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.

Stainless Plate Heat Exchanger: 1. Structural characteristics of stainless steel plate heat exchanger Stainless steel plate heat exchangers are mainly divided into flat plate heat exchangers and plate heat exchangers. The main advantages are reflected in the characteristics of easy disassembly, good cleaning, convenient maintenance, small size and small footprint. There are also many people asking whether to add an insulating layer. The heat loss of the stainless steel plate heat exchanger in the air is 1%, and the insulating layer is basically unnecessary. Second, the characteristics of stainless steel plate heat exchanger plates The stainless steel sheet is mainly formed by one-time stamping. What are the main advantages of doing so? 1. The corrugation depth of each plate is the same to ensure that each contact point can be well connected. 2. The weight of the heat exchanger equipment can be reduced, and a higher heat transfer coefficient can be obtained under the requirement of being able to withstand pressure. 3. There is no excessive punching area on the plate, and no invisible cracks will appear. 4. The thickness of the plate can reach 0.3mm. The plate of the stainless steel plate heat exchanger has a strong pressure bearing capacity, which can prevent the mechanical fatigue caused by the shaking caused by the vibration. Third, the advantages and disadvantages of stainless steel plate heat exchanger The main advantages of stainless steel plate heat exchanger are: 1. Scaling is not easy to occur, because turbulent water can effectively reduce the possibility of scaling. To prolong the working cycle, chemical cleaning methods are generally used for cleaning. It can effectively reduce human, financial and material resources. If you are not familiar with the fouling treatment method of plate heat exchangers, you can poke into this article to browse. 2. Compact structure and small size, can be used in multiple places. And the heat transfer is good, and the equipment is light in weight. 3. The speed of the fluid is uniform, and the material is heated during the period of time without overheating. The main disadvantages of stainless steel plate heat exchangers are: 1. As mentioned above, the thickness of the sheet is thinner and the pressure bearing capacity is lower, especially the contact points formed between the corrugated sheets. With the prolongation of use time, the pressing size will exceed the installation size, which may easily lead to the formation of pressure pits at the contact point, which may lead to perforation and lead to the scrapping of the plate. 2. The space between the plates is narrower and the evaporation time used is shorter. If the hot and cold medium is exchanged between the liquid material and the corrugated plate, if the material is cut off, it will be in a coking state, and the coking material will block the cold material passage and cause damage to the sealing gasket.

A double pipe heat exchanger is a sort of heat exchanger which includes concentric pipes parted through a mechanical closure. The name of this heat exchanger indicates that it makes use of pipes to exchange heat among fluids. One pipe has hot fluid whilst the opposite pipe has cold fluid. These two fluids do not mix with each other as they are separated by pipes. This heat exchanger is likewise known as a jacketed u-tube, jacketed tube, hairpin, and pipe-in-pipe heat exchanger. The double pipe heat exchanger has a small pipe this is surrounded by some other huge pipes. One fluid glide withinside the small pipe, and the opposite fluid acts through the annulus among the 2 pipes. The internal wall of the small pipe is the heat switch surface. The complete warmness switch system takes vicinity withinside the huge tube. In this way, the internal pipe works as a conductive barrier. The outside facet consists of fluid gliding thru the tube facet or inside. This heat exchanger might also additionally have one pipe or a package deal of pipes (however decrease than 30 pipes). The huge pipe has decreased by 2 hundred mm in diameter. In a few conditions, the internal pipe has vertical fins to enhance the heat switch coefficient among operating fluids. Double pipe heat exchangers are used for small heat switch areas (e.g., 14 m2). The collection connection to elevate the heat switch place wishes greater area and greater accessories, which results in a better strain loss. In addition, it isnâ??t always viable to boom the number of fluid passages on each side. This heat exchanger isnâ??t always exceptionally appropriate for grimy drinks due to the fact the grimy liquid will clog it, and the cleansing of this exchanger could be very hard. The essential benefit of the double pipe warmness exchanger is that it has a smooth operation and easy design.

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.

Design Features & Benefits The spiral plate heat exchanger is made by rolling two long metal plates around a center core to form two concentric spiral flow passages, one for each fluid. The plate edges are welded shut so that each fluid stays within its own passage and there is no flow bypassing or intermixing. Channel plate width and spacing (gap between plates) are optimized for the specified duty, maximum heat transfer, and ease of access. The plate gap is maintained by welded spacer studs although some designs do not require them. Due to its inherent circular design and large surface area to volume ratio, the spiral heat exchanger offers unique advantages over other types of heat exchangers like the shell and tube. High Thermal Efficiency Single and long curving flow passages with a uniform rectangular cross-section ensure superior flow distribution, intense turbulence, and high heat transfer coefficients (50-100% greater than shell & tubes). Self-Cleaning Passages The spiral's single-flow passages induce high shear rates that scrub away deposits as they form. This self-cleaning effect reduces fouling and makes spiral heat exchangers ideal for handling tough fluids such as process slurries, sludge, and media with suspended solids or fibers. Countercurrent or Co-current Spiral heat exchangers normally operate in true countercurrent flow for close approaches and temperature crosses. Occasionally a co-current flow design has major benefits, especially in cooling or heating fluids prone to gelation, burn-on, freezing or similar skin temperature related fouling. Small Footprint & Easy Access The spiral heat exchanger is compact and requires minimal space for installation and servicing. Removable covers provide easy access to interior heat transfer surfaces for field inspections, routine maintenance, or manual cleaning if required.
