases. This study focuses on a boiler producing 6 t/h saturated steam at 10 bars. Two fuel cases have been considered for this study, Briquettes and Natural Gas. Briquette fired boiler The flue gases will contain a high amount of particulate/soot. The evaporator section of the HPHE for this case has non finned smooth heat pipes and is fitted with an Ultra-Sonic soot blower. The graph on the right shows the Cost Saved per year and HPHE CAPEX for 60, 80, 100, 120 �°C heat recovered from flue gases, assuming the flue gas exits the boiler at 200�°C. Savings is calculated based cost of steam @ Rs 2.3/kg Savings is calculated based cost of steam @ Rs 4.2/kg Natural Gas fired boiler The HPHE for this case will have fins in the evaporator section to improve the overall heat transfer. In case there is SOx in the flue gas, the gases can be cooled to a temperature close to the dew point at the stack exit. The graph on the left shows the Cost Saved per year and HPHE CAPEX for 60, 80, 100, 120 �°C heat recovered from flue gases, assuming the flue gas exits the boiler at 200�°C. The shown Savings and CAPEX figures are estimated values. Connect with us to find our the exact cost savings and HPHE CAPEX for your project.
Industrial equipment Brazed plate heat exchanger is a new type of high-efficiency heat exchanger made of a series of metal sheets with a certain corrugated shape stacked and brazed. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. Compared with the conventional shell and tube heat exchanger, its heat transfer coefficient is much higher under the same flow resistance and pump power consumption, and it has a tendency to replace the shell and tube heat exchanger within the applicable range. Applications: Refrigeration: used as condenser and evaporator b. HVAC: intermediate heat exchangers used in conjunction with boilers, intermediate heat exchangers in high-rise buildings, etc. c. Chemical industry: soda ash industry, ammonia synthesis, alcohol fermentation, resin synthesis cooling, etc. d. Metallurgical industry: heating or cooling of aluminate mother liquor, cooling of steelmaking process, etc. e. Machinery industry: cooling of various quenching fluids, cooling of reducer lubricating oil, etc. Design Parameters Flow range: 1-2000 m3/h Working pressure: vacuum-8.2MPa Operating temperature: -195-538C Interface size: 1"-DN300 welding, flange, thread and other connection forms Corrosion resistance: Welding seal without rubber gasket, choice of various metal and alloy materials, super corrosion resistance, longer service life. Application field: Crude oil, natural gas purification and chemical products; chemical industry; pharmaceutical and specific chemicals; injection control systems; HVAC, district heating, thermal power plants; food processing; cooling tower heat recovery Process requirements Pickling temperature: Raising the pickling temperature is conducive to improving the descaling effect. If the temperature is too high, it will aggravate the corrosion of the pickling solution to the heat exchanger plates. Through repeated tests, it is found that the pickling temperature should be controlled at 60. 2) Concentration of pickling solution: According to repeated tests, the pickling solution should be prepared according to the concentration of formic acid 81.0%, water 17.0%, buffer 1.2%, and surfactant 0.8%, and the cleaning effect is excellent. 3) Pickling method and time: The pickling method should be carried out by a combination of static soaking and dynamic circulation. The pickling time is static soaking for 2h first, and then dynamic circulation for 3~4h. During the pickling process, samples should be taken frequently to test the pickling concentration. When the difference between the two adjacent test concentrations is less than 0.2%, the pickling reaction can be considered to be over. 4) Passivation treatment: After pickling, most of the scale and metal oxides on the surface of the plate heat exchanger will be dissolved and fallen off, exposing new metal, which is very easy to corrode. The sheet is passivated.

About Induction Melting Furnace Induction Melting Furnace is major steel producing technology using scrap & sponge iron (directly reduced iron) as main raw material. This technology contributes significant steelmaking capacity in secondary steel sector in India and abroad. It has Air Pollution Steel scrap comes from various sources and generally has contaminants/coating etc on it. When this scrap is heated contamination/coating etc. disintegrates from steel and comes out either as slag or becomes air borne, thus causing air pollution. The major source of Air Pollution is : 1.
