Essential part of Stenter Machine widely used in Hot air Stenter machine. Generally Fabricated with MILD STEEL, ALUMINUM, STAINLESS STEEL Material Duly hydraulically tested ready to fit, easy to replace with existing heat exchanger.
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.

(1) the spiral wound tube heat exchanger is highly efficient and saves energy (steam). Internal unique reverse winding spiral coil structure, heat exchange in a current way, make fully condensing steam in the heat exchange tube bundle, do not need a second heat exchange, so it can save a lot of steam;
(2) spiral wound tube heat exchanger is stainless steel welding, it can bear high temperature and high pressure. Because the heat exchange tube bundle and shell are all made of stainless steel material, with uniform expansion coefficient, the maximum pressure is1.6 MPa, the highest heat-resistant is 400 â??,it will not cause deformation of the heat exchanger because of pressure and temperature; so there is no need to prepare the equipment to reduce the pressure and temperature. (3) its structure is compact, with small size, saving infrastructure investment; Lightweight and easy to install, the equipment can be connected directly to the pipe, reducing installation cost.
(4) the heat exchanger with Michael's (OWEN) turbulent buffeting frequency standard principle, the heat exchange tube bundle adopts the minimum clearance design, effectively eliminates the turbulent chattering phenomenon, prolongs the service life of the heat exchanger.
(5) the heat exchanger is low in scale with a low maintenance cost, with unique structure, unique surface treatment technology, and on both sides of the counterflow heat exchange medium, not only improving the integrated heat transfer coefficient but also with self-cleaning function and low scale tend. The method of chemical descaling can be used to clean the heat exchanger, which can save time, power, cost and effect.

Plate heat exchanger is mostly parallel or counter-current flow mode. Select the number of processes and channels, the initial selection of cold, hot fluid flow and the number of channels, and thus calculated flow rates. Cold, hot fluid in the plate heat exchanger flow parallel to the heat transfer surface, no bypass, thus making the end temperature difference is small, the logarithmic mean temperature difference is large .
